Bord Gáis Energy has teamed up with ESB and dCarbonX in the development of the Kestrel Energy Storage Project.

The utility company will join ESB and dCarbonX on a co-equal basis. ESB and dCarbonX have been working together in terms of the assessment and development of Irish offshore green hydrogen subsurface storage opportunities since 2021.

Kestrel focuses on the proposed re-development of the decommissioned gas reservoirs at the Kinsale Head gas field for large-scale green hydrogen energy storage, initially of natural gas, ultimately transitioning to green hydrogen.

The National Hydrogen Strategy has identified that long duration storage is essential to the future cost competitiveness and price resilience of hydrogen and that geological storage solutions will be needed to support this.

This project represents an opportunity to deliver large scale energy security of supply for Ireland which will support the expansion of renewable energy production and support the development of an indigenous green hydrogen sector in Ireland in the years ahead.

ESB and Bord Gáis Energy both operate significant electrical generation capacity at their onshore Aghada and Whitegate gas-fired power stations in Cork. By integrating essential large-scale storage, it will support the transition of these stations to net zero emissions in the future.

Dave Kirwan, Managing Director, Bord Gáis Energy, said: "Decarbonising Ireland's energy system while maintaining security of supply is critical in the context of our growing economy. As we help to deliver the green transition, there will be an ever-increasing role for gas and ultimately green hydrogen and we are delighted to partner with ESB and dCarbonX and deliver the infrastructure for a greener future. Together with the support of Centrica, we have the skills, vision and financial backing to help Ireland achieve its ambitious Climate Action Plan targets."

Jim Dollard, ESB Executive Director, Generation and Trading, stated: "Mirroring the developments across Europe, ESB recognises the importance of large-scale energy storage and the role that green hydrogen will play in enabling a net zero future. Bord Gáis Energy’s entry into the Kestrel Project is to be welcomed and will be vital to deliver this key strategic asset that can that help Ireland to meet its climate objectives, whilst also supporting energy security."

Tony O’Reilly, dCarbonX CEO, said: "The participation of Bord Gáis Energy in the Kestrel Project is a perfect fit given their extensive experience and exemplary track record operating in the Cork Harbour region. In addition, their parent company Centrica, a leading international energy player, operates the UK’s largest gas storage facility at the offshore Rough field, which is also being assessed for future hydrogen storage potential. These capabilities, combined with those of ESB and our shareholder Snam, provide a significant strategic capability that can deliver large scale energy storage for the benefit of Ireland."
