Abstract: Recent developments in the energy sector require a combination of renewable carbon sources (e.g. biomass) and water electrolysis as a basis for electrical energy storage. While many approaches concentrate on the usage of hydrogen from electrolysis with CO2 for the generation of second generation fuels like synthetic natural gas, the presented paper introduces a combination with the Heatpipe Reformer biomass gasification process: This process produces a synthesis gas, which can be fully and directly converted to methane using additional hydrogen produced in an electrolyser. Furthermore, the applied nickel catalyst is able to convert higher hydrocarbons in the syngas, increasing methane yield and resulting in higher process efficiencies and no additional scrubbing for the adaptation of the CHO stoichiometry is necessary. The Heatpipe Reformer also allows pressurized gasification, which is beneficial for a subsequent methanation step.
