Robinson Meyer:
[0:59] Hello, it’s Wednesday, April 15, and there’s big news in the small but extremely important world of carbon removal. Last week, Microsoft informed some partners and suppliers that it’s pausing its carbon removal purchases. I first reported the news here at Heatmap on Friday. Bloomberg and Carbon Herald have confirmed the story as well. And it’s a huge deal for the carbon removal industry. That is, the set of companies trying to develop technologies that can reduce or eliminate heat-trapping carbon dioxide from the atmosphere. Sometimes you’ll hear it get called CDR for carbon dioxide removal. And no matter what you call it, in recent years, Microsoft basically was the industry. Since 2020, it’s bought more than 70 million tons of carbon removal, which is 40 times more than any other organization or coalition has purchased. The CDR scientist Julio Friedmann told me that there are lots of tech companies out there whose whole business model was basically, we’re going to develop a CDR technology, and then we’ll sell to Microsoft. Well, now Microsoft won’t be buying any more, at least for the time being.
Robinson Meyer:
[1:59] I think it’s important to intervene here and say CDR is not a nice-to-have technology. The IPCC says we’ll need carbon removal to meet the Paris Agreement’s goals. And by one estimate, the world will need to be removing 7 billion to 9 billion tons of carbon a year by 2050 in order to maintain its Paris targets. Now, Microsoft, for its part, says its program isn’t totally over. Melanie Nakagawa, their chief sustainability officer, told me in a statement, quote, our carbon removal program has not ended. We continue to both build on and support our existing portfolio of nature-based and technology-based solutions. At times, we may adjust the pace or volume of our carbon removal procurement as we continue to refine our approach towards sustainability goals. Any adjustments we make are part of our disciplined approach and not a change in ambition, unquote. But even if just the pace and volume are changing, it’s still a big deal. We are going to need this technology, and we just lost its biggest buyer. So what comes next? Here to chat about it today is Jack Andreasen Cavanaugh. He’s the director of the Carbon Management Program at the Center on Global Energy Policy at Columbia University, and he’s the president of Carbon Middle Management Incorporated. He was previously policy manager for carbon management at Breakthrough Energy. Jack and I talk about the history of CDR, what Microsoft’s departure might mean, and what’s coming next for the industry. I’m Robinson Meyer, the founding executive editor of Heatap News, and it’s all coming up on Shift Key. Jack Cavanaugh, welcome to Shift Key.
Jack Andreasen Cavanaugh:
[3:26] Thanks for having me on, Rob. Good to see you.
Robinson Meyer:
[3:28] Good to see you. So let’s start here. Why was Microsoft such an important player in the carbon removal system?
Jack Andreasen Cavanaugh:
[3:35] Yeah, well, I think it’s important to do, you know, a little unearthing of the history of carbon removal, how we got to where we’re at today.
Jack Andreasen Cavanaugh:
[3:43] There was, you know, a lot of seminal work done in the 1990s, the early 2000s about this crazy thing called direct air capture, where you could remove CO2 from the ambient air.
Jack Andreasen Cavanaugh:
[3:54] And a lot of that was done by Klaus Lochner and David Keith, who have both founded different director capture companies, David Keith, carbon engineering, which was eventually sold to Occidental Petroleum. And then it was mostly R&D academic research. And then in 2019, Stripe, the payment processing company, announced $1 million for purchasing of carbon dioxide removal. And then in 2020, Microsoft announced their net negative by 2030 sustainability goal. And in 2022, that was followed up by the Frontier Fund, which was Stripe following on with a number of other partners, a $1 billion advanced market commitment. And so up until that point, what we think of today as carbon removal and the carbon removal market really didn’t exist. And so Microsoft was the first to get in and say, we are going to put relatively large capital outlays towards purchasing carbon removal alongside what Frontier did with the advanced market commitment and essentially kicked off a massive hype cycle for CDR that went across some government policy and certainly private investment.
Robinson Meyer:
[5:11] That history is super helpful. And also I feel like it is worth kind of hammering that at least when I started being a climate reporter, which was like 2016, 2017, 2015,
Robinson Meyer:
[5:23] carbon removal was seen as this purely science fictional technology. Like basically something we might need to develop down the line. There had been work on it done. It was a little taboo to talk about it because the sense was that talking about it would discourage the work of emissions reductions. And there was a sense that it would be really hard. And I mean, it is really hard, but there was a sense that it was like something to talk about in decades to come, but not something we were going to be talking about scaling in the next 10 years. And I do feel like the big milestone there, you know this, I’m just injecting it into the history, was the 1.5C report from the Intergovernmental Panel on Climate Change, which kind of said, hey, if the world wants to hit 1.5C or even 2C, first of all, it would be really bad for us to hit 1.5C. There’d be lots of near-term consequences. And of course, it’s pretty clear those are going to happen now. But there was a lot of energy around avoiding that. But also, if we want to not be at 1.5C by the end of the century, then the only way to do that is to know that we’re going to overshoot in the middle of the century and then draw down carbon at the end of the century. And that will require carbon removal. And so therefore, we need to start working on this technology now. And at least for me, that was the point as a reporter where it went from like, is this real? Should I be thinking about this? Like, does this matter? It seems like it would be a useful thing to have, but maybe there’s a reason nobody’s talking about it to like, oh, this is just like a tool that we are going to need to deal with climate change. And we need to start working on the tool now.
