A device that splits water into hydrogen and oxygen with electricity. Electrolysis was demonstrated in 1800, weeks after Volta announced his pile, and electrolyzers are the key technology for producing hydrogen without fossil fuels: driven by renewable electricity they yield what energy agencies call green hydrogen, the intended feedstock for clean steel, fertilizer and long-duration storage.
