1 00:00:01,280 --> 00:00:04,080 Speaker 1: Hey, it's Aukshat. I'll be going to COP twenty eight 2 00:00:04,320 --> 00:00:07,000 Speaker 1: in Dubai later this month. I'd love to find a 3 00:00:07,000 --> 00:00:09,680 Speaker 1: way to answer the many questions you may have of 4 00:00:09,760 --> 00:00:13,360 Speaker 1: the United Nations Climate Conference. Check out the show notes 5 00:00:13,400 --> 00:00:16,680 Speaker 1: for details on how to send us your questions. Thanks 6 00:00:16,720 --> 00:00:29,240 Speaker 1: for listening. Welcome to Zero. I'm Akshatrati. This week Reduce, reuse, Remove. 7 00:00:42,120 --> 00:00:44,760 Speaker 1: The sad reality is that even though the world has 8 00:00:44,880 --> 00:00:48,000 Speaker 1: clear climate goals, it was late in starting to do 9 00:00:48,120 --> 00:00:52,279 Speaker 1: something about them. That's why meeting these goals will not 10 00:00:52,400 --> 00:00:55,640 Speaker 1: just mean an end to dumping greenhouse gas emissions, but 11 00:00:55,960 --> 00:00:59,600 Speaker 1: also undoing some of that damage by drawing down carbon 12 00:00:59,640 --> 00:01:03,120 Speaker 1: diox from the air. That's what we are going to 13 00:01:03,160 --> 00:01:05,920 Speaker 1: talk about today. This is the second in a series 14 00:01:06,080 --> 00:01:08,440 Speaker 1: that looks at the state of carbon capture and carbon 15 00:01:08,520 --> 00:01:12,800 Speaker 1: removal technologies. Last week I talked to Emily Grubert. She's 16 00:01:12,800 --> 00:01:15,880 Speaker 1: a professor at Notre Dame University, and we talked about 17 00:01:15,920 --> 00:01:20,039 Speaker 1: the potential and limits of technologies that trap emissions before 18 00:01:20,120 --> 00:01:23,640 Speaker 1: they exit a smokestack. That type of coin source carbon 19 00:01:23,680 --> 00:01:26,880 Speaker 1: capture is expected to do the heavy lifting as the 20 00:01:26,920 --> 00:01:30,520 Speaker 1: world gets close to net zero by twenty fifty. But 21 00:01:30,760 --> 00:01:33,200 Speaker 1: as we get closer to that date, which is only 22 00:01:33,240 --> 00:01:36,080 Speaker 1: twenty seven years from now, that zero models say that 23 00:01:36,080 --> 00:01:39,280 Speaker 1: carbon removal technologies will have to kick into gear. The 24 00:01:39,319 --> 00:01:43,640 Speaker 1: International Energy Agency suggests the world needs one billion tons 25 00:01:43,680 --> 00:01:46,600 Speaker 1: of carbon dioxide removed from the air by twenty fifty. 26 00:01:47,319 --> 00:01:50,960 Speaker 1: Currently we draw down less than ten thousand tons each year. 27 00:01:52,080 --> 00:01:55,160 Speaker 2: I think it's really indisputable right now that we will 28 00:01:55,640 --> 00:02:01,080 Speaker 2: overrun our climate safety barriers, and because of that we 29 00:02:01,200 --> 00:02:04,600 Speaker 2: must be able to remove CO two from the atmosphere. 30 00:02:04,680 --> 00:02:06,560 Speaker 3: You can't have net zero without a negative. 31 00:02:06,720 --> 00:02:11,200 Speaker 1: The science is clear industrial carbon removal is a necessary 32 00:02:11,240 --> 00:02:15,200 Speaker 1: part of our climate toolbox. Point source carbon capture is 33 00:02:15,360 --> 00:02:18,800 Speaker 1: cheaper than carbon removal. It costs less than sixty dollars 34 00:02:18,880 --> 00:02:21,559 Speaker 1: a ton to stop CO two from entering the atmosphere, 35 00:02:22,040 --> 00:02:24,680 Speaker 1: whereas it costs ten times as much to pull it 36 00:02:24,720 --> 00:02:27,720 Speaker 1: back down from the air. If carbon removal is to 37 00:02:27,760 --> 00:02:31,160 Speaker 1: play a meaningful role in reaching climate goals, the cost 38 00:02:31,200 --> 00:02:33,799 Speaker 1: has to come down to about one hundred dollars a ton. 39 00:02:34,520 --> 00:02:37,800 Speaker 1: That's how much European companies pay currently for every ton 40 00:02:37,840 --> 00:02:39,520 Speaker 1: of CO two pollution they put out. 41 00:02:40,120 --> 00:02:43,680 Speaker 3: We're at a point where avoiding emissions since the atmosphere 42 00:02:43,919 --> 00:02:44,960 Speaker 3: is no longer enough. 43 00:02:45,560 --> 00:02:48,959 Speaker 1: This is my guest today, Jennifer Wilcox, a professor of 44 00:02:49,040 --> 00:02:52,720 Speaker 1: chemical engineering at the University of Pennsylvania. She is currently 45 00:02:52,800 --> 00:02:55,760 Speaker 1: on leave from that position to oversee the Office of 46 00:02:55,800 --> 00:02:59,680 Speaker 1: Fossil Energy and Carbon Management at the US Department of Energy. 47 00:03:00,280 --> 00:03:03,200 Speaker 1: The US government has devoted billions of dollars to scaling 48 00:03:03,200 --> 00:03:07,680 Speaker 1: carbon capture technology, and it is now funding carbon removal projects. 49 00:03:08,200 --> 00:03:10,880 Speaker 1: I wanted to ask Jen about the US strategy for 50 00:03:10,919 --> 00:03:14,320 Speaker 1: getting carbon removal out of the research phase, what happens 51 00:03:14,400 --> 00:03:17,000 Speaker 1: if we don't hit the price points we need, and 52 00:03:17,120 --> 00:03:20,200 Speaker 1: why for once it was private industry that took the 53 00:03:20,280 --> 00:03:35,440 Speaker 1: lead on developing this clean technology. Jen, welcome to the show. 54 00:03:35,920 --> 00:03:36,720 Speaker 3: Thanks for having me. 55 00:03:37,280 --> 00:03:40,680 Speaker 1: Let's start with how you got to run the Office 56 00:03:40,680 --> 00:03:42,880 Speaker 1: of Fossil Energy and Carbon Management. 