Hydrogenotrophic methanogenesis

Hydrogenotrophic methanogenesis is a biological process where certain microorganisms, called methanogens, produce methane by using hydrogen gas and carbon dioxide as their main ingredients. These microbes consume hydrogen and carbon dioxide, converting them into methane—a type of natural gas—and water. This process occurs naturally in environments like wetlands, lakes, or the guts of some animals, as well as in engineered systems like biogas reactors. It plays a crucial role in the global carbon cycle and is a key step in breaking down organic materials anaerobically (without oxygen).
