In an electrolyser, electricity is used to break water into hydrogen and oxygen in a process called electrolysis. If the electricity comes from renewable sources, the hydrogen produced is green hydrogen. An electrolyser converts electrical energy into chemical energy, or electrons into molecules.
The Process of Electrolysis
The process of electrolysis involves applying an electric current to water, which causes the water molecules to split into hydrogen and oxygen. This is done in an electrolyser, a device that uses electricity to break the chemical bonds of water.
Conversion of Electrical to Chemical Energy
During electrolysis, the electrolyser converts the electrical energy into chemical energy, with the electrons being converted into hydrogen and oxygen molecules. This process is highly efficient, with the hydrogen and oxygen being produced with a high degree of purity.
