1 00:00:00,320 --> 00:00:05,760 Speaker 1: Welcome to Zero. I'm Akshatrati. This week sharkskins, plane wings 2 00:00:05,800 --> 00:00:20,880 Speaker 1: and novel things. One of the best things I get 3 00:00:20,880 --> 00:00:23,120 Speaker 1: to do in my job is to visit early stage 4 00:00:23,160 --> 00:00:26,520 Speaker 1: startups full of passionate people coming up with the solutions 5 00:00:26,560 --> 00:00:29,240 Speaker 1: to the climate problem. Some of them work with the 6 00:00:29,360 --> 00:00:33,520 Speaker 1: kind of headline grabbing tech you hear about all the time, batteries, 7 00:00:33,680 --> 00:00:37,320 Speaker 1: carbon capture, and even nuclear fusion. But there's all sorts 8 00:00:37,320 --> 00:00:40,080 Speaker 1: of weird and wonderful inventions out there which hope to 9 00:00:40,080 --> 00:00:42,760 Speaker 1: fill in the blank spaces in the net zero puzzle. 10 00:00:43,040 --> 00:00:45,839 Speaker 2: What we've made here is inspired by sharkskin. It is 11 00:00:45,920 --> 00:00:49,199 Speaker 2: much more simplified than actual sharkskin. So they're running in 12 00:00:49,200 --> 00:00:52,120 Speaker 2: this direction. Yeah, and if you your figuzz you can 13 00:00:52,159 --> 00:00:53,360 Speaker 2: hear that buzzing. 14 00:00:53,840 --> 00:00:57,040 Speaker 1: That's the voice of Henry Belinski, the founder of micro Tau, 15 00:00:57,560 --> 00:00:59,440 Speaker 1: and the high pitch noise you can hear it is 16 00:00:59,480 --> 00:01:03,640 Speaker 1: his finger running back and forth across a thin plastic film. 17 00:01:03,960 --> 00:01:07,960 Speaker 1: This is the startup's innovation, a textured film that imitates 18 00:01:08,160 --> 00:01:12,320 Speaker 1: sharkskin to reduce drag on airplanes. To the naked eye, 19 00:01:12,400 --> 00:01:15,600 Speaker 1: it's basically transparent, but when you look at it under 20 00:01:15,600 --> 00:01:20,039 Speaker 1: a microscope. You can see these tiny ridges known as riblets, 21 00:01:20,440 --> 00:01:24,800 Speaker 1: that mimic the pattern seen on sharkskin. Think about it 22 00:01:24,920 --> 00:01:27,959 Speaker 1: like a high tech wrapping paper, but for planes, all 23 00:01:27,959 --> 00:01:30,640 Speaker 1: in the service of using less fuel to fly and 24 00:01:30,680 --> 00:01:35,480 Speaker 1: thus produce fewer emissions. Aviation contributes about two percent of 25 00:01:35,480 --> 00:01:38,760 Speaker 1: global emissions, and its share is expected to rise in 26 00:01:38,800 --> 00:01:43,640 Speaker 1: coming decades, so solutions are badly needed. Henry is showing 27 00:01:43,640 --> 00:01:46,640 Speaker 1: me around a dimly lit room bathed in orange light. 28 00:01:47,240 --> 00:01:50,480 Speaker 1: This is the lab microtower uses to three D print 29 00:01:50,600 --> 00:01:54,000 Speaker 1: this film. Henry says the film can reduce fuel consumption 30 00:01:54,040 --> 00:01:57,280 Speaker 1: on planes by four percent. Now that might not sound 31 00:01:57,320 --> 00:01:59,240 Speaker 1: like much, but if the film can be rolled out 32 00:01:59,280 --> 00:02:02,920 Speaker 1: across every lane worldwide, the fuel savings and the emission 33 00:02:02,920 --> 00:02:04,360 Speaker 1: savings would be huge. 34 00:02:04,880 --> 00:02:07,160 Speaker 2: So in five to ten years time, we'll will be 35 00:02:07,200 --> 00:02:09,680 Speaker 2: flying on planes with our Sharkskin on them. But then 36 00:02:09,720 --> 00:02:12,240 Speaker 2: we'll also be having them in the water in marine applications. 37 00:02:12,720 --> 00:02:15,320 Speaker 2: We're replicating the patterns that we find in nature, and 38 00:02:15,440 --> 00:02:18,280 Speaker 2: sharks are step one and a big problem for us 39 00:02:18,280 --> 00:02:20,480 Speaker 2: to solve with big impact. But there's a whole host 40 00:02:20,480 --> 00:02:22,120 Speaker 2: of really interesting materials. 41 00:02:23,240 --> 00:02:26,360 Speaker 1: On today's episode of Zero, we hear from two startups 42 00:02:26,400 --> 00:02:29,320 Speaker 1: I met in Australia. The companies are trying to solve 43 00:02:29,520 --> 00:02:34,040 Speaker 1: very different problems, but both want to clean up existing industries. First, 44 00:02:34,120 --> 00:02:37,160 Speaker 1: we'll hear from Henry at Microtower about where he thinks 45 00:02:37,400 --> 00:02:41,080 Speaker 1: Sharkskin fits into the future of air travel, and later 46 00:02:41,120 --> 00:02:45,200 Speaker 1: in the episode we'll meet Stephen Vasaludis, the founder of Novolith, 47 00:02:45,360 --> 00:02:48,480 Speaker 1: a company trying to introduce a lower carbon form of 48 00:02:48,560 --> 00:03:05,280 Speaker 1: extracting lithium for batteries. Micro Tawer was founded in twenty sixteen. 49 00:03:05,480 --> 00:03:08,600 Speaker 1: It raised five point six million Australian dollars in a 50 00:03:08,680 --> 00:03:12,560 Speaker 1: round led by the country's Clean Energy Finance Corporation. Then 51 00:03:12,720 --> 00:03:15,800 Speaker 1: it got a three million dollar grant from the Australian government, 52 00:03:16,000 --> 00:03:18,720 Speaker 1: which will go to fund trials with the country's low 53 00:03:18,760 --> 00:03:23,360 Speaker 1: cost airline, Jetstar. I joined the startup CEO, Henry Bolinski, 54 00:03:23,560 --> 00:03:26,720 Speaker 1: at the company's office in the outskirts of Sydney earlier 55 00:03:26,720 --> 00:03:29,880 Speaker 1: this year. I also talked to Ian Leerman, the head 56 00:03:29,919 --> 00:03:32,720 Speaker 1: of the Clean Energy Finance Corporation, in a past episode 57 00:03:32,760 --> 00:03:35,280 Speaker 1: of the podcast. The link is in the show notes 58 00:03:35,320 --> 00:03:40,480 Speaker 1: if you want to hear more. Henry, Welcome to the show. 59 00:03:40,640 --> 00:03:42,480 Speaker 2: Thank you, good to be here now. 60 00:03:42,480 --> 00:03:45,560 Speaker 1: We're going to talk about sharkskin being used for good 61 00:03:45,560 --> 00:03:48,440 Speaker 1: things Before we do that, how did you come to 62 00:03:49,080 --> 00:03:52,120 Speaker 1: working on sharkskin applications for stuff? 63 00:03:52,360 --> 00:03:54,480 Speaker 2: It was an unusual way to get involved. It came 64 00:03:54,520 --> 00:03:57,840 Speaker 2: about from a global innovation challenge that the US Air 65 00:03:57,880 --> 00:04:01,160 Speaker 2: Force Research Laboratory posted. It was actually late twenty fifteen 66 00:04:01,200 --> 00:04:03,040 Speaker 2: that they posted this challenge, and they were looking for 67 00:04:03,120 --> 00:04:06,160 Speaker 2: ways to reduce their eight billion dollar a year fuel burn. 68 00:04:06,320 --> 00:04:08,680 Speaker 2: And the line's share of that came from their transport aircraft, 69 00:04:08,800 --> 00:04:12,520 Speaker 2: so big heavy planes, things like C seventeen one thirties. 70 00:04:12,760 --> 00:04:15,680 Speaker 1: Well, the Department of Defense in the US is probably 71 00:04:15,680 --> 00:04:18,080 Speaker 1: one of the largest, if not the largest, emitter of 72 00:04:18,080 --> 00:04:18,960 Speaker 1: greeno's gases. 73 00:04:19,240 --> 00:04:23,960 Speaker 2: Yep, so I know the Air Force alone spends about 74 00:04:24,000 --> 00:04:26,760 Speaker 2: ten billion dollars a year on fuel now, and so yeah, 75 00:04:26,760 --> 00:04:28,960 Speaker 2: we've got we've got planes flying overhead to demonstrate it 76 00:04:29,120 --> 00:04:31,880 Speaker 2: just for this podcast. We organize it. Oh no, we're 77 00:04:31,960 --> 00:04:33,840 Speaker 2: under the flightpath here in Sydney. But it's a it's 78 00:04:33,839 --> 00:04:37,360 Speaker 2: a nice constant reminder of what we're focusing on. And 79 00:04:37,440 --> 00:04:39,760 Speaker 2: so ten billion dollar a year in fuel, you're talking 80 00:04:39,800 --> 00:04:42,480 Speaker 2: on the order of tens of mega tons of carbon 81 00:04:42,640 --> 00:04:44,960 Speaker 2: being emitted, So at that time they were really just 82 00:04:44,960 --> 00:04:47,719 Speaker 2: focused on reducing their fuel burn in terms of saving 83 00:04:47,760 --> 00:04:50,200 Speaker 2: money and also a national security issue because you know 84 00:04:50,200 --> 00:04:52,880 Speaker 2: they're dependent on being able to burn that. So there 85 00:04:52,920 --> 00:04:55,040 Speaker 2: was a global challenge. I responded to it. 86 00:04:55,160 --> 00:04:55,839 Speaker 1: Is it a researcher. 