A new assessment has revealed that there is enough hydrogen stored underground to power the entire planet for 170,000 years. This startling figure, reported by Oil Price, reframes the potential role of natural hydrogen in the global energy transition. Unlike green hydrogen, which is produced using renewable energy and currently accounts for less than 1% of U.S. hydrogen output, geologic hydrogen could be extracted directly from subterranean reservoirs.
Green hydrogen has long struggled with high production costs and inefficiency, limiting its adoption despite its promise to decarbonize heavy industries like steelmaking and shipping. The fuel burns cleanly, leaving only water vapor, but scaling it has proven economically daunting. The discovery of vast natural hydrogen deposits could bypass these hurdles entirely.
Infrastructure implications are significant. While green hydrogen requires electrolyzers and substantial renewable power, geologic hydrogen may be accessed through conventional drilling techniques similar to natural gas extraction. This could accelerate the buildout of hydrogen pipelines, storage caverns, and distribution networks without the upstream energy penalty of electrolysis.
Geopolitically, the find reshuffles energy security calculations. Countries that sit atop these hydrogen reserves could gain strategic leverage similar to today's petrostates. The resource could reduce dependence on natural gas imports for industries that require high-temperature heat, and create new trade routes for hydrogen itself.
However, significant caveats remain. The 170,000-year estimate assumes current global energy consumption rates and full recovery of the resource — both questionable assumptions. Extraction technology is unproven at scale, and leakage risks during drilling and transport require careful study. Without further geophysical surveys and pilot projects, the true economic viability stays uncertain.
