The storage of renewable energy is an important point in the roadmap of the European energetic plan, following a development strategy of low-carbon technology. In this context the development of flexible power-to-liquid (P-to-L) and power-to-gas (P-to-G) processes for energy storage is one of the most promising solutions for the smooth transition from a driven fossil fuel society to a driven renewable sources society. In this regard, Fischer-Tropsch (FT) synthesis is used to obtain valuable chemicals from syngas (H2/CO mixture) through a catalytic reaction. The syngas can be obtained from renewable sources such as the co-electrolysis of CO2 + H2O in a SOEC electrolyzer.