87 00:04:56,320 --> 00:04:58,200 Speaker 2: No, I was actually getting admitted as a lawyer at 88 00:04:58,240 --> 00:05:00,599 Speaker 2: the time, but I do have a physics background, and 89 00:05:00,680 --> 00:05:02,520 Speaker 2: so I was looking at these kind of online open 90 00:05:02,520 --> 00:05:05,760 Speaker 2: innovation challenges. The thing I was interested in is whether 91 00:05:05,800 --> 00:05:09,280 Speaker 2: you could find new problems to solve with old technologies, 92 00:05:09,680 --> 00:05:11,760 Speaker 2: especially by looking to outside industries. So I tried a 93 00:05:11,839 --> 00:05:13,960 Speaker 2: number of these open innovation challenges, and this air Force 94 00:05:13,960 --> 00:05:16,559 Speaker 2: one came out. They knew about this idea of shark 95 00:05:16,640 --> 00:05:19,320 Speaker 2: skin and that the microscopic patterns that you find on 96 00:05:19,400 --> 00:05:23,680 Speaker 2: shark skin have the effect of reducing drag, and these 97 00:05:23,680 --> 00:05:25,760 Speaker 2: microopak patterns reduced drag, but they didn't really know how 98 00:05:25,839 --> 00:05:28,400 Speaker 2: to practically implement them on a huge service area like 99 00:05:28,400 --> 00:05:31,320 Speaker 2: an aircraft, And so I proposed kind of modifying a 100 00:05:31,320 --> 00:05:34,000 Speaker 2: computer chip manufacturing method called pholotography. It's a way of 101 00:05:34,080 --> 00:05:37,400 Speaker 2: printing things that are even smaller than what you need 102 00:05:37,400 --> 00:05:40,280 Speaker 2: for sharkskin with light and put that in and frankly 103 00:05:40,320 --> 00:05:42,880 Speaker 2: didn't expect to hear anything back, but was selected as 104 00:05:42,880 --> 00:05:44,520 Speaker 2: one of ten awards from around the world and went 105 00:05:44,560 --> 00:05:47,160 Speaker 2: and pitched at an air Force base in Daton, Ohio 106 00:05:47,200 --> 00:05:48,960 Speaker 2: where the right brothers are from the right Perdison Air 107 00:05:49,000 --> 00:05:52,400 Speaker 2: Force Base. There was a whole process, but ultimately one 108 00:05:52,440 --> 00:05:55,960 Speaker 2: a contract to build and develop and demonstrate this technology, 109 00:05:56,040 --> 00:05:58,279 Speaker 2: and that's when I founded the company in twenty sixteen. 110 00:05:58,560 --> 00:06:02,599 Speaker 1: So sharkskin looked pretty smooth. I've not touched a shark, 111 00:06:02,680 --> 00:06:07,200 Speaker 1: but I'm assuming it's very small the changes that you 112 00:06:07,520 --> 00:06:08,640 Speaker 1: are trying to replicate. 113 00:06:09,160 --> 00:06:12,039 Speaker 2: You're right, So they do look smooth, and sharks are 114 00:06:12,120 --> 00:06:15,279 Speaker 2: very efficient swimmers, and you would usually think that a 115 00:06:15,320 --> 00:06:18,520 Speaker 2: smooth surface is the best way to move through air 116 00:06:18,600 --> 00:06:21,719 Speaker 2: or water. What they're covered in, though, is if you 117 00:06:21,720 --> 00:06:23,680 Speaker 2: do touch them, they feel more like sampaper because they're 118 00:06:23,680 --> 00:06:26,279 Speaker 2: these microscopic ridges on the skin of the shark. 119 00:06:26,480 --> 00:06:26,720 Speaker 1: Right. 120 00:06:26,760 --> 00:06:29,719 Speaker 2: Those ridges are known as riblets, so they know sharks 121 00:06:29,800 --> 00:06:32,120 Speaker 2: have developed them of millions of years with the beneficiaries 122 00:06:32,160 --> 00:06:35,279 Speaker 2: of that great R and D. But the first work 123 00:06:35,640 --> 00:06:37,600 Speaker 2: sort of humans looking at this has happened a while 124 00:06:37,600 --> 00:06:40,799 Speaker 2: Agore originally done by NASA about replicating these microscopic patterns. 125 00:06:40,839 --> 00:06:43,680 Speaker 1: So you're just you're kind of piggybacking off NASA's on 126 00:06:43,920 --> 00:06:47,080 Speaker 1: science or US governments on science work, but actually showing 127 00:06:47,080 --> 00:06:48,720 Speaker 1: them how to build it and apply it. 128 00:06:48,839 --> 00:06:51,080 Speaker 2: Yeah. So so NASA did that original work. So they 129 00:06:51,120 --> 00:06:53,159 Speaker 2: made them on the sort of a millimeter scale that 130 00:06:53,240 --> 00:06:55,480 Speaker 2: knew that you need to them down to the micrometer scale, 131 00:06:55,520 --> 00:06:57,280 Speaker 2: so fractions of the width of a human hair is 132 00:06:57,279 --> 00:06:59,320 Speaker 2: what we're talking about to get it to work in aviation. 133 00:06:59,560 --> 00:07:01,960 Speaker 2: So yeah, definitely the beneficiaries of not just NASSA, but 134 00:07:02,000 --> 00:07:03,679 Speaker 2: a whole lot of work has been done the intervening 135 00:07:03,760 --> 00:07:06,719 Speaker 2: years throughout academia and different research institutions. 136 00:07:06,880 --> 00:07:11,080 Speaker 1: And so you propose this idea of making this stuff 137 00:07:11,120 --> 00:07:13,400 Speaker 1: although you didn't have any equipment, you had never done 138 00:07:13,440 --> 00:07:13,840 Speaker 1: it before. 139 00:07:14,000 --> 00:07:16,720 Speaker 2: No, I was Henry from Sydney, and I am very 140 00:07:16,760 --> 00:07:20,520 Speaker 2: lucky that the US government but also the entire advisory 141 00:07:20,520 --> 00:07:23,880 Speaker 2: committee there took a punt on myself and also the 142 00:07:23,920 --> 00:07:26,640 Speaker 2: team that I pulled together. So yeah, I definitely am 143 00:07:26,680 --> 00:07:28,400 Speaker 2: lucky to work with very smart people on this too. 144 00:07:28,560 --> 00:07:33,200 Speaker 1: And so now six seven years on, you are making stuff, yes, 145 00:07:33,280 --> 00:07:36,160 Speaker 1: and we've got a tour of your facility and there 146 00:07:36,200 --> 00:07:39,320 Speaker 1: is light printing happening. But just walk us through you 147 00:07:39,520 --> 00:07:43,360 Speaker 1: briefly the steps involved in making this stuff, and then 148 00:07:43,520 --> 00:07:46,640 Speaker 1: what happens once you do make these films? Right, they're 149 00:07:46,680 --> 00:07:49,160 Speaker 1: basically plastic sheets. 150 00:07:49,280 --> 00:07:51,920 Speaker 2: Yeah, so we're essentially it's a pre fabricated film that 151 00:07:51,960 --> 00:07:54,080 Speaker 2: you stick on to the outside of a plane, very 152 00:07:54,080 --> 00:07:56,360 Speaker 2: similar to other films that are already applied to planes 153 00:07:56,400 --> 00:07:59,320 Speaker 2: that are usually done for advertising or graphical purposes. So 154 00:07:59,360 --> 00:08:01,120 Speaker 2: the way that we may factor and that kind of 155 00:08:01,200 --> 00:08:04,920 Speaker 2: is our core IP and differentiator, is this process we 156 00:08:05,000 --> 00:08:10,280 Speaker 2: call direct contactless microfabrication or DCM. That's basically this process 157 00:08:10,320 --> 00:08:13,160 Speaker 2: where we grow the structures, these microscopic patterns. So again, 158 00:08:13,200 --> 00:08:15,840 Speaker 2: these ridges space about half the width of human hair. 159 00:08:16,240 --> 00:08:19,000 Speaker 2: We grow them with lights, so we get a material 160 00:08:19,440 --> 00:08:22,160 Speaker 2: that cures when it's hit by a ultraviolet light. We 161 00:08:22,280 --> 00:08:24,720 Speaker 2: lay down a layer of this material. It will remain 162 00:08:24,800 --> 00:08:27,280 Speaker 2: liquid or uncured until it's exposed, and then we have 163 00:08:27,280 --> 00:08:30,000 Speaker 2: an optical system that projects that sharkskin patent into the 164 00:08:30,040 --> 00:08:33,000 Speaker 2: surface and grows the structures from the bottom up. The 165 00:08:33,040 --> 00:08:35,880 Speaker 2: reason why I'm being particular on that point is what's 166 00:08:35,920 --> 00:08:38,280 Speaker 2: distinct from typical three D printing is three D printing 167 00:08:38,320 --> 00:08:41,360 Speaker 2: is usually really two D printing done over and over again. 