Houston-based project developer focused on energy transition has signed a new agreement to work on a synthetic fuels project in the Southwest United States.

GGS Energy and Australian company, Vast Renewables Limited, a renewable energy company specializing in concentrated solar thermal power systems, announced their agreement to work together on Project Bravo, Vast’s first deployment in the U.S. The company's CSP v3.0 technology will be deployed to create carbon-free heat and electricity for a co-located refinery that will generate green methanol and/or electrically powered sustainable aviation fuel, or e-SAF.

“CSP has the potential to unlock low-cost green fuel production in the U.S., and it can play a significant role in helping decarbonise shipping and aviation," Craig Wood, CEO of Vast, says in a news release. "We are delighted to have GGS Energy as a development partner to advance our plans in the U.S., which is a key market for Vast’s technology.”

Vast is currently building Solar Methanol 1, a CSP-powered green methanol reference plant that will be located in Australia at the Port Augusta Green Energy Hub. Project Bravo will build upon that plant here in the U.S. The location is still to be decided but will be in the Southwestern part of the country.

GGS Energy, which is founded in 2020 as a subsidiary of Glacier Global Partners that was formed in 2020, has infrastructure development experience across technologies, including utility scale CSP, coal-to-liquids projects, PV solar, wind, and more.

“GGS Energy is excited to partner with Vast and work to develop Project Bravo," Tommy Soriero from GGS Energy says in the release. "This collaboration marks a significant step toward a sustainable future, harnessing advanced technology to produce low-cost green fuels. We are eager to combine our expertise and resources to ensure the success and impact of future innovative projects starting with Project Bravo.”

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.”
