Is this part of the future for wind power, or just another doomed idea?
The search for new ways to produce energy are often complicated and controversial – and in Northern Ireland, a project to compress air into caverns under the seabed is no different.
It will be used, along with gas, to run turbines when the wind does not blow.
However some are worried that the process could be damaging to the natural habitat, as a short BBC video reports.
Well, it’s different if nothing else.