168 00:08:41,400 --> 00:08:42,679 Speaker 2: You print a layer in two D and then you 169 00:08:42,720 --> 00:08:45,839 Speaker 2: do it so on and so forth. We actually can 170 00:08:45,880 --> 00:08:48,400 Speaker 2: print entire three D structures only at the microscale in 171 00:08:48,440 --> 00:08:51,720 Speaker 2: a single exposure step through this process in this effect. 172 00:08:51,760 --> 00:08:56,240 Speaker 1: So explain drag and how exactly this thing reduces drag. 173 00:08:56,559 --> 00:08:59,439 Speaker 2: So drag is the force that a body moving through 174 00:08:59,480 --> 00:09:02,960 Speaker 2: a fluid experiences. So a shark has to expend energy 175 00:09:03,040 --> 00:09:05,120 Speaker 2: to push through the water, or a plane has to 176 00:09:05,160 --> 00:09:07,720 Speaker 2: burn fuel to push through the air. If you can 177 00:09:07,760 --> 00:09:09,719 Speaker 2: reduce that drag, you can reduce amount of energy that 178 00:09:09,760 --> 00:09:12,120 Speaker 2: you have to burn. The way that these structures work, 179 00:09:12,120 --> 00:09:14,560 Speaker 2: it's counterintuitive. Usually a smoother surface is better when it 180 00:09:14,600 --> 00:09:18,600 Speaker 2: comes to reducing drag. But what sharks have worked out 181 00:09:18,640 --> 00:09:22,560 Speaker 2: is if you have these specific ridge designs, you can 182 00:09:22,600 --> 00:09:26,880 Speaker 2: interact with a phenomenon that's known as hepinvortices. So if 183 00:09:26,880 --> 00:09:30,000 Speaker 2: you zoom down to that microscopic scale in what's called 184 00:09:30,000 --> 00:09:32,680 Speaker 2: turbulent flow, so when the flow is all messy, which 185 00:09:32,720 --> 00:09:36,000 Speaker 2: is most of the flow that anything experiences, especially planes. 186 00:09:35,840 --> 00:09:39,360 Speaker 1: I mean, I think one visual is an incense stick. 187 00:09:39,400 --> 00:09:41,440 Speaker 1: If you burn it in a closed room, you get 188 00:09:41,440 --> 00:09:44,839 Speaker 1: this nice stream. If you move your hand around it 189 00:09:44,840 --> 00:09:47,880 Speaker 1: and it just becomes chaotic, and that's kind of turbulance. 190 00:09:47,520 --> 00:09:50,240 Speaker 2: Right, exactly right. So when it's all nice, clean streams 191 00:09:50,240 --> 00:09:52,760 Speaker 2: of smoke, you can see, that's lamina flow, where everything's 192 00:09:52,840 --> 00:09:55,559 Speaker 2: ordered and predictable. And then eventually, if you wait long enough, 193 00:09:55,600 --> 00:09:57,560 Speaker 2: the top of that will get all messy and swell around, 194 00:09:57,559 --> 00:10:01,160 Speaker 2: and that's turbulent flow. Now, on a plane or on 195 00:10:01,160 --> 00:10:03,720 Speaker 2: a shark, most of the flow is turbulent flow. And 196 00:10:03,760 --> 00:10:05,880 Speaker 2: if you zoom in small enough, there are these very 197 00:10:05,920 --> 00:10:09,040 Speaker 2: predictable structures called hairpin vortices. They're kind of in the 198 00:10:09,040 --> 00:10:11,800 Speaker 2: shape of a hairpin, funnily enough, through about the diameter 199 00:10:11,840 --> 00:10:14,840 Speaker 2: of a human hair. They're very predictable according to your 200 00:10:14,840 --> 00:10:17,679 Speaker 2: flow conditions, and they provide additional scrubbing and energy on 201 00:10:17,720 --> 00:10:20,360 Speaker 2: that surface, which essentially means more friction drag, more drag 202 00:10:20,400 --> 00:10:23,000 Speaker 2: that's applying to the surface that's moving through the fluid. 203 00:10:23,960 --> 00:10:26,520 Speaker 2: But if you can make these ridges just narrower than 204 00:10:26,559 --> 00:10:29,920 Speaker 2: the diameter of that vortex, then you can actually exclude 205 00:10:29,920 --> 00:10:31,720 Speaker 2: it from the surface and it doesn't fit in between 206 00:10:31,720 --> 00:10:34,320 Speaker 2: the ridges. And only interacts with these very sharp peaks. 207 00:10:34,960 --> 00:10:36,600 Speaker 2: The result of that is that you get a net 208 00:10:36,679 --> 00:10:39,080 Speaker 2: drag reduction effect because they're not actually interacting with the 209 00:10:39,080 --> 00:10:42,480 Speaker 2: surface completely. Again, sharks get the credit for coming up 210 00:10:42,480 --> 00:10:45,200 Speaker 2: with this idea, and it works incredibly well. So with 211 00:10:45,280 --> 00:10:47,240 Speaker 2: the material that we have made to date and sort 212 00:10:47,240 --> 00:10:50,000 Speaker 2: of our our current generation of product, we reliably get 213 00:10:50,000 --> 00:10:53,880 Speaker 2: an eight percent friction drag saving. That'll have a different 214 00:10:53,920 --> 00:10:56,120 Speaker 2: impact depending on the application, but on a typical tube 215 00:10:56,120 --> 00:10:58,920 Speaker 2: and we're getting aircraft, you've got half of your drag 216 00:10:58,960 --> 00:11:01,520 Speaker 2: being friction drag, so that eight percent becomes a four 217 00:11:01,520 --> 00:11:04,400 Speaker 2: percent net efficiency gain, So four percent less fuel burned, 218 00:11:04,520 --> 00:11:06,080 Speaker 2: four percent less carbon emissions. 219 00:11:06,280 --> 00:11:08,719 Speaker 1: Well, you give sharks credit. It's not like they were 220 00:11:08,760 --> 00:11:11,720 Speaker 1: thinking about it. It's just that they kept swimming in 221 00:11:11,760 --> 00:11:14,800 Speaker 1: the water and the more efficient ones one out and 222 00:11:14,880 --> 00:11:17,600 Speaker 1: then they got evolved into the beast that they are 223 00:11:17,960 --> 00:11:18,960 Speaker 1: beautiful as they are. 224 00:11:19,120 --> 00:11:21,040 Speaker 2: I can't claim to know the inner workings of shouts, 225 00:11:21,080 --> 00:11:22,760 Speaker 2: but they definitely are the ones that came up with it. 226 00:11:22,840 --> 00:11:24,040 Speaker 2: So whether they thought of it or. 227 00:11:23,960 --> 00:11:26,560 Speaker 1: Not, so what kind of impact do you think you 228 00:11:26,600 --> 00:11:26,960 Speaker 1: can have? 229 00:11:27,800 --> 00:11:31,480 Speaker 2: So today global aviation spends about turning to billion dollars 230 00:11:31,520 --> 00:11:33,840 Speaker 2: on fuel, producing about a billion tons of carbon, and 231 00:11:33,920 --> 00:11:36,000 Speaker 2: we could be with our current products saving up to 232 00:11:36,120 --> 00:11:39,720 Speaker 2: about four percent of that. On individual, say wide body aircraft, 233 00:11:40,080 --> 00:11:41,559 Speaker 2: we can be saving on the order of a million 234 00:11:41,559 --> 00:11:46,280 Speaker 2: dollars of fuel a year and three thousand tons of carbon. 235 00:11:46,480 --> 00:11:48,120 Speaker 2: And that's where we're currently at. And the other thing, 236 00:11:48,200 --> 00:11:50,120 Speaker 2: which which I referred to when I showed you the 237 00:11:50,640 --> 00:11:52,800 Speaker 2: lab and the tour, we really want to leverage the 238 00:11:52,800 --> 00:11:55,080 Speaker 2: fact that we can make new designs and improve those savings. 239 00:11:55,600 --> 00:11:58,120 Speaker 2: And we also work with the University of Melbourne. They'll 240 00:11:58,120 --> 00:12:00,560 Speaker 2: be building us a dedicated testing facility so we can 241 00:12:00,600 --> 00:12:03,600 Speaker 2: start rapidly iterating the different designs that we can make, 242 00:12:04,120 --> 00:12:07,040 Speaker 2: test them in the testing facility and improve that performance. 243 00:12:07,080 --> 00:12:10,040 Speaker 2: And we're nowhere near any sort of physical limit as 244 00:12:10,040 --> 00:12:12,520 Speaker 2: to what kind of efficiency gains we can be getting 245 00:12:12,559 --> 00:12:15,920 Speaker 2: when it comes to functional surfaces and how we can 246 00:12:16,000 --> 00:12:18,680 Speaker 2: improve the efficiency of aviation. So we want to push 247 00:12:18,679 --> 00:12:19,840 Speaker 2: that up closer to ten percent. 248 00:12:20,080 --> 00:12:23,880 Speaker 1: And what will be required to pass what would be 249 00:12:23,920 --> 00:12:26,120 Speaker 1: a pretty strict regulatory environment. 