Europe and Australia lead the scene, with half of the capacity together, followed by Latin America with around 15% of the announced projects. If all the projects currently in the pipeline are realised, global electrolysis capacity could reach 170-365 GW by 2030. At the same time, announcements from the Chinese market indicate a trend toward larger projects, in the hundreds of MW scale.īased on the current pipeline of projects under development and their expected operation dates, global electrolysis capacity could reach almost 3 GW by the end of 2023, a more than four-fold increase in total capacity compared to 2022. If the Ningxia Solar Hydrogen Project in China – a 150 MW project which accounted for almost two-thirds of the global additions in 2021 – is considered as an outlier, the 2022 growth was aligned with previous years.

There was significant growth in annual capacity additions in 2021, a record year for deployment, with more than 200 MW of electrolysis capacity becoming operational.ĭespite promising project announcements, capacity additions slowed down to 130 MW in 2022, with total installed capacity reaching about 690 MW. However, the pace of deployment of electrolysers for dedicated hydrogen production only started to accelerate in the late 2010s. Electrolysers are already widely used in the chlor-alkaline industry to produce chlorine and sodium hydroxide, with installed capacity having reached more than 20 GW.
