Sabatier process

The Sabatier process is a chemical reaction that combines carbon dioxide (CO₂) with hydrogen (H₂) to produce methane (CH₄) and water. This process uses a catalyst, usually nickel, to facilitate the reaction. It is useful for creating fuel on sites like spacecraft or submarines, where resources are limited. By recycling waste CO₂ and hydrogen, the process helps generate usable energy and water, making it an efficient way to sustain life and operations in isolated or contained environments.
