Abstract:
The aim of this paper is to give a brief overview of the studies conducted during the emph{Large Scale Bio Energy Lab} concerning biogas upgrading. An integrated process scheme was developed, combining anaerobic digestion as an simple and robust technology for waste treatment with the hydrogen technology for renewable energy storage. A low-strength waste water from a local dairy was used to produce biogas from a two-phase digestion system was used containing a continuous stirred tank reactor and an anaerobic baffled reactor. The anaerobic digestion was followed by a dynamic process possible to run in two states: (i)~the derived biogas can be utilized via CHP generation or, (ii)~ mixed with hydrogen, so it can be converted into synthetic natural gas by a chemical process, called Sabatier process. Feasibility studies, simulation and experiments proofed this dynamic biogas upgrading process as an excellent tool for local integration of biomass and waste streams from industry together with renewable hydrogen into existing energy systems.
