Engineered Geologic Hydrogen
Engineered geologic hydrogen — which accelerates the same subsurface rock chemistry that produces hydrogen naturally — is an early-stage and high-risk bet on a potentially transformative approach to low-cost, low-emission hydrogen production. The field is pre-commercial with significant technical and regulatory hurdles remaining, though growing government funding and startup activity suggest it could become a serious hydrogen supply pathway over the next decade for those willing to take on the risk and/or tired of waiting for on the "what if" deposits promised from the natural geologic space.