Jack Andreasen Cavanaugh:
[6:52] Yeah, absolutely. And, you know, not to, there’s a much longer history than I laid out. I mean, to your point on the IPCC report, my colleague at Columbia, Noah Deich, founded Carbon180 around the time of that report coming out, which is the first CDR-specific NGO. And there were all sorts of folks that were talking about thinking about building a lot of the frameworks in the federal programs that we have today and building the bedrock of scientific understanding and R&D that have become companies today. And so a lot more happened, but you’re totally right that that report really kicked, like brought carbon removal from, you know, the sort of fringes of climate discussions into a more focal point that we are going to need this at a relatively large scale to reach any climate goals, 1.5 or above.
Robinson Meyer:
[7:43] Yeah. So without that context preloaded then, what was the importance of Microsoft to the carbon removal market? Because it seemed to play a pretty essential role.
Jack Andreasen Cavanaugh:
[7:52] Yeah. So as you reported, I laid out in a piece that I published as well, Microsoft was somewhere around 80% of all voluntary carbon removal purchases in the market. And so just to be clear, voluntary means voluntary. This was done not because of any sort of compliance regulatory mechanism or some sort of incentive to be able to purchase. This was part of their sustainability plan. And being 80% of the market is a really interesting position to be in. And Microsoft, not just on the purchases that they made, the billions of dollars they have allocated towards carbon removal, they haven’t just done that, which in and of itself is an incredible thing to be able to get through all the intermachinations of a for-private business to be able to do this with discretionary spending. But they also then had the ability to sort of shape criteria, standardized contracts, all of these sorts of enabling pieces of financial and project infrastructure to be able to work, de-risk some aspects of the carbon removal market the voluntary market and so yeah they were quintessential in being able to buy build and then also bring in other buyers into the market to some extent now they tried very hard i’m sure they wished that more folks would have joined them but yeah if you’re 80% of the market you are the market essentially.
Robinson Meyer:
[9:20] It’s funny, I’ve been reporting out the consequences of this pullback from Microsoft or this pause or whatever we’re going to call it. And I think a number of folks in the industry have said, well, Microsoft did actually was amazing. I mean, they set this ambitious goal and they have met it and they’ve bought, I think, depending on how you count, 20 to 25 times more carbon removal than anyone else. It’s that that hasn’t been followed by other companies. The frontier companies are in second place, right? But it’s after that, no one has shown up to the same extent as Microsoft has. And that’s really significant. So I guess that naturally leads to the next question, which is how bad is it that Microsoft has gone? What does it mean for the carbon removal economy? And let’s bracket that like stuff should happen next. I mean, let’s bracket that, but let’s just kind of track fallout for now. How bad is it that Microsoft is now gone given that they were 80% of the market?
Jack Andreasen Cavanaugh:
[10:11] Yeah. So starting out, it’s obviously not good, right? There’s no way to sugarcoat losing potentially 80% of the market is good for an industry.
Jack Andreasen Cavanaugh:
[10:22] However, you look at broad sweeping trends across the voluntary carbon market across public policy, which I know that we’ll get to. And we were already in the downturn of the large scale venture capital and some project finance level investment that went into CDR. And so what you have is hundreds of companies that are doing some form of carbon dioxide removal. Very few of those have a credible ability to claim that they are going to remove the amount of tons that Microsoft was buying. Microsoft was buying relatively large tonnage amounts, right? The hundreds of thousands, potentially millions of tons per purchase. And so not that many companies had the ability to scale, were at the appropriate time in their technology to scale that big. And so it’s actually, relative to the entire CDR industry, a fairly small subset of companies that could even have considered Microsoft as a potential buyer. Now, that leaves the 20% of the market that tends to buy in slightly smaller amounts. And so you have all of those folks, including the potential large-scale providers, now fighting over 20% of the market. And fundamentally, what it will mean is just an acceleration of something that was going to happen anyway, which is consolidation and bankruptcies or dissolutions. This was always going to happen at this moment because we don’t have supportive policy.
Jack Andreasen Cavanaugh:
[11:49] And everyone in CDR knew it was in every conference, every conversation knew that this moment was going to happen. There was going to be a moment where Microsoft wasn’t going to buy the clip that they are anymore. And so you really could have had this story written for two years. And it was just like hit send when it occurred. And we’re just at that point right now.
Robinson Meyer:
[12:07] Something that’s come up in my reporting that I think is now kind of an interesting facet of the next step here is that because Microsoft was buying so much more than anyone else, there was no one else who was able to set prices with them. They were kind of setting the price and they were doing all the price exploration themselves as one firm, which is obviously suboptimal, let’s put it that way, and very tricky, I think, as a place to be in as a buyer. And I guess now there’ll be a lot more competition for buyers. And so maybe the price of carbon removal will fall. I don’t know. But one of the problems with no other buyer showing up is that Microsoft basically had to do all the price discovery itself. What are the next steps for carbon removal? It sounds like there is going to be a wave of bankruptcies to some degree. Maybe that’s a little inevitable. It’s a growing technology. But on the other hand, we’d like to retain the ability to continue to make advances in carbon removal technology. So like what should happen next across the market?