57 00:03:43,560 --> 00:03:47,680 Speaker 3: Sure, so, back in twenty twenty, I was approached and 58 00:03:47,800 --> 00:03:51,280 Speaker 3: asked if I would be interested in coming into the 59 00:03:51,680 --> 00:03:55,520 Speaker 3: new administration and overseeing the work and the Office of 60 00:03:55,520 --> 00:03:58,160 Speaker 3: Fossil Energy at that time, and so I had to 61 00:03:58,240 --> 00:04:00,880 Speaker 3: learn a little bit about what that meant. And my 62 00:04:00,920 --> 00:04:04,839 Speaker 3: background is in chemical engineering and getting excited about how 63 00:04:04,880 --> 00:04:09,960 Speaker 3: we separate things like CO two, Whether it's from a 64 00:04:10,000 --> 00:04:12,400 Speaker 3: power plant, or whether it's from a cement plant, or 65 00:04:12,400 --> 00:04:15,120 Speaker 3: maybe from the atmosphere, which is a lot more difficult 66 00:04:15,200 --> 00:04:18,039 Speaker 3: to do. Back in twenty twelve, I did write a 67 00:04:18,080 --> 00:04:22,840 Speaker 3: textbook on carbon capture, and really the reason for me 68 00:04:22,920 --> 00:04:25,680 Speaker 3: of doing that is that I felt that there was 69 00:04:25,720 --> 00:04:29,360 Speaker 3: a lack of human capital in this space that were 70 00:04:29,480 --> 00:04:32,200 Speaker 3: educated in a way that could help to contribute in 71 00:04:32,240 --> 00:04:36,200 Speaker 3: a meaningful approach to helping us to making sure that 72 00:04:36,320 --> 00:04:39,599 Speaker 3: we have this in our toolkit as we are trying 73 00:04:39,640 --> 00:04:43,560 Speaker 3: to achieve net zero goals. And so when I came 74 00:04:43,600 --> 00:04:47,279 Speaker 3: into the position, one of the asks was how can 75 00:04:47,320 --> 00:04:52,280 Speaker 3: we reconcile investments in this space with climate goals. So 76 00:04:52,320 --> 00:04:56,440 Speaker 3: in the first year, we reorganized our entire office and 77 00:04:56,480 --> 00:04:59,840 Speaker 3: we added two keywords carbon management to the office because 78 00:04:59,839 --> 00:05:01,479 Speaker 3: that's big part of what we do. 79 00:05:02,040 --> 00:05:05,480 Speaker 1: Why does having those extra to words, having a sort 80 00:05:05,480 --> 00:05:07,520 Speaker 1: of a new brand so to speak, matter. 81 00:05:07,839 --> 00:05:11,680 Speaker 3: Well, because we're at a point where avoiding emissions into 82 00:05:11,680 --> 00:05:15,680 Speaker 3: the atmosphere is no longer enough. And I think, you know, 83 00:05:15,760 --> 00:05:19,880 Speaker 3: previously when we were only fossil energy before this administration, 84 00:05:19,960 --> 00:05:22,400 Speaker 3: I think the perspective was more about how do we 85 00:05:22,440 --> 00:05:25,000 Speaker 3: make sure that everybody has access to energy in the 86 00:05:25,080 --> 00:05:27,960 Speaker 3: United States, not just access to energy, but that that 87 00:05:28,080 --> 00:05:33,120 Speaker 3: energy is affordable and it's clean. And carbon management more 88 00:05:33,160 --> 00:05:37,200 Speaker 3: broadly has another aspect. Right, It's not just about avoiding 89 00:05:37,200 --> 00:05:42,720 Speaker 3: emissions into the atmosphere. It's about recognizing that the accumulated 90 00:05:42,760 --> 00:05:47,680 Speaker 3: CO two in the atmosphere is mostly also from legacy 91 00:05:47,880 --> 00:05:52,680 Speaker 3: fossil and so recognizing that that should be our mandate too. Right, 92 00:05:52,720 --> 00:05:56,560 Speaker 3: as we look at carbon dioxide removal tackling the accumulated 93 00:05:56,600 --> 00:06:00,120 Speaker 3: CO two that's in the atmosphere, that it may make 94 00:06:00,240 --> 00:06:03,960 Speaker 3: sense that the Office of Fossil Energy is tackling that 95 00:06:04,000 --> 00:06:07,960 Speaker 3: one because most of it was sourced from hydrocarbons that 96 00:06:08,000 --> 00:06:09,160 Speaker 3: we got deep underground. 97 00:06:09,760 --> 00:06:14,920 Speaker 1: In the past decade, we have started talking about carbon removal, 98 00:06:15,080 --> 00:06:18,640 Speaker 1: which is, as you said, taking down the legacy emissions 99 00:06:18,640 --> 00:06:22,159 Speaker 1: that already exist in the atmosphere. Because we've left the 100 00:06:22,200 --> 00:06:25,279 Speaker 1: climate problem so late that to be able to meet 101 00:06:25,279 --> 00:06:27,120 Speaker 1: our climate goals, we are going to have to do 102 00:06:27,200 --> 00:06:31,320 Speaker 1: some of that carbon removal. And so somebody coming cold 103 00:06:31,320 --> 00:06:36,760 Speaker 1: to this subject, how would you separate what is traditional 104 00:06:36,839 --> 00:06:43,240 Speaker 1: carbon capture technology versus what is an important and multifaceted 105 00:06:43,360 --> 00:06:46,400 Speaker 1: way in which you could actually remove carbon dioxide from 106 00:06:46,440 --> 00:06:46,800 Speaker 1: the air. 107 00:06:47,200 --> 00:06:50,280 Speaker 3: Yeah, so you know, how do you separate? We have 108 00:06:50,360 --> 00:06:53,160 Speaker 3: been also just trying to keep these tools separate as well, 109 00:06:53,200 --> 00:06:57,000 Speaker 3: because they're so easy to conflate. So if you're looking 110 00:06:57,040 --> 00:06:59,359 Speaker 