On the Chevy Bolt’s return, China’s rare earth crackdown, and Nestle’s spoiled climate push

Current conditions: A possible nor’easter is barreling toward New York City with this weekend with heavy rain, flooding, and winds of up to 50 miles per hour • While Hurricane Priscilla has weakened to a tropical storm, it’s still battering Baja California with winds of up to 70 miles per hour • A heatwave in Iran is raising temperatures so much that even elevations of more than 6,500 feet are nearly 90 degrees Fahrenheit.
The Bureau of Land Management has canceled Nevada’s largest solar megaproject, Esmeralda 7, Heatmap’s Jael Holzman scooped late Thursday. The sprawling network of panels and batteries in the state’s western desert was set to produce a gargantuan 6.2 gigawatts of power — equal to nearly all the power supplied to the southern part of the state by the state’s main public utility. At maximum output, the project could have churned out more power than the country’s largest nuclear plant, the nearly 5 gigawatts from Plant Vogtle’s four reactors in Georgia, and just under the nearly 7.1-gigawatt Grand Coulee hydroelectric dam in Washington, the nation’s most powerful electrical station. It would have been one of the largest solar projects in the world.
Backed by NextEra Energy, Invenergy, ConnectGen, and other renewables developers, the project was moving forward at what Jael called “a relatively smooth pace under the Biden administration, albeit with significant concerns raised by environmentalists about its impacts on wildlife and fauna.” The solar farm notched a rare procedural win in the early days of the Trump administration when the Bureau of Land Management advanced its draft environmental impact statement. When the environmental review came out, BLM said the record of decision would arrive in July. “But that never happened,” Jael wrote. Instead, as part of a deal with conservative harderliners in Congress to pass his tax megabill, Trump issued an executive order that, among other actions aimed at curtailing renewables development, directed the Department of the Interior to review its policies toward wind and solar. A series of departmental orders followed that effectively froze all permitting decisions for solar. Fast forward to today, when Esmeralda 7’s status on the BLM website was changed to “cancelled,” normally an indication that the developers pulled the plug.
The Coastal Virginia Offshore Wind project, a 2.6-gigawatt giant that’s nearly triple the size of the nation’s current largest operating seaborne wind farm, is just six months from coming online, its leadership said. In an August earnings call, Dominion Energy CEO Robert Blue said the project would start producing electricity in “early 2026.” But on Thursday, the company told Canary Media’s Clare Fieseler that “first power will occur in Q1 of next year,” and “we are still on schedule to complete by late 2026.” As of the end of last month, Dominion had installed all 176 turbine foundations.
Since returning to office, President Donald Trump has waged what Jael called a “total war on wind power,” halting work on projects that were nearly 80% complete and ordering a half dozen federal agencies to join the effort. But the industry has fought back. Two weeks ago, as I reported in this newsletter, a federal judge lifted the administration’s stop-work order. While Secretary of Energy Chris Wright last month brushed off the targeting of offshore wind as a “one-off complication,” the assault has alarmed even the administration's favored sectors of the energy industry. Earlier this week, Shell’s top executive raised the alarm over what she said could set a precedent that blows back to big oil in the future.

Elon Musk’s promise to deliver a Tesla for under $30,000 may — as I wrote here yesterday — remains unfulfilled, but one of his biggest rivals is bringing back its popular affordable electric vehicle. General Motors announced on Thursday that it’s rolling out a new line of Chevrolet Bolts in 2027, starting at $29,990 and later introducing a $28,995 model. “The Chevrolet Bolt was the industry’s first affordable mass-market, long-range EV and it commanded one of GM’s most loyal customer bases thanks to its price, versatility and practicality,” Scott Bell, Chevrolet’s global vice president, said in a statement. “After production ended, we heard our customer’s feedback and their love for this product. So the Bolt is coming back — by popular demand and better than ever — for a limited time.” When Chevy discontinued the Bolt in 2023, the car was popular but had some problems, Andrew Moseman wrote Thursday in Heatmap. And while the 2027 Bolt “is virtually indistinguishable from the old car,” he wrote, “what’s inside is a welcome leap forward.” Notably, the new Bolt’s lithium-ion-phosphate battery delivers a max range of 255 miles and can handle a 100% charge without risking long-term damage to the battery’s lifespan.
