Technical and economical feasibility of a renewable electricity storage loop on methane by the way of a reversible SOEC – DEMETER
The object of the Demeter Project is to do the technical and economical evaluation of a stocking and destocking unit of electricity coming from renewable energies on methane by the way of a reversible Solid Oxide Electrolyser. In the Demeter concept the unit is upstream bonded with an electrical network and downstream with a gas network. In stocking phase the electricity produced in excess by the renewable energy sources is used to electrolyse a mixture of water vapour and CO2 at high temperature in a SOEC. The gas mixture (H2+CO) produced is sent to a methane former. The methane is the sent into the gas network. In the destocking phase, the SOEC is inversed in SOFC mode, which consume gas issued from the gas net. The evaluation of the energetic need, the energetic performance of the system and the economical cost of the service are the challenge of this project.
