Electrolysers generate hydrogen and oxygen with little impurities. These can be extensively dispersed and suited to satisfy renewable energy systems'' hydrogen
Producing Hydrogen, Safely. The process of producing hydrogen using water and electricity is called electrolysis. Electricity breaks water down into its base elements, hydrogen, and oxygen, in a unit called an electrolyzer. An electrolyzer can range in size from small devices to large-scale, central production facilities.
Electrolysis of water, using renewable electricity, is the sustainable option to produce green hydrogen as an attractive low-carbon energy carrier. To respond to the growing demand for renewables-based hydrogen, an extraordinary expansion of the market for electrolysers is needed linked to a significant capacity increase in the manufacture and
