One of the most vulnerable states in the U.S. wants nothing to do with “climate change.”

The Biden administration loves a hub. There are the hydrogen hubs, the direct air capture hubs, and now there are the tech hubs. Established as a part of the CHIPS and Science Act of 2022, the $10 billion program has so far seeded 12 such hubs across the country. Four of these are focused on clean energy and sustainability, and one is located in the great state of Florida, which recently passed legislation essentially deleting the words “climate change” from state law.
The South Florida ClimateReady Tech Hub did not, in the end, eliminate climate from its name. But while Governor Ron DeSantis might not approve, the federal government didn’t seem to mind, as the Department of Commerce’s Economic Development Administration awarded the hub $19.5 million to “advance its global leadership in sustainable and resilient infrastructure.”
“Regardless of how you feel about the word climate or the words climate change, what I have found in this process is what deeply resonates with folks is that their relationship with water is changing,” Francesca de Quesada Covey, chief of economic innovation and development for Miami-Dade County, told me.
Sea levels around Florida have risen about 8 inches since 1950, and the rate of rise is only accelerating, putting the state’s extensive, low-lying coastlines at high risk for flooding and, eventually, total submersion. The United Nations Intergovernmental Panel on Climate Change estimates that by 2100, average sea levels will have risen between 1.4 and 2.8 feet, with more drastic scenarios possible if little is done to curb emissions.
Covey, who grew up in Miami, said everyone agrees there are simply more puddles and flooded roads to navigate than when she was a kid. “So there is an understanding that regardless of how you think it happened, or why you think it happened, that our everyday life is harder because the environment around us is changing.”
This narrative, she believes, can help form a basis of bipartisan support for Florida’s hub, which she told me has three technical focus areas: limiting coastal hazards due to sea level rise and extreme weather events, implementing energy efficient technologies, and building resilient structures using low-carbon concrete and cement. South Florida, Covey said, is the perfect place to undertake these projects, as the state has been investing in climate adaptation and mitigation since 1992, when Hurricane Andrew touched down in Miami-Dade County, causing $25 billion in damages. Since then, she says the state’s universities have been churning out climate tech intellectual property.
“We’re seeing the IP grow 10% year-over-year over the last few years,” Covey said. Nine colleges and universities are tech hub partners, with the bulk of the funding going to Florida International University, which will receive $10.3 million to help scale up low-carbon concrete tech, establish an infrastructure innovation center, and improve upon industry building codes and standards. Miami Tech Works, which aims to build a pipeline of tech talent in South Florida, is set to receive $6 million for workforce development programs while the Miami-Dade County government will get $3.2 million for governance and oversight. Two private companies working on advanced concrete products, Titan America and Carbon Limit, are also getting a portion of the FIU funding — $740,000 for Carbon Limit and an undisclosed amount for Titan.
Tim Sperry, CEO of Carbon Limit, is used to getting questions about why he based his early-stage startup out of Florida, his home state. “Great that you guys are a climate tech company, but why would you be in South Florida?” Sperry said people wonder. “Florida at all was a bad look for climate tech companies until this hub actually came together,” he told me. Since the hub was initially announced last October, Sperry says he’s seen more money for climate tech flowing into the state.
Carbon Limit has a patented powder additive for concrete mixes, which enhances concrete’s natural ability to absorb CO2 from the atmosphere and sequester it permanently, thereby reducing the carbon intensity of built infrastructure such as buildings and roads. So far the company has worked with the Minnesota Department of Transportation to pave a section of interstate highway, and with Google to pave a portion of its campus. Carbon Limit raised a $1 million pre-seed round two years ago, and its business model revolves around licensing the formula for its additive to concrete producers.
Sperry sees Florida as “ground zero” for climate-related natural disasters, and thus a natural home for this type of technology. When he worked in Miami, he saw people kayaking down the streets during king tides, and found crabs in his office after floods. “They actually raised the road four feet and put pumps and did all this stuff down there. So I think, why shouldn’t it be South Florida?” he asked, “Short of the government stuff …”
Ah yes, the government stuff. While DeSantis hasn’t weighed in publicly on the ClimateReady Tech Hub, Covey said the state’s DeSantis-appointed Chief Resilience Officer, Wesley Brooks, is supportive. Brooks helped craft the “state support” section of the hub’s application, which calls the Office of Resilience “an advocate for the Hub and an ally in providing technical guidance to local governments.”
Climate tech startups can’t eat guidance, however. If the hub is going to accomplish its lofty technical and workforce development goals, it’s going to need a lot more than $19.5 million, and a lack of state-level support could make securing additional funds that much more difficult.
