Application
In the electrolyser, renewable energy is used to split water (H2O) into its individual components hydrogen (H) and oxygen (O). Green hydrogen is thus produced in a CO2-free cycle. In the alkaline electrolyser, potash lye acts as the electrolyte, which is not consumed in the process. Oxygen is produced as a by-product. Level measurement is used to regulate both the concentration of electrolyte and the inflow of water.
