Small demonstration plant for the catalytic methanisation of the CO2 content in the biogas by hydrogen generated from steam in a SOEC (Solid Oxide Electrolyser Cells)-plant. Located at the Agricultural Research Centre of Aarhus University. The feasibility was investigated by means of engineering studies, energy system integration and economic scenario analyses and performance of a few critical experiments with SOEC cells. The outcome endeavoured to provide answers to the following questions: 1) What is the most cost effective upgrading route: Co electrolysis of the CO2 in the biogas with steam followed by methanation or steam electrolysis followed by methanation of CO2 in the biogas? 2) Can the steam reforming activity be controlled by sulphur without sacrificing to much electrochemical activity or lifetime of the cells?
