On Japan’s atomic ‘Iron Lady,’ Electra’s supercharge, and a mineral deal Down Under

Current conditions: Tropical Storm Melissa is barreling toward Haiti and Jamaica carrying a payload of as much as 16 inches of rain for certain parts of the Caribbean • A coldfront is set to drop temperatures by as much as 15 degrees Fahrenheit over the Great Lakes states • Temperatures in the French overseas territory of Juan de Nova hit nearly 94 degrees Tuesday, the hottest October day in the history of the French Southern Territories.
US Wind told a federal court that it will go bankrupt if President Donald Trump succeeds in revoking its building permits. The Baltimore-based developer testified on the fate of its 2.2-gigawatt Maryland Offshore Wind project in response to a lawsuit brought by the Department of the Interior and the City Council of Ocean City, Maryland. “If the plan is lost, surrendered, forfeited, revoked or otherwise not maintained in full force and effect, US Wind’s investors have the right to declare US Wind to be in default on the repayment of the company’s debt and/or refuse to extend the additional financing needed to complete construction of the project,” the company told the court, according to an update on the energy consultancy TGS’ 4C Offshore news website. “Either of these consequences could result in US Wind’s bankruptcy.”
The Trump administration’s “total war on wind,” as Heatmap’s Jael Holzman described the multi-agency onslaught against offshore projects, has drawn a backlash in recent months. As I reported last month in this newsletter, a federal judge temporarily stayed Trump’s stop-work order on a 80% complete wind farm off Rhode Island’s coast. Even the oil industry has come out to support the wind sector, as I wrote earlier this month, with Shell’s top U.S. executive warning that the precedent the administration had set would harm fossil fuel producers once Democrats return to power. Yet the effects of the administration’s policies are starting to pinch.
Electra announced a series of major deals on Tuesday as the green iron startup unveiled its debut demonstration facility in Boulder, Colorado. Just a month after Microsoft agreed to buy green steel for its data centers from Sweden’s green steelmaker Stegra, Facebook owner Meta agreed to buy environmental attribute credits linked to emissions cut from Electra’s clean iron. The startup also announced three major offtake agreements — the steelmaker Nucor, the European metal trader Edelstahl Group, and Japanese steel-trading giant Toyota Tsusho all signed deals for Electra’s iron. Meanwhile, Electra brought on new financing. Bill Gates’ Breakthrough Energy invested $50 million in grants into the company, while Colorado Governor Jared Polis provided the five-year-old startups with an $8 million tax credit from the state’s clean industrial financing program. And all that is just what the company announced Tuesday. Earlier this year, as Heatmap’s Katie Brigham reported, Electra closed a $186 million Series B round.

The top U.S. solar trade group, the Solar Energy Industries Association, is looking for a new leader. After eight years in office, Abigail Ross Hopper, the lobby organization’s chief executive, announced her departure Tuesday amid what she called a “challenging” year for the industry in her public exit letter. When she took office in 2017, the solar industry had a total capacity of 36 gigawatts and just over 1 million residential customers. By today, the industry has grown to more than 255 gigawatts and more than 5.5 million residential customers. Despite struggles competing against China, U.S. solar manufacturing capacity vaulted from 14th globally to the world’s third-largest hub of photovoltaic factories. “The growth we’ve experienced over the years is a result of our collective grit and determination,” she wrote in the letter. “We’ve navigated fierce policy battles and market challenges, from trade cases to tax debates, and yet we’ve always emerged stronger. We fought — and won — historic policy battles, at every level of government.” While the Trump administration’s cuts to solar programs have dulled growth forecasts, she said she was “optimistic” about the future. Her last day will be January 30, 2026.

