Capacity of electrolysers for hydrogen production by commissioning year by regions, 2010-2020

Notes

2020 values represent estimates based on successful completion of all projects publicly stating a 2020 commissioning data as of the start of 2020. MWe = megawatts of electricity input; in some cases this is calculated from hydrogen output volumes if otherwise not stated. Includes electrolysers for the supply of hydrogen for energy purposes or as an alternative to fossil fuels in industry, such as chemical production and oil refining.
