Overview

• Earth's crust contains vast natural hydrogen reserves, potentially sufficient to meet global energy demands for over 170,000 years.
• A study published in *Nature Reviews Earth & Environment* provides a first-principles 'exploration recipe' to identify, trap, and preserve hydrogen accumulations underground.
• Key geological conditions include reactive rock types, water interaction, porous storage rocks, and impermeable seals to trap the gas.
• Challenges such as hydrogen consumption by underground microbes and preservation of viable reservoirs remain under active investigation.
• The formation of Snowfox Discovery Ltd. signals growing commercial interest, with backing from major investors like Bill Gates and BP to scale up exploration efforts.
