Economic and ecological evaluation of biogas plant configurations for flexible power generation

The transformation to an electricity system based on renewable sources is characterized by an increasing need for balancing power in order to compensate power supply from fluctuating sources, such as solar or wind. Biomass, more precisely energy from biogas, has the potential to generate electricity flexible on demand. Since electricity from biogas has not been used to balance fluctuations of intermittent renewable energies(RE) in the past, there is a need for new configurations that are able to meet the requirements of highly RE systems and to supply biogas according to the varying demand for balance power generation. In this regard, this presentation focuses on the economic and ecological evaluation of biogas plant configurations for flexible power generation.
