On nuclear waste, a Nevada solar farm, and lithium-harvesting nanorobots

Current conditions: France just ordered 4,000 more people to evacuate the wildfires that have now displaced a third of a million people across southwestern Europe • The heat dome in the southwestern United States is driving temperatures in Phoenix up to 113 degrees Fahrenheit by the end of the week • Temperatures in Tuscany are topping 100 degrees this week as Europe’s latest heat wave takes hold.
Just yesterday, I told you that China’s dominance over the manufacturing of the inverters needed to patch solar panels and batteries onto the grid and into data centers had peaked two years ago as Europe’s factories began booming. Hours after the newsletter landed in your inbox, the Trump administration unveiled plans to ban imports of Chinese power inverters in a bid to protect the U.S. buildout of artificial intelligence from sabotage and competition. On Tuesday, the Federal Communications Commission told CNBC its new restrictions aimed to safeguard the AI supply chain “from Chinese threats of disruption, data threat, and cyber attacks.” The measures also bar imports of Chinese-made humanoid and quadruped robots. As you may recall, Reuters broke news in May 2025 that the U.S. government had discovered rogue communications devices in the Chinese-made inverters. The story came out just a month after a frequency problem that stemmed from Spain’s struggle to sufficiently patch all of its solar generation on the grid triggered a blackout across Iberia, highlighting the sort of scenario a compromised “killswitch” device could set off in a bid to attack energy systems.
The ban is good news for America’s beleaguered solar manufacturing industry, which the Trump administration has championed with tariffs but hobbled by axing key federal tax credits that included bonuses for projects using domestically produced panels. T1 Energy, shares of which nosedived this week after the latest quarterly earnings showed losses far outpacing revenue, just spent another $135 million on patents from a rival in Singapore in a bid to vertically integrate production of a more efficient type of photovoltaic technology. Tesla, meanwhile, is promising to “multiply” American solar production by “an order of magnitude.” Yet Elon Musk’s behemoth is cutting long-term deals to buy other people’s solar power. The company just inked an agreement with a KKR-backed solar and battery project in Arizona to buy 90% of its output.

Reasonable people debate just how much electricity is needed to satisfy the demands of the data center boom — and the bears are likely to get a boost amid this week’s selloff of AI stocks. But the latest projections from the Rhodium Group forecast U.S. electricity demand growth to accelerate over the next 15 years, “growing faster than it has since the turn of the century.” Data centers will account for between 62% and 77% of the growth in 2030, and between 59% and 66% in 2040, ultimately reaching 17% of total electricity demand that year. Electric vehicles will make up the second-largest source of new demand growth in the low- and mid-emissions scenarios the consultancy outlined through 2040. In the high-emissions scenario, heavy industry will account for a quarter of the demand growth between 2025 and 2040. Overall, the findings show divergent pathways in the 2030s. By 2040, the U.S. will either reduce its greenhouse gas emissions by 41% below 2005 levels — or just 27%. Across all three scenarios, the “historic influx of renewables” coming online between now and 2030 keeps emissions declining. After 2030, however, the grid’s trajectory either continues to deploy nearly 53 gigawatts of renewables per year through 2040 in a low-emissions scenario or drops to 3 gigawatts per year in a high-emissions scenario where cheap natural gas dominates.
For months now, the Greenhouse Gas Protocol, the nonprofit behind a voluntary but widely used corporate standard for carbon accounting rules, has been revising its approach. Last year, my colleague Emily Pontecorvo explained the stakes of the revision process as an “obscure philosophical battle that could reshape the clean energy economy. In April, she broke news from whistleblowers that the changes underway were drumming up controversy. This morning she’s out with a new story on Greenhouse Gas Protocol’s plans to marry its standard to those by the International Organization for Standardization. The short of it is this: the changes are getting a lot of pushback, and credibility of the forthcoming new standard remains an open question.

For decades, the U.S. plan to deal with nuclear waste has focused on building a highly controversial repository in the Nevada desert. But that effort, as I explained yesterday, was put on indefinite hiatus in 2010 when the Obama administration canceled funding on behalf of then-Senate Majority Leader Harry Reid, a Nevada Democrat. In the meantime, states such as Texas and New Mexico have demonstrated that both Republican and Democratic governments are still willing to fight efforts to build intermediate-term storage facilities for nuclear waste in their states. On Tuesday, five states officially stepped up and made bids to host what the Department of Energy is calling its Nuclear Lifecycle Innovation Campuses, which will house startups that recycle spent nuclear waste into fresh fuel and medical isotopes. The Energy Department named Utah, Tennessee, Oklahoma, Louisiana, and Idaho as finalists for the facilities. “I’m pleased to announce that after reviewing 28 applications from 26 states, the Energy Department has selected five initial contenders to further explore building Nuclear Lifecycle Innovation Campuses,” Secretary of Energy Chris Wright said in a statement. “These campuses will be massive generators of economic growth, create thousands of high-paying jobs, and be crucial to unleashing America’s nuclear renaissance.”
