Funding Friday: Stretching the Limits of Climate Tech

On Breakthrough Energy Ventures’ quantum computing investment, plus more of the week’s biggest money moves.

It’s been a busy week for funding, with several of the most high-profile deals featured in our daily AM newsletter, including Slate Auto’s $650 million fundraise for its stripped-down electric truck and Rivian’s partnership with Redwood Materials to repurpose the electric automaker’s battery packs for grid-scale storage.

These are clearly companies with direct decarbonization implications, but one of the week’s other biggest announcements raises the question: Is this really climate tech? That would be quantum computing startup Sygaldry, which recently nabbed $139 million in a round led by Breakthrough Energy Ventures to build quantum AI infrastructure. Huh.

Elsewhere in the ecosystem, the climate connection is a little more straightforward, with new funding for advanced surface materials designed to improve insulation and fire-protection, capital for microgrids that can integrate a diverse mix of generation and storage assets, and federal support for next-generation geothermal tech.

Sygaldry Snags $139 Million to Build Quantum-Powered AI

Quantum computing offers a futuristic paradigm for high-powered information processing and problem solving. By leveraging the principles of quantum mechanics, these systems operate in fundamentally different ways than even today’s most advanced supercomputers, encoding information not as ones and zeros, but as quantum units called “qubits.” Naturally, there is significant interest in applying this novel tech — which today remains error-prone and not ready for prime time — to artificial intelligence, with the aim of exponentially accelerating certain training and inference workloads.

Perhaps less intuitively, however, these next-generation computers are now viewed, at least by one prominent venture capital firm, as a key climate technology.

This week, quantum computing startup Sygaldry raised a $139 million Series A round led by Bill Gates’ climate tech VC firm Breakthrough Energy Ventures to build “quantum-acclerated AI servers” for data centers, which could reduce the cost and power required to train and operate large models. “The AI industry is advancing faster than ever and needs a breakthrough in performance per watt,” Carmichael Roberts, Breakthrough Energy Ventures’ chief investment officer said in the press release. “Sygaldry’s vision for bringing quantum directly to the AI data center has the potential to deliver exactly that, bending the cost and energy curve at the moment it matters most."

Certainly Sygaldry’s ultra-high-powered computers could help lower the energy intensity of AI workloads, but that is no guarantee that it will reduce AI and data center emissions overall. As was widely discussed when the Chinese AI firm DeepSeek released its cheaper, more energy-efficient model early last year, efficiency gains could reduce emissions in the sector at large, but they are perhaps just as likely — or some argue even more likely — to drive greater proliferation of AI across a wide array of industries. This unfettered growth could offset efficiency gains entirely, leading to a net increase in AI power demand.

NanoTech Materials Raises $29 Million for Heat- and Fire-Resistant Coatings

Buildings account for nearly 37% of domestic energy consumption, with heating and cooling representing the largest share of that load. But while energy efficiency strategies typically focus on upgrading insulation or adjusting the thermostat, there’s another approach — essentially painting the roof with sunlight-reflecting material — that has the potential to reduce AC demand and thus cut a building’s cooling-related energy use by up to 50%.

Just such a “paint” is one of the unique ceramic coatings developed by NanoTech Materials, which this week raised a $29.4 million Series A to scale its infrastructure materials business. Beyond roofing, the company also offers a fire-protective coating for wooden infrastructure such as utility poles, fences, highway retaining walls, and other transportation assets, as well as an insulative coating for high-heat industrial equipment such as pipes and storage tanks designed to slow heat loss and prevent burn risk.

“Today’s built environment demands materials that don’t just meet code, but can also outperform the extreme conditions we’re now facing,” said D. Kent Lance, a partner at HPI Real Estate Services & Investments, which led the Series A. Nanotech Materials currently operates a manufacturing facility in Texas and plans to use this new capital to further expand its operations as it conducts market research for its various product lines.

Critical Loop Lands $26 Million to Build Microgrids For Faster Grid Interconnection

Interconnection delays aren’t just a data center problem. Industrial developers working on everything from real estate and electric vehicle charging to manufacturing and aviation are also struggling to get timely and reliable access to power when building or expanding their operations. Enter Critical Loop. This modular microgrid company is building battery energy storage systems that can integrate batteries of varying sizes and specifications with a variety of power sources, including onsite solar, diesel generators, and grid power.

This week, the startup announced a $26 million Series A round, bringing total funding to $49 million across all equity and debt financing. Critical Loop’s approach combines a software platform with proprietary hardware — what it calls a “combiner” — which reduces the need for the many custom components typically required to connect a diverse mix of batteries and generation sources. “There’s a lot of power problems that are not getting solved because of limitations on an understanding of how to integrate different systems at a site,” Critical Loop’s CEO Balachandar Ramamurthy, told me last month.

