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.

As always, it’s the lawyers who are the real winners.
Things are never simple when it comes to tariffs. While the Supreme Court’s decision on Friday finding that the International Emergency Economic Powers Act, better known as IEEPA, did not authorize Donald Trump’s “fentanyl” tariffs on Canada, China, and Mexico, and “reciprocal” tariffs on the rest of the world was unambiguous, tariff policy is still complex and evolving.
Already Trump has said he would use a separate authority to impose a 10% global tariff that can extend as long as 150 days. The administration is also pursuing a number of investigations that will likely result in new tariffs under more well-established authorities.
And none of this changes the fact that the clean energy industry has been tangling with tariffs for years and will continue to do so after today. While companies will likely experience some relief, it may or may not make a material difference.
Here are just some of the factors in play:
One thing today’s court ruling did not clarify is how companies should go about recovering the funds they’ve already paid toward these tariffs — which, if the tariffs were illegal all along, is money they’re now owed.
The confusion goes deeper than the mere mechanism, however, because while developers may be feeling the impact from tariffs in terms of higher prices from their suppliers — for, say, solar modules — it’s the suppliers they’ve contracted with who are likely entitled to refunds.
“The existing tariffs that are in place as of the date of that contract signing are built into the contract price. And then there’s a provision in there that if new tariffs are introduced, the supplier is entitled to readjust,” Stefan Reisinger, a partner at the law firm Norton Rose Fulbright, told me.
While contracts often have provisions for what to do when a new tariff comes in, they don’t tend to have provisions for tariffs being refunded.
“The agreements don’t have provisions in them that actually deal with the prospect of tariffs being ruled invalid with the supplier getting a refund, so they’re technically not obligated under the contract to flow those refunds down,” Reisinger said.
“I had some preliminary discussions today with suppliers that are in that position, and for business reasons, they’ll likely pass along some portion of the refund,” he added. “There’s going to be countless disputes over who gets the refund and how much.”
The clean energy supply chain is global. Especially for the backbone of the energy transition — solar and storage — China dominates. For some components, like wafers, China has a near monopoly on production. Over 90% of the market for solar cells comes from China. The U.S. lacked even the capacity to produce all components of a solar system domestically until late last year.
Trade restrictions on solar go far beyond the baseline tariffs and the China-specific tariffs addressed in today’s Supreme Court decision, however. There are China-specific restrictions and other tariffs imposed on companies that tried to evade them by setting up manufacturing abroad. The Trump administration is investigating polysilicon, a first step to imposing tariffs. The Biden administration extended and increased tariffs on Chinese solar cells and modules that had been first imposed in 2018. Meanwhile, another set of solar tariffs expired earlier this month.
Still, “I think the biggest impact of the ruling will be for solar and batteries, because they face some of the largest tariffs, and so we’ll see the biggest cost reductions,” Oliver Kerr, North America managing director at Aurora Energy Research, told me. Some manufacturers have already made refund requests — though again, who knows how that will play out.
Solar investors responded with cautious optimism to the court’s tariff ruling. Shares in Canadian Solar, a solar manufacturing company that has been whipped around by tariffs, shot up after the decision was released.
Other solar manufacturers have a more ambiguous relationship to tariffs. First Solar, the leading U.S. solar manufacturer, took a hit following the initial “liberation day” tariffs, as they affected the company’s operations in Vietnam, India, and Malaysia. In regulatory filings with the Securities and Exchange Commission, First Solar has said that, “as it pertains to the countries where we manufacture solar modules, reciprocal tariff rates apply to Vietnam (20%), India (25%), and Malaysia (19%),” and so “as a result, our operating results have and may continue to be adversely impacted by these tariffs.” (Since “liberation day,” the Trump administration has reached trade deals with Vietnam and India.)
When it comes to the tariffs on China, though, First Solar has a clear point of view: They’re good. “Our operating results could be adversely impacted if the IEEPA tariffs on China were to be terminated or reduced,” the company has said in its regulatory filings.
A similar story applies to batteries. China dominates the supply chains for the minerals used in batteries, including cobalt, lithium, and graphite, particularly in the refining stage. Much of the anode graphite material manufacturing sector simply moved to Indonesia in response to the tariffs on China, according to battery analyst Henry Sanderson.
At the same time, battery manufacturers and developers of battery energy storage systems will want to comply with foreign entities of concern rules, which restrict the use of Chinese material and Chinese companies’ involvement in the supply chain for technologies that receive tax credits.
“For storage in particular, they will have the foreign entity of concern, so they will still have to source a meaningful proportion of the content domestically,” Kerr told me. “That matters a little more for batteries because batteries still have access to tax credits through the early 2030s and those tax credits are pretty valuable.”
Another wrinkle: Unrelated to the Trump “reciprocal” tariffs, the Department of Commerce last week finalized punishingly high tariff rates on Chinese active anode material as part of an antidumping investigation.
