Air power for east AntrimLast updated on 11/05/2016
It sounds like science fiction but appears to be technologically feasible.
A local renewable energy company wants to store compressed air deep underground – releasing it when needed to power electricity generators.
Gaelectric, a major developer of wind farms, is planning the £300m development near Larne.
It aims to compress air inside caverns located deep within the salt layers running under East Antrim.
According to Gaelectric the process has already been applied successfully for several decades in the US and Germany.
The company says it hopes to start building the facility early next year
