Abstract
Wind and solar power are troubled by large fluctuations in delivery due to changing weather. The surplus electricity can be used in a Solid Oxide Electrolyser Cell (SOEC) to split CO2+H2OCO2+H2O into CO+H2(+O2) which can be catalyzed into various types of synthetic fuel using a suitable catalyst. H2OH2O electrolysis with a new SOEC resulted in a record breaking current density of -3.6A/cm2 at a cell voltage of 1.48 V. Assuming the surplus electricity to cost 3.6 US$/GJ, the H2H2 production price is estimated to 5 US$/GJ equivalent to 30 US$/barrel crude oil or to 0.6 US$/gge (gallon of gasoline equivalent).