3: at a point source and you're retrofitting it with a 111 00:06:59,560 --> 00:07:03,760 Speaker 3: carbon chapter technology, you're avoiding the emissions from ever entering 112 00:07:03,760 --> 00:07:07,560 Speaker 3: the atmosphere. We recognize in the United States there's a 113 00:07:07,600 --> 00:07:11,560 Speaker 3: concept of committed emissions. A lot of power plants, you know, 114 00:07:11,600 --> 00:07:14,320 Speaker 3: were built thirty plus years ago and they'll probably retire, 115 00:07:14,440 --> 00:07:18,880 Speaker 3: especially as we you know, squeeze our wedge of dependence 116 00:07:18,920 --> 00:07:21,760 Speaker 3: on fossil energy down and we have so much opportunity 117 00:07:21,760 --> 00:07:25,000 Speaker 3: in the United States for renewables, but there are going 118 00:07:25,080 --> 00:07:28,239 Speaker 3: to still be some units that are going to continue 119 00:07:28,280 --> 00:07:31,920 Speaker 3: to operate on fossil for the unforeseeable future. And what 120 00:07:32,440 --> 00:07:35,680 Speaker 3: we need to think about is that it is cheaper 121 00:07:35,720 --> 00:07:39,480 Speaker 3: and easier from an economic perspective to retrofit the units 122 00:07:39,480 --> 00:07:42,679 Speaker 3: that are going to persist because they're new coming online 123 00:07:42,680 --> 00:07:45,760 Speaker 3: today in some cases. So there's going to be some 124 00:07:46,080 --> 00:07:49,480 Speaker 3: amount of carbon capturing storage that's going to be point source. 125 00:07:50,000 --> 00:07:53,080 Speaker 3: And the reason why that's important is because now it 126 00:07:53,280 --> 00:07:57,200 Speaker 3: reduces the burden of carbon removal. When we think of 127 00:07:57,240 --> 00:07:59,800 Speaker 3: carbon removal, you know, we all use it so loosely 128 00:07:59,800 --> 00:08:01,840 Speaker 3: now because we recognize that we have to take CO 129 00:08:02,040 --> 00:08:05,880 Speaker 3: two out of the accumulated pool in the atmosphere. All 130 00:08:05,880 --> 00:08:08,960 Speaker 3: climate models tell us we need it, but not we 131 00:08:09,000 --> 00:08:11,480 Speaker 3: need it because we're not going to do deep decarbonization 132 00:08:11,600 --> 00:08:14,560 Speaker 3: fast enough. We actually need it for truly hard to 133 00:08:14,600 --> 00:08:19,360 Speaker 3: decarbonize sectors. We need it for the agricultural sector, We 134 00:08:19,440 --> 00:08:23,480 Speaker 3: need it for aspects of shipping, in aviation that are 135 00:08:23,520 --> 00:08:26,840 Speaker 3: truly hard to decarbonize. And so if we look at 136 00:08:26,840 --> 00:08:30,320 Speaker 3: our emissions in the United States, you know, roughly five 137 00:08:30,360 --> 00:08:33,600 Speaker 3: and a half to six gigatons of CO two every year, 138 00:08:33,920 --> 00:08:37,240 Speaker 3: and when you do the bottom up calculation of thinking 139 00:08:37,320 --> 00:08:40,600 Speaker 3: about what's truly truly hard to decarbonize, it still adds 140 00:08:40,640 --> 00:08:44,600 Speaker 3: up to a little over a gigaton. So that's carbon removal. 141 00:08:44,840 --> 00:08:48,200 Speaker 3: That's the role of carbon removal is to counterbalance truly 142 00:08:48,240 --> 00:08:52,880 Speaker 3: hard to decarbonize sectors, not to counter balance sectors by 143 00:08:52,880 --> 00:08:56,000 Speaker 3: which we have technologies that we can decarbonize. 144 00:08:56,160 --> 00:08:59,600 Speaker 1: When you're talking gigatons, you mean billion tons, right, yes, 145 00:09:00,040 --> 00:09:03,560 Speaker 1: And when you say truly hard to decarbonize. What's the 146 00:09:03,800 --> 00:09:07,040 Speaker 1: hard part? Is it just we don't know how to 147 00:09:07,080 --> 00:09:11,520 Speaker 1: do it, or it's too expensive, or it's politically impossible. 148 00:09:11,800 --> 00:09:12,640 Speaker 1: What is hard? 149 00:09:13,400 --> 00:09:15,360 Speaker 3: Hard means it's not ready today. 150 00:09:15,800 --> 00:09:17,880 Speaker 1: So it's technologically not ready today. 151 00:09:18,080 --> 00:09:21,880 Speaker 3: Well, so technologically not ready, yeah, it's at an R 152 00:09:21,920 --> 00:09:25,400 Speaker 3: and D phase, maybe not at the demonstration phase yet, 153 00:09:25,679 --> 00:09:28,760 Speaker 3: or there's other reasons too write. So it could also 154 00:09:28,840 --> 00:09:31,640 Speaker 3: be that when you look at the aviation sector, we 155 00:09:31,720 --> 00:09:35,720 Speaker 3: get very excited about sustainable aviation fuel, but the question 156 00:09:35,840 --> 00:09:38,359 Speaker 3: is is it going to do it all right? Sustainable 157 00:09:38,400 --> 00:09:41,400 Speaker 3: biomass as a feedstock, do we have enough? When do 158 00:09:41,480 --> 00:09:44,920 Speaker 3: we start competing for food? And even an aspect of 159 00:09:44,960 --> 00:09:48,720 Speaker 3: sustainable aviation is also downstream use of CO two CO 160 00:09:48,920 --> 00:09:52,080 Speaker 3: two with clean hydrogen for synthetic fuels that could play 161 00:09:52,200 --> 00:09:54,560 Speaker 3: a role, But the question is are we going to 162 00:09:54,640 --> 00:09:59,679 Speaker 3: be able to close that wedge quick enough? And so 163 00:10:00,520 --> 00:10:04,400 Speaker 3: it's really unclear even how much carbon removal we're going 164 00:10:04,480 --> 00:10:07,360 Speaker 3: to need to offset the truly hard to decarbonize sectors, 165 00:10:08,120 --> 00:10:10,800 Speaker 3: and if we don't invest today, we're just not going 166 00:10:10,840 --> 00:10:12,839 Speaker 3: to even have it available to us in time. 167 00:10:14,679 --> 00:10:17,360 Speaker 1: Before we discuss the challenge of doing this at scale. 