Global capacity of planned large-scale hydrogen electrolysis projects 2026, by region

By 2026, the global electroyzer capacity is forecast to reach 8.7 gigawatts as a result of large-scale hydrogen electrolysis projects planned across the globe. These projects would increase the global additional renewable capacity up to approximately 18 gigawatts. Furthermore, China is projected to account for the largest share of the large-scale electrolysis projects capacity, with Europe trailing behind. An electrolyzer is a device that uses electricity to break water into hydrogen and oxygen, thus producing hydrogen gas that can be stored.

截至2026年，全球电解槽产能预计将达到87吉瓦，这一预测源于全球范围内计划实施的大规模氢电解项目。这些项目预计将使全球新增可再生能源产能达到约180吉瓦。此外，中国预计将占据大规模电解槽项目产能的最大份额，紧随其后的是欧洲。电解槽是一种利用电能将水分解为氢气和氧气的设备，从而产生可储存的氢气。