“We requested $70 million,” Covey told me, the maximum amount of federal funding that tech hubs could apply for. Most of the other hubs received between $40 million and $50 million, putting the South Florida hub at the small end of the bunch. Covey said the county didn’t receive feedback as to why. “The way that we’re looking at $19.5 [million] is that this is our first investment tranche. We will be going back to the federal government. We will be going back to private funders. We will be going back to philanthropic funders in order to achieve our metrics,” she told me.
Ultimately, Miami-Dade County wants to leverage the ClimateReady Tech Hub to create 23,000 green jobs with an average base salary of $87,000 over a 10-year period. Thus far, Miami-Dade has raised an additional $500,000 — not nothing, but far from its ultimate goal of raising another $50 million. The increasing probability of a Trump win in November could put future federal funding for the hub at the whims of a notoriously mercurial and climate-adverse cabinet.
But if the tech hub does achieve its goals, Covey estimates the payoff will be huge, adding $41 billion to the region’s GDP. Given all the growth South Florida has seen over the last four years, with entrepreneurs and venture capitalists flooding into the region during the pandemic, Covey thinks the hub’s got a real shot of securing the money it needs. She even told me she views South Florida as “the most competitive place when it comes to climate technology.”
When I noted that the San Francisco Bay Area might beg to differ, Covey emphasized how much it matters that Miami-Dade County is experiencing the impacts of climate change in real time. “The Bay Area doesn’t have those sort of real life testing conditions that we have here. We have $3.5 trillion exposed to climate change right now,” she told me, citing a figure from a National Wildlife Federation report showing that out of all the cities in the world, Miami stands to lose the most from coastal flooding. In other words, in South Florida climate tech isn’t a matter of theoretical tinkering and ideating. As Covey says, “Our economy depends on it.”
Editor’s note: This story has been updated to correct the name of the chief of economic innovation and development for Miami-Dade County and the target average salary for new jobs created by the hub.

The fourth-generation gas-cooled reactor company ZettaJoule is setting up shop at an unnamed university.
The appeal of next-generation nuclear technology is simple. Unlike the vast majority of existing reactors that use water, so-called fourth-generation units use coolants such as molten salt, liquid metal, or gases that can withstand intense heat such as helium. That allows the machines to reach and maintain the high temperatures necessary to decarbonize industrial processes, which currently only fossil fuels are able to reach.
But the execution requirements of these advanced reactors are complex, making skepticism easy to understand. While the U.S., Germany, and other countries experimented with fourth-generation reactors in earlier decades, there is only one commercial unit in operation today. That’s in China, arguably the leader in advanced nuclear, which hooked up a demonstration model of a high-temperature gas-cooled reactor to its grid two years ago, and just approved building another project in September.
Then there’s Japan, which has been operating its own high-temperature gas-cooled reactor for 27 years at a government research site in Ibaraki Prefecture, about 90 minutes north of Tokyo by train. Unlike China’s design, it’s not a commercial power reactor. Also unlike China’s design, it’s coming to America.
Heatmap has learned that ZettaJoule, an American-Japanese startup led by engineers who worked on that reactor, is now coming out of stealth and laying plans to build its first plant in Texas.
For months, the company has quietly staffed up its team of American and Japanese executives, including a former U.S. Nuclear Regulatory Commission official and a high-ranking ex-administrator from the industrial giant Mitsubishi. It’s now preparing to decamp from its initial home base in Rockville, Maryland, to the Lone Star State as it prepares to announce its debut project at an as-yet-unnamed university in Texas.
“We haven’t built a nuclear reactor in many, many decades, so you have only a handful of people who experienced the full cycle from design to operations,” Mitsuo Shimofuji, ZettaJoule’s chief executive, told me. “We need to complete this before they retire.”
That’s where the company sees its advantage over rivals in the race to build the West’s first commercial high-temperature gas reactor, such as Amazon-backed X-energy or Canada’s StarCore nuclear. ZettaJoule’s chief nuclear office, Kazuhiko Kunitomi, oversaw the construction of Japan’s research reactor in the 1990s. He’s considered Japan’s leading expert in high-temperature gas reactors.
“Our chief nuclear officer and some of our engineers are the only people in the Western world who have experience of the whole cycle from design to construction to operation of a high temperature gas reactor,” Shimofuji said.
Like X-energy’s reactor, ZettaJoule’s design is a small modular reactor. With a capacity of 30 megawatts of thermal output and 12 megawatts of electricity, the ZettaJoule reactor qualifies as a microreactor, a subcategory of SMR that includes anything 20 megawatts of electricity or less. Both companies’ reactors will also run on TRISO, a special kind of enriched uranium with cladding on each pellet that makes the fuel safer and more efficient at higher temperatures.
While X-energy’s debut project that Amazon is financing in Washington State is a nearly 1-gigawatt power station made up of at least a dozen of the American startup’s 80-megawatt reactors, ZettaJoule isn’t looking to generate electricity.
