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.

Meta taps Houston geothermal co. to power data center growth with clean energy

big tech

A Houston company has signed a new agreement with Meta Platforms Inc. — Facebook's parent company — to power the tech giant's data center growth.

Houston-based Sage Geosystems agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta. The companies made the announcement this week at the United States Department Energy’s Catalyzing Next Generation Geothermal Development Workshop.

The deal is significant because it's the first next-generation geothermal project located to the east of the Rocky Mountains, the companies report in a news release.

“This announcement is the perfect example of how the public and private sector can work together to make the clean energy transition a reality,” Cindy Taff, CEO of Sage Geosystems, says in the release. “We are thrilled to be at the forefront of the next generation of geothermal technology and applaud the DOE for supporting the commercialization of innovation solutions.

"As energy demand continues to grow, the need for reliable, resilient and sustainable power is paramount and our partnership with Meta underscores the critical need for innovative and sustainable energy solutions like ours,” she continues.

The project's first phase will aim to be operating in 2027. The plans reflect how geothermal is being recognized as a growing carbon-free energy source in the country, and how Meta is committed to clean energy initiatives.

“The U.S. has seen unprecedented growth in demand for energy as our economy grows, the manufacturing sector booms thanks to the Biden-Harris Administration’s Investing in America agenda, and new industries like AI expand,” U.S. Energy Deputy Secretary David Turk says. “The Administration views this increased demand as a huge opportunity to add more clean, firm power to the grid and geothermal energy is a game-changer as we work to grow our clean power supply.”

Sage's technology — called Geopressured Geothermal System — works deep in the earth to develop energy storage and geothermal baseload power.

“Meta thanks the Department of Energy’s leadership on promoting and supporting the exploration of new energy sources like geothermal," Urvi Parekh, head of renewable energy at Meta, says. "That leadership supports Meta’s goal to enable the addition of reliable, affordable, and carbon-free power to the grid with this geothermal energy deal. We are excited to partner with such an innovative company like Sage Geosystems that is a proven leader in geothermal development on this project and beyond.”

Sage recently teamed up with a utility provider for an energy storage facility in the San Antonio metro area to build its three-megawatt EarthStore facility.

The company is also working on an exploratory geothermal project for the Army’s Fort Bliss post in Texas, which is the third U.S. Department of Defense geothermal initiative in the Lone Star State.

Houston company breaks ground on 'world's largest' geothermal project with next-generation tech

coming soon

Houston-based cleantech startup Fervo Energy has broken ground on what it's describing as the "world’s largest next-gen geothermal project."

Fervo says the a 400-milliwatt geothermal energy project in Cape Station, Utah, will start delivering carbon-free power to the grid in 2026, with full-scale production beginning in 2028.

The project, in southwest Utah, is about 240 miles southwest of Salt Lake City and about 240 miles northeast of Las Vegas. Cape Station is adjacent to the U.S. Department of Energy’s Frontier Observatory for Research in Geothermal Energy (FORGE) and near the Blundell geothermal power plant.

The company says Cape Station will generate about 6,600 construction jobs and 160 full-time jobs.

“Beaver County, Utah, is the perfect place to deploy our next-generation geothermal technology,” Tim Latimer, co-founder and CEO of Fervo, says in a news release. “The warmth and hospitality we have experienced from the communities of Milford and Beaver have allowed us to embark on a clean energy journey none of us could have imagined just a few years ago.”

In February, the U.S. Bureau of Land Management gave its blessing to the project, allowing Fervo to undertake exploration activities at the site.

“Geothermal innovations like those pioneered by Fervo will play a critical role in extending Utah’s energy leadership for generations to come,” says Utah Gov. Spencer Cox, who attended the groundbreaking ceremony.

Since being founded in 2017, Fervo has raised more than $180 million in funding. Its highest-profile investors are billionaires Jeff Bezos, Richard Branson and Bill Gates. They’re backing Fervo through Breakthrough Energy Ventures, whose managing director sits on Fervo’s board of directors.

Other investors include the Canada Pension Plan Investment Board (CPP Investments), DCVC, Devon Energy, Liberty Energy, Helmerich & Payne, Macquarie, the Grantham Foundation for the Protection of the Environment, Impact Science Ventures, and Prelude Ventures.

Fervo aims to generate more than one gigawatt of geothermal energy by 2030. On average, one gigawatt of power can provide electricity for 750,000 homes. Two coal-fired power plants can generate roughly the same amount of electricity.

Earlier this year, Fervo announced results of a test at Nevada’s Project Red site, which will supply power to Google data centers in the Las Vegas area. Fervo says the 30-day well test established Project Red as the “most productive enhanced geothermal system in history,” the company says. The test generated 3.5 megawatts of electricity.

In 2021, Fervo and Google signed the world’s first corporate agreement to produce geothermal power. Under the deal, Fervo will generate five megawatts of geothermal energy for Google through the Nevada project, which is set to go online later this year.

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.
