Since COP26, more and more countries are committed to net-zero by mid-century. Looking at sources of GHG emission, there are significant portions are coming from those hard to abate applications, such as aviation and long-distance transportation, cement and steel productions. To reach net-zero, wide spread of green hydrogen adoption is desired in those applications, as well as replacing grey hydrogen feedstock for ammonia, methanol productions, and petroleum refining process. As cost of renewables, such as PV and wind, continue to drop lower and lower, green hydrogen gradually becomes cost competitive. Green hydrogen enables deep decarbonization to reach net-zero emission. In this presentation, recent progress on alkaline electrolysis technology, equipment and process will be reviewed. Alkaline electrolysis has demonstrated as leading technology to enable green hydrogen adoption.