Though the $7,500 federal tax credit for electric vehicles expired last month, it’s morning in America for battery-powered car drivers. The U.S. is adding charging stations at a record clip, Bloomberg reported Thursday.
China’s Commerce Ministry announced a new edict Thursday requiring foreign suppliers to obtain approval from Beijing to export some products with certain rare earths if the metals account for 0.1% of the goods’ total value. Export applications for products with military uses “generally won’t be approved,” The Wall Street Journal reported, and licenses related to semiconductors or artificial intelligence will be granted on a case-by-case basis. “This is a very big deal,” Dean W. Bell, a senior fellow at the Foundation for American Innovation, wrote in a post on X. “China has asserted sweeping control over the entire global semiconductor supply chain, putting export license requirements on all rare earths used to manufacture advanced chips. If enforced aggressively, this policy could mean ‘lights out’ for the US AI boom, and likely lead to a recession/economic crisis in the US in the short term.” The new restrictions even apply to some lithium batteries and equipment used to make them.
Less than two years ago, Nestle formed an industry alliance with food giants Danone and Kraft Heinz to cut methane emissions from the dairy industry’s hundreds of thousands of suppliers. But last month, Nestle’s logo vanished from the initiative's website. On Wednesday, Bloomberg reported that the Swiss behemoth had abandoned the effort. “We have decided to discontinue our membership of the Dairy Methane Action Alliance,” a company spokesperson told the newswire.
The exit comes as sustainability executives, academics, and carbon-accounting experts spar over how to measure companies’ emissions in what Heatmap’s Emily Pontecorvo called an “obscure philosophical battle that could reshape the clean energy economy.” With the Trump administration phasing out wind and solar tax credits next year, Emily wrote, “voluntary action by companies will take on even greater importance in shaping the clean energy transition. While in theory, the Greenhouse Gas Protocol solely develops accounting rules and does not force companies to take any particular action, it’s undeniable that its decisions will set the stage for the next chapter of decarbonization.”
Increasingly extreme weather is driving up insurance costs all over the world, making homes almost impossible to underwrite in fire- or flood-prone places such as California or Florida where climate change is raising recovery costs. But Japan’s largest non-life insurer is taking a different approach than just canceling policies. As the Financial Times reported Thursday, Tokio Marine purchased Integrated Design & Engineering this year for roughly $642 million in a bid to offer the design consultancy’s services to “Japanese companies at risk of landslides, flooding, and natural disasters related to climate change” to upgrade facilities before destruction occurs.

Citrine Informatics has been applying machine learning to materials discovery for years. Now more advanced models are giving the tech a big boost.
When ChatGPT launched three years ago, it became abundantly clear that the power of generative artificial intelligence had the capacity to extend far beyond clever chatbots. Companies raised huge amounts of funding based on the idea that this new, more powerful AI could solve fundamental problems in science and medicine — design new proteins, discover breakthrough drugs, or invent new battery chemistries.
Citrine Informatics, however, has largely kept its head down. The startup was founded long before the AI boom, back in 2013, with the intention of using simple old machine learning to speed up the development of more advanced, sustainable materials. These days Citrine is doing the same thing, but with neural networks and transformers, the architecture that undergirds the generative AI revolution.
“The technology transition we’re going through right now is pretty massive,” Greg Mulholland, Citrine’s founder and CEO, told me. “But the core underlying goal of the company is still the same: help scientists identify the experiments that will get them to their material outcome as fast as possible.”
Rather than developing its own novel materials, Citrine operates on a software-as-a-service model, selling its platform to companies including Rolls-Royce, EMD Electronics, and chemicals giant LyondellBassell. While a SaaS product may be less glamorous than independently discovering a breakthrough compound that enables something like a room-temperature superconductor or an ultra-high-density battery, Citrine’s approach has already surfaced commercially relevant materials across a variety of sectors, while the boldest promises of generative AI for science remain distant dreams.
“You can think of it as science versus engineering,” Mulholland told me. “A lot of science is being done. Citrine is definitely the best in kind of taking it to the engineering level and coming to a product outcome rather than a scientific discovery.” Citrine has helped to develop everything from bio-based lotion ingredients to replace petrochemical-derived ones, to plastic-free detergents, to more sustainable fire-resistant home insulation, to PFAS-free food packaging, to UV-resistant paints.
