On geoengineering inching closer, Rivian writhes, and endless VC Summer

Current conditions: Tropical Storm Melissa is gathering enough strength to potentially reach Category 5 status as the cyclone tracks northward toward Florida and the Bahamas • Up to six storms are barreling toward the Pacific Northwest, threatening flooding from up to six inches of rain on Saturday • Parts of South Africa’s coast are roasting in temperatures above 109 degrees Fahrenheit.

The Department of the Interior unveiled a package of executive actions opening the Arctic National Wildlife Refuge to oil drilling and mining exploration, a controversial move that fulfills a decades-long ambition for industry. The decision marks what The New York Times described as “the latest twist in a long-running fight over the fate of the refuge’s coastal plain, an unspoiled expanse of 1.56 million acres that is believed to sit atop billions of barrels of oil but is also a critical habitat for polar bears, caribou, migratory birds, and other wildlife.” During his first term, in 2017, President Donald Trump signed a tax bill that required two oil and gas leases in the area, but the Biden administration later blocked those leases. “From day one, President Trump directed us to unlock Alaska’s energy and resource potential while honoring commitments to the state and local communities,” Secretary of the Interior Doug Burgum said in a statement. “By reopening the Coastal Plain and advancing key infrastructure, we are strengthening energy independence, creating jobs and supporting Alaska’s communities while driving economic growth across the state.”
The Trump administration has made industrializing the northernmost frontier state a key priority, approving a mining road though pristine forested lands and taking an equity stake for the federal government in the company aiming to extract minerals in the region. But the Environmental Protection Agency also yanked funding meant to help reinforce infrastructure in Alaska Native villages against warming-fueled floods, dismissing the money as left-wing ideologically driven “diversity, equity, and inclusion” spending, as I wrote in this newsletter. Those very communities were devastated by a typhoon earlier this month, displacing residents, with evacuees struggling to adjust to life in Alaska’s “concrete jungles,” the Northern Journal reported.
Heatmap’s Robinson Meyer has a big scoop this morning: Geoengineering startup Stardust Solutions is set to announce that it has raised $60 million in venture capital to develop the tools needed to artificially cool the planet by reflecting sunlight away from Earth. The company, led by a team of Israeli physicists, aims to spray aerosols into the atmosphere that will bounce energy from the sun back into space to balance out the effects of greenhouse gases. The technology is on track to be ready by the end of the decade. Lowercarbon Capital led the funding round, which is the company’s second, following a $15 million seed round in 2024. Rob’s story offers a measured assessment of the dangers of potentially geoengineering the atmosphere — and the threat of failing to do so when efforts to mitigate emissions are so far from where they need to be to preserve the climate norms in which humans evolved as a species. In a line that harkens to one of my favorite books, journalist Charles C. Mann’s environmental history of the global trade network that developed after Christopher Columbus’ arrival in the Americas called 1493, Rob notes that “the Earth has not been free of human influence for millennia,” and that “the world has over and over again been remade by human hands.”
“Stardust may not play the Prometheus here and bring this particular capability into humanity’s hands,” Rob writes. “But I have never been so certain that someone will try in our lifetimes. We find ourselves, once again, in the middle of things.”

Rivian, the maker of luxury electric trucks and SUVs, slashed more than 600 employees, representing nearly 4.5% of its roughly 15,000-person workforce, The Wall Street Journal reported Thursday. “These are not changes that were made lightly,” Rivian CEO RJ Scaringe said in an email to staff. “With the changing operating backdrop, we had to rethink how we are scaling our go-to-market functions.” The cuts were meant to help “profitably scale” the business as it prepares to launch its new R2 midsize SUV.
The move comes as electric automakers reel from the Trump administration’s elimination of the federal electric vehicle tax credit. Tesla, as I reported here yesterday, posted a nearly 40% drop in profits on Wednesday afternoon as the company lowered prices to keep costs to customers in line with what federal write-offs previously made possible. But as Andrew Moseman wrote in Heatmap, the lower prices came with stripped-down features.
