// Water electrolysis and system concepts

ZSW benefits from its many years of experience in the design, dimensioning, installation, commissioning and pilot operation of electrolysis plants and also has expertise in data evaluation for these plants. The department currently operates an alkaline pressure electrolysis system and a PEM pressure electrolyser that uses either direct gas application or a pressure buffer. A new test bench also provides even more methods to test electrolysis blocks and individual system components.