168 00:10:17,480 --> 00:10:21,080 Speaker 1: Let's look at what types of technologies are available. It's 169 00:10:21,080 --> 00:10:25,160 Speaker 1: one thing that keeps surprising me. Point source carbon capture 170 00:10:25,200 --> 00:10:29,320 Speaker 1: typically does just one thing. A chemical process separates our 171 00:10:29,440 --> 00:10:33,000 Speaker 1: carbon dioxide from a mixture of gases before they go 172 00:10:33,040 --> 00:10:37,000 Speaker 1: into a smokestack. Carbon removal can piggyback on that technology. 173 00:10:37,559 --> 00:10:41,080 Speaker 1: Swiss startup climb Works uses the same chemical process, but 174 00:10:41,200 --> 00:10:46,240 Speaker 1: instead of industrial gases, it uses air as the input. However, 175 00:10:46,400 --> 00:10:49,920 Speaker 1: carbon removal technologies can also get weird. I wrote about 176 00:10:49,920 --> 00:10:53,320 Speaker 1: an Australian startup called inter Earth, which takes trees and 177 00:10:53,360 --> 00:10:57,240 Speaker 1: then buries them in highly salty soils. The trees capture 178 00:10:57,280 --> 00:11:00,480 Speaker 1: certo from the air and the salty soils stop it 179 00:11:00,520 --> 00:11:05,680 Speaker 1: from degrading, thus carbon removed. Another idea is to use 180 00:11:05,760 --> 00:11:09,520 Speaker 1: waste from agriculture, turn it into a carbonaceous black goop 181 00:11:09,800 --> 00:11:14,480 Speaker 1: not unlike oil, then sync that deep underground. That's what 182 00:11:14,679 --> 00:11:18,120 Speaker 1: US startup charm Industrial does, and there are tens of 183 00:11:18,160 --> 00:11:21,520 Speaker 1: other wacky ideas available. It's up to investors and governments 184 00:11:21,520 --> 00:11:24,880 Speaker 1: to back the ones that they think are scalable. Carbon 185 00:11:24,920 --> 00:11:28,240 Speaker 1: removal startups have received hundreds of millions of dollars in funding. 186 00:11:28,520 --> 00:11:31,959 Speaker 1: Most of that has come from private industry. The Frontier Fund, 187 00:11:32,080 --> 00:11:34,840 Speaker 1: led by the payments company Stripe, has promised to buy 188 00:11:34,920 --> 00:11:38,920 Speaker 1: one billion dollars of carbon removal. Bill Gates also funds 189 00:11:38,920 --> 00:11:41,640 Speaker 1: many of these startups, and he pays for his own 190 00:11:41,679 --> 00:11:47,240 Speaker 1: carbon removal at a price of six hundred dollars a ton. Now, 191 00:11:47,280 --> 00:11:50,960 Speaker 1: a lot of the green technologies that got started started 192 00:11:51,559 --> 00:11:54,800 Speaker 1: through government R and D. You know, very early solar 193 00:11:54,840 --> 00:11:58,440 Speaker 1: research happened in labs, then it happened in some private industry. 194 00:11:58,800 --> 00:12:03,440 Speaker 1: Same thing with battery. Carbon removal technologies, however, have had 195 00:12:03,480 --> 00:12:05,800 Speaker 1: a different route. A lot of the scale up that 196 00:12:05,800 --> 00:12:08,640 Speaker 1: has happened in the past decade has been driven by 197 00:12:08,760 --> 00:12:12,840 Speaker 1: private industry, even before the government stepped in. You know, 198 00:12:12,880 --> 00:12:16,600 Speaker 1: we had a billion dollar fund launched last year that 199 00:12:16,760 --> 00:12:21,480 Speaker 1: is private industry trying to push carbon removal. Why do 200 00:12:21,559 --> 00:12:22,800 Speaker 1: you think that is the case? 201 00:12:23,600 --> 00:12:25,680 Speaker 3: I mean, we've seen a lot of corporations that have 202 00:12:25,880 --> 00:12:31,120 Speaker 3: announced net zero pledges back got some momentum in the space, 203 00:12:31,280 --> 00:12:34,960 Speaker 3: and the reason is they're recognizing just within their own 204 00:12:35,559 --> 00:12:40,000 Speaker 3: framework of their organization that they can control for the 205 00:12:40,000 --> 00:12:43,079 Speaker 3: most part, those Scope one emissions right even Scope two 206 00:12:43,280 --> 00:12:46,959 Speaker 3: where they're accessing their electricity from. But when you look 207 00:12:47,000 --> 00:12:53,640 Speaker 3: at scope three cement, steel, paper, aviation, food, even some 208 00:12:53,720 --> 00:12:58,040 Speaker 3: of these are very difficult to decarbonize sectors in terms 209 00:12:58,080 --> 00:13:01,360 Speaker 3: of a company that wants to reach net zero, they 210 00:13:01,400 --> 00:13:05,319 Speaker 3: can't control those supply streams and they don't exist today 211 00:13:05,320 --> 00:13:08,440 Speaker 3: in a low carbon way, and so the only way 212 00:13:08,800 --> 00:13:12,679 Speaker 3: to achieve net zero for those groups was to have 213 00:13:12,720 --> 00:13:15,840 Speaker 3: carbon removal as a tool to counterbalance the scope through 214 00:13:15,880 --> 00:13:19,600 Speaker 3: emissions in their portfolio. And so, you know, you started 215 00:13:19,600 --> 00:13:22,800 Speaker 3: to see a lot of interest in some of the 216 00:13:22,840 --> 00:13:27,080 Speaker 3: forest offset programs. And then the wonderful