VDI 4635 Blatt 3.1
Power-to-X; Hydrogen production through water electrolysis
Power-to-X; Wasserstofferzeugung durch Wasserlektrolyse
Brief description
The guideline deals with the use of electrical energy for electrolytic water splitting. It defines system limits as well as system and cost parameters that are relevant for the description of water electrolysis systems. The most important basics for understanding the three available technologies - alkaline electrolysis, PEM electrolysis and high-temperature electrolysis - are explained. In addition, hydrogen production by chlor-alkali electrolysis is also briefly covered. Important aspects of water electrolysis such as the provision of direct current, the possibility of dynamic operation, the measured variables required for balancing and the compression of hydrogen are addressed. The topic of hydrogen production is dealt with in the VDI 4635 "Power-to-X" series of guidelines. Other sheets deal with CO2 provision, methanation and ammonia synthesis, for example.
