Abstract
Electrolysis by means of Solid Oxide Cells (SOC) offers unique possibilities with respect to production of sustainable fuels from carbon dioxide and steam. High temperature waste heat can be utilized to reduce the consumption of electric power and the ability to co-electrolyze carbon dioxide and steam makes it possible to generate synthesis gas suitable for production of a range of fuels. The synergies between SOEC and production of SNG or methanol will be explored. The requirements for feedstock purification, limitations due to potential carbon formation problems and overall efficiencies will be addressed taking into account the properties of existing as well as emerging SOEC electrodes.