The U.S. government has backed a new billion-dollar fund to invest in critical minerals along with the New York-based Orion Resource Partners and Abu Dhabi’s ADQ. The investment vehicle, dubbed the Orion Critical Mineral Consortium, was announced Thursday with support from the federal International Development Finance Corp. The funding totals more than $1.8 billion, Bloomberg reported.
This is just the Trump administration’s latest foray into mining. The Department of Defense took the largest stake earlier this year in MP Materials, the only active rare earths producer in the U.S. Since then, the administration has taken stakes in other critical minerals projects, and considered similar ownership positions in companies developing rare earths in Greenland.
VC Summer, the project to build Westinghouse’s state-of-the-art AP1000 reactor in South Carolina, became such a financial boondoggle, utility executives went to jail; The final defendant was sentenced just last year. Yet the project — widely mocked as a billion-dollar hole in the ground — may end up built after all. Utility Santee Cooper officially notified regulators this week that it plans to execute a contract to restart the project.
The announcement, part of what Heatmap’s Katie Brigham called the “nuclear dealmaking boom,” came the same day Canada’s government put up $2 billion to back a small modular reactor project in Bowmanville, Ontario. The progress north of America’s border on new reactor technologies has drawn attention from potential Democratic presidential candidates in the U.S. When New York City mayoral contender Zohran Mamdani expressed support for building new reactors in the state during this week’s debate, Arizona Senator Ruben Gallego — widely discussed as a possible White House seeker — responded to the news in a post on X: “I am all for Nuclear power in this country but it would be quicker and cheaper to buy into the Ontario plant being built and coming online by 2030.”
Mining giant Fortescue has made a breakthrough. In its latest earnings call with investors Thursday, the Australian giant said it planned to replace the trucks that carry its ore with electric alternatives. “We’re not doing this because we don’t think our total cost of ownership is going to be less,” Fortescue CEO Dino Otranto said in a statement. “Of course, we’re doing it because of that.”

How will America’s largest grid deal with the influx of electricity demand? It has until the end of the year to figure things out.
As America’s largest electricity market was deliberating over how to reform the interconnection of data centers, its independent market monitor threw a regulatory grenade into the mix. Just before the Thanksgiving holiday, the monitor filed a complaint with federal regulators saying that PJM Interconnection, which spans from Washington, D.C. to Ohio, should simply stop connecting new large data centers that it doesn’t have the capacity to serve reliably.
The complaint is just the latest development in a months-long debate involving the electricity market, power producers, utilities, elected officials, environmental activists, and consumer advocates over how to connect the deluge data centers in PJM’s 13-state territory without further increasing consumer electricity prices.
The system has been pushed into crisis by skyrocketing capacity auction prices, in which generators get paid to ensure they’re available when demand spikes. Those capacity auction prices have been fueled by high-octane demand projections, with PJM’s summer peak forecasted to jump from 154 gigawatts to 210 gigawatts in a decade. The 2034-35 forecast jumped 17% in just a year.
Over the past two two capacity auctions, actual and forecast data center growth has been responsible for over $16.6 billion in new costs, according to PJM’s independent market monitor; by contrast, the previous year’s auction generated a mere $2.2 billion. This has translated directly to higher retail electricity prices, including 20% increases in some parts of PJM’s territory, like New Jersey. It has also generated concerns about reliability of the whole system.
PJM wants to reform how data centers interconnect before the next capacity auction in June, but its members committee was unable to come to an agreement on a recommendation to PJM’s board during a November meeting. There were a dozen proposals, including one from the monitor; like all the others, it failed to garner the necessary two-thirds majority vote to be adopted formally.
So the monitor took its ideas straight to the top.
The market monitor’s complaint to the Federal Energy Regulatory Commission tracks closely with its plan at the November meeting. “PJM is currently proposing to allow the interconnection of large new data center loads that it cannot serve reliably and that will require load curtailments (black outs) of the data centers or of other customers at times. That result is not consistent with the basic responsibility of PJM to maintain a reliable grid and is therefore not just and reasonable,” the filing said. “Interconnecting large new data center loads when adequate capacity is not available is not providing reliable service.”
A PJM spokesperson told me, “We are still reviewing the complaint and will reserve comment at this time.”
But can its board still get a plan to FERC and avoid another blowout capacity auction?