The company’s initial product is a modular single-megawatt battery system that can be transported in shipping containers for rapid deployment in capacity-constrained locations. To date, Critical Loop has deployed about 50 megawatt-hours of microgrid assets, with plans to scale to over 100 megawatt-hours by year’s end.

DOE Announces $14 Million for Enhanced Geothermal Project in Pennsylvania

It’s been another exciting week for one of the few bipartisan bright spots in clean energy — geothermal development. My colleague Alexander C. Kaufman reported in this morning’s AM newsletter that the AI-native geothermal company Zanskar secured $40 million through one of the first development capital facilities for early-stage geothermal development, and now the technology has secured fresh capital from the fickle U.S. Department of Energy. Today, the DOE announced a $14 million grant to support an enhanced geothermal demonstration project in Pennsylvania that will convert an old shale gas well into a geothermal pilot plant.

Conventional geothermal systems depend on a highly specific set of subsurface conditions to be commercially viable, which includes naturally occurring underground reservoirs where fluid flows among hot rocks. By contrast, developers of enhanced geothermal systems effectively engineer their own reservoirs, hydraulically fracturing rock formations and then circulating water through those man-made fractures to extract heat that’s then used to generate electricity. A number of well-funded startups are advancing this approach using drilling techniques adapted from the oil and gas industry, such as Fervo Energy — which has an agreement with Google to supply electricity for its data centers — and Sage Geosystems, which has a similar tie-up with Meta.

“As the first enhanced geothermal systems demonstration site located in the eastern United States, this project offers an important opportunity to assess the ability of such systems to deliver reliable, affordable geothermal electricity to Americans nationwide,” Kyle Haustveit, the Assistant Secretary of the Hydrocarbons and Geothermal Energy Office, said in the DOE release. If successful, the Energy Department says the project could provide a replicable model for scaling the deployment of enhanced geothermal systems across a broader range of geographies.

Bonus: XPRIZE and Amazon Launch Critical Minerals Circularity Challenge

This week, the nonprofit XPRIZE organization announced that it’s partnering with Amazon to launch a new global competition focused on critical mineral circularity — redesigning how minerals such as lithium, cobalt, and nickel are recovered, processed, and reused. Demand for these minerals is projected to quadruple by 2040, but their supply chains remain largely concentrated in China, especially across refining, processing, and battery manufacturing.

The competition aims to catalyze breakthroughs in mineral recovery and recycling, materials solutions, and lower-impact extraction methods. It’s not yet open to submissions as organizers are still seeking philanthropic and corporate funding before entrepreneurs, startups, and research teams can submit their ideas for consideration. XPRIZE has been running challenges for three decades now, with past competitions revolving around carbon removal, adult literacy, and lunar exploration.

People Who Hate Renewables Hate Data Centers, Too

And more thoughts on the week’s most notable fights around project development.

The United States.

1. Pinal County, Arizona – If you can’t build a solar or a wind farm somewhere, it’s really hard to get a data center built there too.

  • That’s the lesson readers should take away from the situation in Pinal County, where historically speaking at least 5 solar projects have been withdrawn over the years after facing local opposition, according to Heatmap Pro data. You should expect some data centers to potentially wind up in the same graveyard.
  • On Wednesday, the Pinal County Board of Supervisors rejected the La Osa Energy Center, a large proposed data center and gas-fired power complex. The board in this deep red rural desert community is rock-ribbed Republican. Only one supervisor on the board dissented, citing private property rights concerns.
  • The county currently has a restrictive ordinance against data center development unless they are in industrial areas, but has not yet approved a project since the ordinance was crafted, making this now a de facto no-go zone for developers. This went against the requests of the county zoning board, which recommended making the project site as industrial. If that pattern sounds familiar to you, that’s because you recognize it from the many cases we’ve seen in solar and wind development where political officials similarly override zoning staff.

2. St. Joseph County, Indiana – Thousands of miles away from Arizona, a similar division is dominating the fight over whether to enact a 2-year moratorium on data centers in the county home of South Bend.

This week’s conversation is with Nevada attorney general Aaron Ford, the Democratic candidate for governor in the state. His campaign reached out recently asking if I wanted to chat about what he’d want to do on data center and energy policy, which is essentially catnip for a reporter like me. So we hopped on the phone and chatted about his approach to regulation as he seeks to oust the sitting GOP governor Joe Lombardo.

The following conversation was lightly edited and abridged for clarity.

The most important states to watch for the future of renewable energy policy sit at the nexus of the data center backlash.

Over the last week, I’ve pored over what I believe to be the top five most important spaces to watch for all things utility-scale solar, battery storage and transmission development: Texas, California, Arizona, Alabama and Wisconsin. I selected these five states because they either have some of the largest generation capacity (Texas, California, Arizona) or crucial statewide elections that could decide not only the future of renewable energy in the state but elsewhere across the country (Alabama, Wisconsin).
