Over 4 years the GEMINI project will help reduce Greenhouse Gas Emissions associated with heat production, a goal central to EU, UK and Irish strategies to meet 2050 emissions targets. Heat energy from the Earth will be used to power large-scale heating and cooling systems in public sector buildings: swimming pools, housing projects, utilities offices and a university campus. The project is being led by Codema, Dublin’s Energy Agency, and is supported by the PEACEPLUS programme managed by the Special EU Programmes Body (SEUPB) with matched funding from the Department of Environment, Climate and Communications, Ireland and the Department for the Economy, Northern Ireland. The project brings together key actors on the island of Ireland to promote cross-border cooperation in the renewable energy sector.