“PJM is going to make a filing in December, no matter what. They have to get these rules in place to get to that next capacity auction in June,” Jon Gordon, policy director at Advanced Energy United, told me. “That’s what this has been about from the get-go. Nothing is going to stop PJM from filling something.”
The PJM spokesperson confirmed to me that “the board intends to act on large load additions to the system and is expected to provide an indication of its next steps over the next few weeks.” But especially after the membership’s failure to make a unified recommendation, what that proposal will be remains unclear. That has been a source of agita for the organizations’ many stakeholders.
“The absence of an affirmative advisory recommendation from the Members Committee creates uncertainty as to what reforms PJM’s Board of Managers may submit to the Federal Energy Regulatory Commission (FERC), and when stakeholders can expect that submission,” analysts at ClearView Energy Partners wrote in a note to clients. In spite of PJM’s commitments, they warned that the process could “slip into January,” which would give FERC just enough time to process the submission before the next capacity auction.
One idea did attract a majority vote from PJM’s membership: Southern Maryland Electric Cooperative’s, which largely echoed the PJM board’s own plan with some amendments. That suggestion called for a “Price Responsive Demand” system, in which electricity customers would agree to reduce their usage when wholesale prices spike. The system would be voluntary, unlike an earlier PJM proposal, which foresaw forcing large customers to curtail their power. “The load elects to not take on a capacity obligation, therefore does not pay for capacity, and is required to reduce demand during stressed system conditions,” PJM explained in an update. The Southern Maryland plan tweaks the PRD system to adjust its pricing mechanism. but largely aligns with what PJM’s staff put forward.
“There’s almost no real difference between the PJM proposal and that Southern Maryland proposal,” Gordon told me.
That might please restive stakeholders, or at least be something PJM’s board could go forward with knowing that the balance of its voting membership agreed with something similar.
“We maintain our view that a final proposal could resemble the proposed solution package from PJM staff,” the ClearView note said. “We also think the Board could propose reforms to PJM’s PRD program. Indeed, as noted above, SMECO’s revisions to the service gained majority support.”
The PJM plan also included relatively uncontroversial reforms to load forecasting to cut down on duplicated requests and better share information, and an “expedited interconnection track” on which new, large-scale generation could be fast-tracked if it were signed off on by a state government “to expedite consideration of permitting and siting.”
Gordon said that the market monitor’s complaint could be read as the organization “desperately trying to get FERC to weigh in” on its side, even if PJM is more likely to go with something like its own staff-authored submission.
“The key aspect of the market monitor’s proposal was that PJM should not allow a data center to interconnect until there was enough generation to supply them,” Gordon explained. During the meeting preceding the vote, “PJM said they didn’t think they had the authority to deny someone interconnection.”
This dispute over whether the electricity system has an obligation to serve all customers has been the existential question making the debate about how to serve data centers extra angsty.
But PJM looks to be trying to sidestep that big question and nibble around the edges of reform.
“Everybody is really conflicted here,” Gordon told me. “They’re all about protecting consumers. They don’t want to see any more increases, obviously, and they want to keep the lights on. Of course, they also want data center developers in their states. It’s really hard to have all three.”
Atomic Canyon is set to announce the deal with the International Atomic Energy Agency.
Two years ago, Trey Lauderdale asked not what nuclear power could do for artificial intelligence, but what artificial intelligence could do for nuclear power.
The value of atomic power stations to provide the constant, zero-carbon electricity many data centers demand was well understood. What large language models could do to make building and operating reactors easier was less obvious. His startup, Atomic Canyon, made a first attempt at answering that by creating a program that could make the mountains of paper documents at the Diablo Canyon nuclear plant, California’s only remaining station, searchable. But Lauderdale was thinking bigger.
In September, Atomic Canyon inked a deal with the Idaho National Laboratory to start devising industry standards to test the capacity of AI software for nuclear projects, in much the same way each update to ChatGPT or Perplexity is benchmarked by the program’s ability to complete bar exams or medical tests. Now, the company’s effort is going global.
On Wednesday, Atomic Canyon is set to announce a partnership with the United Nations International Atomic Energy Agency to begin cataloging the United Nations nuclear watchdog’s data and laying the groundwork for global standards of how AI software can be used in the industry.
