How Natural Hydrogen Forms and Accumulates Underground
The process begins with understanding how clean hydrogen is made. Water reacts with iron-rich rocks deep underground, releasing hydrogen gas in a process known as serpentinization. At temperatures between 302°F – 752°F the process emits hydrogen gas. Once formed, hydrogen travels through porous and fractured rocks. If it encounters a layer it cannot pass through, such as shale or salt, the gas becomes trapped and cannot escape past this barrier. Over time, it builds up and forms a potential reservoir for future extraction.