250 00:12:26,679 --> 00:12:29,679 Speaker 2: Yes, so you're right. Aviation is a highly regulated industry, 251 00:12:29,840 --> 00:12:32,959 Speaker 2: which is great. That's why we're safely flying on planes 252 00:12:33,000 --> 00:12:34,560 Speaker 2: and not worrying about them falling out of the sky, 253 00:12:35,240 --> 00:12:36,839 Speaker 2: and so we need to make sure that we fit 254 00:12:36,880 --> 00:12:40,120 Speaker 2: within that regulatory process. We have a great model for 255 00:12:40,200 --> 00:12:43,240 Speaker 2: how we can get onto aircraft, which is the graphical 256 00:12:43,280 --> 00:12:46,920 Speaker 2: films are referred to earlier, so they're already films that 257 00:12:47,000 --> 00:12:49,280 Speaker 2: are up to spec and applied to aircraft and flown 258 00:12:49,280 --> 00:12:52,760 Speaker 2: on aircraft regularly. So we're installing in the same procedures, 259 00:12:52,800 --> 00:12:54,920 Speaker 2: the same way, the same kinds of materials and passing 260 00:12:54,920 --> 00:12:58,680 Speaker 2: those material specs and that's the method that we're using 261 00:12:58,720 --> 00:13:01,920 Speaker 2: for we've got some upcoming flight trials, so we just 262 00:13:01,960 --> 00:13:04,280 Speaker 2: had a project announced with some funding from the Australian 263 00:13:04,320 --> 00:13:07,840 Speaker 2: through government, which is in partnership with Jetstar, which is 264 00:13:07,880 --> 00:13:10,840 Speaker 2: our biggest low cost carrier here in Australia, and so 265 00:13:11,240 --> 00:13:14,200 Speaker 2: we're taking that approach by using their existing framework of 266 00:13:14,200 --> 00:13:16,480 Speaker 2: how they get films on and that's great for the 267 00:13:16,480 --> 00:13:19,960 Speaker 2: purpose of flight trials and initial applications. When it comes 268 00:13:20,040 --> 00:13:22,880 Speaker 2: to launching this and putting this on many aircraft and 269 00:13:22,920 --> 00:13:25,120 Speaker 2: really having the impact that we want to have, we'll 270 00:13:25,120 --> 00:13:27,800 Speaker 2: be getting what's called a supplemental type certificate, which is 271 00:13:27,800 --> 00:13:30,439 Speaker 2: an approved change to an existing aircraft. 272 00:13:30,360 --> 00:13:32,840 Speaker 1: And these films which they put on for advertising, etc. 273 00:13:33,160 --> 00:13:35,280 Speaker 1: They take them off after a year or two. If 274 00:13:35,360 --> 00:13:37,800 Speaker 1: that you're going to have to keep them on planes 275 00:13:37,840 --> 00:13:39,359 Speaker 1: which last ten to twenty. 276 00:13:39,160 --> 00:13:42,240 Speaker 2: Years, Yes and no, you're correct. The graphical films are 277 00:13:42,280 --> 00:13:44,319 Speaker 2: typically removed within say a year or so, but there 278 00:13:44,320 --> 00:13:46,640 Speaker 2: are products out there that have flown for over eight years, 279 00:13:46,760 --> 00:13:48,440 Speaker 2: so there is precedent in terms of having them on 280 00:13:48,480 --> 00:13:50,600 Speaker 2: for longer. That's about the period of time that we 281 00:13:50,640 --> 00:13:52,800 Speaker 2: want our product to last. And the reason we're not 282 00:13:52,800 --> 00:13:56,480 Speaker 2: looking at longer than that is there are very well 283 00:13:56,520 --> 00:13:59,559 Speaker 2: defined maintenance checks that are done on aircraft for the 284 00:13:59,600 --> 00:14:02,000 Speaker 2: same reason and of keeping them safe. And you'll have 285 00:14:02,040 --> 00:14:04,840 Speaker 2: a heavy maintenance check, which depending on the aircraft and 286 00:14:04,840 --> 00:14:07,800 Speaker 2: how it's operated, could be every five to ten years, 287 00:14:08,440 --> 00:14:11,440 Speaker 2: and that's where all of the paint will be stripped 288 00:14:11,440 --> 00:14:13,480 Speaker 2: off the plane and will be checked down to the 289 00:14:13,520 --> 00:14:15,800 Speaker 2: core structure of the plane and then it will be repainted. 290 00:14:16,040 --> 00:14:18,400 Speaker 2: So lasting any longer than that is not really relevant 291 00:14:18,400 --> 00:14:20,440 Speaker 2: for our product, but you're right, we definitely want to 292 00:14:20,440 --> 00:14:22,560 Speaker 2: make sure that we're lasting that period of time. The 293 00:14:22,600 --> 00:14:25,440 Speaker 2: business case is still very much attractive even if it 294 00:14:25,480 --> 00:14:27,560 Speaker 2: was only a two year product. But we're looking to 295 00:14:27,560 --> 00:14:29,360 Speaker 2: make that last as long as possible again to have 296 00:14:29,440 --> 00:14:29,960 Speaker 2: that impact. 297 00:14:30,240 --> 00:14:32,840 Speaker 1: And on the dour we saw the lab and the 298 00:14:32,880 --> 00:14:36,040 Speaker 1: testing facility. It's relatively small for what you need to 299 00:14:36,040 --> 00:14:38,680 Speaker 1: do now, but where are you going to manufacture at 300 00:14:38,720 --> 00:14:41,240 Speaker 1: scale if you're going to cover entire planes with this material? 301 00:14:41,440 --> 00:14:44,040 Speaker 2: Yes, so the facility that you saw here today that 302 00:14:44,120 --> 00:14:46,600 Speaker 2: core technology. We talked about the way that we manufacture 303 00:14:46,760 --> 00:14:49,640 Speaker 2: and essentially what we develop here are the materials and 304 00:14:49,760 --> 00:14:53,640 Speaker 2: kind of the key manufacturing inputs to manufacture large amounts 305 00:14:53,640 --> 00:14:57,080 Speaker 2: of product at scale. Those inputs go to a continuous 306 00:14:57,320 --> 00:15:00,120 Speaker 2: role for roll manufacturing process and we currently work with 307 00:15:00,120 --> 00:15:03,040 Speaker 2: different third party manufacturers where we go and have access 308 00:15:03,040 --> 00:15:05,600 Speaker 2: to their existing production lines. We're about to know the 309 00:15:05,600 --> 00:15:08,360 Speaker 2: production run on the order of say a commu's worth material, 310 00:15:08,400 --> 00:15:10,120 Speaker 2: which is plenty for us to do a couple of 311 00:15:10,160 --> 00:15:12,800 Speaker 2: flight trials. And then when it comes to scaling up 312 00:15:12,920 --> 00:15:16,800 Speaker 2: that manufacturing first, our first manufacturing scale facility will be 313 00:15:16,800 --> 00:15:20,880 Speaker 2: here in Australia. But the volumes that we're talking about 314 00:15:21,080 --> 00:15:24,720 Speaker 2: we expect to be building these in locations in the 315 00:15:24,720 --> 00:15:27,280 Speaker 2: geography is where close to the markets that we need 316 00:15:27,280 --> 00:15:29,440 Speaker 2: to ultimately serve. So so we'll have something in Europe, 317 00:15:29,480 --> 00:15:31,040 Speaker 2: something in the US. Is how we'll do this in 318 00:15:31,040 --> 00:15:31,680 Speaker 2: the long term. 319 00:15:31,840 --> 00:15:35,800 Speaker 1: The applications, though, don't have to be just restricted to aplanes. 320 00:15:36,200 --> 00:15:39,360 Speaker 1: Drag is a problem for all sorts of things, anything 321 00:15:39,360 --> 00:15:43,560 Speaker 1: that moves really, whether it's in water or on the road. 322 00:15:43,960 --> 00:15:46,320 Speaker 2: Yeah, that's exactly right. Obviously, we're focused on aviation at 323 00:15:46,320 --> 00:15:48,840 Speaker 2: the moment, and there is a reason for that. Aviation 324 00:15:48,920 --> 00:15:52,200 Speaker 2: is very hard to abate industry. There's a trillion dollars 325 00:15:52,240 --> 00:15:54,520 Speaker 2: of planes flying today which aren't going to be thrown 326 00:15:54,560 --> 00:15:57,240 Speaker 2: away anytime soon, earning about two hundred million dollars worth 327 00:15:57,240 --> 00:15:59,520 Speaker 2: of fuel and producing about a billion tons of carbon. 