How does electrolysis work?

Electrolysis is the process of using electricity to split water molecules into hydrogen and oxygen. If the electricity used to split the hydrogen and oxygen atoms is renewable, this hydrogen is called green hydrogen. Green hydrogen can be used in the same way as all other types of hydrogen. You can add it to natural gas and burn it in thermal power or district heating plants. You can use it as a precursor for other energy carriers, from ammonia to synthetic hydrocarbons, or to directly power fuel cells in cars and ships, for example.

What are the advantages of its production?

The benefit of green hydrogen through electrolysis is that carbon never comes into play. With green hydrogen production, there is no carbon to dispose of within the process.
