What is the current status of water electrolysis for hydrogen production?
Water electrolysis for hydrogen production is currently progressing and several major electrolysis technologies have been developed and optimised for practical applications. They mainly include alkaline electrolytic water (ALK), proton exchange membrane electrolytic water (PEM), high-temperature solid oxide electrolytic water (SOEC) and anion exchange membrane electrolytic water (AEM). Each of these technologies has its own advantages
