On Trump’s mineral paradox, China’s Great Green Wall, and sodium-ion batteries

Current conditions: After devastating the U.S. island of Rota in the Northern Mariana Islands territory, Super Typhoon Bavi is barreling toward Taiwan with winds of up to 200 miles per hour • Rare tornadoes brought on by storms touched down in China’s Hubei province, leaving 11 dead • Temperatures in Madrid are hovering at around 100 degrees Fahrenheit all week as the Spanish capital roasts in Europe’s latest heat wave.
Exactly three weeks after President Donald Trump signed a formal memorandum to halt the bombing campaign against Iran that the United States and Israel embarked on nearly five months ago, the war is back on. After Washington accused Tehran of launching missiles at tankers passing through the Strait of Hormuz this week, Trump officially declared the resumption of combat. Speaking Wednesday morning at the NATO summit in Turkey, Trump called the Iranian regime “scum,” “sick people,” and “vicious, violent people” when asked about the peace pact during a press conference. “If they had a nuclear weapon, they’d use it,” Trump said. “So as far as I’m concerned, it’s over.” He spent the rest of the day posting more than a dozen videos and photos on his Truth Social account purportedly showing U.S. missile strikes in Iran. “This is in retribution for yesterday’s bombing of ships by Iran,” Trump wrote in one post. “If it happens again, it will get much worse!”
The market is certainly preparing for worse. The price of Murban crude, the benchmark for oil flowing out of the United Arab Emirates, spiked nearly 7% on Wednesday. The European benchmark, Brent crude, jumped more than 5%. The American pricing yardstick, West Texas Intermediate crude, rose by just over 1%. Last month, my colleague Matthew Zeitlin cautioned that, despite a ceasefire, it would take a while for the Strait of Hormuz to return to normal — and “even longer” for energy markets. Emphasis on that last part.
The world’s capacity to generate nuclear energy has increased by 2.2 gigawatts already this year as new Chinese reactors have come online at a rapid clip. By 2035, global nuclear capacity is on track to surge by 44% to 535 gigawatts, up from 372 gigawatts last year. That’s according to the latest forecast from the consultancy BloombergNEF. China, the unrivaled global leader in domestic reactor construction, is largely responsible for the projected spike. Today, the People’s Republic is the world’s No. 2 user of atomic energy behind the U.S., which has long operated the largest fleet of plants on the planet. But China is on pace to surpass the U.S. by 2030 with 102 gigawatts of nuclear capacity.
Among the more promising signs for the democratic world: The U.S. is now working with Japan and South Korea to commercialize new small modular reactor technologies. On Tuesday, at the margins of the NATO summit, U.S. Secretary of State Marco Rubio signed onto a memorandum with the foreign ministers of Japan and South Korea. The document “outlines opportunities for our three countries, which have complementary advantages in the civil nuclear field, to encourage mutually beneficial cooperation among their respective nuclear industries,” the State Department said in a statement.
Right after the presidential inauguration in January 2025, Matthew wrote a sharp piece identifying what he called the “paradox of Trump’s critical minerals crusade.” At issue was the fact that the new Trump administration planned to (and ultimately did) kill off policies designed to spur demand for domestically mined and processed minerals such as lithium, cobalt, and rare earths — even as he slashed barriers to increasing the supply of those metals. U.S. production of minerals is picking up as the White House brokers a growing list of deals to give the government equity stakes in mining firms in exchange for federal support for increasing output. Sure enough, the demand just isn’t there in the U.S. On Tuesday, the Financial Times reported that companies backed by the administration, including rare earths miner MP Materials, uranium producer Energy Fuels, and the rare earths refiner Phoenix Tailings are instead selling their goods to buyers in Asia. Japanese customers were “clamoring” for rare earth metals from Phoenix Tailings, CEO Nick Myers said. The materials the firm produces are ending up “primarily in Korea and Japan.”