328 00:16:00,080 --> 00:16:01,760 Speaker 2: So we're getting very clear signals that this is a 329 00:16:01,760 --> 00:16:04,520 Speaker 2: problem that the market wants us to solve first. But 330 00:16:04,680 --> 00:16:07,280 Speaker 2: we're also looking at other applications further down the line, 331 00:16:07,440 --> 00:16:10,400 Speaker 2: so we can be applying this to ships, say cargo ships, 332 00:16:10,760 --> 00:16:13,200 Speaker 2: to improve their efficiency as well. I had a couple 333 00:16:13,160 --> 00:16:15,680 Speaker 2: of other things, yes, because I listened to your episode 334 00:16:15,880 --> 00:16:18,560 Speaker 2: about flying cars. I listened to that and I was like, oh, 335 00:16:18,600 --> 00:16:20,920 Speaker 2: that's probably why you want to talk to us, because 336 00:16:21,040 --> 00:16:25,560 Speaker 2: you're skeptical about the transition of aviation to electric Exactly 337 00:16:25,760 --> 00:16:27,240 Speaker 2: and I think that's a big part of what we're 338 00:16:27,240 --> 00:16:29,760 Speaker 2: trying to solve, something which I think is why we're 339 00:16:29,800 --> 00:16:33,000 Speaker 2: getting a lot of traction in aviation. The entire industry 340 00:16:33,040 --> 00:16:36,240 Speaker 2: is committed to net zero by twenty fifty, and there 341 00:16:36,320 --> 00:16:38,280 Speaker 2: is not a clear easy shot to get there. 342 00:16:38,400 --> 00:16:40,880 Speaker 1: Yeah. I mean that's true for many industries, but particularly 343 00:16:40,960 --> 00:16:42,040 Speaker 1: true for our aviation. 344 00:16:42,240 --> 00:16:44,800 Speaker 2: Yes, and even your colleague you were talking to said 345 00:16:45,280 --> 00:16:49,720 Speaker 2: he's bullish on electric aviation and hydroen aviation and best 346 00:16:49,720 --> 00:16:52,600 Speaker 2: case scenario that solves short and medium whole flight, there 347 00:16:52,640 --> 00:16:54,240 Speaker 2: is no way that it's going to be doing wide 348 00:16:54,240 --> 00:16:55,720 Speaker 2: body along whul flights. But the other thing, and the 349 00:16:55,720 --> 00:16:57,280 Speaker 2: reason why I made reference to the fact there's about 350 00:16:57,280 --> 00:17:00,000 Speaker 2: a trillion dollars worth of planes burning fuel and operation today, 351 00:17:00,120 --> 00:17:02,600 Speaker 2: not to mention all the planes that are being manufactured 352 00:17:03,000 --> 00:17:06,160 Speaker 2: still to be burning fuel, is we need to think 353 00:17:06,200 --> 00:17:08,200 Speaker 2: about something which has an impact in the next five 354 00:17:08,200 --> 00:17:10,879 Speaker 2: to ten years. We can't just sort of hold on 355 00:17:11,080 --> 00:17:14,560 Speaker 2: for a new breakthrough in battery or hydrogen technology. I 356 00:17:14,560 --> 00:17:16,560 Speaker 2: think it's very necessary and very excited for those things 357 00:17:16,600 --> 00:17:20,359 Speaker 2: to come online, but it's an even longer regulatory road 358 00:17:20,400 --> 00:17:21,840 Speaker 2: to get new platforms. 359 00:17:21,359 --> 00:17:24,080 Speaker 1: Off for sure. And even if you do get electric 360 00:17:24,119 --> 00:17:28,919 Speaker 1: and hydrogen planes working, any amount of efficiency gain that 361 00:17:29,000 --> 00:17:33,640 Speaker 1: you get for them, the easier their job becomes because 362 00:17:33,680 --> 00:17:35,560 Speaker 1: then you have to put fewer batteries on, you have 363 00:17:35,600 --> 00:17:39,119 Speaker 1: to put less fuel on. So efficiency is this weapon 364 00:17:39,160 --> 00:17:44,480 Speaker 1: that few people think off or use as effectively as 365 00:17:44,520 --> 00:17:46,440 Speaker 1: you can use to get to net zero. 366 00:17:46,800 --> 00:17:49,119 Speaker 2: Yeah, and so I think where we're coming at this 367 00:17:49,200 --> 00:17:51,119 Speaker 2: is in the near term, we want to have an 368 00:17:51,160 --> 00:17:53,960 Speaker 2: impact on the existing global fleet. You know, every airline's 369 00:17:54,000 --> 00:17:56,240 Speaker 2: committed to say one half percent efficiency gains the plane, 370 00:17:56,280 --> 00:17:58,439 Speaker 2: just buy new planes. We can be a part of 371 00:17:58,440 --> 00:18:00,760 Speaker 2: that solution to not only help them achieve that, but 372 00:18:00,840 --> 00:18:03,040 Speaker 2: save money in the process. You're not paying a grain premium, 373 00:18:03,080 --> 00:18:06,879 Speaker 2: you're saving fuel in the process. But as electric and hydrogen, 374 00:18:07,000 --> 00:18:11,400 Speaker 2: you know, alternative powered aviation comes online, they'll be doing 375 00:18:11,440 --> 00:18:15,160 Speaker 2: really short hops initially, and if maybe an extra five 376 00:18:15,200 --> 00:18:19,680 Speaker 2: percent efficiency unlocks La to San Francisco, there's a huge 377 00:18:19,680 --> 00:18:21,240 Speaker 2: impact there and we really want to be able to 378 00:18:21,280 --> 00:18:24,320 Speaker 2: help with that transition as we have these alternative aviation 379 00:18:24,680 --> 00:18:25,920 Speaker 2: platforms coming online. 380 00:18:26,000 --> 00:18:28,560 Speaker 1: Well, thanks for the tour. Nice to see sharks in 381 00:18:28,600 --> 00:18:31,560 Speaker 1: a better light than a lot of people. 382 00:18:31,320 --> 00:18:33,400 Speaker 2: Think Sharks are great. 383 00:18:33,440 --> 00:18:41,879 Speaker 1: Absolutely. Since recording this interview, Microtower has begun flight trials 384 00:18:41,880 --> 00:18:44,200 Speaker 1: off its technology and plans for it to be rolled 385 00:18:44,200 --> 00:18:47,320 Speaker 1: out more broadly on commercial jets in twenty twenty five 386 00:18:48,280 --> 00:18:51,240 Speaker 1: after the break. To meet net zero, we need enough 387 00:18:51,280 --> 00:18:54,359 Speaker 1: batteries for a billion electric cars and lithium is a 388 00:18:54,400 --> 00:18:57,720 Speaker 1: crucial part of that equation. Is there a cleaner way 389 00:18:57,760 --> 00:19:09,960 Speaker 1: to source it? While I was in Australia, I also 390 00:19:10,000 --> 00:19:13,240 Speaker 1: met up with Stephen vas Ludis, CEO of Novalith, a 391 00:19:13,280 --> 00:19:16,000 Speaker 1: company that wants to reduce the carbon emissions that come 392 00:19:16,040 --> 00:19:20,720 Speaker 1: from extracting lithium. Like Microtao, Novallyith is another company that 393 00:19:20,800 --> 00:19:23,359 Speaker 1: has raised money with the support of the Clean Energy 394 00:19:23,359 --> 00:19:27,359 Speaker 1: Finance Corporation, first two point five million Australian dollars in 395 00:19:27,400 --> 00:19:30,640 Speaker 1: twenty twenty one, and then it completed a twenty three 396 00:19:30,680 --> 00:19:33,480 Speaker 1: million dollar rais. I met Stephen at the Novlith office 397 00:19:33,520 --> 00:19:40,639 Speaker 1: in Sydney. Now we're going to talk about lithium mining 398 00:19:41,080 --> 00:19:44,240 Speaker 1: and what it is that Novalith, your company is doing 399 00:19:44,560 --> 00:19:48,080 Speaker 1: to make it more efficient and even maybe carbon negative, 400 00:19:48,119 --> 00:19:50,960 Speaker 1: which is a bold claim. But before that, how do 401 00:19:51,080 --> 00:19:51,920 Speaker 1: you come to do this? 402 00:19:52,320 --> 00:19:54,360 Speaker 3: So in terms of I guess the origin story. Sam 403 00:19:54,520 --> 00:19:57,359 Speaker 3: chemical engineer by background. I worked in a number of 404 00:19:57,359 --> 00:20:01,440 Speaker 3: industries prior to novelith oil and gas, conventional chemical engineering, 405 00:20:01,480 --> 00:20:03,639 Speaker 3: you know, try to make things cleaner and greener, and 406 00:20:03,680 --> 00:20:05,760 Speaker 3: that's really been the big push for me over the 407 00:20:05,800 --> 00:20:08,600 Speaker 3: last decade or so, and that's what led to the 408 00:20:08,640 --> 00:20:11,600 Speaker 3: genesis of Novel Earth. Looking at the way the world 409 00:20:11,680 --> 00:20:14,399 Speaker 3: is moving, right, we desperately need to electrify. The only 410 00:20:14,440 --> 00:20:16,920 Speaker 3: way for us to do that is by using lithium 411 00:20:16,960 --> 00:20:20,520 Speaker 3: at large scale, and the conventional means of lithium production 412 00:20:20,600 --> 00:20:24,160 Speaker 3: are not particularly quick, clean, or cost effective. 