Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

With an initial investment of $2 billion, AI chip manufacturer NVIDIA just acquired a 20 percent stake in The Woodlands-based Lancium, which develops large-scale campuses that combine AI data centers and onsite power supplies.

Lancium recently announced the investment but didn’t disclose the dollar amount. The Information news website reported NVIDIA’s investment totaled $2 billion, with the possibility of an additional $1 billion if Lancium achieves certain milestones.

Dealroom.co calls NVIDIA’s investment a “form of supply-chain insurance.”

NVIDIA “is gaining exposure to the scarce physical assets that determine whether its chips can be deployed,” Dealroom.co says. “The move makes Nvidia look less like a pure chip company and more like an allocator of infrastructure capacity.”

Investment precedes possible IPO in 2027

Thanks to NVIDIA’s cash infusion, Lancium and its portfolio of land and power connections carry an enterprise value of about $10 billion, according to The Information.

The investment should enable Lancium to expand as it explores a potential IPO next year, The Information reported.

Neither Lancium nor NVIDIA is responding to requests for comment about the deal.

Lancium’s marquee project is a 1,000-acre data center and power generation campus in West Texas for the $500 billion Stargate initiative. Stargate, a joint venture comprising MGX, OpenAI, Oracle and SoftBank, is building data centers equipped to handle AI-level workloads.

“Epicenter of energy and AI infrastructure”

Founded in 2017, Lancium has 4 gigawatts of leased capacity and a more than 15-gigawatt development pipeline. In 2024, Blackstone Energy Transition Partners invested about $500 million in Lancium, giving Blackstone a roughly 50 percent stake.

“This partnership with NVIDIA is a strong testament to Lancium’s position at the epicenter of energy and AI infrastructure … . We look forward to continuing to partner with these leading companies to help power the next generation of AI innovation,” Bilal Khan, senior managing director at Blackstone, said in a release.

Through the NVIDIA partnership, Lancium’s data center and power generation campuses will use the tech company’s “AI factory” platform, including software, computing, and networking capabilities. This will give NVIDIA customers and partners access to power capacity that supports heavy AI workloads.

“We have spent years assembling the power, the land, and the infrastructure expertise needed to deliver AI data center capacity at a scale the world has never seen,” Michael McNamara, co-founder and CEO of Lancium, said in the release.

“Partnering with NVIDIA — the definitive technology platform for AI computing — ensures that every campus in our portfolio will be deployed with the industry’s most advanced technology and that NVIDIA’s customers will have access to the capacity they need to compete and lead in the AI era.”