That isn’t stopping Trump from reviving his calls for Washington to seize Greenland and its resources from Denmark, a founding NATO ally. Speaking at the conference in the Turkish capital of Ankara, the American president repeated his claim that the U.S. invasion of the world’s largest island following Copenhagen’s collapse to Nazi blitzkrieg in April 1940 should have qualified as a permanent conquest. “We took Greenland and then, stupidly, we gave it back,” Trump told reporters. “We shouldn’t have given it back to them. We’re the ones who need it. We need it for protection of the world, not just the United States.”

Not to be an old man about it, but I remember the Iraq War distinctly — the debates over the role of Baghdad’s oil and the calls from Congress for increased U.S. production with an eye toward energy independence. Here’s some data that will make you want to dismiss your humble millennial correspondent with an “ok boomer.” On Wednesday, the U.S. Energy Information Administration issued a definitive new analysis showing that U.S. petroleum exports hit a record high in April after Iran closed the Strait of Hormuz, forcing overseas buyers to find new sources of fuel. Exports increased to 13.6 million barrels per day, 15% more than the previous record set in March.
On the other end of the American energy spectrum, the nation’s largest provider of home battery and solar equipment just launched a distributed compute pilot program for artificial intelligence servers. Under the program, Sunrun will coordinate “the selling of inference capacity to enterprise compute buyers.” In other words, homeowners can earn money by hosting “compute nodes” — small servers —that then supply output to AI companies in much the same way Sunrun’s customers are paid by giving the virtual power plant operators access to solar panels and batteries. “Over nearly two decades, we have perfected our ability to operationalize, finance, and scale distributed assets,” Paul Dickson, Sunrun’s president and chief revenue officer, said in a press release. “We are now using our leadership position in distributed home energy and proven infrastructure to bring compute closer to the sources of energy and inference.”
Much like the United Nations effort to plant trees at the southern edge of the Sahara to keep the desert at bay, China is building a Great Green Wall. Since 1978, the country has planted 66 billion trees and plans another 34 billion by 2050 in a bid to slow the spread of the Gobi and Taklamakan deserts. A new study using satellite measurements of leafy areas found that the planted forests are greening much faster than wild ones. Younger trees grow faster. But even at similar ages, planted stands grew 4.6% faster, meaning they can absorb more carbon. The findings, according to Fertilizer Daily, “suggest global climate models should better distinguish forest types and age when accounting for carbon.”
Sodium-ion technology, as Heatmap’s Katie Brigham explained two years ago, promises cheaper, less combustible batteries than its dominant lithium-ion cousin. But it remains niche and underdeveloped. Perhaps not for long. On Wednesday, sodium battery startup Peak Energy announced plans for a factory in Sacramento capable of producing 4 gigawatt-hours of sodium battery systems annually. “America needs energy storage that is lower cost, more affordable, more reliable and purpose-built to meet the demand coming onto the grid,” Peak Energy CEO Landon Mossburg said in a statement. “This facility is proof that America can lead not only in inventing the technology, but in building it at scale.”

Tales from a day of “thoughtful dialogues on energy, climate change, and human lives” on Day 3 of New York Climate Week.
“I’m here because I love thoughtful dialogues on energy, climate change, and human lives,” Energy Secretary Chris Wright told my colleague Robinson Meyer this afternoon. “That’s been a passion my whole life, and nothing will change that.”
It’s our passion too — and was a defining theme of Heatmap House on Wednesday at New York Climate Week, with 27 sessions across topics including clean energy development, U.S. climate policy, the future of mobility, climate tech, and reindustrialization. From Wright backpedaling on President Trump’s embrace of a diesel export ban to former Vice President Al Gore asserting that 2026 might mark “the positive tipping point on climate,” it was a full day of news, contrarian opinions, juicy predictions, and lots and lots of coffee (consumed by yours truly).