Jack Andreasen Cavanaugh:
[13:03] You’re absolutely right. There are going to be consolidations. There are going to be bankruptcies. The consolidations are going to increase the runway for the companies that will consolidate to try to hold on as long as they can. There’s an organization called Ctrl-S that Jason Hochman started up that is looking to retain some of the IP for some of these bankruptcies.
Robinson Meyer:
[13:22] My colleague, Emily Pontecorvo, wrote a story about it, which we’ll stick in the show notes.
Jack Andreasen Cavanaugh:
[13:26] Yeah, yeah. Yeah, and I think it’s an interesting model because there is an incredibly diverse set of technologies. Within every CDR pathway, there’s a hundred different DAC companies or something like that, and they all do something slightly different. And you could imagine a world in which there is incentivizing policy for carbon removal. That IP could be valuable to folks to be able to learn faster, to build quicker.
Jack Andreasen Cavanaugh:
[13:50] I also just want to take a brief note, just a moment to say, I’m like, what happens next is it is sort of incredible to me that there was a moment in time that there were folks at Microsoft, that got in with the C-suite, with the people that were allocating capital within the company and were able to carve out this program. That is amazing. This is voluntary discretionary spending at billions of dollars. And although the tech companies have free cash flow to be able to spend on this, having that same conversation today almost feels impossible, like going into, and Microsoft did have these conversations with a lot of other private companies about trying to spur folks into the market. And that’s sort of incredible. And so one pathway forward, I think that it’s been clear that sort of shut off is I don’t have a lot of confidence that there are going to be new private buyers at a meaningful amount. I just don’t think when you look at the broad fiscal reality of the world at the moment, that it just makes sense for any amount of discretionary spending to be spent on carbon removal, let alone many other climate technologies.
Robinson Meyer:
[14:57] And the key kind of elephant in the room here, right, is that a lot of the private spending on climate technologies, be it carbon removal or renewable construction and development or electric vehicle manufacturing, frankly, was coming from
Robinson Meyer:
[15:11] these big tech companies. I mean, Amazon is an investor in Rivian, right? And is it major source of offtake for Rivian to buy a lot of Rivian delivery vans? Apple and Google and Microsoft had these very aggressive renewable acquisition targets. And part of what’s happened over the past three years is that all the companies that were doing, basically directing some amount of free cash flow to climate investment, have become basically cash strapped light industrial companies that have to build as much physical infrastructure as they can and as much power generation infrastructure as they can. And every dollar matters much more than it did, say, two or three years ago. I think the exception would be Apple here. But for a while, we were able to kind of finance a lot of the climate ecosystem off the back of what was basically an employee perk because it was a very aggressive market for tech employees and they liked working at companies that had these big climate programs. And that is like fully over. The bull market for tech labor employment is over. The ability of these companies to finance climate tech is over. The willingness of them to finance climate tech as opposed to to dump another marginal dollar into data center development or AI model development is over. Like it’s all over.
Robinson Meyer:
[16:27] And that’s a major moment, not only for I mean, to some degree, carbon removal is like most illustrative version of it because it was the closest to like the gargoyle on the cathedral for Microsoft. The beautiful thing they could fund as a result of their incredible societal surplus, but like it’s over for a lot of different things.
Jack Andreasen Cavanaugh:
[16:45] Yeah. And, and like you said, this is just one story amongst many other stories
Jack Andreasen Cavanaugh:
[16:50] that could be written in, in a similar vein. And to your original question about where to go forward from now, You could have another surplus of what you just described come up and you, climate commitments could kick back up again. And we would just do this whole thing over again. We would run it back and we would be having this conversation, you know, five years from now or whenever that is. And the way to hedge against that from happening and to some extent stop it from happening is to have federal governments across the globe pass durable policy that either compels the regulation or incentivizes the deployment of carbon dioxide removal and that because carbon dioxide removal outside of the co-benefits of some pathways, which are fantastic, just removing carbon from the atmosphere for pure carbon sake. Is the tragedy of the commons in a single climate technology entity. Like this is something that will need federal support in the long run to some extent in a way that other climate technologies don’t. That’s true of most of the carbon management world, but it is uniquely true of CDR.
Robinson Meyer:
[18:01] But it’s a form of waste management. Trash and recycling also require ongoing government support. Now, at this point, it tends to come from the state and local level. But governments still pay to handle waste. That’s part of what we expect governments to do. It’s just that this waste happens to be in the atmosphere and requires a particularly high form of technology to dispel.
Jack Andreasen Cavanaugh:
[18:23] Yeah, it’s a very costly trash pickup service. And it also is contingent upon people caring about the trash. There is a relatively large constituency around the world that is unconvinced that the trash is an issue. And that is the big challenge.
Robinson Meyer:
[18:40] Yeah, agnostic on the trash. You know, historically, Congress has been quite supportive of carbon removal technology, but the current administration has not been as supportive. What has been funded in terms of federal policy that could potentially begin to pick up the pieces here? And then what should be funded with a more constructive Congress, a more constructive administration? What kind of policy should we eventually hope to see that could fight off some of this carbon removal wave of consolidation and bankruptcies?
Jack Andreasen Cavanaugh:
[19:11] Well, there was some appropriations money that was put into place for carbon removal R&D, and that is valuable and it’s good to be able to work on the research and development to help scale these technologies. But in terms of actual federal funds that have been spent, the DAC hubs program at the end of the Biden administration issued two $50 million grants to the large DAC hubs. That is the full extent to which is the monies that have been spent on the $3.5 billion DAC hubs program. The rest of that money is sitting at DOE, going through some internal review or whatever is happening at the moment with the DAC hubs program.
