Sage Geosystems, a Houston-based developer of geothermal power systems, has chosen a site in Nevada for its commercial-scale Project Vector facility.

The company’s two-well enhanced geothermal system (EGS) will deliver around-the-clock geothermal heat to Ormat Technologies’ Blue Mountain geothermal power plant in Winnemucca, Nevada.

The startup expects to begin drilling the first well later this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

In the Nevada system, fluid will circulate through an engineered subsurface reservoir, absorb heat from the surrounding rock and return heat to the surface. The heat will be delivered to the Blue Mountain plant for conversion into electricity.

Project Vector builds on the performance of Sage’s SMECI facility in South Texas. That facility’s results, combined with Sage’s digital twin platform, will be used to shape to the design and development of Project Vector.

Project Vector supports Sage’s growing commercial pipeline, including a 150-megawatt geothermal power agreement with Meta Platforms, the parent company of Facebook and Instagram.

“Blue Mountain is an ideal location for Sage to take the next step in continuing to commercialize our proprietary EGS approach,” Jason Peart, chief operating officer at Sage, said in a release. “By delivering geothermal heat into an existing power plant, Project Vector can demonstrate the model for bringing firm, 24/7 geothermal power to market at scale.”

Project Vector extends Sage’s relationship with Ormat.

In August 2025, Sage and Ormat agreed to accelerate commercialization of Sage’s geothermal technology at an Ormat power plant. This January, Ormat co-led Sage’s $97 million Series B funding round.

Sage, founded in 2020, has raised about $159 million across three funding rounds.

As the startup ramps up its ESG platform, Sage is targeting data centers as customers, among other large-scale users of electricity.

“The energy needs are huge, and they need it now,” CEO Cindy Taff said on Data Center Frontiers’ podcast. “They can’t depend on the grid anymore.”

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

Baker Hughes teams up with Google and XGS on energy tech

project partners

Houston-based energy technology company Baker Hughes recently forged two significant partnerships—one with tech titan Google and another with geothermal power startup XGS Energy.

Under the Google Cloud partnership, announced at CERAWeek 2026, Baker Hughes technology will be paired with Google Cloud AI and data analytics to improve the performance of AI data centers’ power systems and energy-transfer machinery. Furthermore, the two companies will explore opportunities for data centers to extract greater value from underused industrial and operational data.

“Infrastructure that powers the growing demand for AI and cloud computing is becoming one of the most critical drivers of global electricity needs,” Lorenzo Simonelli, chairman and CEO of Baker Hughes, said in the announcement.

“Through this partnership with Google Cloud, we are bringing together world-class power technologies and digital capabilities to help data center operators improve efficiency, enhance reliability, and accelerate progress toward lower-carbon operations,” he added.

Through the XGS partnership, Baker Hughes will provide engineering services for XGS’ 150-megawatt geothermal project in New Mexico. The project will supply energy to the Public Service Co. of New Mexico grid in support of New Mexico data centers operated by Meta Platforms, the parent company of Facebook and Instagram.

“With this single project for Meta in New Mexico, XGS will increase the state’s operating geothermal capacity by tenfold,” says Ghazal Izadi, chief operating officer at XGS.

“Geothermal energy plays a vital role in delivering reliable, cleaner power at scale,” added Maria Claudia Borras, chief growth and experience officer and interim executive vice president of industrial and energy technology at Baker Hughes. “By collaborating with XGS at this early stage, we are applying our ground‑to‑grid capabilities to reduce technical risk, accelerate reservoir validation, and engineer an integrated solution to deliver … power efficiently and reliably.”

California-headquartered XGS, which has a major presence in Houston, is known for its proprietary solid-state geothermal system that uses thermally conductive materials to deliver affordable energy wherever there is hot rock.

Fervo taps into its hottest-ever geothermal reservoir

heat record

Things are heating up at Houston-based geothermal power company Fervo Energy.

