Kestrel is a practical, policy-aligned solution that secures Ireland’s energy system today, while preparing it for tomorrow.
Kestrel is a national-scale energy storage project designed to strengthen Ireland’s energy security and support the transition to a lower-carbon energy system. Led by ESB Generation and Trading, Bord Gáis Energy and dCarbonX, the project would repurpose the decommissioned Ballycotton gas field for strategic underground storage.
Ireland currently has no indigenous long-duration gas storage, leaving the energy system exposed to supply disruption, price volatility and wider system stress. Kestrel would help address this gap by providing a secure, proven and scalable storage solution that complements other energy security measures.
In the near term, Kestrel would support resilience through natural gas storage. Over time, the same infrastructure is intended to support green hydrogen or biomethane storage, helping Ireland integrate more renewable energy while maintaining a secure and reliable energy system.
Ireland currently has 0 days of gas storage, compared with an EU average of 79 days. The UK has 6 days of storage.
Updated geological and operational analysis confirm capacity for at least 90 days of strategic reserve, based on average daily consumption.
CEPA modelling estimates €4.6 billion per month economic loss to the Irish economy from a full gas disruption.
Natural gas was safely stored in Kinsale from 2001–2017.
All upfront capital and development expenditure is borne by the consortium.
Kestrel is being engineered from day one for green hydrogen, making it a future-proof asset.
