Abstract (en)
[origin: WO2021122584A1] The invention relates to a power-to-X system (1) for the utilization of off-gases, comprising an electrolyzer (2) for generating hydrogen H2 and oxygen O2, a unit, connected to the electrolyzer (2), for processing the hydrogen H2 (3), for removing any remaining water H2O and oxygen O2 from the generated stream of hydrogen H2, a compressor (4), connected to the unit for processing the hydrogen H2 (3), for compressing the hydrogen H2, and a chemical reactor (5), connected to the compressor (4), for producing a synthesis gas (6) consisting of hydrogen H2 and carbon dioxide CO2 that can be added. The invention further relates to an oxy-fuel combustion system (7) to which non-condensable off-gases (8) from the chemical reactor (5) and oxygen O2 from the electrolyzer (2) can be supplied, and carbon dioxide CO2 generated during the combustion of the off-gases (8) in the oxy-fuel combustion system (7) can be returned to the stream of hydrogen H2 downstream of the electrolyzer (2) via a return line (9).