Early in the day, Carlos Araque, the CEO and co-founder of Quaise, an advanced geothermal company, started things off by addressing the elephant in the room: potentially imminent movement on permitting reform. “It’s always easy to be picky and want for more,” he acknowledged, although he added that “my ask has always been — as far back as 2018 — if you can do for geothermal what you do for oil as in terms of regulatory permitting exclusions, then you’re moving 90% of the way to the goal. So that’s happening — that’s slowly and surely happening.”

New Jersey Governor Mikie Sherrill also spoke about permitting reform at a local scale. “You cannot simply say to people, ‘Sorry, your bills are just going to keep skyrocketing,’” she stressed. “That is not the answer, which is why we’ve acted so aggressively. I approved 18 solar and battery storage projects in the first six months [of my term]. We knew the federal credits were going to run out if we did not get that done, so that’s why we had to take on permitting reform right away to make sure we were growing that.”
And while Jane Flegal, the principal at Flegal Energy Advisors, didn’t have any secret insight into the potential deal, she broke down her predictions into three buckets: reforms to conventional environmental statutes such as the National Environmental Policy Act, the Clean Water Act, and the National Historic Preservation Act; transmission, “which, no one knows what’s in there, but we all know what was in the Manchin deal, and I think we can and should expect something at least that ambitious;” and permitting certainty, which would constrain executive power to cancel permits after they’ve been issued.
Chris Hayes, the host of All In with Chris Hayes on MS NOW and a former climate reporter, took the stage just after Gore, who marked the 20-year anniversary of his Academy Award-winning documentary An Inconvenient Truth. Like Gore, Hayes was in a reflective mood. “I think to some degree, we’re kind of moving forward in this understanding that all of us are implicated in the system that’s going to change very slowly over time,” he said, calling it one of the lessons of the past 20 years. “But I think there was a high-water mark of consumer activism that is sort of gone.”
Then, of course, there was Wright. The energy secretary — whom climate insiders have described to us as the biggest climate villain in the Trump administration after Trump himself — talked to Rob about as many fuels as they could cover. Wind: “There have been very spirited dialogues in the administration about this. I do believe a successful permitting reform thing changes the playing field for anything you want to build in this country, including wind.” Nuclear: “Our thing is just to try to get it back on its feet and get out of the way.” Natural gas: “Gas in my lifetime is going to be the American energy superpower for sure, but you never want all your eggs in one basket.” Batteries: “I’m all in.” And EVs: “Should we have the broader America subsidizing, you know, the habits of wealthy people? I don’t think we should.”
Electric vehicles also came up in our mobility session, of course, along with other forms of mobility including ferries, subways, and rail. “It’s not something we talk about very much in the U.S.,” Laura Fox, the co-founder and managing partner of Streetlife Ventures, told me, adding that “we have a really great rail freight network that is underutilized and that typically saves shippers 30% to 40% when they’re shipping goods in the current environment.” (Representative Mike Levin of California also shared that if he could only connect two places in his proposed giant high-performance rail system, “I’d like to see the line between Los Angeles and San Diego solidified.”)
The evening wrapped with a focus on reindustrialization. Tom Steyer, the co-executive chair of Galvanize Solutions, told us he’s doing fine after his unsuccessful bid for California governor. (Nothing a trip to Tahoe with the family couldn’t cure.) He also shared that the climate movement may have lessons for the modern movement opposing AI and data centers. The world’s richest companies can’t just “come in and take people’s water, especially at a time when people are so water insecure,” he stressed. “How could that possibly be right?”
AI — and water — also came up in conversation with Emilio Tenuta, the senior vice president and chief sustainability officer of Ecolab, which provides industrial and commercial water and hygiene solutions. (Ecolab also sponsored our reindustrialization section.) He argued that “what we really need to focus on is the Water Efficiency Index” when evaluating, for example, semiconductor fabrication plants, because it contextualizes water use in more absolute terms than traditional metrics.