Robinson Meyer:
[19:53] It’s like the movie Brazil, presumably.
Jack Andreasen Cavanaugh:
[19:55] Yes, exactly. The purchase prize is in a similar position, paused indefinitely, unclear of if or when that money will be spent. And the only existing policy that incentivizes carbon removal to any extent only incentivizes direct air capture and BECCS which is the 45Q tax credit you.
Robinson Meyer:
[20:14] Get 180 dollars a ton if you remove a ton of carbon from the atmosphere
Jack Andreasen Cavanaugh:
[20:17] Yeah with direct air capture one yeah and and with BECCS you would get 85 dollars a ton and that you know to count that as CDR there are some LCAs in terms of what biomass feedstocks you’re using into the process.
Robinson Meyer:
[20:32] But remind listeners what BECCS is.
Jack Andreasen Cavanaugh:
[20:34] Oh, bioenergy with CCS. So you burn some sort of biomass feedstock and capture that CO2 at a point source. So you could imagine heat and power being used to create pulp and paper, and then you capture the CO2. And that receives $85 a ton because it’s point source capture. But even then, $85 a ton is not enough to reach final investment decision on the BEX facility. and $180 a ton isn’t enough to reach profitability for a DAC company. And so you still have to make up the delta to profitability and that is in the voluntary market, which as we discussed, has greatly retracted and the appetite for relatively expensive DAC credits is pretty low right now considering the fiscal situation of it all. And so.
Jack Andreasen Cavanaugh:
[21:18] If I’m looking at it right now from the U.S. federal government, there’s basically very little to no current outlays for carbon removal. Going forward, there was a specific carbon removal tax credit that was introduced that had increased dollar amounts for various forms of CDR, basically functionally all forms of CDR. There has been discussions of in carbon border adjustment mechanism that Europe put in, Senator Cassidy as well as Senator Whitehouse each have a sort of trade policy as a sort of response to the carbon border adjustment mechanism. And that could include compliance pathways for carbon removal. I think it is important that, Because the cost of carbon removal is so high and because the political winds of the United States have been shifting very rapidly back and forth in terms of how political parties view climate and execute on climate policies or not execute on climate policies, that you have as many bites of the apple as you can. And CDR is embedded into as many policies as you can get it into, whether it’s trade policies, whether it’s tax credits, whether it’s direct procurement, or even farming smart programs for soil carbon sequestration. And there’s all sorts of different policy and regulatory opportunities. It’s just a matter of which ones the politics and the finances will allow.
Robinson Meyer:
[22:41] What’s happening around the world? Are other countries beginning to put money toward carbon removal that are not the U.S.?
Jack Andreasen Cavanaugh:
[22:47] Yeah, Canada has a $10 million procurement program, which is the first procurement program of its kind that’s ever been put into place. They’re soliciting proposals for that now. I mean, $10 million admittedly isn’t a lot, but it’s something. And you build on policies like this, and so it’s a good first start.
Robinson Meyer:
[23:04] $10 million Canadian.
Jack Andreasen Cavanaugh:
[23:06] Yeah, that is true. $10 million Canadian. And then in Europe, Europe is integrating carbon removals into their emissions trading system. And that the final rules on that will happen in the next couple of years, which leaves a gap in terms of when that market will be accessible. Japan has compliance pathways in their domestic ETS for carbon removal. But in terms of pure policy market incentives that actually will get carbon dioxide removal projects built in the real world, incredibly limited in the next three to five years or whenever Europe integrates them, if not all else will equal nothing else goes forward, Europe will become the largest carbon removal market in the world. Until that happens, there is nothing in the near term that is moving forward.
Robinson Meyer:
[23:52] Is there anything happening in China? Because often the story of these climate tech investments is that the West starts them up, gets bored, allows all this IP to die on the vine. I think this is part of the idea of Ctrl-S. And then basically all the IP goes to China and China decides this is a frontier technology that it wants to invest in. And lo and behold, five years later is the best at it in the world. Like, is that happening right now with carbon removal, or is this not a field that China has indicated much interest in so far?
Jack Andreasen Cavanaugh:
[24:20] It’s tough to find data or information on carbon removal in China, although Tencent? Yeah. They announced some prizes structurally similar to sort of the Musk XPRIZE that $100 million for carbon removal. And there have been some reports of direct or capture R&D projects that have been built. But in my view, this is structurally different from China than any of the other things that they’ve done relative to the climate technologies that they’ve developed. Because again, you produce an EV, you produce a solar panel, you produce a battery, there’s a consumer that gains something valuable to them, whether it’s power from a solar panel or a battery, right? Power your car to help with the backup power on your house or an EV that is great and has cool features and is a, you know, a computer, but that’s not the same for carbon removal. And so like even totally China or like you look other places like the Gulf that Climeworks partnered with Saudi Arabia and obviously the Gulf countries are highly invested in a number of different technologies and have at least on balance sheet the money to be able to put towards this. But again, what is the value proposition for them to invest heavily in this industry when nowhere else around the world is?