thing is is 217 00:13:27,160 --> 00:13:32,800 Speaker 3: that these companies also have really thoughtful leadership and recognizing 218 00:13:33,320 --> 00:13:36,679 Speaker 3: when you dig into those nature based offsets that are 219 00:13:36,679 --> 00:13:41,400 Speaker 3: available that were not very expensive, that there's not a 220 00:13:41,400 --> 00:13:44,400 Speaker 3: lot of durability in the removal. In fact, a lot 221 00:13:44,400 --> 00:13:48,560 Speaker 3: of uncertainty because in some of those nature based approaches too, 222 00:13:48,679 --> 00:13:52,360 Speaker 3: you see a lot of reversal carbon sinks that we 223 00:13:52,440 --> 00:13:56,400 Speaker 3: rely on even on our climate models becoming carbon sources 224 00:13:56,520 --> 00:13:59,880 Speaker 3: with forest fires. And so that started to bring more 225 00:14:00,160 --> 00:14:04,400 Speaker 3: tension to the very few players several years ago in 226 00:14:04,559 --> 00:14:07,920 Speaker 3: terms of the technological approaches to removing carbon from the 227 00:14:07,960 --> 00:14:13,240 Speaker 3: atmosphere and representing a durable approach to carbon removal. 228 00:14:13,200 --> 00:14:16,920 Speaker 1: In a way, you are saying, there's the benevolent corporation 229 00:14:17,559 --> 00:14:21,840 Speaker 1: that is thinking about climate in a sensible way and realizing, oh, 230 00:14:21,920 --> 00:14:24,360 Speaker 1: we have goals. To hit those goals, we're going to 231 00:14:24,480 --> 00:14:27,400 Speaker 1: have to do so many things. Reduce our emissions first, 232 00:14:27,400 --> 00:14:30,560 Speaker 1: but then what remains we have to remove and because 233 00:14:30,680 --> 00:14:34,080 Speaker 1: offsets nature based offsets haven't worked out, have been caught 234 00:14:34,280 --> 00:14:37,120 Speaker 1: either in a wildfire or in greenwashing, we need to 235 00:14:37,160 --> 00:14:39,960 Speaker 1: find more durable ways to do it. There is the 236 00:14:40,040 --> 00:14:43,360 Speaker 1: non benevolent version of the corporation, which is it's there 237 00:14:43,400 --> 00:14:47,480 Speaker 1: to maximize profits, it is there to protect its reputation, 238 00:14:48,200 --> 00:14:51,800 Speaker 1: and it is making sure that through these small investments 239 00:14:51,880 --> 00:14:54,560 Speaker 1: here or there, which sound like big numbers given the 240 00:14:54,640 --> 00:14:57,960 Speaker 1: relative scale of the industry, they're sort of getting away 241 00:14:58,000 --> 00:15:01,280 Speaker 1: with it. They're dealing the inn which is to reduce 242 00:15:01,320 --> 00:15:05,200 Speaker 1: their emissions really drastically this decade, but instead telling you 243 00:15:05,280 --> 00:15:06,920 Speaker 1: we're doing the right thing, we're going to invest in 244 00:15:07,000 --> 00:15:09,800 Speaker 1: the right solutions, how do we handle the sort of 245 00:15:09,880 --> 00:15:14,000 Speaker 1: moral hazard problem that carbon removal technologies throw at you, 246 00:15:14,080 --> 00:15:17,680 Speaker 1: which is, yes, science says it's needed, it's good to 247 00:15:17,720 --> 00:15:20,800 Speaker 1: invest in them, but aren't we using it as an 248 00:15:20,840 --> 00:15:23,120 Speaker 1: excuse to not reduce emissions today. 249 00:15:23,640 --> 00:15:26,880 Speaker 3: Yeah, I saw that too, and so one of the 250 00:15:26,920 --> 00:15:30,400 Speaker 3: things that we've been doing is, as you know, and 251 00:15:30,440 --> 00:15:33,120 Speaker 3: we'll talk probably about the infrastructure law dollars in a 252 00:15:33,160 --> 00:15:39,680 Speaker 3: little bit, but there's dollars within that legislation that allows 253 00:15:39,760 --> 00:15:44,560 Speaker 3: us to invest in the point source capture, decarbonizing facilities, 254 00:15:44,600 --> 00:15:47,840 Speaker 3: and just focusing on industry for a minute, when you 255 00:15:47,880 --> 00:15:53,480 Speaker 3: look at Scope three emissions of some of these groups cement, paper, steel, 256 00:15:54,120 --> 00:15:58,120 Speaker 3: it's a lot cheaper to invest in decarbonizing those industries 257 00:15:58,280 --> 00:16:01,120 Speaker 3: than it is to use carbon remove to offset. But 258 00:16:01,160 --> 00:16:04,600 Speaker 3: the reality is is that CO two capture has not 259 00:16:04,680 --> 00:16:09,480 Speaker 3: been demonstrated on those facilities yet. So we have the 260 00:16:09,520 --> 00:16:13,480 Speaker 3: Petronova example. We have another example where we can make 261 00:16:13,560 --> 00:16:17,960 Speaker 3: hydrogen through steam methane reforming with carbon capture. We certainly 262 00:16:18,000 --> 00:16:21,280 Speaker 3: know how to take CO two out of the fermentation 263 00:16:21,440 --> 00:16:25,600 Speaker 3: process of bioethanol. So we have some great examples to 264 00:16:25,640 --> 00:16:28,160 Speaker 3: point to where we've tested that technology and it works 265 00:16:28,160 --> 00:16:31,000 Speaker 3: for those cases, but we still need to demonstrate it 266 00:16:31,040 --> 00:16:33,160 Speaker 3: on a blast furnace, as a steel plant and out 267 00:16:33,160 --> 00:16:35,560 Speaker 3: of paper mill and things like that. And so we 268 00:16:35,720 --> 00:16:37,920 Speaker 3: have funding to be able to do that. 269 00:16:44,960 --> 00:16:47,800 Speaker 1: After the break, we get into the numbers. How much 270 00:16:47,840 --> 00:16:50,840 Speaker 1: does the US spend on carbon removal and what happens 271 00:16:50,880 --> 00:16:52,960 Speaker 1: if we don't get the price down to one hundred 272 00:16:52,960 --> 00:17:08,440 Speaker 1: dollars a ton. So let's just talk numbers the government 273 00:17:08,760 --> 00:17:12,240 Speaker 1: programs and the money that's being spent. Let's just start 274 00:17:12,240 --> 00:17:16,040 Speaker 1: with the big programs that are in play after you 275 00:17:16,080 --> 00:17:17,040 Speaker 1: got into office. 