413 00:20:24,240 --> 00:20:26,920 Speaker 1: Well, most people won't know this because most people haven't 414 00:20:26,960 --> 00:20:30,280 Speaker 1: thought about lithium mining. They've thought about lithium's used in 415 00:20:30,320 --> 00:20:32,879 Speaker 1: batteries because everybody has a smartphone and they have lithium 416 00:20:33,000 --> 00:20:33,520 Speaker 1: in batteries. 417 00:20:33,640 --> 00:20:35,120 Speaker 3: And now EV's is a big push as well. 418 00:20:35,200 --> 00:20:38,920 Speaker 1: Right exactly. But let's go from the basics of how 419 00:20:39,280 --> 00:20:40,960 Speaker 1: lithium is mined and processed. 420 00:20:41,080 --> 00:20:42,879 Speaker 3: Yeah, so in terms of lithium, you have kind of 421 00:20:42,920 --> 00:20:45,720 Speaker 3: two main sources of lithium. So you have your contentle brands, 422 00:20:45,880 --> 00:20:50,000 Speaker 3: So the lithium triangle in South America, so that's Argentina, Chiliblivia. 423 00:20:49,520 --> 00:20:52,480 Speaker 1: And that's basically liquids that are found under the Earth, 424 00:20:52,480 --> 00:20:55,720 Speaker 1: which are very highly concentrated in different types of salts, 425 00:20:55,760 --> 00:20:58,760 Speaker 1: including lithium in them. Correct, And so you just pull 426 00:20:58,800 --> 00:21:01,080 Speaker 1: out a lot of liquid, you put it in these 427 00:21:01,119 --> 00:21:04,280 Speaker 1: salt pans, let them dry, take what's left, which is 428 00:21:04,400 --> 00:21:07,560 Speaker 1: usually some type of powder, and then make chemicals out 429 00:21:07,600 --> 00:21:07,880 Speaker 1: of them. 430 00:21:08,040 --> 00:21:10,199 Speaker 3: Exactly. That's very much your Brian's right. They, you know, 431 00:21:10,280 --> 00:21:12,960 Speaker 3: take their lithium chloride powder or slurry ship off to 432 00:21:13,160 --> 00:21:15,919 Speaker 3: China to refine into a lithium chemical. The other way 433 00:21:15,960 --> 00:21:18,480 Speaker 3: of getting lithium is from rock, and so the vast 434 00:21:18,480 --> 00:21:20,880 Speaker 3: majority of kind of rock based lithium, so about sixty 435 00:21:20,880 --> 00:21:23,480 Speaker 3: percent of the world supply comes from Western Australia in 436 00:21:23,520 --> 00:21:26,720 Speaker 3: the form of spodymene, and that's a hard rock. There's 437 00:21:26,760 --> 00:21:29,160 Speaker 3: other sources of lithium so soft rocks, such in North 438 00:21:29,160 --> 00:21:32,000 Speaker 3: America and Europe, but the vast majority at the moment 439 00:21:32,160 --> 00:21:33,760 Speaker 3: is from that hard rock based resource. 440 00:21:33,800 --> 00:21:36,760 Speaker 1: And we've got some SPoD being here that you showed me. 441 00:21:37,200 --> 00:21:39,080 Speaker 1: I mean, I've not been to a lithium mind, but 442 00:21:40,119 --> 00:21:43,600 Speaker 1: the pieces of rock you're showing me are all different colored, 443 00:21:43,680 --> 00:21:46,439 Speaker 1: like there's green and there's white, and there's purple and 444 00:21:46,520 --> 00:21:51,040 Speaker 1: even yellow. I thought mine rocks would look lamer. 445 00:21:51,600 --> 00:21:54,640 Speaker 3: Yeah, look, I think we're actually in a pretty cool 446 00:21:54,680 --> 00:21:57,720 Speaker 3: game with the lithium rocks. Lithium rocks generally all look 447 00:21:57,760 --> 00:21:59,960 Speaker 3: quite pretty, and there's one hundred and one different types 448 00:22:00,040 --> 00:22:02,840 Speaker 3: of kind of lithium bearing ores. They all look pretty cool, 449 00:22:02,880 --> 00:22:04,840 Speaker 3: I mean, except maybe the clays. The clays are I 450 00:22:04,880 --> 00:22:07,280 Speaker 3: guess a bit boring, right, They just look like a clay. 451 00:22:08,400 --> 00:22:12,880 Speaker 1: And so you take either rock or brine, and then 452 00:22:12,880 --> 00:22:13,880 Speaker 1: what do you have to do next? 453 00:22:13,920 --> 00:22:16,880 Speaker 3: So the conventional process is, you know, once you've kind 454 00:22:16,880 --> 00:22:19,440 Speaker 3: of mind it, you've then concentrated to increase the amount 455 00:22:19,440 --> 00:22:21,040 Speaker 3: of lithium from you know, so you're one or two 456 00:22:21,080 --> 00:22:23,480 Speaker 3: percent to say five or six percent. You then ship 457 00:22:23,520 --> 00:22:26,320 Speaker 3: that spodyman concentrate to China, and about you know, eighty 458 00:22:26,320 --> 00:22:28,399 Speaker 3: to ninety ten of the world's lithium is currently refined 459 00:22:28,400 --> 00:22:30,480 Speaker 3: in China or roads lead to China in the lithium 460 00:22:30,520 --> 00:22:32,480 Speaker 3: game at the moment, and I think the world is 461 00:22:32,480 --> 00:22:34,320 Speaker 3: trying to change that, but it'll take a little while 462 00:22:34,520 --> 00:22:36,439 Speaker 3: for that to pick up. But yeah, so once it 463 00:22:36,440 --> 00:22:39,240 Speaker 3: gets to the the lithium refinery, depending on the source 464 00:22:39,240 --> 00:22:42,440 Speaker 3: of lithium. There's a quite a complicated and long winded 465 00:22:42,480 --> 00:22:45,760 Speaker 3: chemical process, but in a nutshell, you heat it up, 466 00:22:45,840 --> 00:22:47,840 Speaker 3: you hit it with a very very strong acid. So 467 00:22:47,920 --> 00:22:51,239 Speaker 3: sulfuric acid, sulfuric acid us A SULFORG generally comes off 468 00:22:51,240 --> 00:22:53,560 Speaker 3: the back of oil and gas, right desulfurization. 469 00:22:53,800 --> 00:22:56,399 Speaker 1: Just so people know, sulfuric acid is one of the 470 00:22:56,440 --> 00:22:57,760 Speaker 1: strongest acids there is. 471 00:22:57,920 --> 00:23:00,200 Speaker 3: Definitely, Yes, it's not something you really want to leave 472 00:23:00,200 --> 00:23:01,879 Speaker 3: out in the kitchen table. And if you're working with it, 473 00:23:01,920 --> 00:23:04,320 Speaker 3: I mean there's a lot of safety considerations that you 474 00:23:04,359 --> 00:23:06,480 Speaker 3: need to take into account. And again that's one of 475 00:23:06,480 --> 00:23:08,320 Speaker 3: the things that we're trying to move away from, is 476 00:23:08,359 --> 00:23:10,560 Speaker 3: in terms of using quite a harmful chemical, not only 477 00:23:10,600 --> 00:23:13,200 Speaker 3: for personnel but also from the environment. 478 00:23:13,320 --> 00:23:17,240 Speaker 1: Yeah, even though lithium mindes are located in places with 479 00:23:17,359 --> 00:23:22,040 Speaker 1: relatively high concentrations, lithium only makes up a small percentage 480 00:23:22,119 --> 00:23:25,160 Speaker 1: of all the material that is dug up. Steve told 481 00:23:25,160 --> 00:23:28,440 Speaker 1: me it's only a few kilograms for every thousand kilograms 482 00:23:28,520 --> 00:23:32,359 Speaker 1: of mind material. So to separate the lithium you want 483 00:23:32,600 --> 00:23:36,760 Speaker 1: from the materials you don't want, miners use sulfuric acid. 484 00:23:37,720 --> 00:23:41,280 Speaker 1: It does the job because it's highly chemically reactive. But 485 00:23:41,480 --> 00:23:44,800 Speaker 1: that also creates a whole bunch of other problems. First, 486 00:23:44,920 --> 00:23:48,320 Speaker 1: it's not selective, which means other metals contained in the 487 00:23:48,400 --> 00:23:53,120 Speaker 1: mind material are also extracted alongside lithium, creating a complex 488 00:23:53,200 --> 00:23:57,840 Speaker 1: chemical soup that you have to further purify. Second, it's toxic, 489 00:23:58,160 --> 00:24:00,880 Speaker 1: so managing it and getting rid of a way safely 490 00:24:01,240 --> 00:24:04,440 Speaker 1: is expensive. Nobile It's idea is to do a way 491 00:24:04,480 --> 00:24:09,080 Speaker 1: with sulfuric acid altogether and use carbonic acid instead, which 492 00:24:09,119 --> 00:24:11,960 Speaker 1: can be made by mixing CO two with water. 493 00:24:13,080 --> 00:24:15,440 Speaker 3: So when you mix CO two in water, you form 494 00:24:15,480 --> 00:24:17,160 Speaker 3: carbonic acid. It's the same thing you're using a soda 495 00:24:17,160 --> 00:24:19,199 Speaker 3: stream at home. Yeah, right, but you don't think of 496 00:24:19,240 --> 00:24:20,919 Speaker 3: it as an acid, right. You can drink it. 497 00:24:21,080 --> 00:24:24,040 Speaker 1: Yeah, but if you drink too much soda, your teeth 498 00:24:24,080 --> 00:24:26,320 Speaker 1: go bad, and that's because it's acidic. 