Fervo recently drilled its hottest well so far at a new geothermal site in western Utah. Fewer than 11 days of drilling more than 11,000 feet deep at Project Blanford showed temperatures above 555 degrees Fahrenheit, which exceeds requirements for commercial viability. Fervo used proprietary AI-driven analytics for the test.

Hotter geothermal reservoirs produce more energy and improve what’s known as energy conversion efficiency, which is the ratio of useful energy output to total energy input.

“Fervo’s exploration strategy has always been underpinned by the seamless integration of cutting-edge data acquisition and advanced analytics,” Jack Norbeck, Fervo’s co-founder and chief technology officer, said in a news release. “This latest ultra-high temperature discovery highlights our team’s ability to detect and develop EGS sweet spots using AI-enhanced geophysical techniques.”

Fervo says an independent review confirms the site’s multigigawatt potential.

The company has increasingly tapped into hotter and hotter geothermal reservoirs, going from 365 degrees at Project Red to 400 degrees at Cape Station and now more than 555 degrees at Blanford.

The new site expands Fervo’s geologic footprint. The Blanford reservoir consists of sedimentary formations such as sandstones, claystones and carbonates, which can be drilled more easily and cost-effectively than more commonly targeted granite formations.

Fervo ranks among the top-funded startups in the Houston area. Since its founding in 2017, the company has raised about $1.5 billion. In January, Fervo filed for an IPO that would value the company at $2 billion to $3 billion, according to Axios Pro.

Fervo Energy spotlighted by Bill Gates as geothermal’s global growth driver

geothermal predictions

In a new blog post spotlighting Houston-based geothermal power startup Fervo Energy, billionaire Bill Gates — a Fervo investor — predicts geothermal will eventually supply up to 20 percent of the world’s electricity, up from his previous estimate of as much as 5 percent.

Today, geothermal accounts for less than 1 percent of electricity generated around the world, according to the International Energy Agency. The agency forecasts geothermal will represent up to 15 percent of global power by 2050.

“Geothermal power will have a big role to play in our clean energy future, and it’s exciting to see companies like Fervo push the technology to new depths,” Gates wrote.

Gates’ more than $1 billion Breakthrough Energy Ventures fund has contributed to the $982 million pool of money that Fervo has raised since its founding in 2017. Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. Its valuation has been estimated at $1.4 billion.

The Microsoft billionaire published the blog post on his Gates Notes website after touring the site of Fervo’s Cape Station geothermal project, which is under construction in Utah. Fervo says Cape Station will be the world’s largest geothermal plant, capable of someday producing up to 2 gigawatts of power.

Earlier this year, Fervo raised $206 million to put toward the development of Cape Station. Of that amount, $100 million came from Breakthrough Energy Catalyst, a green tech investment program backed by Gates, according to Inc.com.

The first phase of Cape Station is scheduled to be completed in 2026, with first-year power generation pegged at 100 megawatts. An additional 500 megawatts of power-producing capacity is slated to go online in 2028.

“Geothermal is one of the most promising ways to deliver clean energy that’s reliable and affordable,” Gates wrote.

In the blog post, Gates praised the simplicity of geothermal energy.

“The interior of the Earth is incredibly hot, and the deeper you go, the hotter the ground becomes,” he explained. “If you pump fluid deep enough to be warmed by this heat and then pump it back to the surface, you can turn the hot liquid into steam and use it to spin turbines and generate electricity — just like many other types of power plants.”

Gates noted that horizontal drilling is one of Fervo’s biggest innovations. The company extends its wells horizontally by as much as 5,000 feet at the deepest point. It couples horizontal drilling with hydraulic fracturing, or fracking, to extract geothermal energy from rock formations.

Most wells at Cape Station are 8,000 to 9,000 feet deep, and the deepest one is 15,000 feet below the surface, Gates pointed out.

Gates also emphasized the water-conserving, closed-system setup at Cape Station.

“Geothermal energy is one of the more climate-friendly sources of power, but one of its downsides is how much water it uses. … Fervo’s technology captures all the water that would’ve been lost and recirculates it underground to keep the system running,” he wrote.