The first new reactor in Texas will be a research reactor, but the company’s focus is on producing heat. The reactor already working in Japan, which produces heat, demonstrates that the design can reach 950 degrees Celsius, roughly 25% higher than the operating temperature of China’s reactor.
The potential for use in industrial applications has begun to attract corporate partners. In a letter sent Monday to Ted Garrish, the U.S. assistant secretary of energy in charge of nuclear power — a copy of which I obtained — the U.S. subsidiary of the Saudi Arabian oil goliath Aramco urged the Trump administration to support ZettaJoule, and said that it would “consider their application to our operations” as the technology matures. ZettaJoule is in talks with at least two other multinational corporations.
The first new reactor ZettaJoule builds won’t be identical to the unit in Japan, Shimofuji said.
“We are going to modernize this reactor together with the Japanese and U.S. engineering partners,” he said. “The research reactor is robust and solid, but it’s over-engineered. What we want to do is use the safety basis but to make it more economic and competitive.”
Once ZettaJoule proves its ability to build and operate a new unit in Texas, the company will start exporting the technology back to Japan. The microreactor will be its first product line.
“But in the future, we can scale up to 20 times bigger,” Shimofuji said. “We can do 600 megawatts thermal and 300 megawatts electric.”
Another benefit ZettaJoule can tap into is the sweeping deal President Donald Trump brokered with Japanese Prime Minister Sanae Takaichi in October, which included hundreds of billions of dollars for new reactors of varying sizes, including the large-scale Westinghouse AP1000. That included financing to build GE Vernova Hitachi Nuclear Energy’s 300-megawatt BWRX-300, one of the West’s leading third-generation SMRs, which uses a traditional water-cooled design.
Unlike that unit, however, ZettaJoule’s micro-reactor is not a first-of-a-kind technology, said Chris Gadomski, the lead nuclear analyst at the consultancy BloombergNEF.
“It’s operated in Japan for a long, long time,” he told me. “So that second-of-a-kind is an attractive feature. Some of these companies have never operated a reactor. This one has done that.”
A similar dynamic almost played out with large-scale reactors more than two decades ago. In the late 1990s, Japanese developers built four of GE and Hitachi’s ABWR reactor, a large-scale unit with some of the key safety features that make the AP1000 stand out compared to its first- and second-generation predecessors. In the mid 2000s, the U.S. certified the design and planned to build a pair in South Texas. But the project never materialized, and America instead put its resources into Westinghouse’s design.
But the market is different today. Electricity demand is surging in the near term from data centers and in the long term from electrification of cars and industry. The need to curb fossil fuel consumption in the face of worsening climate change is more widely accepted than ever. And China’s growing dominance over nuclear energy has rattled officials from Tokyo to Washington.
“We need to deploy this as soon as possible to not lose the experienced people in Japan and the U.S.,” Shimofuji said. “In two or three years time, we will get a construction permit ideally. We are targeting the early 2030s.”
If every company publicly holding itself to that timeline is successful, the nuclear industry will be a crowded field. But as history shows, those with the experience to actually take a reactor from paper to concrete may have an advantage.
It’s now clear that 2026 will be big for American energy, but it’s going to be incredibly tense.
Over the past 365 days, we at The Fight have closely monitored numerous conflicts over siting and permitting for renewable energy and battery storage projects. As we’ve done so, the data center boom has come into full view, igniting a tinderbox of resentment over land use, local governance and, well, lots more. The future of the U.S. economy and the energy grid may well ride on the outcomes of the very same city council and board of commissioners meetings I’ve been reporting on every day. It’s a scary yet exciting prospect.
To bring us into the new year, I wanted to try something a little different. Readers ask me all the time for advice with questions like, What should I be thinking about right now? And, How do I get this community to support my project? Or my favorite: When will people finally just shut up and let us build things? To try and answer these questions and more, I wanted to give you the top five trends in energy development (and data centers) I’ll be watching next year.
The best thing going for American renewable energy right now is the AI data center boom. But the backlash against developing these projects is spreading incredibly fast.
Do you remember last week when I told you about a national environmental group calling for data center moratoria across the country? On Wednesday, Senator Bernie Sanders called for a nationwide halt to data center construction until regulations are put in place. The next day, the Working Families Party – a progressive third party that fields candidates all over the country for all levels of government – called for its candidates to run in opposition to new data center construction.
On the other end of the political spectrum, major figures in the American right wing have become AI skeptics critical of the nascent data center buildout, including Florida Governor Ron DeSantis, Missouri Senator Josh Hawley, and former Trump adviser Steve Bannon. These figures are clearly following the signals amidst the noise; I have watched in recent months as anti-data center fervor has spread across Facebook, with local community pages and groups once focused on solar and wind projects pivoting instead to focus on data centers in development near them.
