The company (formerly Portland Gas plc) demerged from Egdon Resources plc on 16th January 2008, and was admitted to the AIM market on 17th January 2008. The name change to InfraStrata plc was effected on 15th December 2009.
Since that time, the company investigated a broad range of potential energy infrastructure projects around the world, and in November 2015 a decision was made to initially focus on developing an underground natural gas storage facility at Islandmagee in County Antrim, Northern Ireland.
Between June 2017 and July 2018, a new executive team, supported by professional consultants and experienced non-executive directors, was appointed, and new funding was secured. This enabled FEED to be commenced in April, with completion due December 2018.