276 00:17:17,800 --> 00:17:21,200 Speaker 3: So here we've been talking about carbon removals. We'll start there. 277 00:17:21,240 --> 00:17:24,520 Speaker 3: So we have three point five billion dollars to develop 278 00:17:24,640 --> 00:17:29,240 Speaker 3: build out four director capture hubs, each capable of removing 279 00:17:29,280 --> 00:17:31,960 Speaker 3: a million tons of SEO two per year, and we 280 00:17:32,119 --> 00:17:35,760 Speaker 3: recently awarded two demonstrations. 281 00:17:36,560 --> 00:17:40,160 Speaker 1: Those two hubs will back two different types of technologies. First, 282 00:17:40,200 --> 00:17:44,200 Speaker 1: we'll see carbon Engineering working with Occidental Petroleum to trap 283 00:17:44,320 --> 00:17:48,120 Speaker 1: ZEO two using liquid chemicals. The other one we'll have 284 00:17:48,240 --> 00:17:51,119 Speaker 1: Airloom working with climb Works doing the same but with 285 00:17:51,280 --> 00:17:52,920 Speaker 1: solid absorbents instead. 286 00:17:53,480 --> 00:17:57,479 Speaker 3: And then what's also exciting is recognizing that there's just 287 00:17:57,520 --> 00:18:01,160 Speaker 3: such a portfolio of technologies at different stages of readiness today, 288 00:18:01,920 --> 00:18:05,600 Speaker 3: and we wanted to make sure that we're also investing 289 00:18:05,640 --> 00:18:10,199 Speaker 3: in all those ideas and across the United States, and 290 00:18:10,240 --> 00:18:15,159 Speaker 3: so We also awarded roughly twenty projects at concept in 291 00:18:15,280 --> 00:18:18,240 Speaker 3: front and engineering design at one hundred million dollars collectively, 292 00:18:18,960 --> 00:18:21,960 Speaker 3: recognizing that these are systems that are going to be 293 00:18:21,960 --> 00:18:24,760 Speaker 3: outside and in the elements, right, so how are they 294 00:18:24,760 --> 00:18:28,200 Speaker 3: going to perform based upon different conditions across the United States? 295 00:18:28,440 --> 00:18:31,160 Speaker 3: And what energy resources are they coupling too in order 296 00:18:31,200 --> 00:18:32,520 Speaker 3: to maximize carbon removal. 297 00:18:32,800 --> 00:18:36,840 Speaker 1: The energy equation is stark. Removing one ton of carbon 298 00:18:36,840 --> 00:18:41,800 Speaker 1: dioxide using directair capture can take anywhere between a thousand 299 00:18:42,040 --> 00:18:46,679 Speaker 1: and two thousand kilowot hours of energy. That is roughly 300 00:18:46,760 --> 00:18:50,800 Speaker 1: between four to eight months of electricity that I'm consuming 301 00:18:50,840 --> 00:18:53,760 Speaker 1: with my wife in a London flat. It's a lot 302 00:18:53,840 --> 00:18:58,840 Speaker 1: of electricity. How are we going to justify requiring the 303 00:18:58,880 --> 00:19:03,440 Speaker 1: buildout of so much energy infrastructure that we already are 304 00:19:03,440 --> 00:19:06,840 Speaker 1: doing to try and replace fossil fuel energy infrastructure, but 305 00:19:06,880 --> 00:19:09,360 Speaker 1: we are going to require even more in addition. 306 00:19:09,840 --> 00:19:11,479 Speaker 3: Yeah, I mean, I think that's why we have to 307 00:19:11,480 --> 00:19:16,200 Speaker 3: think about these first of a kind projects as responsible 308 00:19:16,720 --> 00:19:19,159 Speaker 3: projects that we can do in a meaningful way that 309 00:19:19,200 --> 00:19:21,399 Speaker 3: can serve as examples for the end of a kind. 310 00:19:22,080 --> 00:19:26,360 Speaker 3: And one example is citing in a way that you're 311 00:19:26,400 --> 00:19:30,200 Speaker 3: not competing for low carbon energy that would otherwise go 312 00:19:30,760 --> 00:19:35,080 Speaker 3: for decarbonizing fossil power for instance, that needs to be prioritized. 313 00:19:35,600 --> 00:19:39,920 Speaker 1: Now, there are various estimates of the cost of carbon removal. 314 00:19:40,160 --> 00:19:42,960 Speaker 1: One from Howard Herdzock at MIT, who's been a long 315 00:19:43,000 --> 00:19:46,680 Speaker 1: time researcher in this space, comes between six hundred dollars 316 00:19:46,760 --> 00:19:49,560 Speaker 1: and a thousand dollars a ton. One from David Keith 317 00:19:49,720 --> 00:19:52,680 Speaker 1: at Howard, who also is the founder of Carbon Engineering, 318 00:19:52,760 --> 00:19:55,000 Speaker 1: which is one of the companies that got the award 319 00:19:55,040 --> 00:19:58,520 Speaker 1: for our Director Capture Hub alongside others, has put it 320 00:19:58,600 --> 00:20:01,240 Speaker 1: between three hundred dollars and four and twenty five dollars 321 00:20:01,320 --> 00:20:04,159 Speaker 1: a ton. The goal eventually is to try and get 322 00:20:04,200 --> 00:20:06,200 Speaker 1: it all down to one hundred dollars a ton, sort 323 00:20:06,200 --> 00:20:09,280 Speaker 1: of a realistic