Fervo Energy lands $200 million in capital for new geothermal project

fresh funding

Houston-based Fervo Energy, a producer of geothermal power, has secured $205.6 million in capital to help finance its geothermal project in southern Utah.

The money will go toward the first and second phases of Cape Station, a geothermal energy plant being developed in Beaver County, Utah. Beaver County is roughly an equal distance between Salt Lake City and Las Vegas.

The $205.6 million in capital came from three sources:

  • $100 million in equity from Breakthrough Energy Catalyst, a Kirkland, Washington-based platform that invests in emissions-reducing projects.
  • $60 million addition to Fervo’s existing loan from Mercuria, a Swiss energy and commodities trader. The revolving loan now totals $100 million.
  • $45.6 million in additional bridge debt financing from XRL-ALC, an affiliate of Irvington, New York-based X-Caliber Rural Capital. X-Caliber is a USDA-approved lender. The initial bridge loan was $100 million.

The first phase of Cape Station will supply 100 megawatts of carbon-free electricity to the power grid starting next year. Another 400 megawatts of capacity is supposed to go online by 2028. Fervo has permission to expand Cape Station’s capacity to as much as 2 gigawatts. On an annual basis, 2 gigawatts can supply enough electricity to power about 1.4 million homes.

“These investments demonstrate what we’ve known all along: Fervo’s combination of technical excellence, commercial readiness, and market opportunity makes us a natural partner for serious energy capital. The confidence our investors have in Fervo and in the Cape asset affirms that next-generation geothermal is ready to play a defining role in America’s energy future,” David Ulrey, Fervo’s CFO, said in a news release.

TotalEnergies expands solar joint venture with $1.2B portfolio in Texas, Ohio

solar expansion

TotalEnergies, a French company whose U.S. headquarters is in Houston, announced this month that it is expanding its renewable energy joint venture with New York-based investment firm KKR by adding 700 megawatts of utility-scale solar projects.

The deal will add three utility-scale solar assets in Texas and Ohio, which are expected to reach commercial operation by Q1 2027, according to a news release from the company. The portfolio is valued at $1.2 billion.

The 50/50 joint venture between TotalEnergies and KKR currently holds 1.4 gigawatts of renewable energy and will grow to 2.1 gigawatts.

The new deal is expected to close this year. Once completed, TotalEnergies will operate the assets. The electricity generated from the solar projects will be sold to third parties, the company reports.

The companies originally formed the joint venture about a year ago when TotalEnergies sold KKR a 50 percent stake in a North American solar portfolio valued at $1.25 billion. The deal originally included six utility-scale solar assets, primarily located in the U.S.

“TotalEnergies is a renewable energy industry leader globally, and we are thrilled to establish this joint venture with the TotalEnergies team to support their renewables business," Cecilio Velasco, managing director KKR, said in a release last year. “We have long been investors in renewables through our infrastructure platform, having committed more than $23 billion to date in energy transition investments. TotalEnergies’ North American solar portfolio is a great fit for us, representing high-quality renewable energy assets with long term contracts.”

TotalEnergies reports that by June 2026 it held more than 37 gigawatts of gross renewable power generation capacity. It aims to achieve over 100 terawatt-hours of net electricity production by 2030.

The company signed a major power purchase agreement with Google earlier this year. Through the deal, TotalEnergies will supply the tech giant with 1 gigawatt of solar power for its data centers in Texas over a 15-year span.

However, the company also recently redirected nearly $1 billion in capital away from wind energy projects and "decided to renounce offshore wind development in the United States." Read more here.

Houston researchers develop compact carbon capture tech for data centers

AI emissions

Two scientists from the University of Houston have been experimenting with new carbon capture systems that fit inside a standard shipping container, which have the potential to make eliminating carbon output from industrial sites much easier.

The capture of industrial carbon is an important complement to the fight against climate change, as well as winning tax credits for businesses that use carbon capture technology.

