Abstract
Biomethanation is a biotechnological process for the production of methane from hydrogen and carbon dioxide, utilizing an archaeal group of microorganisms referred to as methanogens. Biomethanation can be performed by using pure and industrial emission waste gases in a continuous but also in discontinuous bioprocess mode. Volumetric methane productivity as high as 950 millimoles CH4 per litre and hour was achieved. Optimization of methane production regarding quality and quantity of methane is currently being examined.
