On China’s Paris pact with Europe, Trump’s mineral geopolitics, and Google’s CO2 battery bet

Current conditions: The record-setting heat roasting more than 100 million Americans in the central U.S. is now headed for the densely populated Northeast • The American Samoan capital of Pago Pago faces “imminent” flash flooding on Friday amid days of rain • China just set a record for the highest number of hot days since March in its history.

Three years after the Palisades nuclear plant in Michigan became the country’s last atomic power station to permanently close, the facility is set to become the first in U.S. history to reopen after a final shutdown. On Thursday afternoon, the Nuclear Regulatory Commission issued its formal approval for the plant’s operating license, putting the single-reactor station on track to restart later this year, the plant’s owner, Holtec International, told me. With just 11 days to go before its license expired, Palisades’ previous owner opted to close down May 2022 rather than make necessary upgrades to continue operations. The Biden-era Loan Programs Office at the Department of Energy put up more than $1.5 to fund the effort. Despite freezing funding for other projects, the Trump administration shelled out the money to Holtec.
The project still faces obstacles. Holtec still needs to finalize repairs at the plant, which are subject to another NRC review. Anti-nuclear activists, meanwhile, vowed to appeal the NRC license. Still, Holtec’s President Kelly Trice said the NRC approval “represents an unprecedented milestone in U.S. nuclear energy.”
As the U.S. seeks to dismantle its climate regulations, China and the European Union signed a pledge Thursday to work together on cutting emissions. The document, dubbed “the way forward” following the 10-year anniversary of the Paris climate accords, called the 2015 pact brokered in the French capital “the cornerstone of international climate cooperation” that “all parties” should implement “in a comprehensive, good-faith and effective manner.” The two global powers also reached a deal for the emergency export of rare earth metals from China, which dominates their global trade, to European factories facing shortages of the materials, according to The New York Times.
The diplomatic communique comes as the U.S. goes through the process to quit the Paris Agreement for the second time. In 2017, Trump waited weeks to initiate the exit, and the protocol completed around the time of the 2020 election. That allowed then-President-elect Joe Biden to signal his plans to rejoin immediately, rendering the American withdrawal a brief hiccup. This time, however, the rules allow the U.S. to leave in about a year, and Trump started the process on his first day in office.

Just over a week after the Pentagon made a landmark investment in the United States’ only rare earths mine, President Donald Trump elevated his minerals adviser to the Nation Security Council. While the Trump administration did not confirm what Copley’s new position would entail, an industry source told E&E News the job change was a promotion for the military veteran and former mining executive, who would now serve as “both the White House mineral and supply chain czar.”
The move comes as China has sought to leverage its grip over global supplies of minerals such as rare earth metals and graphite by tightening export restrictions. While Trump’s military investment into California rare earth producer MP Materials may mirror China’s strategy of government funding for critical materials, Beijing has another thing going for it: Strong demand from electric vehicles. Therein lies what Heatmap’s Matthew Zeitlin recently called the “paradox” of Trump’s mineral policy: He’s making it easier to mine but eliminating the demand pull of electric vehicles and wind turbines.
Google has invested in small modular reactors, nuclear fusion, and even old-fashioned hydropower to shore up a steady supply of electricity for its reactors. This morning, the tech giant announced a strategic investment into carbon dioxide batteries, as I reported earlier today over at Latitude Media. The startup Energy Dome houses its technology in white, inflatable shelters similar to what you see over the courts at professional tennis tournaments. But inside is equipment that compresses and liquefies CO2, stores it in carbon steel tanks, then turns the liquid back into pressurized gas when energy is needed. Once reheated, the carbon dioxide is pumped through turbines to generate electricity for up to 24 hours at a time.
Headquartered in Milan, Energy Dome already had a deal for pilot plants in Wisconsin, Sardinia, and India, about eight hours west of Hyderabad. But Google said it plans to deploy the technology across the U.S., Europe, and Asia.
Maine is speeding up approvals for nearly 1,600 gigawatt-hours of renewable energy to make sure projects can tap into federal tax credits before the Trump administration cracks down, Canary Media's Sarah Shemkus reported. State regulators gave developers a July 25 deadline to take part in the fast-tracking program. The state is seeking enough bids to meet about 13% of its annual electricity demand. The program will give preference to projects sited on property where water or soil is contaminated by toxic PFAS, the cancer-causing substances known as “forever chemicals.”
Not all states are as welcoming of renewables. In Ohio, as Heatmap’s Jael Holzman reported yesterday, 26 out of 88 counties have “established restricted areas where wind or solar are prohibited.” The key to getting around local opposition is early community outreach and building a base of support for a project.
Consider the lobster, but listen to the shrimp. A new study in the journal Royal Society Open Science found that listening to the high-frequency sounds snapping shrimp produce “can be used as a real indicator of coral resilience,” Xavier Raick, postdoctoral fellow in bioacoustics at the Cornell Lab of Ornithology, said in a press release. “Snapping shrimp’s abundance is a mirror of coral cover. So if you have more corals, especially very big colonies, you have more snapping shrimps, and then you can use their sound as a proxy for the reef, structure, and health.”

