In water electrolysis, electrical energy is used to split water molecules (H₂O) into their components: H₂ as the main product and O₂ as a by-product.

In addition to the stacks in which the electrochemical process is implemented, the electrolysis system contains all the necessary components and subsystems to guarantee an optimized process. Particular attention is paid to process water treatment, heat management and power supply. The gas treatment completes the system and guarantees the ambitious product qualities.
