HOUSTON, TEXAS (Ofelia Paredes, Energy Analytics Institute, 24.Jun.2025, Words: 203) — Climate tech energy company Gold H2 completed the world’s first field trial demonstrating subsurface bio-stimulated hydrogen production.
ChampionX LLC served as the oilfield services provider, playing a critical role in the efficient deployment and field validation of this breakthrough process.
Conducted in a legacy oilfield in California’s San Joaquin basin, the trial represents a landmark advancement in the energy transition, one that leverages microbiology and existing infrastructure to produce clean hydrogen directly from the subsurface, Gold H2 announced on 24 Jun. 2025 in an official statement.
The project marks the first-of-a-kind application of Gold H2’s proprietary biotechnology, which harnesses microbiology, depleted oil reservoirs, and existing infrastructure to generate hydrogen in situ, eliminating the need for new drilling, electrolysis, or energy-intensive surface facilities.
Gold H2’s subsurface hydrogen biotechnology represents a transformative shift in clean energy development. California’s depleted oilfields alone could yield up to a quarter trillion kilograms of low-carbon hydrogen, enough to provide clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent. The global potential is far greater, according to Gold H2.
