Solid oxide electrolysis cells

Solid oxide electrolysis cells (SOECs) have the potential to become one of the core technologies in Power-to-Gas/Liquid processes for the renewable electrochemical production of fuels and chemicals. SOECs can either electrolyze steam to produce green H2 (cf. Figure), perform H2O/CO2-co-electrolysis to produce syngas or directly electrolyze CO2, thus providing multiple sustainable pathways for the production of highly valuable fuels or feedstock molecules for the chemical industry from electricity. By thermally integrating the electrolyzer module with downstream synthesis steps, unrivalled energy efficiencies of up to 90% on integrated system level can be achieved. Core targets of our research in this field is the development of detailed multi-scale and multi-physics models that can be used to optimize the conceptual design of electrolysis cells, stacks and systems for the sustainable production of high-value platform molecules such as CH4.