Many emerging technologies are likely to benefit from tariffs being lifted.
“Anything that relies on industrial inputs, I think there’s a big impact here,” David Yellen, director of climate policy innovation at the Clean Air Task Force, told me.
While protection can work for some industries like steel and aluminum, it doesn’t help much for anyone — including manufacturers — who have to use inputs.
“The blanket policy was that putting tariffs on downstream products and inputs doesn’t actually really protect your domestic industry. It raises prices across the board,” he said, pointing to advanced nuclear and geothermal as high tech industrial processes that have a global supply chain. Drill bits, sensors, and power electronics may all see some price relief.
“To the extent that removing some of these blanket tariffs in the aggregate allows the input prices to go down,” Yellen told me, “I think it may benefit a lot of the capital intensive technologies.”
The sale of Ravenswood Generating Station closed at the end of January.
New York City’s largest fossil fuel-fired power plant has changed hands. The Ravenswood Generating Station, which provides more than 20% of the city’s generation capacity, was sold by its former parent company LS Power to NRG, an energy company headquartered in Texas that owns power plants throughout the country.
It’s not yet clear what this means for “Renewable Ravenswood,” the former owner’s widely-publicized plans to convert the site into a clean energy hub. Prior to the sale, those plans were hanging by a thread. NRG did not respond to detailed questions about whether it will abandon or advance that vision.
“Ravenswood has been an important part of powering New York City for decades, and we recognize how much the facility matters to the surrounding community and the region,” a spokesperson for the company told me in an email. “We’ve begun engaging with community stakeholders and look forward to continuing those conversations in the months ahead. Our leadership team is carefully reviewing all relevant information and is taking a thoughtful, measured approach to any future decisions.”
Ravenswood is made up of four generating units: a natural gas combined cycle plant built in 2004, and three steam generators built in the 1960s that run mostly on natural gas, though sometimes also on oil. The plant is responsible for a sizable chunk of the city’s climate footprint. In 2023, the most recent year for which data is available, the plant emitted nearly 1.3 million metric tons of CO2, or about 8% of the city’s emissions from electricity production.
The Renewable Ravenswood concept was largely celebrated by the surrounding community, which includes two of the largest public housing projects in the country and suffers from disproportionately high rates of chronic respiratory diseases like asthma. The plan, which a local subsidiary of LS Power called Rise Light and Power proposed in 2022, entailed replacing the plant’s three 1960s steam generators with a combination of offshore wind, batteries, and renewable energy delivered from upstate New York via new power lines.
By last year, however, the plan was increasingly looking like a distant dream. Its centerpiece was a proposed offshore wind farm called Attentive Energy, but the project has been on ice since 2024, with little chance of moving forward under the Trump administration. This past November, New York regulators rejected a proposed transmission line that would have connected Ravenswood to a hypothetical future offshore wind development, primarily because there was no longer any such development in progress. Earlier this week, state energy regulators delivered yet another blow to potential offshore wind development when they decided not to solicit offers from for new projects to enter the state’s energy market.
Battery development has also had a rocky few years in New York State, which has affected Ravenswood’s transition. Rise Light and Power initially proposed building a 316-megawatt battery project on the site in 2019, but it has yet to break ground. The former CEO, Clint Plummer, previously told me that the company was waiting on New York State regulators to open up their anticipated battery solicitation, which would enable the project to bid into the New York energy market, before building the project. That solicitation opened last July, but it’s unclear whether the company submitted a bid. NRG did not respond to a question about this.
NRG first announced its plans to buy a fleet of natural gas plants — 18 in total — from LS Power in May 2025. Ravenswood was not mentioned in the press release or investor materials, however. “We're acquiring these assets at a significant discount to new build cost, at an attractive valuation, and at the strategically opportune time to be adding high-quality, difficult-to-replicate resources into our portfolio as the sector enters into a period of sustained demand growth,” NRG’s CEO Lawrence Coben told investors at the time.
The purchase was subject to regulatory approval and officially closed a few weeks ago, on January 30. Documents filed with the Securities and Exchange Commission confirm that Ravenswood was part of the deal. Documents filed with the New York Public Service Commission describe the terms in more detail, but they do not mention the proposed transition of the site to a clean energy hub.
Local officials, community groups, and tenant associations were deeply involved in fleshing out the Renewable Ravenswood vision. The Queens Borough President worked with the former owner on a multiyear report called “Reimagine Ravenswood,” released last summer, based on extensive engagement with the community, including public workshops, focus groups, interviews with local leaders, and a community survey. The report is evidence of high hopes the community has for the site’s transition, describing the potential to create jobs, expand public space, and generally increase investment in the neighborhood.
I reached out to many of the local elected officials and community groups that have publicly supported Renewable Ravenswood to ask if they were aware of the sale and whether NRG had made any commitments in regard to the transition plan. Just one responded. State Senator Kristen Gonzalez’s office told me they were aware of the sale, but declined to comment further.