499 00:24:26,720 --> 00:24:29,240 Speaker 3: Correct, correct, So don't drink too much soda as a 500 00:24:29,280 --> 00:24:31,920 Speaker 3: general kind of like health this claim hehet. But yeah, 501 00:24:32,000 --> 00:24:33,919 Speaker 3: you don't worry about the kids playing with it. You 502 00:24:33,960 --> 00:24:35,720 Speaker 3: make it, and it's great to have with a slice 503 00:24:35,760 --> 00:24:38,760 Speaker 3: of lemon. But under the right conditions, we can actually 504 00:24:38,880 --> 00:24:41,480 Speaker 3: use that SEO too. Water mixture very very effectively and 505 00:24:41,520 --> 00:24:45,320 Speaker 3: efficiently to extract lithium from the lithium bearing oles directly 506 00:24:45,359 --> 00:24:47,520 Speaker 3: as a lithium carbonate. And that's kind of like the 507 00:24:47,520 --> 00:24:49,479 Speaker 3: little Noblis black box and our pattern. 508 00:24:50,160 --> 00:24:56,000 Speaker 1: The lithium used inside lithium ion batteries isn't pure lithium. Instead, 509 00:24:56,200 --> 00:25:00,479 Speaker 1: it exists as a salt, either lithium hydroxide or what 510 00:25:00,560 --> 00:25:05,400 Speaker 1: nouvlid makes lithium carbonate. In using carbonic acid to turn 511 00:25:05,600 --> 00:25:09,080 Speaker 1: mind lithium to lithium carbonate, the startup can skip over 512 00:25:09,119 --> 00:25:13,440 Speaker 1: the step where sulfuric acid is normally used. Because carbonic 513 00:25:13,440 --> 00:25:17,360 Speaker 1: acid is a weak acid. It also produces less toxic waste, 514 00:25:18,040 --> 00:25:20,879 Speaker 1: and what waste it does produce is much easier and 515 00:25:21,000 --> 00:25:25,040 Speaker 1: thus cheaper to handle safely. However, to make a weak 516 00:25:25,119 --> 00:25:29,240 Speaker 1: acid work as effectively as a strong acid, nouvlith had 517 00:25:29,240 --> 00:25:34,199 Speaker 1: to design a different process of extraction. So you have 518 00:25:34,280 --> 00:25:37,000 Speaker 1: the black box. Yes that's the IP, but it's patented 519 00:25:37,080 --> 00:25:39,640 Speaker 1: so you can talk about what's public right, what is it? Yees? 520 00:25:39,680 --> 00:25:41,000 Speaker 3: So I mean I feel free to look up for 521 00:25:41,000 --> 00:25:43,760 Speaker 3: those of you who do enjoy digging in patterns. If 522 00:25:43,800 --> 00:25:46,159 Speaker 3: you imagine putting a little bit of spodgyman in a 523 00:25:46,160 --> 00:25:48,159 Speaker 3: glass subside one on the table. Not very much is 524 00:25:48,160 --> 00:25:50,080 Speaker 3: going to happen, right, you will form lithium carbonate. But 525 00:25:50,080 --> 00:25:52,280 Speaker 3: we'll be talking about this inside three is time. And 526 00:25:52,320 --> 00:25:54,840 Speaker 3: so with that process, the way we've managed to do 527 00:25:54,880 --> 00:25:56,239 Speaker 3: this and ast you found that it works really really 528 00:25:56,280 --> 00:25:59,400 Speaker 3: well is by changing temperatures and pressures, and so under 529 00:25:59,400 --> 00:26:02,080 Speaker 3: a very strict set of conditions, we find that we 530 00:26:02,119 --> 00:26:05,399 Speaker 3: can very effectively extract that lithium. And the other thing 531 00:26:05,400 --> 00:26:07,280 Speaker 3: we've looked into is the type of reactors that we're 532 00:26:07,280 --> 00:26:09,720 Speaker 3: looking to use. So going to you know, chemical engineering again, 533 00:26:09,760 --> 00:26:11,879 Speaker 3: there's one hundred and one way to do something. We 534 00:26:11,960 --> 00:26:14,960 Speaker 3: found for our process that a fluidized bed reactor works 535 00:26:14,960 --> 00:26:17,760 Speaker 3: really really well. We can get great extraction efficiencies and 536 00:26:17,800 --> 00:26:20,240 Speaker 3: control that mass transfer, which is what we're. 537 00:26:20,520 --> 00:26:22,879 Speaker 1: As bad reactor, which is a chemical engineer. I know 538 00:26:22,920 --> 00:26:25,080 Speaker 1: what it is, but now that I think about it, 539 00:26:25,080 --> 00:26:27,399 Speaker 1: it's a really interesting name because it sounds like a 540 00:26:27,440 --> 00:26:28,280 Speaker 1: massage table. 541 00:26:28,480 --> 00:26:33,280 Speaker 3: Yeah, yes, well it's to be fun like you can 542 00:26:33,320 --> 00:26:35,040 Speaker 3: kind of imagine it, right, So if you get a 543 00:26:35,080 --> 00:26:37,439 Speaker 3: straw and you kind of blow bubbles at the bottom 544 00:26:37,640 --> 00:26:39,280 Speaker 3: of a glass fall with a bit of sand, right, 545 00:26:39,320 --> 00:26:42,760 Speaker 3: you're effectively making a fluidized bed reactor, and so you 546 00:26:42,760 --> 00:26:44,640 Speaker 3: can see the bubbles kind of passing through the sand 547 00:26:44,760 --> 00:26:46,680 Speaker 3: and it's all kind of jiggling about and doing its thing. 548 00:26:46,720 --> 00:26:48,359 Speaker 3: And that's really what we're doing, just a large. 549 00:26:48,240 --> 00:26:51,880 Speaker 1: Scale massaging the spodamine with lots of acid. 550 00:26:52,119 --> 00:26:54,240 Speaker 3: Yeah, yeah, to get our lithium carbonate. 551 00:26:54,640 --> 00:26:58,080 Speaker 1: But you also made this bold claim saying well we 552 00:26:58,240 --> 00:27:02,320 Speaker 1: can make carbon negative lithium, which you're going to have 553 00:27:02,359 --> 00:27:06,360 Speaker 1: to explain. So a, what is the carbon cost of lithium? 554 00:27:06,680 --> 00:27:09,640 Speaker 1: Why is there a carbon cost to lithium, and how 555 00:27:09,720 --> 00:27:10,960 Speaker 1: is it that you're going to negated? 556 00:27:11,119 --> 00:27:13,040 Speaker 3: Yes, so in terms of that, well, we're currently doing 557 00:27:13,080 --> 00:27:15,040 Speaker 3: able to work on confirming whether we can truly be 558 00:27:15,040 --> 00:27:17,840 Speaker 3: carbon negative. Well, that's definitely our goal. Given that way 559 00:27:17,920 --> 00:27:20,080 Speaker 3: use COO too. You know, there's a really good chance 560 00:27:20,080 --> 00:27:22,680 Speaker 3: of us us achieving that goal. And so in terms 561 00:27:22,720 --> 00:27:25,320 Speaker 3: of I guess the relative carbon intensity, right, if you 562 00:27:25,320 --> 00:27:27,520 Speaker 3: look at the conventional process, you find that the vast 563 00:27:27,520 --> 00:27:29,320 Speaker 3: majority of CO two is emitted in that middle piece, 564 00:27:29,320 --> 00:27:30,480 Speaker 3: so the chemical refining piece. 565 00:27:30,560 --> 00:27:34,120 Speaker 1: Yeah, it's interesting. People would think mining it, which requires 566 00:27:34,119 --> 00:27:37,719 Speaker 1: a lot of energy and moving it then putting it 567 00:27:37,760 --> 00:27:41,680 Speaker 1: either on trains or ships, would be the biggest carbon cost. 568 00:27:41,720 --> 00:27:45,119 Speaker 1: But actually it's the chemicals. It's the treatment of the 569 00:27:45,240 --> 00:27:48,359 Speaker 1: ore that is really the carbon intensive. 570 00:27:48,000 --> 00:27:50,119 Speaker 3: Definitely, and it's the productions of the chemicals. So in 571 00:27:50,160 --> 00:27:52,760 Speaker 3: the production of the softior acid you need for your process, 572 00:27:52,800 --> 00:27:54,880 Speaker 3: you're producing a ton of CO two. And so when 573 00:27:54,880 --> 00:27:57,800 Speaker 3: we compare novelist technology to the conventional, you know, and 574 00:27:57,840 --> 00:28:00,440 Speaker 3: the conventional sitting between say fifteen and two tons of 575 00:28:00,480 --> 00:28:02,560 Speaker 3: CO two putun of lithium chemical and it is jurisdic 576 00:28:02,640 --> 00:28:05,320 Speaker 3: and specific. We were less than half of that, and 577 00:28:05,320 --> 00:28:07,000 Speaker 3: it's already you know, well on the way to being 578 00:28:07,160 --> 00:28:08,479 Speaker 3: carbon neutral, carbon negative. 