Energy transition and biogas

Just like hydrogen, solar and wind energy and heat pumps, biogas can play a role in the transition to a more sustainable energy supply. This can be done in various ways: as ‘pure’ biogas, but mainly as reprocessed green gas in the transport world and by feeding it into our current natural gas network. 

Biogas can be used as a fuel in the transport sector. For example, cars and buses can run on bio-CNG. That is Compressed Natural Gas (CNG) based on biogas. It is created by removing carbon dioxide, sulfur and moisture from the biogas and then compressing the remaining methane under high pressure. Bio-LNG, biogas liquefied through cooling, is ideally suited to drive trucks and ships. As a fuel for heavy road transport, biogas is regarded as an interim solution. In the long term trucks will have to drive electrically or be powered with green hydrogen.

Although it is technically possible, biogas is less suitable for household use. Nevertheless, biogas can be used as an energy source for heating, for example in factories and swimming pools or in the agricultural sector, thus creating an energy cycle. Biogas can also be used to generate electricity in a cogeneration plant (CHP).