Robinson Meyer:
[25:32] I mean, I think if also if you think about Chinese energy policy flows from a triangle of concern about conventional air pollution, you know, like PM2.5, energy security and wanting to stay at the frontier of technological development is really only that last point that would drive them
Robinson Meyer:
[25:48] to invest in carbon removal. At what point will the Chinese energy policy triangle become a diamond and we’ll see China make concerted investments focused not only on kind of playing up the climate benefits of its existing supply side investments, but affirmatively making supply side investments to advance international climate agenda. At that point, maybe we’ll see it invest in carbon removal. But until then, it doesn’t really fit into the existing Chinese paradigm.
Jack Andreasen Cavanaugh:
[26:13] There are a number of CDR pathways that have really interesting co-benefits associated with them that have a clearer way to scale than something like direct air capture, unless you’re using for enhanced soil recovery, which is possible, even then still expensive. But you look at things like enhanced rock weathering and the potential to increase yields for crops, as well as decrease the need for fertilizer. You can imagine there are ocean health benefits associated with some forms of ocean CDR. And so in that way, I think that there is an opportunity, and you are currently seeing this amongst the CDR pathways, that they are finding ways, like all climate tech is at the moment, to highlight everything but the climate value associated with their technology. And this was a bit of a doomy and gloomy pod, but I think that that is a very near-term pathway that a market has a value associated with these things, and it’s not a voluntary one on carbon.
Robinson Meyer:
[27:14] Well, we’re going to have to leave it there, but you and I know that at some point you’re going to come back on Shift Key to talk about another favorite topic of ours, which is how to dress for 1.5C. And we’ll have to talk about many other developments as well. But Jack Havanaugh, thank you so much for joining us on Shift Key. It was great to have you.
Jack Andreasen Cavanaugh:
[27:32] Thanks for having me on, Rob.
Robinson Meyer:
[27:38] And that will do it for us on Shift Key today. We’ll be back soon with another episode of Shift Key. Until then, if you love this show, if you hated it, if you had lots of thoughts, you can find me on X, Bluesky, or LinkedIn at Robinson Meyer. Stick around after the credits. We have a great message from our sponsor for this week, Lunar Energy, that I’m very excited about. Until then, Shift Key is a production of Heatmap News. Our editors are Jillian Goodman and Nico Lauricella. Multimedia Editing and Audio Engineering is by Jacob Lambert and by Nick Woodbury. Our music is by Adam Kromelow. Thanks so much for listening. We’ll see you real soon.
Mike Munsell:
[28:16] Hi, my name is Mike Munsell, and I’m the Vice President of Partnerships with Heatmap. For the last two episodes, I chatted with Lunar Energy’s Sam Weavers about solar, batteries, and utility rate design. Today, we dive into virtual power plants and international markets.
Sam Wevers:
[28:30] My name is Sam Wevers, and I’m Director of Product at Lunar Energy.
Mike Munsell:
[28:35] I know we’ve been talking a lot about VPPs. It seems like every company or even a research firm has a different definition of a virtual power plant. How does Lunar define a VPP?
Sam Wevers:
[28:47] I’ve certainly come across this myself. You can get right into the weeds of defining what a VPP is. But, I mean, to me, it’s really just connecting distributed assets together with software and controlling them in smart ways so that those assets deliver value to the grid and homes get paid for that sort of service in return. A VPP turns thousands of disparate homes into something that can look like a power plant to the grid, except it’s a power plant that can be segmented and provide very locational and temporal services to the grid, or it can be grouped together at sort of the top level to provide bulk level power when measured at sort of that transmission or sort of ISO level. That’s probably my definition of a VPP.
Mike Munsell:
[29:31] Do other countries, other markets have VPPs or VPP-like structures?
Sam Wevers:
[29:36] Yeah, for sure. I mean, this is something that’s been emerging in Europe and in Australia in particular for a good 10 years or so. It’s also worth flagging that when I talk about VPPs, I’m in the main talking about VPPs for residential assets. VPPs have been providing demand response services with arc furnaces and large industrial loads for some time.
Sam Wevers:
[29:58] And we are now in a world where it’s not just big factories and manufacturing processes that can provide flexible demand to the grid, but also thousands and thousands of homes. Lots of the Nordic countries have residential assets providing grid frequency services. In the U.K., residential assets can be traded by independent aggregators in markets that are used to balance the grid after the wholesale market closes. And Australia has, you know, a really active and competitive market for residential VPP services.
Mike Munsell:
[30:29] And I know most Shift Key listeners are based in the U.S., but what can the U.S. learn from power markets of other countries?
Sam Wevers:
[30:37] One point is the same problem has been addressed in lots of different ways in different markets, whether that’s more on the rate design side or more on the VPP sort of program design side. One common trend that we talked about earlier is certainly this idea that as there is a shift away from feed-in tariffs in other markets for solar, which is akin to net metering, so really generous solar compensation, that ushered in a big deployment of batteries. There are over a million residential batteries installed in Japan, and they were installed to maximize the value of customers’ solar and also to provide outage protection. It’s a big reason why Lunar provides and has provided software services in Japan with our Gridshare platform for many years now, connecting to residential assets to optimize them daily against time of use rates.
