Biogas

Biogas is a gaseous mixture which arises as a result of biological enzymatic processes. Biogas can be produced from wet biomass such as manure, plant material, or food waste. The main components of biogas are methane and carbon dioxide.

Biogas upgrading

Biogas can be upgraded to natural gas quality by removing the impurities and majority of carbon dioxide. It is then called green gas. The upgrading of biogas is mostly executed on a large scale at central biogas upgrading plants. HyGear is developing small-scale biogas upgrading systems, the Bio.PURE. The Bio.PURE overcomes transportation of biogas or biomass by converting the waste streams into value on-site. This increases the energy efficiency and reduces emissions.

Applications

The Bio.PURE can be installed at digesters and gasifiers. The generated green gas can be used on-site or fed into the gas grid or can be converted into hydrogen.