The spinoff of Lawrence Livermore National Lab has a new 10-point plan to get onto the grid by the 2030s.
One of fusion energy’s newest startups, Inertia Enterprises, is betting that the fastest route to commercial fusion runs through one of the field’s oldest ideas. The company, which raised a $450 million Series A earlier this year, plans to build a power plant based on the laser-driven fusion system pioneered at Lawrence Livermore National Laboratory’s — the only tech yet to have produced more energy from a fusion reaction than it took to initiate it. Now, Inertia has shared its commercialization roadmap exclusively with Heatmap, detailing the 10 near-term capabilities it must demonstrate before this landmark experiment can become a grid-scale power plant by the mid-2030s.
The roadmap offers a route from the national lab’s impressive but commercially impractical fusion demonstrations to an economical power plant capable of producing electricity for the grid. At its core are a set of milestones — mostly aimed at developing cheap, mass-manufacturable components — that Inertia says it must clear before those individual systems can be integrated into a working plant. This road is not necessarily linear, however, as various teams will likely be working on many of these goals simultaneously.
At least the physics of Inertia’s approach are already proven, the startup’s CEO Jeff Lawson told me, pointing to the fusion experiments at Lawrence Livermore’s National Ignition Facility as a proof-of-concept. The lab’s demonstration of net energy gain caps more than six decades and $30 billion (in 2026 dollars) of U.S. fusion research. The remaining challenges, he argued, are all engineering-related, requiring “elbow grease, hard work, and smart people” rather than breakthroughs in fusion science.
"It seems to us like a startup or a commercial company of any variety should be focused on commercializing a proven scientific result, as opposed to actually trying to demonstrate the basic science to begin with," Lawson told me. Basic science, he argues, is better left to national labs and universities, where researchers can pursue "unbounded problems" that don’t align with the expectations and timelines of venture-backed startups.
Indeed, no fusion startup has yet achieved scientific breakeven, the milestone Lawrence Livermore first hit in 2022, and has since repeated numerous times. But leading players such as Commonwealth Fusion Systems and Helion Energy maintain that it’s only a matter of time before they validate the physics behind their own reactor designs, which they claim will be highly cost-competitive.
Lawson, on the other hand, readily acknowledged that Lawrence Livermore’s tech is uneconomical in its current form. His bet is simply that the more predictable path to a commercial reactor is to drive down the cost of the lab’s validated fusion approach, known as inertial confinement. This system relies on high-powered lasers firing at a millimeter-scale pellet of fusion fuel, compressing it to extreme temperatures and pressures until the atoms fuse. Today, the National Ignition Facility makes each individual fusion target by hand, a workable solution given that it only uses about a dozen per year.
That production model, however, isn’t remotely plausible for a grid-scale power plant. Because each fusion reaction lasts just a fraction of a billionth of a second, a commercial facility must fire its lasers at a fresh target about 10 times per second to generate continuous electricity — requiring the production of hundreds of millions of targets each year.
Scaling production to roughly a million pellets per day and making them inexpensive enough for commercial operation without compromising the strength or precision required for fusion ignition is central to Inertia’s roadmap. That includes goals five, seven, eight and nine — industrializing the manufacturing of the carbon shells that hold the fusion fuel, making the thin films that hold those carbon shells both durable and cheap, scaling up and automating fusion target assembly, and speeding up how fast targets are filled with the requisite deuterium-tritium fuel.
The other central focus of the roadmap is the laser system, which will ultimately consist of 1,000 individual units operating in concert to compress and heat the fusion fuel. Key priorities include reducing the system’s cost (goal two), dramatically increasing its firing cadence (goal three), and bolstering its durability to withstand high-intensity operations (goal four). Goal six also complements these efforts, calling for the development of a control system capable of tracking moving fusion targets to precisely align each laser shot.
Goals one and 10 bookend the journey with some broader milestones. The first focuses on increasing the fusion target’s energy gain — the ratio of fusion energy produced to laser energy delivered — to more than 25 times ignition. Today, the National Ignition Facility’s best-performing laser shot has yielded a gain of just over four times what it took to start the reaction. Goal 10 then zooms out to the ultimate objective: integrating all these technologies into a commercially viable power plant that can deliver either electricity or industrial heat to end customers.
To reach that point, Inertia has embarked on an industrial engineering hiring spree, recruiting folks with experience taking complex hardware systems from prototype to mass production, “not unlike the processes that are used in the semiconductor or consumer electronics world,” Lawson explained. The company has been making progress on its component development goals since the beginning of the year, he told me, and expects to announce the successful demonstration of a few of these milestones in the coming months. Lawson ultimately expects Inertia to complete the core components of its laser and target manufacturing systems by the middle of next year.
The team will spend the next two to three years integrating these individual pieces into two fully operational subsystems, a prototype laser system and a target manufacturing line. Around 2030, the company will begin combining those subsystems into a first-of-a-kind fusion power plant, which will also serve as the proving ground for the target chamber, tritium fuel breeding system, and power conversion system that turns fusion heat into electricity. By the middle of the next decade, Inertia aims to be generating power from this first plant, setting the stage for the company to build and connect additional grid-scale commercial power plants.
There are plenty of engineering trade-offs that the company will have to solve for. Take the decision around how to size the target chamber, for example. “If you make it bigger, your walls have an easier time and survive longer, but it’s more expensive. If you make it smaller, your walls have a tougher time because they’re closer to all the heat and energy that the fusion reaction is creating, but now your power plant costs less to build.”
But to Lawson, this represents exactly the type of problem Inertia was built to solve: complex engineering issues that come to the fore once scientists have demonstrated the fundamental physics are sound. He thinks other fusion companies may someday reach this stage, as well — though he’s unwilling to hazard a guess on exactly what approach or startup is best positioned to do so.
“There have been generations of scientists who’ve made their predictions about fusion energy and gotten it wrong,” he told me. “I’m not going to pretend to be smarter than them. All I’m here to say is, just knowing that one did work, we can commercialize it.”
