The role of water as a resource in the production of green hydrogen

Water plays a crucial role in the production of green hydrogen. The members of German Water Partnership e.V. (GWP) already offer innovative solutions from Germany to tackle the global challenges in this area. GWP is addressing this important topic by putting it on the agenda of its work within the committees.

During IFAT Munich 2024 from May 13-17, GWP drew attention to the connection between water and green hydrogen in two sessions in the Spotlight Area Hydrogen.

Water treatment for hydrogen production

Water is the main medium in hydrogen production, and efficient water treatment that is suitable for the respective process is essential for the operation and longevity of the electrolysers. GWP members have extensive expertise and experience in this area,” says Dr. Gerd Sagawe, member of the GWP Board of Directors and board spokesman for hydrogen. In the presentation on the role of water in hydrogen production, which Sagawe gave together with Edwin Locker, CEO of Herco Wassertechnik GmbH, and Dr. Daniel Frank, DECHEMA e.V., the interested audience received important information on water requirements, water quality and production processes.

Water and hydrogen – the process chain

In the second session, Holger Paffen, EnviroChemie GmbH, and Dr. Daniel Frank provided comprehensive insights into the entire process chain associated with the use of hydrogen from water. The focus here was on the technical, logistical and ecological considerations associated with such ventures. The audience was thus given a deep understanding of the challenges and opportunities associated with water-based hydrogen production. In addition, they were informed about new technologies and best practices that are driving this field forward.

We would like to thank all the speakers and look forward to further discussions.