Heron Power and DG Matrix each score big funding rounds, plus news for heat pumps and sustainable fashion.
While industries with major administrative tailwinds such as nuclear and geothermal have been hogging the funding headlines lately, this week brings some variety with news featuring the unassuming but ever-powerful transformer. Two solid-state transformer startups just announced back-to-back funding rounds, promising to bring greater efficiency and smarter services to the grid and data centers alike. Throw in capital supporting heat pump adoption and a new fund for sustainable fashion, and it looks like a week for celebrating some of the quieter climate tech solutions.
Transformers are the silent workhorses of the energy transition. These often-underappreciated devices step up voltage for long-distance electricity transmission and step it back down so that it can be safely delivered to homes and businesses. As electrification accelerates and data centers race to come online, demand for transformers has surged — more than doubling since 2019 — creating a supply crunch in the U.S. that’s slowing the deployment of clean energy projects.
Against this backdrop, startup Heron Power just raised a $140 million Series B round co-led by Andreessen Horowitz and Breakthrough Energy Ventures to build next-generation solid state transformers. The company said its tech will be able to replace or consolidate much of today’s bulky transformer infrastructure, enabling electricity to move more efficiently between low-voltage technologies like solar, batteries, and data centers and medium-voltage grids. Heron’s transformers also promise greater control than conventional equipment, using power electronics and software to actively manage electricity flows, whereas traditional transformers are largely passive devices designed to change voltage.
This new funding will allow Heron to build a U.S.manufacturing facility designed to produce around 40 gigawatts of transformer equipment annually; it expects to begin production there next year. This latest raise follows quickly on the heels of its $38 million Series A round last May, reflecting hunger among customers for more efficient and quicker to deploy grid infrastructure solutions. Early announced customers include the clean energy developer Intersect Power and the data center developer Crusoe.
It’s a good time to be a transformer startup. DG Matrix, which also develops solid-state transformers, closed a $60 million Series A this week, led by Engine Ventures. The company plans to use the funding to scale its manufacturing and supply chain as it looks to supply data centers with its power-conversion systems.
Solid-state transformers — which use semiconductors to convert and control electricity — have been in the research and development phase for decades. Now they’re finally reaching the stage of technical maturity needed for commercial deployment, driving a surge in activity across the industry. DG Matrix’s emphasis is on creating flexible power conversion solutions, marketing its product as the world’s first “multi-port” solid-state transformer capable of managing and balancing electricity from multiple different sources at once.
“This Series A marks our transition from breakthrough technology to scaled infrastructure deployment,” Haroon Inam, DG Matrix’s CEO, said in a statement. “We are working with hyperscalers, energy companies, and industrial customers across North America and globally, with multiple gigawatt-class datacenters in the pipeline.” According to TechCrunch, data centers make up roughly 90% of DG Matrix’s current customer base, as its transformers can significantly reduce the space data centers require for power conversion.
Zero Homes, a digital platform and marketplace that helps homeowners manage the heat pump installation process, just announced a $16.8 million Series A round led by climate tech investor Prelude Ventures. The company’s free smartphone app lets customers create a “digital twin” of their home — a virtual model that mirrors the real-world version, built from photos, videos, and utility data. This allows homeowners to get quotes, purchase, and plan for their HVAC upgrade without the need for a traditional in-person inspection. The company says this will cut overall project costs by 20% on average.
Zero works with a network of vetted independent installers across the U.S., with active projects in California, Colorado, Massachusetts, Minnesota, and Illinois. As the startup plans for national expansion, it’s already gained traction with some local governments, partnering with Chicago on its Green Homes initiative and netting $745,000 from Colorado’s Office of Economic Development to grow its operations in Denver.
Climactic, an early-stage climate tech VC, launched a new hybrid fund called Material Scale, aimed at helping sustainable materials and apparel startups navigate the so-called “valley of death” — the gap between early-stage funding and the later-stage capital needed to commercialize. As Climactic’s cofounder Josh Fesler explained on LinkedIn, the fund is designed to cover the extra costs involved with sustainable production, bridging the gap between the market price of conventional materials and the higher price of sustainable materials.
Structured as a “hybrid debt-equity platform,” the fund allows Climactic’s investors to either take a traditional equity stake in materials startups or provide them with capital in the form of loans. TechCrunch reports that the fund’s initial investments will come from an $11 million special purpose vehicle, a separate entity created to fund a small set of initial investments that sits outside Material Scale’s main investing pool.
The fashion industry accounts for roughly 10% of global emissions. “These days there are many alt materials startups that have moved through science and structural risk, have venture funding, credible supply chains and most importantly can achieve market price and positive gross margins just with scale,” Fesler wrote in his LinkedIn post. “They just need the capital to grow into their rightful commercial place.”