After months of negotiations, the U.S. and Australia signed onto a two-way trade deal on critical minerals worth $8.5 billion. The move comes as China ratchets up export controls on rare earths and other metals over which Beijing dominates global supplies. Australia and Canada, whose economies heavily depend on mining, are widely considered the most dependable sources of minerals for the U.S., a dynamic highlighted last week by the cancellation of an American metal project by the leaders of a coup in Madagascar, as I reported for Heatmap. For Australia, the agreement “is a really significant deal,” Hayley Channer, the director of the economic security program at the United States Studies Centre at the University of Sydney, told The Guardian. “I’m surprised how good it is. The fact that any U.S. money is coming to Australian companies is huge; we really need this money. I don’t think it could have gone any better.”
Japan just elected its first female prime minister, the arch-conservative former minister of economic security Sanae Takaichi. Like Margaret Thatcher, the first woman to serve as British prime minister, Takaichi has been dubbed the Iron Lady due to her hard-line nationalistic views. But uranium may be a better metal for the nickname. Like Thatcher, Takaichi has vowed to restore Japan’s nuclear industry to its former might. Less than half of Japan’s 33 operable nuclear reactors are currently online and generating electricity, a legacy of the mass shutdown that followed the 2011 Fukushima-Daiichi plant. In lieu of atomic energy, Japan — which lacks the land for vast wind and solar installations — has turned instead to costly liquified natural gas imports. To Takaichi, who wants to remilitarize Japan and take a more aggressive stance toward China, this creates a vulnerability. Without domestic gas fields, Japan relies on imports whose routes the Chinese navy could disrupt in a conflict, weaponizing blackouts in much the same way Russia has in Ukraine. Japan’s offshore wind efforts are badly delayed. And Takaichi has warned that Beijing’s grip over global manufacturing of photovoltaic panels makes solar a threat, as well.
Japan isn’t the only country looking to revive its past atomic ambitions. South Africa’s government approved the state-owned utility Eskom’s integrated resource plan last week, which included starting work again on the company’s abandoned pebble-bed modular reactor program. First proposed in 1999, the technology is billed as safer than light water reactors and more versatile, with the potential for use in more heavy industry settings. But South Africa canceled the program in 2010 after spending $980 million developing the reactor. The country currently depends on coal for nearly 60% of its electricity.
Scientists discovered an ancient climate archive in a remote cave in northern Greenland. In a study published in Nature Geoscience, the researchers found calcite deposits that only form when the ground is unfrozen and water flows. The findings cast new light on past warm periods in the Earth’s climate, particularly the Late Miocene, which began about 11 million years ago. “These deposits are like tiny time capsules,” Gina Moseley, a geologist with the University of Innsbruck in Austria and an author of the study, said in a press release. “They show that northern Greenland was once free of permafrost and much wetter than it is today.”

On offshore mining, New Jersey’s offshore wind, and China’s oil breakthrough
Current conditions: Severe thunderstorms are pummeling the Mississippi Valley, particularly in Arkansas • Heavy rain has deluged much of the Somali capital of Mogadishu • Temperatures in the northern Indian state of Uttar Pradesh are reaching 110 degrees Fahrenheit.

Let’s, for a moment, recast The Simpsons’ role in nuclear energy discourse. Rather than fearmongering with a pseudoscientific depiction of fission energy, imagine if that sign in the scene from the opening credits that reads “days without an accident” instead tracked how long it’s been since the United States started work on building newer, sleeker, and more efficient reactors. Until last week, the sign would have clocked 4,539 days — 13 years since construction began on the AP1000 reactor known as Plant Vogtle’s Unit 4. But last Friday, the next-generation reactor startup Kairos Power broke ground on its demonstration plant in Tennessee. Then this week, the Bill Gates-founded reactor company TerraPower started construction on its debut power plant in Wyoming. “This isn’t a test reactor,” Chris Levesque, president and chief executive of TerraPower, told The Wall Street Journal. “This is a grid-scale nuclear reactor that will be built in 42 months.” While there’s plenty of ambition to build more reactors in the U.S., the country has a very, very long way to go to even catch up with China’s actual construction output.
California won’t be the site of any new plants anytime soon, at least until the state lifts its legislative ban on building new reactors. But keeping the state’s last operating nuclear station, Diablo Canyon, running from 2030 to 2045 could offer net savings of capital and operating costs totaling more than $7.6 billion, or more than $500 million per year of continued operations, according to a new analysis by the Massachusetts Institute of Technology’s Center for Energy and Environmental Policy Research. The savings “more than double when calculated relative to the current portfolio of alternatives mandated” in a state bill that lays out the renewable energy options for meeting Sacramento’s 2045 climate goals. “In that case,” the report states, “the total present value of savings for extending the life of” the plant “exceeds $20 billion, or more than $1.3 billion per year.”
If the Trump administration achieves its goal of siring a nuclear renaissance, we’re going to need a lot more reactor fuel than we currently have available. Much of that supply has come in recent years from Russia, but a U.S. law will fully ban imports in 2028. Both the Biden and Trump administrations have lavished funding on fuel enrichers. But on Thursday, the Department of Energy tapped a new tool: the Defense Production Act, the once-obscure Korean War-era statute that gives the federal government more powers to direct manufacturing. Under a newly launched Nuclear Fuel Cycle Consortium, the agency assembled representatives of more than 90 companies in the nuclear industrial base to “address all facets of the nuclear fuel supply chain including milling, conversion, enrichment, deconversion, fabrication, recycling, and reprocessing.” The Energy Department also kicked off a campaign it’s calling “Nuclear Dominance — 3 by 33.” The program aims by 2033 to “catalyze a secure and cost competitive domestic fuel supply chain,” speed up deployment of advanced reactors and reprocessing facilities, and find ways to use the DPA to speed up the buildout.