Sam Wevers:
[31:28] I think the other key learnings probably go to exposure of price signals to customers like Octopus Agile in the U.K., all those time of use rates in Japan, and the automated load-shaping effects that these sort of rate shapes can have. The other one probably to flag is 10 years ago in the UK, it used to be that you couldn’t really play residential assets in these sort of wholesale level markets. The markets were very much designed around big minimum clip sizes and sort of performance standards that were very tailored to existing gas turbines and the like. But over time, National Grid over there in the UK and others has done a bunch of work to adjust those market rules to allow VPPs of residential assets to start to participate in new services. And they are participating in those services. They’re providing value to the grid and to customers and millions of pounds a year are getting paid out on a purely market basis. It’s not a subsidy-based thing. It’s just markets being designed to allow the value of these assets to be recognized. But I would also say that the scale of VPP programs in the USA is remarkable.
Sam Wevers:
[32:40] Last year in the DSGS program, I think the Brattle Group put out a report. There was over 500 megawatts dispatched in one dispatch last year and you know one needn’t start with the most complex market structure but the core goal should be the same right which is recognize the true sort of physical and economic value of these residential assets and by doing so costs of managing the grid can reduce customers can save money and make money and more renewables can reliably be brought online.

Why local governments are getting an earful about “infrasound”
As the data center boom pressures counties, cities, and towns into fights over noise, the trickiest tone local officials are starting to hear complaints about is one they can’t even hear – a low-frequency rumble known as infrasound.
Infrasound is a phenomenon best described as sounds so low, they’re inaudible. These are the sorts of vibrations and pressure at the heart of earthquakes and volcanic activity. Infrasound can be anything from the waves shot out from a sonic boom or an explosion to very minute changes in air pressure around HVAC systems or refrigerators.
Knowing some of these facilities also have the capacity to produce significant audible noise, growing segments of the population’s more tech-skeptical and health-anxious corners are fretting some data centers could be making a lot of infrasound, too. The whizzing of so many large computational machines combined with cooling fans and other large devices creating so many new columns of air flow. Add onto that any rotational onsite power generation – think natural gas turbines, for example – and you get quite a lot of movement that could potentially produce what they say is infrasound.
Some of the virality of this chatter about infrasound and data centers comes from a video about infrasound created by audio engineer and researcher Benn Jordan. Currently sitting at more than 1 million views, this short YouTube film documents claims that some data centers are operating like “acoustic weapons” through infrasound and harming people. Andy Masley, an “effective altruist” writer, has become the chief critic of the Jordan video, getting into a back-and-forth that’s raised the issue to Internet discourse territory.
The Jordan-Masley infrasound debate is honestly a bit of a mess. So I want to be clear: I’m not going to get into the science of whether or not infrasound poses any kind of public health risk in this article. We can get to that later. It’s worth saying that this subject may need more study and that work is ongoing. Also, talking about infrasound at all can make you honestly sound a little wacky (see: this study blaming people seeing ghosts on infrasound). It might also remind you of another panic in the Electric Age: electromagnetic fields, also known as EMFs. Developers of transmission lines and solar projects have long had to deal with people worried about transmission lines and large electrical equipment potentially glowing with invisible, unhealthy radiation.
In late 2024, I wrote about how an RFK Jr. supporter worried about this form of electrical emission was helping lead the fight against a transmission line in New Jersey for offshore wind. Maybe that’s why it didn’t surprise me one bit when the Health and Human Services secretary himself told a U.S. Senate Committee last week that he was asking the Surgeon General’s office to “do either meta reviews” or “base studies” on noise pollution and EMF radiation from data centers “so we can better inform the American public.”
“There’s a range of injuries that are very, very well documented. They’re neurological – very, very grave neurological injuries, cancer risk,” Kennedy Jr. told the Senate Health, Education, Labor and Pensions Committee on April 22 in response to a request from Sen. Josh Hawley of Missouri to study the issue. “The risks, to me, are tremendous.”
There’s also the unfortunate reality that infrasound impacts have previously been a cudgel to slow down renewable energy deployment. Wind turbines create infrasound because of the subharmonic frequencies created when one turbine rotates at a slightly different pace than another, producing a slightly dissonant low frequency noise. Groups like the Heartland Institute proudly list this infrasound as one of the reasons wind energy “menaces man and nature.”
But regardless of merit, this concern is already impacting local government decisions around data center projects, much like how one Michigan county sought to restrict solar energy on the same basis.
In February Adrian Shelley, the Texas director for environmental group Public Citizen, implored the city of Red Rock to study changing their noise ordinance to take into account infrasound. “It has effects on sleep patterns, on stress, on cardiovascular health, and it is potentially a very serious concern,” Shelley said at a February 11 city council discussion on data center rules. “It will not be covered by the city’s noise ordinance, which only deals with audible sound.”
Earlier this month in Calvert County, Maryland, a volunteer for their environmental commission recently told the county government that infrasound needs to be factored into their future data center planning. “It will have significant impacts on our region and the Chesapeake and the Patuxent because infrasound isn’t stopped by walls,” commission member Janette Wysocki, a proud land conservationist, said at an April 15 hearing. “It will keep going, it will move through anything. It’s a very long wavelength. So we need to protect our ecosystem.” Wysocki implored the county to consider whether to adjust its noise regulations.
Around the same time, similar concerns were raised in Lebanon, a small city in east-central Pennsylvania. “It permeates through concrete walls, it permeates through the ground,” Thomas Dompier, an associate professor at Lebanon Valley College, said at an April 16 Lebanon County commission hearing on data centers.
