This research investigates the potential of geothermal energy to decarbonise heating in Ireland. By analysing the properties of buried Triassic sandstones, it explores whether heated groundwater can be extracted, used, and reinjected. Widespread adoption could reduce carbon emissions, provide renewable heat, and improve Ireland’s long-term energy security.

This research develops a low-temperature carbon-capture material that uses waste heat from solar panels to release captured CO₂. By reducing energy requirements from hundreds of degrees to just 70°C, the technology offers a more sustainable, scalable, and grid-independent approach to carbon capture and long-term climate-change mitigation.

Achieving a carbon-free future requires not only renewable energy generation but also major upgrades to electricity transmission. This research develops electrostatic generators that produce high-voltage DC power more efficiently and sustainably than current technologies. By reducing costs and reliance on rare materials, the work supports grid expansion and large-scale decarbonisation.
