As of 2023, operational hydrogen projects using electrolysis had a combined production capacity of some ******* metric tons. By 2030, this figure is expected to increase to nearly *** million metric tons when considering all proposed projects.
Production capacity of low-carbon hydrogen worldwide in 2023, with an estimate for 2030 based on announced projects, by production pathway and status
(in million metric tons per year)
* "Other" largely refers to biogas technology. Only projects specifically aimed at climate change mitigation and commissioned after 2000 were considered. Figures were rounded.
