Hydrogen can provide data centres with zero-emission backup power, support grid balancing, and reinforce Ireland’s green credentials. The next generation of facilities could evolve into hybrid energy hubs consuming, storing, and even supplying renewable energy to the grid. The challenge: data centres vs grid constraintsThe scale of Ireland’s data economy is immense. Electrolysers, located on or near data campuses, can convert curtailed wind power into hydrogen for storage or use in clean backup generation. Ireland’s ambition to be Europe’s digital host depends increasingly on its ability to harvest and store its renewable energy.