Just last week, the Energy Department opened the door to nuclear projects sited on floating offshore platforms. It’s a novel idea for the U.S., but Russia launched its Akademik Lomonosov, a floating nuclear station, in 2019 in what is widely recognized as the world’s first real small modular reactor and only operating non-land nuclear plant. A new peer-reviewed study the World Nuclear Association conducted on the Rosatom-owned plant ranked it “on par with Russia’s top units,” World Nuclear News reported.
Trump’s permitting freeze for renewables projects started to thaw for solar in particular earlier this year as the administration faced mounting pressure to stop thwarting the fastest-growing source of power in a country increasingly starved for new and swiftly available sources of electricity. The easing, as my colleague Jael Holzman wrote, was also part of a legal strategy. Regardless of the reasoning, the thaw is continuing — and not just because of the literal heat dome pushing temperatures in the Southwest into the triple digits. On Tuesday, the Department of the Interior’s Bureau of Land Management announced plans to advance a solar project in the Nevada desert. The Mosey solar farm, which would produce enough power at maximum output for 200,000 homes, is now under evaluation at the agency’s Nevada office, the agency notified the Federal Register. The regulator plans to conduct an environmental analysis and a resource management plan tweak needed for a project in a utility corridor. E&E News credited the administration’s shift on this particular project to lobbying by the state’s Republican governor, Joe Lombardo.
The project is part of developer Clearway’s larger efforts in Nevada. Separately, the company has volunteered to scrap one of its other solar projects in favor of building a gas plant, Jael reported this week.
Yesterday, I told you the board of PJM Interconnection had scheduled an emergency auction to drum up 7 gigawatts of additional capacity to supply the electricity demand from data centers starting in 2028. It’s just one incremental way the nation’s largest grid system is “lurching toward reforms,” as my colleague Matthew Zeitlin wrote. It’s also inching toward more actual power infrastructure. On Wednesday, the developer Eolian Energy started construction on Flint Grid, a 1 gigawatt-hour storage project outside Columbus, Ohio. Located near a hub of data center and industrial power users, the Flint Grid project is “the first large-scale battery energy storage system to qualify for the PJM capacity market.” If it comes online in spring 2027 as promised on the project’s new website, it will represent more than half the new battery storage capacity in PJM’s line up for 2027 to 2028. The project is also the first grid-scale battery project permitted by the Ohio Power Siting Board and the largest in the PJM territory to date.
“There’s growing consternation about how the US can rapidly scale infrastructure to support America’s growing electricity demand, but not nearly enough conversation about how to use existing technology to unlock the wasted capacity that already exists on the grid,” Eolian founder and CEO Aaron Zubaty said in a statement. “This project requires hundreds of millions of dollars to construct, and we committed the necessary capital and resources years before today’s demand forecasts became headline news. As policymakers consider changes to competitive electricity markets, it’s critical that they avoid undermining the long-term investments already.”
Lithium production typically involves either mining hard rocks or extracting salts through brines. Both are water intensive processes with considerable environmental tolls. Scientists at Texas A&M University are now developing a new approach involving the deployment of tiny, fish-like swimming nanorobots that capture lithium ions from seawater. Backed by a $1 million Energy Department grant, it’s among more than a dozen projects the agency is supporting in a bid to bolster domestic critical mineral supplies. “Unlike traditional mining that digs up land or pumps brine from underground and requires massive amounts of energy, these autonomous micro/nanorobots move freely through seawater to harvest lithium with virtually zero infrastructure footprint,” Jingjing Qiu, one of the mechanical engineers leading the research, said in a statement.

Talking with National Grid’s Matthew Satterwhite about his new report with S&P Global.
This week’s conversation is with Matthew Satterwhite, head of U.S. policy for National Grid. This week National Grid released a report in collaboration with S&P Global I found noteworthy amidst the data center backlash, asserting that building new transmission lines can potentially reduce consumer costs. I reached out asking if we could chat about how this argument leans into the fight over hyperscale infrastructure. I found our conversation illuminating and educational.
The following Q&A was lightly edited for clarity.
Why did you make this report?