“We’re going to start building proof of concepts and models together, and we’re going to build a framework of what the opportunities and use cases are for AI,” Lauderdale, Atomic Canyon’s chief executive, told me on a call from his hotel room in Vienna, Austria, where the IAEA is headquartered.
The memorandum of understanding between the company and the UN agency is at an early stage, so it’s as yet unclear what international standards or guidelines could look like.
In the U.S., Atomic Canyon began making inroads earlier this year with a project backed by the Institute of Nuclear Power Operators, the Nuclear Energy Institute, and the Electric Power Research Institute to create a virtual assistant for nuclear workers.
Atomic Canyon isn’t the only company applying AI to nuclear power. Last month, nuclear giant Westinghouse unveiled new software it’s designing with Google to calculate ways to bring down the cost of key components in reactors by millions of dollars. The Nuclear Company, a startup developer that’s aiming to build fleets of reactors based on existing designs, announced a deal with the software behemoth Palantir to craft the software equivalent of what the companies described as an “Iron Man suit,” able to swiftly pull up regulatory and blueprint details for the engineers tasked with building new atomic power stations.
Lauderdale doesn’t see that as competition.
“All of that, I view as complementary,” he said.
“There is so much wood to chop in the nuclear power space, the amount of work from an administrative perspective regarding every inch of the nuclear supply chain, from how we design reactors to how we license reactors, how we regulate to how we do environmental reviews, how we construct them to how we maintain,” he added. “Every aspect of the nuclear power life cycle is going to be transformed. There’s no way one company alone could come in and say, we have a magical approach. We’re going to need multiple players.”
That Atomic Canyon is making inroads at the IAEA has the potential to significantly broaden the company’s reach. Unlike other energy sources, nuclear power is uniquely subject to international oversight as part of global efforts to prevent civilian atomic energy from bleeding over into weapons production.
The IAEA’s bylaws award particular agenda-setting powers to whatever country has the largest fleet of nuclear reactors. In the nearly seven decades since the agency’s founding, that nation has been the U.S. As such, the 30 other countries with nuclear power have largely aligned their regulations and approaches to the ones standardized in Washington. When the U.S. artificially capped the enrichment levels of traditional reactor fuel at 5%, for example, the rest of the world followed.
That could soon change, however, as China’s breakneck deployment of new reactors looks poised to vault the country ahead of the U.S. sometime in the next decade. It wouldn’t just be a symbolic milestone. China’s emergence as the world’s preeminent nuclear-powered nation would likely come with Beijing’s increased influence over other countries’ atomic energy programs. As it is, China is preparing to start exporting its reactors overseas.
The role electricity demand from the data centers powering the AI boom has played in spurring calls for new reactors is undeniable. But if AI turns out to have as big an impact on nuclear operations as Lauderdale predicts, an American company helping to establish the global guidelines could help cement U.S. influence over a potentially major new factor in how the industry works for years, if not decades to come.
Current conditions: The Northeastern U.S. is bracing for 6 inches of snow, including potential showers in New York City today • A broad swath of the Mountain West, from Montana through Colorado down to New Mexico, is expecting up to six inches of snow • After routinely breaking temperature records for the past three years, Guyana shattered its December high with thermometers crossing 92 degrees Fahrenheit.
The Department of Energy gave a combined $800 million to two projects to build what could be the United States’ first commercial small modular reactors. The first $400 million went to the federally owned Tennessee Valley Authority to finance construction of the country’s first BWRX-300. The project, which Heatmap’s Matthew Zeitlin called the TVA’s “big swing at small nuclear,” is meant to follow on the debut deployment of GE-Hitachi Nuclear Energy’s 300-megawatt SMR at the Darlington nuclear plant in Ontario. The second $400 million grant backed Holtec International’s plan to expand the Palisades nuclear plant in Michigan where it’s currently working to restart with the company’s own 300-megawatt reactor. The funding came from a pot of money earmarked for third-generation reactors, the type that hew closely to the large light water reactors that make up nearly all the U.S. fleet of 94 commercial nuclear reactors. While their similarities with existing plants offer some benefits, the Trump administration has also heavily invested in incentives to spur construction of fourth-generation reactors that use coolants other than water. “Advanced light-water SMRs will give our nation the reliable, round-the-clock power we need to fuel the President’s manufacturing boom, support data centers and AI growth, and reinforce a stronger, more secure electric grid,” Secretary of Energy Chris Wright said in a statement. “These awards ensure we can deploy these reactors as soon as possible.”
