Method for demand-oriented generation of electrical power and / or demand-oriented provision of heat energy by means of at least one biogas plant

摘要

Proposed is a method for demand-oriented generation of electric power and demand-oriented provision of heat energy (9, 10) by means of at least one biogas plant (1), said biogas plant (1) the production of biogas from organic substrates (2) by biological treatment of the same after one known fermentation process with a first and a second fermentation stage (4, 5) with the exclusion of oxygen (anaerobic) and with the aid of biologically active microorganisms, wherein produced biogas in at least one cogeneration unit (6) to generate heat energy (9, 10) is streamed, and wherein the first fermentation stage (4) of the biogas plant (1) mesophilic and the second fermentation stage (5) are operated thermophilically with a specific temperature variation.
