New power-to-gas process

The Montanuniversit├Ąt Leoben is working with partners from industry and scientific research on new ways of storing surplus energy from regenerative energy sources that fluctuate strongly. By means of a power-to-gas process, renewable electricity can be stored in the form of chemical energy carriers, which are typically hydrogen or methane. While conventional power-to-gas systems are based on the electrolysis of water with an optional subsequent methanation step, the aim of the research is to combine the relatively recent technology of co-electrolysis of CO2 and H2O in solid oxide cells (SOECs) with catalytic methanation.