You know who also wants to see more investment in SMRs? Arizona senator and rumored Democratic presidential hopeful Ruben Gallego, who released an energy plan Wednesday calling on the Energy Department to ease the “regulatory, scaling, and supply chain challenges” new reactors still face.
Since he first emerged on the political scene a decade ago, President Donald Trump has made the proverbial forgotten coal miner a central theme of his anti-establishment campaigns, vowing to correct for urbanite elites’ neglect by putting workers’ concerns at the forefront. Yet his administration is now considering overhauling black lung protections that miners lobbied federal agencies to enact and enforce. Secretary of Labor Lori Chavez-DeRemer will “reconsider and seek comments” on parts of the Biden-era silica rule that mining companies and trade groups are challenging in court, the agency told E&E News. It’s unclear how the Trump administration may seek to alter the regulation. But the rule, finalized last year, reduced exposure limits for miners to airborne silica crystals that lodge deep inside lung tissue to 50 micrograms from the previous 100 microgram limit. The rule also required companies to provide expanded medical tests to workers. Dozens of miners and medical advocates protested outside the agency’s headquarters in Washington in October to request that the rule, expected to prevent more than 1,000 deaths and 3,700 cases of black lung per year, be saved.
Rolling back some of the protections would be just the latest effort to gut Biden-era policy. On Wednesday, the White House invited automotive executives to attend what’s expected to be an announcement to shred fuel-efficiency standards for new vehicles, The New York Times reported late on Tuesday.

The average American spent a combined 11 hours without electricity last year as a result of extreme weather, worse outages than during any previous year going back a decade. That’s according to the latest analysis by the U.S. Energy Information Administration. Blackouts attributed to major events averaged nearly nine hours in 2025, compared to an average of roughly four hours per year in 2014 through 2023. Major hurricanes accounted for 80% of the hours without electricity in 2024.
The latest federal grants may be good news for third-generation SMRs, but one of the leading fourth-generation projects — the Bill Gates-owned TerraPower’s bid to build a molten salt-cooled reactor at a former coal plant in Wyoming — just cleared the final safety hurdle for its construction permit. Calling the approval a “momentous occasion for TerraPower,” CEO Chris Levesque said the “favorable safety evaluation from the U.S. Nuclear Regulatory Commission reflects years of rigorous evaluation, thoughtful collaboration with the NRC, and an unwavering commitment to both safety and innovation.”
TerraPower’s project in Kemmerer, Wyoming, is meant to demonstrate the company’s reactors, which are designed to store power when it’s needed — making them uniquely complementary to grids with large amounts of wind and solar — to avoid the possibility of a meltdown. Still, at a private lunch I attended in October, Gates warned that the U.S. is falling behind China on nuclear power. China is charging ahead on all energy fronts. On Tuesday, Bloomberg reported that the Chinese had started up a domestically-produced gas turbine for the first time as the country seeks to compete with the U.S. on even the fossil fuels American producers dominate.
It’s been a rough year for green hydrogen projects as the high cost of producing the zero-carbon fuel from renewable electricity and water makes finding customers difficult for projects. Blue hydrogen, the version of the fuel made with natural gas equipped with carbon capture equipment, isn’t doing much better. Last month, Exxon Mobil Corp. abandoned plans to build what would have been one of the world’s largest hydrogen production plants in Baytown, Texas. This week, BP withdrew from a blue hydrogen project in England. At issue are strict new standards in the European Union for how much carbon blue hydrogen plants would need to capture to qualify as clean.
You’re not the only one accidentally ingesting loads of microplastics. New research suggests crickets can’t tell the difference between tiny bits of plastics and natural food sources. Evidence shows that crickets can break down microplastics into smaller nanoplastics — which may be even worse in the environment since they’re more easily eaten or absorbed by other lifeforms.
