A new €2 billion renewable energy facility is being planned for Co Carlow.
The long-duration energy storage facility is proposed to be located outside the town of Tullow by Irish company Net Zero Energy (NZE).
The facility, planned for Rathrush Green Energy Park, will use excess renewable energy produced from wind and solar farms.
The excess energy is currently being lost due to inadequate grid capacity and lack of demand at certain times, to generate green hydrogen, according to the company.
