KILLALA: British green hydrogen firm CPH2 has entered a non-binding agreement with Irish energy developer Constant Energy Ltd to deploy its membrane-free electrolyser technology at a planned hydrogen hub in County Mayo, Ireland.
The memorandum of understanding (MOU) follows planning approval for Constant Energy’s Killala Energy Hub, which will integrate wind and solar power to produce green hydrogen using CPH2’s proprietary Membrane-Free Electrolyser (MFE). The hydrogen will fuel a gas peaking plant, supply the local gas grid and power a filling station for fuel-cell vehicles.
Under the agreement, the companies will negotiate a binding deal for Constant Energy to purchase five 1-megawatt MFE220 units from CPH2, targeting operations between 2027 and 2028. The partnership could expand to 200 megawatts of capacity at the Mayo site over the next decade.
Jon Duffy, CEO of CPH2, called the MOU a milestone for the company’s commercial growth, citing successful field tests of its electrolyser technology. “This collaboration reinforces our role in efficient green hydrogen production,” he said.
Patrick Hynes, director of Constant Energy, praised CPH2’s technology as a “game changer” for Ireland’s renewable sector, helping capture excess clean energy and stabilize the grid.
Constant Energy, based in Limerick, focuses on green hydrogen projects in Ireland. Further updates on the deal are expected in the coming months.
