In 2021, the total capacity of electrolyzers for hydrogen production commissioned that year amounted to * megawatts electrical (MWe), roughly a four-fold increase in comparison to the previous year. Vehicle fueling has been the main hydrogen application since 2019 - with an electrolyzer capacity of *** MWe in 2021, up from less than *** MWe in 2010.