It’s all focused on our customers. We’re always looking to find ways to make sure we can provide our service in the most affordable way possible, the most efficient way possible, and we always think of transmission, but it’s fallen out of favor recently. There’s so much demand with large loads, data centers, advanced manufacturing, reshoring. There’s such a need, and a lot of the debate has been focused on what we need on the generation side. We think transmission is an answer, as well.
We focused on what we have control over — since we’re in deregulated states, the only generation we’re doing is to help states reach their renewable goals. It’s a real page-turner. We really get to the core of everything.
Can we lower customer bills with transmission? This report actually showed us that’s a good investment and helps with the resource adequacy and the constraint problems we have in the Northeast. You can bring cheaper electricity in.
With respect to concerns for everyday consumers, how much do you feel like new transmission might alleviate ordinary Americans’ concerns about rising energy prices?
When you look at the demand that’s coming, the projection is that by 2035, we’ll have to add 45 gigawatts, currently. We’re on that path right now. Transmission alone isn’t going to meet that, but the question is, how do we temper that down? What do we do as National Grid to help alleviate the need for all that demand? Can we get that somewhere else rather than in the region by building generation? It's a different version of all of the above. It’s not a generation single answer or a transmission single answer. We think transmission is a big part of that.
This also allows you to bring in cleaner energy from other places. The more robust the network is, you can have energy in different places and bring that in. It replaces the need for some of the generation to be built and pays for itself by creating a cheaper return for customers adding this.
How much of the data center backlash is affecting your transmission project planning calculus? How is it changing what lines are built in the country?
We’re focused on how we can provide the cheapest service for our customers and physics. It’s science and long-term planning. We don’t have the luxury — we can’t follow, this month we’re thinking something, someone got mad, and so we’re thinking something else. We study a lot of science and physics to figure out how to build the grid.
Do you feel like the average Joe Schmoe American sees transmission as making their life less expensive and making their electricity more reliable?
I think there’s frustration and a lack of understanding about the industry overall. There’s fear of the unknown. Are data centers really driving everything that’s happening? That’s where I think, with reports like this, the benefit of it will be that people will read this and see there’s other things we can do to address the load that we need, something different than building a bunch of generation plants.
How do the question marks around whether data centers get built affect transmission planning? How much harder is the backlash making your job?
It’s a science question. Do we do a bunch of work and then nothing happens? That’s why states put their policies out. There’s multiple studies you go through with a region and with a utility. I think that’s one reason why you see states slowing down, to make sure the policy is in check so people don’t do work they don’t need to do. It’s about having the policy to make sure, if you’re studying something, you’re doing it with a purpose.
Plus more of the week’s biggest development fights.
1. Clark County, Nevada – The first data center approved on federal lands has hit a legal brick wall.
2. Jackson County, Missouri – We have yet another high-profile case of a city councilor losing their job over voting for a data center, and this one’s a doozy.
3. Utah – What’s it take for the Bureau of Land Management to approve a big transmission line for zero-emission energy generation these days? Geothermal, baby.
4. Huntsville, Alabama – You can’t even build a tiny battery storage facility in the middle of Alabama anymore.
Where temporary moratoria could happen next.
Brace yourself for more statewide data center moratoria.
So far there are only two full state-wide blocks on data center permits, in New York and Texas. At least fifteen states have moratorium legislation in the pipeline, but few if any of those bills stand a chance of becoming law in the short term. Here are five states, however, where a broad development pause may gain momentum in the next year or two — and all of them are crucial to watch this November.
If you blinked you may have missed it: New Hampshire Governor Kelly Ayotte, a Republican, said she wants to enact a statewide data center moratorium.
Ayotte first came out in support of a pause last month at a Rotary Club meeting, declaring, “It does not make any sense at all to site a data center in New Hampshire.” She also reportedly plans to include a moratorium proposal in her upcoming 2027 fiscal budget. New Hampshire’s legislative sessions occur in the first half of the year, so we won’t see action on a moratorium bill this fall. But Ayotte’s statements suggest the Granite State — which is controlled by the GOP — could pivot to a pause very soon.
New Hampshire has very few data centers. Like, almost none. Only two project fights exist in the Heatmap Pro database, both in Portsmouth, and each has been canceled amidst opposition. Ayotte’s remarks were prompted by the fight against a hyperscale project being studied in the small town of Bow at a former coal plant that closed in late 2025.
None of this should surprise anyone familiar with New England NIMBYs. A New Hampshire moratorium also makes sense given the state’s proximity to Maine, which almost had one of its own. Ayotte, who is up for re-election this year, is likely looking at the political fortunes of Governor Janet Mills and trying to avoid potholes ahead of a likely blue wave hitting her state.
