Background

Green hydrogen plays a major role in the net-zero greenhouse gas-reduction strategy of the European Union. It will replace fossil fuels in numerous sectors i.e., transportation, aviation, and the steel industry. In the production of green hydrogen, water is electrolyzed and decomposed into hydrogen (and oxygen). Therefore, the reliable and economical supply of green hydrogen is highly related to the also reliable and economical supply of water. Water supply can be fulfilled from different resources such as seas (salty water) and rivers (freshwater). Different resources may entail additional processes such as the desalination of seawater. On the other hand, using limited sources of freshwater resources might cause some social problems. To this end, an efficient water supply design is crucial to enable socially, economically, and environmentally efficient hydrogen production.

Guiding Questions

• What are the technological foundations of hydrogen production? How are the production process and the final product influenced by different sources/qualities of water?

• What are the requirements and criteria for the design of water supply systems for hydrogen production?

• Considering techno-economical criteria, which supply design from the supply point to the production point outweighs the other options? Under which conditions?

• From social, economic, and ecological perspectives which supply designs are feasible and favorable?
• How can the total demand of production plants be satisfied using a set/network of supply sources?