number. That's about how much the carbon 324 00:20:09,920 --> 00:20:13,240 Speaker 1: price is right now here in Europe, for example. How 325 00:20:13,320 --> 00:20:18,840 Speaker 1: realistic is that aim, because yes, we've seen cost declines 326 00:20:18,880 --> 00:20:22,320 Speaker 1: in green technologies for solar, for wind, for batteries for 327 00:20:22,400 --> 00:20:25,840 Speaker 1: electric cars, but they have come because of what is 328 00:20:25,960 --> 00:20:30,240 Speaker 1: unit economics. They make millions of the same thing again 329 00:20:30,280 --> 00:20:33,000 Speaker 1: and again, and they reduce the price. In direct air 330 00:20:33,080 --> 00:20:36,160 Speaker 1: capture or carbon removal, you could get some unit economics, 331 00:20:36,280 --> 00:20:39,680 Speaker 1: but we're still not talking millions of them. So how 332 00:20:39,680 --> 00:20:43,840 Speaker 1: realistic do you think is the priced target that we 333 00:20:43,960 --> 00:20:45,520 Speaker 1: have for carbon removal? 334 00:20:46,240 --> 00:20:49,560 Speaker 3: So the idea with the carbon negative shot and that 335 00:20:49,560 --> 00:20:52,399 Speaker 3: that is what we're investing in DOE and not just 336 00:20:52,440 --> 00:20:54,919 Speaker 3: our office, but our EA is part of the Office 337 00:20:54,960 --> 00:20:57,960 Speaker 3: of Science and eer E, Energy Efficiency and Renewable Energy, 338 00:20:58,400 --> 00:21:04,240 Speaker 3: but our four offices of together to invest our base 339 00:21:04,240 --> 00:21:08,120 Speaker 3: appropriations across R and D to be able to get 340 00:21:08,200 --> 00:21:12,120 Speaker 3: to first of a kind demonstrations. So in that space, 341 00:21:12,480 --> 00:21:16,239 Speaker 3: we are estimating that if we invest and get to 342 00:21:16,320 --> 00:21:19,800 Speaker 3: the scale of millions and tons of removal per year. 343 00:21:20,160 --> 00:21:23,919 Speaker 3: Once we hit millions of tons per year removals, we 344 00:21:23,960 --> 00:21:25,960 Speaker 3: will get down that cost curve with a target of 345 00:21:25,960 --> 00:21:29,320 Speaker 3: one hundred dollars per ton. But to be honest, we 346 00:21:29,359 --> 00:21:32,280 Speaker 3: don't know that until we build you know, more thousands 347 00:21:32,280 --> 00:21:34,760 Speaker 3: of tons of removal. You know, that's where we're at today. 348 00:21:35,000 --> 00:21:37,680 Speaker 3: We need to get three more zeros in. We need 349 00:21:37,720 --> 00:21:40,120 Speaker 3: to get to millions, and I think at that millions, 350 00:21:40,440 --> 00:21:43,399 Speaker 3: once we're actually operating that facility and we are transparent 351 00:21:43,480 --> 00:21:47,399 Speaker 3: and true about the cost, we'll learn from that experience. 352 00:21:47,520 --> 00:21:50,120 Speaker 3: Right If it's six hundred dollars a ton, if it's 353 00:21:50,359 --> 00:21:53,440 Speaker 3: three hundred dollars a ton, and then the idea, though, 354 00:21:53,560 --> 00:21:56,720 Speaker 3: is to not just stop there. The idea is to 355 00:21:56,840 --> 00:22:02,159 Speaker 3: usher a new generation of direct dere capture technologies to 356 00:22:02,240 --> 00:22:06,119 Speaker 3: be able to be on the pipeline of more demonstrations. 357 00:22:06,400 --> 00:22:09,160 Speaker 3: It may not be that one, right, that first one 358 00:22:09,160 --> 00:22:10,000 Speaker 3: that they all look like. 359 00:22:11,320 --> 00:22:14,160 Speaker 1: There are a lot of things in net zero scenario 360 00:22:14,280 --> 00:22:16,560 Speaker 1: that we have to think about, and we can't always 361 00:22:16,600 --> 00:22:18,720 Speaker 1: have faith in all those things. We can't have faith 362 00:22:18,760 --> 00:22:22,120 Speaker 1: in politics, it may swing here or there. We can't 363 00:22:22,160 --> 00:22:25,439 Speaker 1: have faith in economics and finance, it may swing here 364 00:22:25,520 --> 00:22:28,240 Speaker 1: or there. Technology is one that we can have a 365 00:22:28,240 --> 00:22:30,480 Speaker 1: little more faith in because we understand the science, we 366 00:22:30,520 --> 00:22:32,960 Speaker 1: know some of the history, et cetera. But say we 367 00:22:33,119 --> 00:22:37,040 Speaker 1: don't reach the one hundred dollars per ton target number, 368 00:22:38,040 --> 00:22:39,640 Speaker 1: what happens to carbon removal? Then? 369 00:22:40,080 --> 00:22:42,720 Speaker 3: I think it depends too on what are the other 370 00:22:42,800 --> 00:22:46,000 Speaker 3: options that are cheaper. We talked about what truly hard 371 00:22:46,000 --> 00:22:49,040 Speaker 3: to decarbonize means. So when we get to the point 372 00:22:49,040 --> 00:22:51,680 Speaker 3: we cross that, and we'll call it a finish line, 373 00:22:51,680 --> 00:22:54,679 Speaker 3: it's more of like a water station stop or something 374 00:22:54,800 --> 00:22:57,240 Speaker 3: like when we get there at that millions of tons 375 00:22:58,000 --> 00:23:00,119 Speaker 3: of removal, because we still need three more zeros to 376 00:23:00,119 --> 00:23:01,880 Speaker 3: get to a billion or a gig a ton, Right, 377 00:23:01,960 --> 00:23:04,800 Speaker 3: So it's like, once we get there, if we're only 378 00:23:04,880 --> 00:23:09,000 Speaker 3: say at millions of tons of removal, and we haven't 379 00:23:09,040 --> 00:23:12,080 Speaker 3: hit one hundred dollars mark, and we look at what 380 00:23:12,200 --> 00:23:16,960 Speaker 3: we're trying to counterbalance, we might have to need more 381 00:23:17,040 --> 00:23:21,440 Speaker 3: policy to further incentivize direct air capture. I don't think 382 00:23:21,440 --> 00:23:23,800 Speaker 3: it's the policy that's going to get us to the 383 00:23:23,840 --> 00:23:26,480 Speaker 3: finish line. I think it's the policy that's going to 384 00:23:26,640 --> 00:23:29,160 Speaker 3: probably get us to the millions of tons of removal. 