On Wednesday, the company unveiled two new platform capabilities that it says will take its approach to the next level. The first is essentially an advanced LLM-powered filing system that organizes and structures unwieldy materials and chemicals datasets from across a company. The second is an AI framework informed by an extensive repository of chemistry, physics, and materials knowledge. It can ingest a company’s existing data, and, even if the overall volume is small, use it to create a list of hundreds of potential new materials optimized for factors such as sustainability, durability, weight, manufacturability, or whatever other outcomes the company is targeting.
The platform is neither purely generative nor purely predictive. Instead, Mulholland explained, companies can choose to use Citrine’s tools “in a more generative mode” if they want to explore broadly and open up the field of possible materials discoveries, or in a more “optimized” mode that stays narrowly focused on the parameters they set. “What we find is you need a healthy blend of the two,” he told me.
The novel compounds the model spits out still need to be synthesized and tested by humans. “What I tell people is, any plane made of materials designed exclusively by Citrine and never tested is not a plane I’m getting on,” Mulholland told me. The goal isn’t to achieve perfection right out of the lab, but rather to optimize the experiments companies end up having to do. “We still need to prove materials in the real world, because the real world will complicate it.”
Indeed it will. For one thing, while AI is capable of churning out millions of hypothetical materials — as a tool developed by Google DeepMind did in 2023 — materials scientists have since shown that many are just variants of known compounds, while others are unstable, unable to be synthesized, or otherwise irrelevant under real world conditions.
Such failures likely stem, in part, from another common limitation of AI models trained solely on publicly available materials and chemicals data: Academic research tends to report only successful outcomes, omitting data on what didn’t work and which compounds weren’t viable. That can lead models to be overly optimistic about the magnitude and potential of possible materials solutions and generate unrealistic “discoveries” that may have already been tested and rejected.
Because Citrine’s platform is deployed within customer organizations, it can largely sidestep this problem by tuning its model on niche, proprietary datasets. These datasets are small when compared with the vast public repositories used to train Citrine’s base model, but the granular information they contain about prior experiments — both successes and failures — has proven critical to bringing new discoveries to market.
While the holy grail for materials science may be a model trained on all the world’s relevant data — public and private, positive and negative — at this point that’s just a fantasy, one of Citrine’s investors, Mark Cupta of Prelude Ventures, told me over email. “It’s hard to get buy-in from the entire material development world to make an open-source model that pulls in data from across the field.”
Citrine’s last raise, which Prelude co-led, came at the very beginning of 2023, as the AI wave was still gathering momentum. But Mulholland said there’s no rush to raise additional capital — in fact, he expects Citrine to turn a profit in the next year or so.
That milestone would strongly validate the company’s strategy, which banks on steady revenue from its subscription-based model to compensate for the fact that it doesn’t own the intellectual property for the materials it helps develop. While Mulholland told me that many players in this space are trying to “invent new materials and patent them and try to sell them like drugs,” Citrine is able to “invent things much more quickly, in a more realistic way than the pie in the sky, hoping for a Nobel Prize [approach].”
Citrine is also careful to assure that its model accounts for real world constraints such as regulations and production bottlenecks. Say a materials company is creating an aluminum alloy for an automaker, Mulholland explained — it might be critical to stay within certain elemental bounds. If the company were to add in novel elements, the automaker would likely want to put its new compound through a rigorous testing process, which would be annoying if it’s looking to get to market as quickly as possible. Better, perhaps, to tinker around the edges of what’s well understood.
In fact, Mulholland told me it’s often these marginal improvements that initially bring customers into the fold, convincing them that this whole AI-for-materials thing is more than just hype. “The first project is almost always like, make the adhesive a little bit stickier — because that’s a good way to prove to these skeptical scientists that AI is real and here to stay,” he said. “And then they use that as justification to invest further and further back in their product development pipeline, such that their whole product portfolio can be optimized by AI.”
Overall, the company says that its new framework can speed up materials development by 80%. So while Mulholland and Citrine overall may not be going for the Nobel in Chemistry, don’t doubt for a second that they’re trying to lead a fundamental shift in the way consumer products are designed.