This week, Arizona Attorney General Kris Mayes, a Democrat, came out in support of a statewide data center moratorium.
Mayes told Arizonans in a public statement on Monday that she wants to avoid undue strain on the electric grid and adding to the burden of water cuts led by the Trump administration. Phoenix, where opposition grows by the day, seems to be the primary reason. This shouldn’t in any way be a surprise given the backlash to these projects, which in Arizona’s case is rooted in legitimate water security concerns.
One of the first high-profile data center conflicts I ever learned about was in Arizona: Project Blue, which had to move on from the city of Tucson after officials voted it down last summer. That led Amazon to bail from the facility, though it’s still under development elsewhere on county land. Locals are deeply concerned about the water impacts.
Ordinarily an attorney general wouldn’t have any sway on legislative or executive policy, but the state is already quite receptive to restricting data center development. Governor Katie Hobbs has enacted a three-year pause on tax abatements for data centers, and in response to requests for comment on Mayes’ statement, has told media she’s working on more policies targeting the sector. Hobbs has said she will do more in the following legislative session, but it’s not clear what.
The real decisive action here is probably going to be legislation, and that will depend on the reception any moratorium finds with Republicans in the state legislature, which is typically split in this purple state. The Arizona GOP is quite pro-industry, and Mayes’ opponent in her race for re-election opposes restricting data center construction.
You really should get to know the name Cindy Holscher for the next two months.
Holscher, a state senator, won a surprise upset victory in the Democratic gubernatorial primary this year, and currently sits within a one-point margin of her Republican opponent. How’d she get the nom? By calling for a statewide data center moratorium. “It reminds me of when the automobile manufacturers had to put seatbelts into their cars,“ Holscher told MSNOW after she won the primary. “We as a people and as a state just need to make sure there are guardrails in place.”
Kansas politics are weird. The state is best known as a conservative ideological bastion that’s pro-business. Full Republican control of the Kansas government during the Obama era led to significant social services cuts most closely associated with former Governor Sam Brownback. But after that, Kansans seemed to like moderate Democratic governors, electing Laura Kelly in 2022. Kelly is now term limited out of office.
Kansas already has a colorful patchwork of local data center and renewable energy restrictions. Land use is a big deal in this agricultural behemoth. Should Holscher win in a blue wave year, she would have a mandate to enact a statewide moratorium. Still, Republicans control the legislature, and that’s unlikely to change. My major questions are, should Holscher win, would the GOP in state government listen to Holscher’s request? Or can she do this through the executive branch?
Politics nerds are obsessing over Ohio right now. There, Trump acolyte Vivek Ramaswamy is neck-and-neck in the polls for governor with a Democratic candidate who backs a “conditional” data center moratorium: Amy Acton.
What’s a conditional moratorium? It’s in the eye of the beholder, really. Technically speaking, Governor Josh Shapiro instituted a conditional moratorium in Pennsylvania, where data center projects cannot get permits unless they meet very specific standards set by the governor himself. Shapiro did it through executive action, but in this case, it’s unclear whether the moratorium will be codified through that process or through law.
Should Acton win — or if former Senator Sherrod Brown defeats sitting Senator Jon Husted in the U.S. Senate race — I anticipate major legislative action on data centers in Ohio. Republicans there have essentially permanent control of the state legislature, and they’ve historically been pro-data center. But the freakout over opposition to artificial intelligence and hyperscalers in the senate race specifically has spooked national Republicans, who think it provided the opening Brown needed to potentially win back his seat. Acton and Brown’s political fortunes appear to be wedded to one another, linked to a general angst in the American public.
Every top 5 list needs a wild card, and mine is Oklahoma.
Currently, there’s minimal risk of a data center moratorium. I might’ve had this state higher on my list had Gentner Drummond won the runoff for the GOP gubernatorial primary, given his proclivity to side with anti-renewables activists who also oppose data centers. Instead, likely future governor Mike Mazzei is running on a more moderate, Trump-friendly approach to data centers centered on maintaining industry growth while protecting ratepayers from new infrastructure costs. His opponent, Cyndi Munson, supports a one-year moratorium.
I consider Oklahoma’s odds of having a data center moratorium about equal to the chance of a statewide wind energy ban. Momentum for anti-wind legislation began in the state legislature, and I expect the same to happen with data centers. But unlike the wind industry, which has enormous power in the state, data centers are still a nascent industry. This is a place that may take about two or three years to manifest full cultural upheaval over these projects.