579 00:28:08,600 --> 00:28:13,639 Speaker 1: Yeah, still ways of the carbon negative. Part of Novolid's 580 00:28:13,680 --> 00:28:17,400 Speaker 1: claim is still just theory. Carbonic acid can be made 581 00:28:17,440 --> 00:28:20,400 Speaker 1: by mixing water with CO two that has been captured 582 00:28:20,520 --> 00:28:24,280 Speaker 1: from the atmosphere. The acid can be combined with waste 583 00:28:24,320 --> 00:28:27,760 Speaker 1: metals from the lithium or to form carbonates that can 584 00:28:27,800 --> 00:28:31,320 Speaker 1: be stored underground, effectively locking the CO two out of 585 00:28:31,320 --> 00:28:35,520 Speaker 1: the atmosphere forever. This is something that is already being 586 00:28:35,560 --> 00:28:39,000 Speaker 1: done by carbon removal companies climb Works and carb Fix 587 00:28:39,280 --> 00:28:43,640 Speaker 1: in Iceland at a small scale. So the theory does work, 588 00:28:44,080 --> 00:28:47,160 Speaker 1: but to make carbon negative lithium novolith will have to 589 00:28:47,200 --> 00:28:50,640 Speaker 1: store away more carbon dioxide than produced by the rest 590 00:28:50,640 --> 00:28:53,640 Speaker 1: of the process. And I'll remain skeptical till I see 591 00:28:53,720 --> 00:28:54,320 Speaker 1: the results. 592 00:28:55,400 --> 00:28:57,160 Speaker 3: So for SPoD, you mean the way we can reduce 593 00:28:57,160 --> 00:29:00,760 Speaker 3: the carbon intensities by using grhinoisols the power grenoil electricity. 594 00:29:00,800 --> 00:29:03,080 Speaker 3: At the moment, everything is coal diesel. I mean it's 595 00:29:03,120 --> 00:29:05,400 Speaker 3: really dirty in terms of the power. Looking forward, we 596 00:29:05,440 --> 00:29:08,600 Speaker 3: can significantly decrease the carbon intensity by using greener sources 597 00:29:08,600 --> 00:29:10,880 Speaker 3: of energy. And then further that if we do have 598 00:29:11,040 --> 00:29:13,920 Speaker 3: these carbonatable materials right, so effectively the spent or the 599 00:29:13,920 --> 00:29:16,640 Speaker 3: stuff that goes to waste, if we can add value 600 00:29:16,680 --> 00:29:20,280 Speaker 3: to that by carbonating that using either COO two emitted 601 00:29:20,320 --> 00:29:23,040 Speaker 3: by the power plant that the mine is they're currently 602 00:29:23,080 --> 00:29:25,520 Speaker 3: using to powers operations. There's a lot of conventional industry 603 00:29:25,560 --> 00:29:27,320 Speaker 3: that needs a place to put its coe too, and 604 00:29:27,440 --> 00:29:29,480 Speaker 3: we can help them store that zo too, infects that 605 00:29:29,520 --> 00:29:32,680 Speaker 3: too whilst producing a very very important and high value 606 00:29:32,720 --> 00:29:33,719 Speaker 3: lithium chemical product. 607 00:29:33,960 --> 00:29:37,480 Speaker 1: And you should acknowledge that while lithium has a carbon 608 00:29:37,560 --> 00:29:41,560 Speaker 1: cost and it's substantial, the amount of carbonate avoids through 609 00:29:41,560 --> 00:29:46,520 Speaker 1: the use of batteries and electric vehicles is much much greater. 610 00:29:47,200 --> 00:29:49,920 Speaker 1: But if you're going to scale green technologies, we ought 611 00:29:49,920 --> 00:29:53,080 Speaker 1: to be much more careful about the carbon cost of 612 00:29:53,160 --> 00:29:54,320 Speaker 1: building those technologies. 613 00:29:54,400 --> 00:29:56,720 Speaker 3: I completely agree, and that's what we need lithium, right 614 00:29:56,840 --> 00:29:59,959 Speaker 3: if you're looking through relative carbon reduction or the gatement 615 00:30:00,040 --> 00:30:02,560 Speaker 3: if you like, of transitioning towards an extory future. I 616 00:30:02,640 --> 00:30:04,960 Speaker 3: mean it is gigatons, several gig times. It is tremendous, 617 00:30:05,000 --> 00:30:06,040 Speaker 3: and we need to get there. 618 00:30:06,280 --> 00:30:06,440 Speaker 1: You know. 619 00:30:06,480 --> 00:30:10,080 Speaker 3: Our thesis is we need lithium, We need now, well yesterday, 620 00:30:10,120 --> 00:30:12,160 Speaker 3: to be honest, and we need to cost effectively, but 621 00:30:12,240 --> 00:30:14,360 Speaker 3: it has to be environmently friendly. There's no point in 622 00:30:14,560 --> 00:30:17,720 Speaker 3: using technologies which really kind of use the bones of 623 00:30:17,720 --> 00:30:20,280 Speaker 3: old dinosaurs right to kind of prop up the screen future. 624 00:30:20,680 --> 00:30:22,000 Speaker 3: And so that's what we have to try and make 625 00:30:22,000 --> 00:30:24,959 Speaker 3: it sustainable as possible, so you know, really be part 626 00:30:25,000 --> 00:30:26,719 Speaker 3: of that same ethos that we're kind of pushing towards. 627 00:30:27,000 --> 00:30:29,520 Speaker 1: And so we've got a tour of your facility and 628 00:30:29,680 --> 00:30:33,200 Speaker 1: you've done this at a lab scale that you're making 629 00:30:33,360 --> 00:30:36,280 Speaker 1: kilograms of this on a day to day basis, but 630 00:30:36,360 --> 00:30:38,960 Speaker 1: of course we're talking tons here, and so how many 631 00:30:39,040 --> 00:30:41,840 Speaker 1: years before we have thousands of tons in production using 632 00:30:41,880 --> 00:30:42,520 Speaker 1: this method. 633 00:30:42,640 --> 00:30:44,479 Speaker 3: So we're sitting at kind of like keylot scale, right. 634 00:30:44,480 --> 00:30:46,800 Speaker 3: We've done our lab and bench stop testing and that's 635 00:30:46,800 --> 00:30:49,200 Speaker 3: taken us two years to get to the stage where 636 00:30:49,200 --> 00:30:51,360 Speaker 3: we're not confident in scaling up to our pilot plants. 637 00:30:51,880 --> 00:30:54,680 Speaker 3: And so this year we while we're currently building our 638 00:30:54,680 --> 00:30:57,640 Speaker 3: pilot plant facility in Alexandria and City in Australia, and 639 00:30:57,720 --> 00:31:01,080 Speaker 3: we'll have multiple pilot plants on side seeing tens of 640 00:31:01,160 --> 00:31:03,480 Speaker 3: kilos of lithium chemical per day. So if things go 641 00:31:03,560 --> 00:31:05,800 Speaker 3: the way that we were planning them to, we will 642 00:31:05,840 --> 00:31:09,040 Speaker 3: have our first facility, our commercial administration plant operating by 643 00:31:09,120 --> 00:31:11,280 Speaker 3: twenty twenty six, twenty twenty seven, and then scale of 644 00:31:11,280 --> 00:31:14,000 Speaker 3: that'll be between you know, one and five thousand tons pernum. 645 00:31:14,160 --> 00:31:15,760 Speaker 1: And where will it be based? 646 00:31:16,040 --> 00:31:18,240 Speaker 3: Very good question. So if you're looking at where lithium 647 00:31:18,320 --> 00:31:21,080 Speaker 3: is primarily based, a Western Australia has a tremendous amount 648 00:31:21,120 --> 00:31:24,080 Speaker 3: of spodyman but the US, right, the US is pushing 649 00:31:24,200 --> 00:31:26,520 Speaker 3: very very hard into on shoring it's critical mineral supply 650 00:31:26,640 --> 00:31:29,600 Speaker 3: and really supporting this battery production in our electric future. 651 00:31:29,880 --> 00:31:32,600 Speaker 3: And at this stage it's looking like either US. There's 652 00:31:32,600 --> 00:31:35,240 Speaker 3: a lot of local quality lithum resources and tons of 653 00:31:35,280 --> 00:31:37,120 Speaker 3: lithium in general, which the need to find a better 654 00:31:37,160 --> 00:31:39,200 Speaker 3: way to process a Western Australia, which is where the 655 00:31:39,280 --> 00:31:41,480 Speaker 3: vast majority of kind of the hard rockithum comes from 656 00:31:41,520 --> 00:31:43,400 Speaker 3: at the moment. There's a lot of support from the 657 00:31:43,440 --> 00:31:45,480 Speaker 3: government in the US, which is very attractive for not 658 00:31:45,520 --> 00:31:49,320 Speaker 3: only US but anybody looking to hasten that transition. And 659 00:31:49,360 --> 00:31:51,480 Speaker 3: so if we can get support from the US, and 660 00:31:51,760 --> 00:31:54,200 Speaker 3: given the credituality of lithium in general, think we will 661 00:31:54,240 --> 00:31:56,280 Speaker 3: be able to it makes a lot of sense for us. 662 00:31:56,520 --> 00:31:58,280 Speaker 1: Well, thank you and good luck scaling up. 663 00:31:58,560 --> 00:31:59,960 Speaker 3: No, thanks very much for having me. It was great. 664 00:32:04,480 --> 00:32:07,400 Speaker 1: Thank you for listening to Zero.
