Technical Modifications and Concepts for a Controllable Electricity Production via Biogas Plants in Germany

With the expansion of renewable but fluctuating power generation from wind and solar energy, the demand placed on the security and reliability of electricity supply is increasing. To ensure grid stability in the future, controllable power production via biogas plants has a great technical and economic potential. In this context, the CENTRE OF EXCELLENCE FOR RENEWABLE ENERGY RESEARCH at Ingolstadt University of Applied Sciences and the biogas plant manufacturer UTS Biogastechnik GmbH, Hallbergmoos, Germany, are working on the research project “BioStrom – Controllable Electricity Production via Biogas Plants”, funded by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. This paper describes first results regarding technical modifications for acontrollable electricity production via biogas plants. Furthermore, the operational mode of CHP­Units in accordance with the demand of the electricity grid and achievable additional revenues are shown by taking the limited gas storage volume into account.