Page Crahan, general manager of Tapestry, an Alphabet X moonshot project that uses AI to develop a model of the grid’s electricity network, zeroed in on how best to use artificial intelligence. “We had 10 years to build what it took us 110 years to build globally” in order to meet anticipated energy demand, she told my colleague Jael Holzman. “And that was in 2023, before data centers.” For “computationally intensive challenges, data-heavy challenges, and certainly running simulations and insights for a system this size,” AI is a good use case, she said.
Tapestry is using its models in partnership with PJM Interconnection (as we’ve covered here at Heatmap) — and speaking of PJM, its executive director of strategic policy and external affairs, Asim Haque, spoke to my colleague Matthew Zeitlin next. “If you do not bring your own new capacity, we are going to curtail you before we curtail your average residential consumer for sure,” he said, adding, “this is a concept that is pending in front of the FERC right now. We can talk about carrots. We can talk about sticks. I don’t know which one this is. I think from the data center perspective, it’s likely a stick.”
Josh Parker, the head of sustainability at Nvidia, rounded the day out on a positive note. “The good news is, we are very quickly unlocking new capacity with clean energy,” he said, including developing new clean energy technologies like advanced fission and geothermal. “All of these technologies are benefiting from AI, and so that, coupled with the fact that data center operators with AI factories generally are some of the largest consumers of clean energy and are still are looking for all the clean energy they can, leads me to believe — and I think this is the most credible forecast — that very soon we’re going to see all of that convert over to clean as soon as we can get through the supply constraints that we’re currently in.”
If you were with us in person, thank you again. You’re what made our event one to remember. And if you weren’t able to join us this year — we hope to see you in 2027.
But wait! Before I send you on your way, you can find all of our coverage of the day below along with some additional quotes from some of my favorite conversations:
The Commonwealth Fusion Systems CEO made his case at Heatmap House.
Without billions in new federal investment the United States may lose its pole position in the global race to be the first nuclear fusion superpower, Commonwealth Fusion Systems CEO Bob Mumgaard told attendees at Heatmap House in New York City.
When asked onstage whether Commonwealth Fusion could still develop its fusion aspirations at scale without U.S. government financing, Mumgaard said: “I think so – it’s a question of the timing and the place.” Then he suggested that the company — and the industry — might go elsewhere if the country doesn’t put more capital into the growing sector. “There are offers on the table to build nuclear fission power plants not in the United States, so we can do that.”
You’d be forgiven if you thought Commonwealth and nuclear fusion was already doing well. The Massachusetts-based pioneer in fusion technologies raised $1 billion in new investment just a couple months ago. Generally speaking, innovation in nuclear power is incredibly popular in Congress, which has an influential bipartisan Fusion Energy Caucus. Commonwealth has received public support from the Trump administration’s Energy Department, as has one of the Heatmap House sponsors, Inertia.
But we’re talking about nuclear fusion, a still-futuristic form of energy generation seeking to harness the power of stars exploding in contained environments. It’s an insanely promising tech moonshot.
Mumgaard said the company is aiming for its tech to provide electrons onto the grid by the 2030s. He also said a Fusion Industry Association request to Congress and the Trump administration for $10 billion of investment might be what’s needed for that power to be American first.
“We debated that [amount] with the industry association, and you have to say what gets the job done. It’s a disservice to lowball what’s needed,” he told my colleague Katie Brigham. “This is a very important thing. It’s an entirely new industry. Let’s treat it as such.”
He added his view that U.S. fusion development is essentially an energy security maneuver, and that competition with China on fusion should be seen as parallel to the race for dominance in artificial intelligence.
“Think about what it means in a technological race. Power is the thing that powers the next economy, right?” Mumgaard said. “All the geostrategic strife we have right now is about power in the form of natural resources. Who has them? What are they? What boats are they on through what body of water? Fusion takes all of that off the table.”
