Our flagship Islandmagee gas storage project was first established in 2010 when a layer of salt was discovered 1500m underneath Larne Lough. This salt layer is ideal for the establishment of underground gas storage caverns.


It is the only largescale gas storage project in the entire island of Ireland and lends itself naturally to boosting the security of energy supply to the entire island. The fact that gas will be stored in salt caverns allows for high deliverability rates into and out of the store, helping to balance the gas network in times of peak stress. The Islandmagee facility is expected to provide over 25% of the UK’s natural gas storage capacity (based on 2018 data) and will support the growing demand for gas-fired power development and renewable energy generation throughout the United Kingdom and the Irish Republic.


In October 2020, Oxford Analytica provided an independent thought leadership report for Harland & Wolff Group Holdings plc (then Infrastrata plc).

The report provided an assessment of the long-term importance of domestic gas storage and the economic, political and environmental impacts on Northern Ireland, the rest of the UK and Ireland.
