Hydrogen + Oxygen are produced

An electrolyser uses electricity to separate water into hydrogen and oxygen in a process called electrolysis. Through electrolysis, the electrolyser system creates hydrogen gas. The oxygen which remains is released into the atmosphere or can be captured or stored to supply other industrial processes.

The hydrogen is stored locally in low pressure storage vessels.

At its most basic, an electrolyser contains a negative charge, positive charge and a membrane. The electrolyser also contains pumps, vents, storage tanks, a power supply, separator and other components. Water electrolysis is an electrochemical reaction which takes place within the cell stacks. Electricity is applied to the negative and positive charges and causes the water (H₂0) to split into its component molecules, hydrogen (H₂) and oxygen (O₂).