The Department of the Interior is creating a new office called the Marine Minerals Administration to manage oil drilling and seabed mining in America’s territorial waters. The new office, formed by reunifying two offices that had been split up after the 2010 Deepwater Horizon oil spill, threatens to weaken the environmental oversight of both the traditional oil and gas industry and the emerging mining sector. The move is “worrisome because it has the potential of bringing things back where they were, where there was this inherent conflict of interest between promotion of offshore oil and gas, and oversight safety,” Donald Boesch, emeritus professor at the University of Maryland Center for Environmental Science, told The New York Times. On Wednesday, Secretary of the Interior Doug Burgum said “these unification efforts will streamline bureaucracy.”

The New Jersey Board of Public Utilities has canceled the agreement it reached with PJM Interconnection in 2021 to develop wires and substations needed to send electricity from offshore wind turbines across the state. The board terminated the deal, Heatmap’s Jael Holzman wrote, “because much of New Jersey’s expected offshore wind capacity has either been canceled by developers or indefinitely stalled by President Donald Trump.” Despite soaring electricity prices, “New Jersey is now facing a situation in which there will be no identified, large-scale in-state generation projects under active development that can make use of [the agreement] on the timeline the state and PJM initially envisioned,” the board wrote in a letter to PJM requesting termination of the agreement. Newly-inaugurated Governor Mikie Sherrill has vowed to build new nuclear capacity in the state. As I wrote earlier this month, New Jersey became the latest state to lift its ban on new atomic energy plants.
Heatmap House kicked off San Francisco Climate Week with a day of conversations and roundtables with leading policymakers, executives, and investors. Two talks in particular are worth highlighting.
China is going all in on hydrogen as Beijing seeks ways to free itself from imported fossil fuels. Now the Dalian Institute of Chemical Physics has announced a facility in Xinjiang to use 1.5 gigawatts of wind power to produce green hydrogen mixed with an engineered material in a slurry bed reactor to transform solid asphalt into synthetic crude oil. If successful, the new process would allow China to import heavy oil and asphalt very cheaply from Central Asia and convert it into crude oil, the technology blogger TP Huang wrote on X, adding: “China is continuing work to turn crap into useful energy source by applying green electricity derivatives in its bid for energy independence.”
Co-founder Mateo Jaramillo described how the startup’s iron-air battery could help address the data center boom — and the energy transition
Well before the introduction of ChatGPT and Claude, Ireland underwent a data center construction boom similar to the one the U.S. is experiencing today.
That makes it a fitting location for Form Energy’s first project outside the U.S. Mateo Jaramillo, the CEO of the long-duration energy storage startup, described Ireland as “a postcard from the future” at Heatmap House, a day of conversations and roundtables with leading policymakers, executives, and investors at San Francisco Climate Week.
In a one-on-one interview with Robinson Meyer, Jaramillo went on to explain the potential of a 100-hour battery, calling it the duration at which you can “functionally replace thermal resources on the grid or compete with them.” Such storage capacity would not only bolster data centers’ power reliability but also speed up the transition from oil and gas to renewables.
Form Energy, which Jaramillo co-founded in 2017, is best known for its iron-air battery that can continuously discharge energy for 100 hours. In February, the startup announced a partnership with Google and the utility Xcel Energy to build the highest-capacity battery in the world, capable of storing 30 gigawatt-hours of energy, as Heatmap’s Katie Brigham reported.
Despite the troublesome state of renewables deployment in the U.S., energy storage firms like Form appear to be doing well, thanks to record load growth. “When we founded the company, we didn’t anticipate the boom of data center demand that we’re currently experiencing,” said Jaramillo. “But we did bet on the overall mega-trend being pretty firmly in place, which is electricity growth.”