Representative Mike Levin, It’s Electric, Rivian, and more showed up for the mobility session at Heatmap House.
On the surface, the climate case for electric vehicles is simple: Battery-powered cars can eliminate our need to burn dirty gasoline and diesel, and as more renewables come onto the grid, they’ll only run more and more cleanly. But the benefits that can be gained from electrifying the vehicle fleet run far deeper, a case that a variety of speakers made at Heatmap House on Wednesday as part of New York Climate Week.
Andrew Peterman, director of advanced energy solutions at the EV maker Rivian, explained how electric vehicles are becoming a multi-tiered grid solution. Rivian itself is cooperating with drivers and utilities to create automatic smart charging so that EVs can charge when energy is abundant and inexpensive, saving the user money — in some cases as much as $1,000 per year — and easing strain on the grid. Doing so helps to keep electricity prices down, which is good for the country and for the bottom line of an electric vehicle maker.
“Our ability to sell and give people value out of an electric vehicle can only be enabled if we transform the grid to be able to be affordable, reliable, and cleaner for everyone,” Peterman told Heatmap deputy editor Jillian Goodman. “We need to use our role in the energy system to enable customers to get more value out of the grid. So everything we do is about grid transformation to enable electric vehicles to have an even stronger and stronger value proposition. When we bring down electricity costs, that brings down the total cost of ownership for our vehicle owners.”
Of course, energy can go in the other direction, too. Now that millions of EVs are on the road, the multitude of kilowatt-hours stored in EV batteries can be a grid asset. That goes for vehicle-to-grid integration, where EVs can discharge energy to help balance the grid when they’re not driving. But it’s an especially compelling proposition when those batteries get older and are no longer optimal for powering vehicles. Rivian is working with partners such as Redwood Materials to recycle old EV batteries and to repurpose some as grid storage. The same is true at Waymo, whose fleet of autonomous, only-electric rideshare vehicles have racked up hundreds of thousands of miles in some cases.
“Our fleets are sometimes outlasting our batteries where they still work, but they’re just not optimal for the ride-hailing fleet,” Waymo head of environment and sustainability Adam Lenz told Nico Lauricella, Heatmap’s CEO and editor in chief. “So we’re taking those batteries out, refreshing them, and then there’s still a lot of life left on this battery. We’re working with a partner that’s based out of L.A. County where we provide service and they’re deploying those batteries to support front of the meter grid storage.” (Waymo is also a sponsor of Heatmap House.)
It’s clear that the rideshare economy will be dominated by electric vehicles, and Lenz argued that this fact helps extend the climate benefits of electrification and autonomy to people who don’t want to drive or have been priced out by the upfront costs of an EV. The promise that self-driving cars will ultimately be much safer compared to those driven by fallible humans makes it safer to walk or bike, the most sustainable transportation methods. Waymo recently introduced a partnership with Visa to give San Francisco Bay Area riders a $2.85 Waymo account credit (the price of a bus ride in S.F.) when they combine a rideshare trip with a train or bus linkup to create a mulit-modal journey — a roundabout way to create “free” buses.
Across the country, EV charging could help give New York City not only cleaner skies but also improved grid management. The city’s Green Ride Initiative is meant to have New York’s taxi and rideshare trips be majority-electric by 2030, yet NYC has been a charging desert compared to other dense cities like London. Tiya Gordon, co-founder and COO of charging company it’s electric, came to Heatmap House to discuss her company’s recent win of a contract to install 700 new street chargers in New York, which has only 88 today.
It’s not just how many chargers are going in, she said, but where — the majority will go into neighborhoods in Brooklyn and Queens where rideshare drivers live and park their cars overnight. Albert Gore, executive director of the Zero Emission Transportation Association, added: “It makes a lot of sense also when you think about the impact to the grid. If you are directing a lot of that charging at night, particularly for these high mileage use cases, that actually puts downward pressure on electricity rates. EVs are a very, very flexible load.”
