Top 15 Hydrogen Electrolyzer Manufacturers in the World
Last Updated on 17th July 2024
Electrolyzers are devices that can split water molecules using electricity (preferably electricity produced from renewable sources) to form hydrogen. This hydrogen then can be used as zero-emission replacement for fossil fuels. Given the importance in the electrolysis of water, hydrogen electrolyzers are indispensable for producing low-cost, high-quality green hydrogen gas