The problem is that such systems are often measured in acres, making them expensive to build and extremely power-hungry to actually use. UH Engineering Professor Mim Rahimi and former UH Ph.D. student Ahmad Hassan (now a postdoctoral associate at Harvard) have managed to fit their new system, the Small Modular Electrochemical Container (SMECs), inside a standard 40-foot shipping crate, making them compact and modular enough to be installed almost anywhere for operations of all sizes. Their research was recently published in the journal Environmental Science & Technology.

“With a conventional system, you’re building a 130-foot-tall structure designed for a specific power plant. With our technology, we can adjust the capacity by simply turning containers on or off,” Rahimi said in a news release. “That flexibility is particularly important for data centers, where electricity can come from a combination of natural gas and renewable sources.”

Rahimi and Hassan used simulated gas models to show that under optimal conditions, the SMEC used electrochemically mediated amine regeneration (EMAR) cells developed in Rahimi’s lab to capture 90 percent of carbon under optimal conditions through 300 cycles over 50 hours.

Encouraged, the team then modeled a 360-megawatt natural gas power plant associated with OpenAI’s Stargate AI data center project in Abilene, Texas. In addition to the savings on infrastructure costs, 20 of the researchers’ shipping container systems were able to capture 98 percent of carbon from Stargate’s 875-acre campus based on the model.

The looming energy costs and subsequent carbon emissions from data centers are a real concern. Estimates from the U.S. Department of Energy hypothesize that 12 percent of America’s energy needs could be gobbled up by the centers as soon as 2028. That is a massive new source of carbon. The flexibility of the SMEC means they can be deployed wherever the centers spring up.

“We’re taking a technology that traditionally requires enormous infrastructure and finding a way to fit it inside a shipping container,” Rahimi added in the release. “That opens up entirely new possibilities for how and where carbon capture systems can be used.”

In the future, the researchers say they plan to look at ways to adapt the technology to capture carbon dioxide directly from the atmosphere.

Hertha Metals breaks ground on $100M high-purity iron factory in Conroe

coming soon

Shortly after announcing a $133.65 Series A funding round, Conroe-based Hertha Metals broke ground Oct. 8 on a $100 million factory that will produce steel-grade and magnet-grade high-purity iron.

Hertha’s Chalyx plant, located in Conroe, will manufacture a total of about 10,000 metric tons per year of magnet-grade and steel-grade high-purity iron. The factory will use Hertha’s single-step process to generate high-purity iron for rare-earth-magnet and steel manufacturers in the U.S.

Hertha says Chalyx will be the first U.S. commercial plant for production of magnet-grade high-purity iron.

Chalyx is being built next to Hertha’s headquarters and its Pi100 pilot plant, which will remain in operation. Chalyx and Pi100 will form the first modern-day iron and steel “innovation complex” in the U.S., the company says.

“I founded Hertha Metals because I believed we could significantly improve how the world makes iron and steel from ore, and that an industry so fundamental to our future still had enormous room for invention,” Laureen Meroueh, founder and CEO of Hertha, said in a press release.

The 4-year-old startup says the Chalyx complex will lay the foundation for its first 500,000-ton-per-year steel mill.

Chalyx’s first priority is making high-purity iron for U.S. manufacturers of rare-earth magnets, Hertha says. These magnets are critical components for electric vehicles, data centers, wind turbines and defense systems.

China produces an estimated 94 percent of high-purity iron for rare-earth magnets, according to Hertha.

Aside from iron for rare-earth magnets, Chalyx will make iron and steel for pilot projects in the steel industry.

The plant is expected to come online in late 2027, with production of magnet-grade high-purity iron starting in early 2028.

Today, Hertha employs 32 people, the company says. Once it’s fully operating, the Chalyx plant will employ about 50 people.

Just ahead of the groundbreaking, Hertha announced the $133.65 million Series A round, co-led by Khosla Ventures and Doerr Capital. The round included a $65 million equity investment from the Pentagon.

“Iron and steel have shaped human progress for thousands of years. And I believe there is still an enormous amount left to invent,” Meroueh said at the groundbreaking ceremony.
