Form Energy has announced a partnership with Irish developer FuturEnergy Ireland to jointly deploy the 10 MW/1 GWh Ballynahone Energy Storage iron-air battery project in the northwest of Ireland, planned to come online in 2029. The battery system will be located in southwest of Buncrana town, near the Trillick substation in County Donegal. The project was proposed in 2024 and subsequently approved the same year with a 10-year permit. Using iron, water, and air, Form Energy claims that its battery technology is able to store very large amounts of energy at a lower cost compared to other technologies.
The Irish government’s 2024 Electricity Storage Policy Framework singled out long-duration energy storage (LDES) as crucial for future-proofing the island country’s national grid due to its ability to provide round-the-clock power.
