Gold H2, a climate tech energy company, has completed the first field trial demonstrating subsurface bio-stimulated hydrogen production in California’s San Joaquin Basin.

The project uses Gold H2’s proprietary biotechnology to generate clean hydrogen directly from the subsurface, eliminating the need for new drilling or electrolysis facilities.

The technology could yield up to a quarter trillion kg of low-carbon hydrogen, providing clean power to Los Angeles for over 50 years.
