Title:
ELECTROLYSIS SYSTEM AND ELECTROLYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2021/220667
Kind Code:
A1
Abstract:
An electrolysis system (1) comprises at least one H2O electrolysis device (10) for electrolyzing water to generate hydrogen, and at least one CO2 electrolysis device (20) for electrolyzing carbon dioxide to generate carbon monoxide. The electrolysis system (1) comprises a co-electrolysis device (30) that co-electrolyzes water and carbon dioxide and generates a smaller amount of hydrogen per unit time than is generated by the at least one H2O electrolysis device (10), and that generates a smaller amount of carbon monoxide per unit time than is generated by the at least one CO2 electrolysis device (20).
