Making synthetic fuels for the industrial sector via solid oxide electrolysis and catalytic upgrade using recovered carbon dioxide and residual biomass

This work focuses on alternative gaseous fuels (Synthetic Natural Gas and Hydrogen) for natural gas substitution in the industrial sector at a regional level. Different pathways have been analyzed for the production of the above-mentioned alternative fuels. In all pathways involving SNG process that combines high-temperature co-electrolysis in a solid oxide electrolysis cell (supplied with renewable electricity) to a downstream catalytic reactor that upgrades further the electrolysis-derived syngas are investigated. In case of hydrogen only the high-temperature co-electrolysis in a solid oxide electrolysis cell. The results are then compared on regional level.