“I’m as bullish as I can possibly be on AI in science,” Mulholland told me. “It is the most exciting time to be a scientist since Newton. But I think that the gap between scientific discovery and realized business is much larger than a lot of AI folks think.”
Plus more insights from Heatmap’s latest event Washington, D.C.
At Heatmap’s event, “Supercharging the Grid,” two members of the House of Representatives — a California Democrat and a Colorado Republican — talked about their shared political fight to loosen implementation of the National Environmental Policy Act to accelerate energy deployment.
Representatives Gabe Evans and Scott Peters spoke with Heatmap’s Robinson Meyer at the Washington, D.C., gathering about how permitting reform is faring in Congress.
“The game in the 1970s was to stop things, but if you’re a climate activist now, the game is to build things,” said Peters, who worked as an environmental lawyer for many years. “My proposal is, get out of the way of everything and we win. Renewables win. And NEPA is a big delay.”
NEPA requires that the federal government review the environmental implications of its actions before finalizing them, permitting decisions included. The 50-year-old environmental law has already undergone several rounds of reform, including efforts under both Presidents Biden and Trump to remove redundancies and reduce the size and scope of environmental analyses conducted under the law. But bottlenecks remain — completing the highest level of review under the law still takes four-and-a-half years, on average. Just before Thanksgiving, the House Committee on Natural Resources advanced the SPEED Act, which aims to ease that congestion by creating shortcuts for environmental reviews, limiting judicial review of the final assessments, and preventing current and future presidents from arbitrarily rescinding permits, subject to certain exceptions.
Evans framed the problem in terms of keeping up with countries like China on building energy infrastructure. “I’ve seen how other parts of the world produce energy, produce other things,” said Evans. “We build things cleaner and more responsibly here than really anywhere else on the planet.”
Both representatives agreed that the SPEED Act on its own wouldn’t solve all the United States’ energy issues. Peters hinted at other permitting legislation in the works.
“We want to take that SPEED Act on the NEPA reform and marry it with specific energy reforms, including transmission,” said Peters.
Next, Neil Chatterjee, a former Commissioner of the Federal Energy Regulatory Commission, explained to Rob another regulatory change that could affect the pace of energy infrastructure buildout: a directive from the Department of Energy to FERC to come up with better ways of connecting large new sources of electricity demand — i.e. data centers — to the grid.
“This issue is all about data centers and AI, but it goes beyond data centers and AI,” said Chatterjee. “It deals with all of the pressures that we are seeing in terms of demand from the grid from cloud computing and quantum computing, streaming services, crypto and Bitcoin mining, reshoring of manufacturing, vehicle electrification, building electrification, semiconductor manufacturing.”
Chatterjee argued that navigating load growth to support AI data centers should be a bipartisan issue. He expressed hope that AI could help bridge the partisan divide.
“We have become mired in this politics of, if you’re for fossil fuels, you are of the political right. If you’re for clean energy and climate solutions, you’re the political left,” he said. “I think AI is going to be the thing that busts us out of it.”
Updating and upgrading the grid to accommodate data centers has grown more urgent in the face of drastically rising electricity demand projections.
Marsden Hanna, Google’s head of energy and dust policy, told Heatmap’s Jillian Goodman that the company is eyeing transmission technology to connect its own data centers to the grid faster.
“We looked at advanced transition technologies, high performance conductors,” said Hanna. “We see that really as just an incredibly rapid, no-brainer opportunity.”
Advanced transmission technologies, otherwise known as ATTs, could help expand the existing grid’s capacity, freeing up space for some of the load growth that economy-wide electrification and data centers would require. Building new transmission lines, however, requires permits — the central issue that panelists kept returning to throughout the event.
Devin Hartman, director of energy and environmental policy at the R Street Institute, told Jillian that investors are nervous that already-approved permits could be revoked — something the solar industry has struggled with under the Trump administration.
“Half the battle now is not just getting the permits on time and getting projects to break ground,” said Hartman. “It’s also permitting permanence.”
This event was made possible by the American Council on Renewable Energy’s Macro Grid Initiative.