Lastly, last week I explained how Loudon County wants to rethink its noise ordinance to deal with low-frequency “hums” from data centers – a concern echoing those who fret infrasound.
Ethan Bourdeau, executive director of standards at Quiet Parks Intentional and a career acoustician and building standards writer, told me that what makes data centers unique is the “constant drone” of noise that could potentially carry subharmonic frequencies. Bourdeau said cities or counties could possibly factor concerns about infrasound into noise ordinances to address those who are most concerned. One way they could do it is by changing how decibels are weighted in the government’s measurements. A-weighting decibel meters are a common form of sound measurement geared toward perceptible noise. Using different systems, like C-weighting or G-weighting, would avoid ways that A-weighting can filter out sub-hearing frequencies.
“These are reporting and weighting systems where a sound level meter taking background noise receives all the unweighted sound and then you apply all these filters afterwards, like an EQ curve,” Bourdeau said.
So I guess if those most concerned about infrasound have their way, a lot of country commissioners and local elected leaders will be heading to the mixing booth.
And more on the week’s top fights around project development.
1. King County, Washington – The Moss Landing battery backlash is alive and well more than a year after the fiery disaster, fomenting an opposition stampede that threatens to delay a massive energy storage project two dozen miles east of Seattle.
2. Prince Williams County, Virginia – It was a big week for data center troubles. Let’s start with Data Center Alley, which started to show cracks this week as data center developer Compass announced it was pulling out of the controversial Digital Gateway mega-project.
3. Washtenaw County, Michigan – Turning to Michigan, real estate firm Sansone abandoned plans to purchase land owned by Toyota to build a hyperscale data center campus after the local township instituted a 6-month moratoria.
4. Okeechobee County, Florida – The backlash to data centers is killing projects in deep-red Florida too, as this county’s commission decides to kill a 205-acre prospective data center campus led by a state college.

A conversation with Holly Jean Buck, author of a buzzy story about Bernie Sanders’ proposal for a national data center moratorium.
This week’s conversation is with Holly Jean Buck, an associate professor at the University of Buffalo and former official in the Energy Department’s Office of Fossil Energy and Carbon Management. Buck got into the thicket of the data center siting debate this past week after authoring a polemic epistemology of sorts in Jacobin arguing against a national data center ban. In the piece, she called a moratorium on AI data centers “a massive strategic blunder for the left, and we should think through the global justice implications and follow-on effects.” It argued that environmental and climate activists would be better suited not courting a left-right coalition that doesn’t seem to have shared goals in the long term.
Her article was praised by more Abundance-leaning thinkers like Matthew Yglesias and pilloried by some of the more influential people in the anti-data center organizing space, such as Ben Inskeep of Citizens Action Coalition of Indiana. So I wanted to chat with her about the discourse around her piece. She humbly obliged.
The following conversation was lightly edited for clarity.
So my first question is kind of a broad one and perhaps a suitable polemic to open with: are data center moratoria (bans) “slopulism”?
Haha, oh no. I don’t know if I have a working definition of that term.
“Slopulism” is colloquially known as low-effort or performative populism slop that is focused on emotional gratification and elite resentment instead of substantive policy.
I think, sometimes? Moratoria have been proposed at a lot of different levels in a lot of different forms. With the national moratorium, as written in the AI Data Center Moratorium Act [proposed by Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez], I thought from a rhetorical and textual standpoint it was a pretty amazing document. I just don’t think it’s a great policy proposal, so maybe that’s a little bit closer, but I don’t think people working on that theory of change would see it as slopulism. They’re thinking of this as a negotiating tactic and thinking, how do we leverage this moment and make it clear to the tech industry they don’t have social license?
I wouldn’t personally call it slopulism. I just don’t think it’ll work. I don’t think it's effective but I'm not big on labels.
Personally, I come down sort of where you’re at on the yes-and-no kind of tack. There’s definitely some vibes based stuff going on, which you address in your piece, but historically there’s a pretty long legacy of advocacy campaigns for, well, let’s ban this until we’ve finished regulating it.
You write part of why a moratoria push can be a dead end is that the right and left coalitions pushing to stop data centers have different interests on other issues and that it may not follow that stopping data centers will result in a clean energy buildout, or the social policies to address job displacement.
When you talk about the left-right coalition, help me understand what’s driving the opposition and why you think it’s happening the way it is?
I think there’s a lot of layers here. It’s pretty complex. It’s well established there are left-right coalitions. I don’t think we have a great body of social science research but I think that is a solid working assumption. So I think the people who are a part of this, it’s easy for them to come together and stop a thing that’s happening near them. But I don’t think they’re going to agree on how we build a decarbonized, resilient grid. The people in that coalition are going to have vastly different perspectives on whether we want to decarbonize, what measures are feasible and worth paying for to get there. Same thing when it comes to the thornier questions about AI governance. The solution set is just not something the members of that coalition are going to agree on.
So it feels maybe on the ground like this really cool moment about rising up against these big forces. It’s cool. I get it. I was actually very much on board with that a while ago. And my views on that have shifted. I don’t think it’s going to be productive unless it’s coupled with a lot of very real coalition building work I don’t see happening.
I’ve had conversations with environmental activists about that issue. I did a Q&A with someone from Public Citizen about this particular issue right after the national data center moratoria was introduced with Senator Sanders. I asked, do you have any concerns about pushing for a moratoria on new tech infrastructure when this tool is also used by those trying to stop solar, wind and batteries? Is there any concern that in some communities it’ll go from data centers to renewables?
