“It’s a large load area, and we can develop our project outside of Dublin, but stabilise and feed the Dublin grid.”
The area is also rich in energy resources, including a large-scale wind farm, solar PV assets, battery energy storage systems (BESS) and other technologies like flywheels, synchronous condensers and open-cycle gas turbines (OCGT).
“It’s a very, very strong renewable area, but there’s a high amount of congestion between this area in Offaly and the Irish Midlands and Dublin. So the use case for long-duration energy storage here is congestion relief, providing grid benefits for this area, so that all of that concentration of energy can get to Greater Dublin by moving it around the peaks and moving it around the congestion of the area, so it’s going to unlock a lot of the renewables.”

Energy Dome’s technology, invented by founder and CEO Claudio Spadacini, stores energy through the adiabatic compression of carbon dioxide gas. The gas is liquified during charging and evaporates during discharging in the thermodynamic Brayton Cycle. In a closed-loop process, heat is stored during the compression process and then used to expand the CO2 gas. The gas is driven through turbines to generate electricity.