385 00:23:29,800 --> 00:23:32,119 Speaker 1: And that sort of speaks to the importance of having 386 00:23:32,119 --> 00:23:35,400 Speaker 1: a portfolio approach to try and tackle this problem. That 387 00:23:35,440 --> 00:23:38,359 Speaker 1: you're not betting on one technology or one horse or 388 00:23:38,400 --> 00:23:41,960 Speaker 1: even one company do get us there. Now, if you 389 00:23:42,440 --> 00:23:45,760 Speaker 1: were to think about the criticisms that come your way 390 00:23:46,600 --> 00:23:49,080 Speaker 1: for doing the work that you're doing, what do you 391 00:23:49,119 --> 00:23:53,119 Speaker 1: think is the biggest criticism of your own work? Maybe 392 00:23:53,160 --> 00:23:55,719 Speaker 1: an unreasonable one and maybe a reasonable one. 393 00:23:56,320 --> 00:24:00,920 Speaker 3: Yeah, that's a great question. I do feel right now 394 00:24:01,400 --> 00:24:05,320 Speaker 3: a lot of criticisms in this space, in part because 395 00:24:05,359 --> 00:24:08,800 Speaker 3: maybe of the version one point zero of what carbon 396 00:24:08,840 --> 00:24:12,480 Speaker 3: management look like. And I think we have so many 397 00:24:12,520 --> 00:24:18,760 Speaker 3: solutions that we are leaning on fossil energy companies to 398 00:24:19,600 --> 00:24:22,119 Speaker 3: be there with us as kind of part of the solution, 399 00:24:22,320 --> 00:24:24,840 Speaker 3: but at the same time they haven't always been good 400 00:24:24,840 --> 00:24:28,280 Speaker 3: stewards or good players on their word, and so it 401 00:24:28,320 --> 00:24:32,080 Speaker 3: makes it really difficult. I think what's going to be critical, though, 402 00:24:32,440 --> 00:24:36,280 Speaker 3: is working with that energy community and being able to 403 00:24:37,080 --> 00:24:40,399 Speaker 3: help that energy community be able to see a path. 404 00:24:40,920 --> 00:24:43,440 Speaker 3: When you look at the downstream management of CO two, 405 00:24:44,080 --> 00:24:47,040 Speaker 3: the only way of kind of disposing of CO two 406 00:24:47,480 --> 00:24:53,960 Speaker 3: that scales with our emissions is deep injection in geologic formations. 407 00:24:54,040 --> 00:24:58,439 Speaker 3: We can convert it to synthetic fuels and chemicals, we 408 00:24:58,480 --> 00:25:01,040 Speaker 3: can put it in our built environment and buildings and 409 00:25:01,080 --> 00:25:04,280 Speaker 3: things like that, and all those things will be wonderful, 410 00:25:04,320 --> 00:25:05,680 Speaker 3: but at the end of the day, it needs to 411 00:25:05,720 --> 00:25:09,439 Speaker 3: go deep underground where it came from. And the community 412 00:25:09,600 --> 00:25:14,240 Speaker 3: that the workforce that is skilled to do that are 413 00:25:14,280 --> 00:25:17,720 Speaker 3: the same ones that produced oil and gas and coal 414 00:25:17,760 --> 00:25:21,920 Speaker 3: to begin with. And so it's that workforce, it's that engineering. 415 00:25:22,400 --> 00:25:25,720 Speaker 3: And so you may have a direct air capture hub, 416 00:25:25,960 --> 00:25:29,720 Speaker 3: you may have a carbon capture project, and you say, 417 00:25:29,880 --> 00:25:34,240 Speaker 3: I'm not gonna partner with the fossil fuel industry. That's great, 418 00:25:34,359 --> 00:25:36,760 Speaker 3: but at the end of the day, to dispose of 419 00:25:36,800 --> 00:25:41,240 Speaker 3: that CO two in a meaningful way, you're gonna call 420 00:25:41,480 --> 00:25:44,439 Speaker 3: on the expertise. We can get to millions of tons, 421 00:25:44,840 --> 00:25:46,479 Speaker 3: but how are we going to get to gigatons? Are 422 00:25:46,520 --> 00:25:49,120 Speaker 3: we going to rely on taxpayer dollars again? Or maybe 423 00:25:49,200 --> 00:25:51,520 Speaker 3: we can get the energy companies to step up and 424 00:25:51,600 --> 00:25:54,359 Speaker 3: help us get to scale, because they've got the workforce, 425 00:25:54,400 --> 00:25:57,879 Speaker 3: they have the engineers, they have the expertise, and they 426 00:25:57,920 --> 00:25:59,119 Speaker 3: could make up that gap. 427 00:26:00,800 --> 00:26:04,840 Speaker 1: That was a great conversation. Covin capture is a complicated subject, 428 00:26:05,080 --> 00:26:07,040 Speaker 1: and so the work that you do at the Department 429 00:26:07,040 --> 00:26:11,440 Speaker 1: of Energy is enabling both clarity while it's pushing the technology. 430 00:26:11,600 --> 00:26:12,680 Speaker 1: So thank you for your time. 431 00:26:12,800 --> 00:26:13,159 Speaker 3: Thank you. 432 00:26:21,920 --> 00:26:26,119 Speaker 1: Carbon removal technologies sometimes get overhyped, so it's important to 433 00:26:26,160 --> 00:26:29,720 Speaker 1: remember that the first thing to do is to reduce emissions. 434 00:26:30,400 --> 00:26:32,960 Speaker 1: Thank you for listening to Zero.
