How can an emission-free hydrogen cycle be created?
The only drawback with hydrogen, however, is that it is not an energy source like the sun or coal, but a (secondary) energy carrier which first has to be produced. In industry hydrogen is produced by splitting methane, the main component in natural gas. However: This production releases carbon dioxide, which is a burden on the environment. The long-term objective, however, is that of creating a truly emission-free energy future with hydrogen. One possible way is electrolysis, which breaks down water with the aid of electricity – which should be produced from renewable energy sources of course – into hydrogen and oxygen.
