Story summary

Researchers found significant natural hydrogen reserves beneath the Earth's crust, potentially lasting 170,000 years.
Hydrogen generation occurs through water-rock reactions and radiolysis.
Geological sites for hydrogen include continental margin ophiolite complexes and alkaline granite terranes worldwide.
Extraction challenges involve high-purity hydrogen rarity and slow geological processes.
Natural hydrogen's low carbon footprint and production costs of $0.5 to $1.0 per kilogram enhance its viability.