In other words, I predicted just one month ago, an anti-data center political movement is forming across the country and quickly gaining steam (ironically aided by the internet and algorithms powered by server farms).
I often hear from the clean energy sector that the data center boom will be a boon for new projects. Renewable energy is the fastest to scale and construct, the thinking goes, and therefore will be the quickest, easiest, and most cost effective way to meet the projected spike in energy demand.
I’m not convinced yet that this line of thinking is correct. But I’m definitely sure that no matter the fuel type, we can expect a lot more transmission development, and nothing sparks a land use fight more easily than new wires.
Past is prologue here. One must look no further than the years-long fight over the Piedmont Reliability Project, a proposed line that would connect a nuclear power plant in Pennsylvania to data centers in Virginia by crossing a large swathe of Maryland agricultural land. I’ve been covering it closely since we put the project in our inaugural list of the most at-risk projects, and the conflict is now a clear blueprint.
In Wisconsin, a billion-dollar transmission project is proving this thesis true. I highly recommend readers pay close attention to Port Washington, where the release of fresh transmission line routes for a massive new data center this week has aided an effort to recall the city’s mayor for supporting the project. And this isn’t even an interstate project like Piedmont.
While I may not be sure of the renewable energy sector’s longer-term benefits from data center development, I’m far more confident that this Big Tech land use backlash is hitting projects right now.
The short-term issue for renewables developers is that opponents of data centers use arguments and tactics similar to those deployed by anti-solar and anti-wind advocates. Everyone fighting data centers is talking about ending development on farmland, avoiding changes to property values, stopping excess noise and water use, and halting irreparable changes to their ways of life.
Only one factor distinguishes data center fights from renewable energy fights: building the former potentially raises energy bills, while the latter will lower energy costs.
I do fear that as data center fights intensify nationwide, communities will not ban or hyper-regulate the server farms in particular, but rather will pass general bans that also block the energy projects that could potentially power them. Rural counties are already enacting moratoria on solar and wind in tandem with data centers – this is not new. But the problem will worsen as conflicts spread, and it will be incumbent upon the myriad environmentalists boosting data center opponents to not accidentally aid those fighting zero-carbon energy.
This week, the Bureau of Land Management approved its first solar project in months: the Libra facility in Nevada. When this happened, I received a flood of enthusiastic and optimistic emails and texts from sources.
We do not yet know whether the Libra approval is a signal of a thaw inside the Trump administration. The Interior Department’s freeze on renewables permitting decisions continues mostly unabated, and I have seen nothing to indicate that more decisions like this are coming down the pike. What we do know is that ahead of a difficult midterm election, the Trump administration faces outsized pressure to do more to address “affordability,” Democrats plan to go after Republicans for effectively repealing the Inflation Reduction Act and halting permits for solar and wind projects, and there’s a grand bargain to be made in Congress over permitting reform that rides on an end to the permitting freeze.
I anticipate that ahead of the election and further permitting talks in Congress, the Trump administration will mildly ease its chokehold on solar and wind permits because that is the most logical option in front of them. I do not think this will change the circumstances for more than a small handful of projects sited on federal lands that were already deep in the permitting process when Trump took power.
It’s impossible to conclude a conversation about next year’s project fights without ending on the theme that defined 2025: battery fire fears are ablaze, and they’ll only intensify as data centers demand excess energy storage capacity.
The January Moss Landing fire incident was a defining moment for an energy sector struggling to grapple with the effects of the Internet age. Despite bearing little resemblance to the litany of BESS proposals across the country, that one hunk of burning battery wreckage in California inspired countless communities nationwide to ban new battery storage outright.
There is no sign this trend will end any time soon. I expect data centers to only accelerate these concerns, as these facilities can also catch fire in ways that are challenging to address.
Plus a resolution for Vineyard Wind and more of the week’s big renewables fights.
1. Hopkins County, Texas – A Dallas-area data center fight pitting developer Vistra against Texas attorney general Ken Paxton has exploded into a full-blown political controversy as the power company now argues the project’s developer had an improper romance with a city official for the host community.
2. La Plata County, Colorado – This county has just voted to extend its moratorium on battery energy storage facilities over fire fears.
3. Dane County, Wisconsin – The city of Madison appears poised to ban data centers for at least a year.
4. Goodhue County, Minnesota – The Minnesota Center for Environmental Advocacy, a large environmentalist organization in the state, is suing to block a data center project in the small city of Pine Island.
5. Hall County, Georgia – A data center has been stopped down South, at least for now.
6. Dukes County, Massachusetts – The fight between Vineyard Wind and the town of Nantucket seems to be over.
