Market Definition
An electrolyzer is a device that uses electrical energy to split water into hydrogen and oxygen. When powered by renewable or nuclear energy, it enables the production of low-emission hydrogen. The hydrogen generated can be utilized across various applications, while the oxygen produced can be released, stored, or used in industrial and medical sectors. Electrolyzers are available in multiple capacities: smaller units are used for on-site or localized hydrogen production, whereas larger systems can be paired with renewable or low-carbon power sources for large-scale hydrogen generation.
The electrolyzers market refers to the year-over-year installation of new electrolyzer capacities across different technologies. This market has been assessed across major regions, including North America, Europe, Asia Pacific, and Rest of the World (RoW).