On gas turbine backorders, Europe’s not-so-green deal, and Iranian cloud seeding
Current conditions: Up to 10 inches of rain in the Cascades threatens mudslides, particularly in areas where wildfires denuded the landscape of the trees whose roots once held soil in place • South Africa has issued extreme fire warnings for Northern Cape, Western Cape, and Eastern Cape • Still roiling from last week’s failed attempt at a military coup, Benin’s capital of Cotonou is in the midst of a streak of days with temperatures over 90 degrees Fahrenheit and no end in sight.

Exxon Mobil Corp. plans to cut planned spending on low-carbon projects by a third, joining much of the rest of its industry in refocusing on fossil fuels. The nation’s largest oil producer said it would increase its earnings and cash flow by $5 billion by 2030. The company projected earnings to grow by 13% each year without any increase in capital spending. But the upstream division, which includes exploration and production, is expected to bring in $14 billion in earnings growth compared to 2024. The key projects The Wall Street Journal listed in the Permian Basin, Guyana and at liquified natural gas sites would total $4 billion in earnings growth alone over the next five years. The announcement came a day before the Department of the Interior auctioned off $279 million of leases across 80 million acres of federal waters in the Gulf of Mexico.
Speaking of oil and water, early Wednesday U.S. armed forces seized an oil tanker off the coast of Venezuela in what The New York Times called “a dramatic escalation in President Trump’s pressure campaign against Nicolás Maduro.” When asked what would become of the vessel's oil, Trump said at the White House, “Well, we keep it, I guess.”
The Federal Reserve slashed its key benchmark interest rate for the third time this year. The 0.25 percentage point cut was meant to calibrate the borrowing costs to stay within a range between 3.5% and 3.75%. The 9-3 vote by the central bank’s board of governors amounted to what Wall Street calls a hawkish cut, a move to prop up a cooling labor market while signaling strong concerns about future downward adjustments that’s considered so rare CNBC previously questioned whether it could be real. But it’s good news for clean energy. As Heatmap’s Matthew Zeitlin wrote after the September rate cut, lower borrowing costs “may provide some relief to renewables developers and investors, who are especially sensitive to financing costs.” But it likely isn’t enough to wipe out the effects of Trump’s tariffs and tax credit phaseouts.
GE Vernova plans to increase its capacity to manufacture gas turbines by 20 gigawatts once assembly line expansions are completed in the middle of next year. But in a presentation to investors this week, the company said it’s already sold out of new gas turbines all the way through 2028, and has less than 10 gigawatts of equipment left to sell for 2029. It’s no wonder supersonic jet startups, as I wrote about in yesterday’s newsletter, are now eyeing a near-term windfall by getting into the gas turbine business.

The European Union will free more than 80% of the companies from environmental reporting rules under a deal struck this week. The agreement between EU institutions marks what Politico Europe called a “major legislative victory” for European Commission President Ursula von der Leyen, who has sought to make the bloc more economically self-sufficient by cutting red tape for business in her second term in office. The rollback is also a win for Trump, whose administration heavily criticized the EU’s green rules. It’s also a victory for the U.S. president’s far-right allies in Europe. The deal fractured the coalition that got the German politician reelected to the EU’s top job, forcing her center-right faction to team up with the far right to win enough votes for secure victory.
Ravaged by drought, Iran is carrying out cloud-seeding operations in a bid to increase rainfall amid what the Financial Times clocked as “the worst water crisis in six decades.” On Tuesday, Abbas Aliabadi, the energy minister, said the country had begun a fresh round of injecting crystals into clouds using planes, drones, and ground-based launchers. The country has even started developing drones specifically tailored to cloud seeding.
The effort comes just weeks after the Islamic Republic announced that it “no longer has a choice” but to move its capital city as ongoing strain on water supplies and land causes Tehran to sink by nearly one foot per year. As I wrote in this newsletter, Iranian President Masoud Pezeshkian called the situation a “catastrophe” and “a dark future.”
The end of suburban kids whiffing diesel exhaust in the back of stuffy, rumbling old yellow school buses is nigh. The battery-powered bus startup Highland Electric Fleets just raised $150 million in an equity round from Aiga Capital Partners to deploy its fleets of buses and trucks across the U.S., Axios reported. In a press release, the company said its vehicles would hit the streets by next year.
