Biogas is a renewable energy source that is produced from the fermentation of biomass such as sugar beet, straw or liquid manure. Biogas can be converted directly into electricity and heat or refined into biomethane and fed into the natural gas grid. The advantage of biomethane is that it is climate-neutral and has the same properties as fossil…

„Currently, our renewable electricity production is limited during periods of low demand. Instead of shutting off wind and solar plants, we can convert this excess energy into gases that can be stored and used flexibly. By this, we can increase the share of renewable energies in our overall energy supply.”

Tobias Eckhof, Project manager ‚Hydrogen‘…
