Nowadays, the supply chain for green hydrogen is quite limited, with only a few small projects utilising this form of energy. However, rapid growth is necessary for the industry to scale up and substantially contribute to the overall energy transition. The green hydrogen value chain encompasses various interconnected elements, spanning from production to consumption, and is closely linked with the broader energy sector. The creation of some hydrogen valleys and the Irland’s vast wind potential could be used to produce hydrogen, and other electrofuels, for the decarbonisation of some of the hardest-to-abate sectors of the energy system. The project aims to investigate the potential of green hydrogen production to meet the growing hydrogen demand in Galway in the future.