In addition to load growth, battery manufacturers are still benefiting from the Inflation Reduction Act’s energy storage tax credits, which survived the deep cuts Republicans made to the signature climate law last summer. Jaramillo noted that customers can still claim a tax credit for purchasing energy systems, while a manufacturing protection credit also remains in place. “We absolutely qualify for both those things,” Jaramillo said. “In fact, 100 hours as a duration is written into the legislative text for the manufacturing [tax credit].”
Though batteries can help accelerate the retirement of natural gas plants by providing firm energy to supplement renewables’ generation, politicians’ fear of load growth seems to have forged a bipartisan consensus supporting batteries. For its part, Form Energy is focused on continuing to drive down the cost of its iron-air battery.
From “where we sit today,” Form Energy is “quite confident that we will hit that roughly $20 a kilowatt-hour cost within a very short period of time,” Jaramillo said.
At San Francisco Climate Week, John Reynolds discussed how the state is juggling wildfire prevention, climate goals, and more.
Blessed with ample sun and wind for renewables but bedeviled by high electricity prices and natural disasters, California encapsulates the promise and peril of the United States’ energy transition.
So it was fitting that Heatmap House, a day of conversations and roundtables with leading policymakers, executives, and investors at San Francisco Climate Week, kicked off with John Reynolds, president of the California Public Utilities Commission.
The CPUC oversees the most-populous state’s utilities and has the power to approve or veto electricity and natural gas rate increases. At Heatmap House, Reynolds — “one of California’'s most important climate policymakers,” as Heatmap’s Robinson Meyer called him — affirmed that affordability has been top of mind as power bills have risen to become a mainstream political issue across the country. California’s electricity prices are the second-highest in the nation, behind only Hawaii, according to the Electricity Price Hub.
“I’d really like to see us drive down the portion of household income that is consumed by energy prices,” Reynolds said in a one-on-one interview with Rob. “That’s a really important metric for making sure that we’re doing our job to deliver a system that’s efficient at meeting customer needs and is able to support the growth of our economy.”
The Golden State’s power premium has been exacerbated by the fallout from multiple wildfires that have devastated various parts of the state in recent years, which have necessitated costly grid upgrades such as undergrounding power lines. California-based utility PG&E has also invested in more futuristic fire solutions such as “vegetation management robots, power pole sensors, advanced fire detection cameras, and autonomous drones, with much of this enhanced by an artificial intelligence-powered analytics platforms,” as Heatmap’s Katie Brigham wrote shortly after last year’s fires in Los Angeles.
Affordability affects not just Californians’ financial wellbeing, but also the state’s ability to decarbonize quickly. “The affordability challenge that we’re seeing in electric and gas service is one that is going to make it more difficult to meet our climate goals as a state,” Reynolds said.
One contentious — and somewhat byzantine — aspect of California’s energy transition is how much of a financial incentive the CPUC should offer for residents to install rooftop solar. Net metering is a billing system that rewards households with solar panels for sending excess generation back to the grid. Three years ago, the CPUC adopted a new standard that substantially lowered the rate at which solar panel users were compensated.
“We had to slow the bleeding,” Reynolds said, referring to the greater financial burden paid by utility customers without solar panels. “The net billing tariff did slow the bleeding, but it didn’t stop it.”
Asked whether he is focused more on electricity rates (the amount a customer pays per kilowatt-hour) or bills (the amount a utility charges a ratepayer), Reynolds said both are important.
“If we can drive down electric rates, we’re going to enable more electrification of transportation and of buildings,” Reynolds said. “It’s really important to look at bills, because that is fundamentally what hits households. People’s wallets are limited by their bills, not by their rates.”