I wondered reading your piece if this is part of what you’re getting at here, that this backlash doesn’t necessarily seem to be rooted as much in a transition away from fossil fuels or building lots of new renewable energy.
I think in the absence of systematic research, it’s one of these things where people can see it the way they want, through their own lens.
I’ve been following this in a few different places in the country, especially through online Facebook groups, and there is a noticeable overlap between some of those Facebook groups and the content and many of the anti-renewable groups I follow. Some of the themes remind me of this piece I wrote about para-environmentalism. There’s a lot of places where it dips into conspiracy and fears about new technology, electro-magnetic radiation, sorts of places where a data center is mundane but can take on creepy, supernatural overtones in some of these groups. Before I was studying para-environmentalism more generally I was thinking we really need this left-right coalition to rise up against these companies. Now I’m much more cautious about where it’ll lead.
I know Twitter isn’t real life, but the discourse around your work – those who have criticized it – are saying, why can’t we do both? Why can’t we go after the data center sector without potentially heading towards that form of politics you’re afraid of?
I don’t think it's the moratoria necessarily but the left-right blocking approach.
There’s a couple things I want to make discernments about. I want to make a discernment between people who want to stop a data center and a moratorium that’s more of a blanket, larger regional or national thing. I do think there are data centers being sited in really bad places, under really bad agreements. They shouldn’t move forward.
There’s bad data centers and there’s okay data centers and we need to be discerning between them. There’s also normal processes in this country for siting large facilities, whether they’re county level zoning commissions and something else.
But to your question of why can’t we do both, we could have a viable left-right anti-tech organizing that makes real demand for how we go about the lithium and AI age if people were investing in the social infrastructure necessary to make that happen. We’re very far from it because the framing of stopping a thing… We need people who are convening real conversations about what to do. I think they’re focused on stopping a thing.
I don’t know if they’re focused on whether we need universal basic income, a public wealth fund or something else, in a way that’s across the aisle. That would be a whole movement building infrastructure and it’s one we need if we’re going to decarbonize.
But that’s not what I am seeing – I’m seeing NGOs funded by wealthy and non-transparent donor-advised funds focused on some parts of the country and not others. We’re not getting to having those conversations happening or even having a shared media reality.
Can you go a bit deeper on how a situation where there is a national moratoria results in equity concerns? How are those less fortunate hurt by that?
There are three things I am concerned about. The first thing is that people who are better organized because they have more resources say we need a national moratoria which pushes development to regions with weaker organizing. Maybe they have weaker environmental and social regulations. I’m concerned about that because there’s a huge history of that happening across different regions and industries.
The second thing I am concerned about is driving up the cost of computation in ways that would make AI less affordable and accessible for people who may be able to use it for a variety of things. I realize that’s controversial for the segment of the population who thinks AI is useless but I think it’s tremendously valuable and I want a world where everybody has access to these capabilities and I think it’s made less likely by making computation less expensive.
The third thing, which I didn’t have room in my piece to address, is to what extent this moment is about the data centers. This is a new focus for the climate movement, which is understandable because there’s been a sideshift away from climate and the Trump administration has put everything in such a dire place that they need wins to hold on to. I’m worried about whether that displaces energy and funding away from other environmental issues. Are we taking space away from other priority areas? I’m not saying we know about those things but these are concerns we need to focus on. And if they’re not concerns, that’s good news. But we should think of them.
On that note, on the bigger question, do you believe artificial intelligence and these data centers are a net positive or a net negative for the effort to solve for climate change?
I think it’s too soon to say what the net effect will be and that net effect will be indirect. We can count the carbon emissions from these and say, great we have a whole new industrial sector to contend with among all these other industries we’re trying to decarbonize. And it’s bad from that point of view.
Then you have efficiencies that AI might discover. I have no clue about the extent of that.
Then you have AI impacting the information ecosystem, what they want to believe and what they want to do. Maybe the greatest impacts of AI will be it causes people to take climate more seriously. Or ways through social media that convince people it is a hoax.
It’s hard to measure all these factors and speculations against each other. So I have no idea what the net effect will be on climate and I don’t believe anyone who says they know what it’ll be at this point.
But the data centers – from your perspective, is this boom helping or hurting?
I think it’s definitely a setback. But if I look at the whole picture of climate change I think this is more tractable than some of the challenges we have with decarbonization. Number one, we know how to decarbonize data centers. It’s a lot harder than something like cement where we don’t know how to stop the emissions themselves. I think agriculture is really challenging to decarbonize – it’s mixed up in what people eat and land use. Data centers is a problem. But it seems tractable because of that.
We also have all these people working on this. All of these climate professionals who’ve pivoted to framing their work into being about AI. I think we have the knowledge and the personnel to do it. If I compare data centers to other parts of decarbonization, it’s not on the top of my list of things I’m worried about. But it is tough – we knew we had this many tonnes to deal with and now we’re adding things. It’s a challenge but I want to have perspective about the challenge.
Can I close on a fun question?
Sure.
What’s the last song you listened to?
Oh, gee. It was some terrible ‘80s song because my kind is really into that kind of music right now. The one that sticks out is “Sunglasses At Night,” which is always playing in the Buffalo airport.
