Houston-based clean energy company Syzygy Plasmonics has successfully tested all-electric CO2-to-fuel production technology at RTI International’s facility at North Carolina’s Research Triangle Park.

Syzygy says the technology can significantly decarbonize transportation by converting two potent greenhouse gases, carbon dioxide and methane, into low-carbon jet fuel, diesel, and gasoline.

Equinor Ventures and Sumitomo Corp. of Americas sponsored the pilot project.

“This project showcases our ability to fight climate change by converting harmful greenhouse gases into fuel,” Trevor Best, CEO of Syzygy, says in a news release.

“At scale,” he adds, “we’re talking about significantly reducing and potentially eliminating the carbon intensity of shipping, trucking, and aviation. This is a major step toward quickly and cost effectively cutting emissions from the heavy-duty transport sector.”

At commercial scale, a typical Syzygy plant will consume nearly 200,000 tons of CO2 per year, the equivalent of taking 45,000 cars off the road.

“The results of this demonstration are encouraging and represent an important milestone in our collaboration with Syzygy,” says Sameer Parvathikar, director of renewable energy and energy storage at RTI.

In addition to the CO2-to-fuel demonstration, Syzygy's Ammonia e-Cracking™ technology has completed over 2,000 hours of performance and optimization testing at its plant in Houston. Syzygy is finalizing a site and partners for a commercial CO2-to-fuel plant.

Syzygy is working to decarbonize the chemical industry, responsible for almost 20 percent of industrial CO2 emissions, by using light instead of combustion to drive chemical reactions.

Beginning in 2026, Shell will be able to apply 31 megawatts of 24/7 carbon-free geothermal power to its customers thanks to a new 15-year power purchase agreement with Houston next-gen geothermal development company Fervo Energy.

“This agreement demonstrates that Fervo is stepping up to meet the moment,” Dawn Owens, VP, Head of Development & Commercial Markets at Fervo, said in a news release.

Shell will become the first offtaker to receive electrons from Fervo's flagship geothermal development in Beaver County, Utah’s Phase I of Cape Station. Cape Station is currently one of the world’s largest enhanced geothermal systems (EGS) developments, and the station will begin to deliver electricity to the grid in 2026.

Cape Station will increase from 400 MW to 500 MW, which is considered by the company a major accomplishment due to recent breakthroughs in Fervo’s field development strategy and well design. Fervo is now able to generate more megawatts per well by optimizing well spacing using fiber optic sensing, increasing casing diameter and implementing staggered bench development. This can allow for a 100 MW capacity increase without the need for additional drilling, according to the company.

With the addition of the new Shell deal, all 500 MW of capacity from Fervo’s Cape Station are now fully contracted. The deal also includes existing agreements, like Fervo’s PPAs with Southern California Edison and an expanded deal with Clean Power Alliance that adds 18 MW of carbon-free geothermal energy to the company’s existing PPA with Fervo.

“As customers seek out 24/7 carbon-free energy, geothermal is clearly an essential part of the solution,” Owens said in the release.
