Scientists think a hidden source of clean energy could power Earth for 170,000 years — and they've figured out the 'recipe' to find it

Recent research indicates extensive hydrogen reservoirs exist globally, including in over 30 U.S. states. Earth's crust has generated enough hydrogen in the past billion years to meet current energy needs for 170,000 years. Scientists have identified geological conditions for hydrogen accumulation, including source rocks, reservoir rocks, and natural seals. Promising exploration areas include ophiolite complexes, igneous provinces, and Archaean greenstone belts. This discovery could expedite the transition to clean energy due to natural hydrogen's smaller carbon footprint compared to hydrogen from hydrocarbons.
