The Galway Hydrogen Hub, GH2, consortium has proposed to develop Ireland’s first hydrogen valley, a regional ecosystem that links H2 research, production, and distribution with end-users. The consortium wants to develop a hydrogen valley in the Galway region, similar to those in other European countries. It is a regional ecosystem that links H2 research, production, and distribution with various end-users such as transport and industry. This is to position Galway as the home of Ireland’s first hydrogen valley, providing green hydrogen for use in transport and industry. The intended hydrogen transport hub could be fully operational by the second half of 2024.The GH2 is a consortium consisting of seven members.

It emits only water vapor into the atmosphere. Most recognise green hydrogen as crucial to making the cuts in GHG emissions while reducing the need to import fossil fuels.
