The presentation discusses deep geothermal energy by GT Energy, a leader in this field in Ireland and the UK. It outlines the benefits and applications of geothermal energy, including its low visual impact, independence from climatic conditions, and potential for energy security. The document highlights ongoing projects, achievements, and the future potential for geothermal plants across Ireland.

4. CURRENT PROJECTSPipeline of projects developed to include;35MWth3.5MWe

5. What is geothermal energy?Is a natural form of renewable energyIs energy generated from the decay of natural materials at the earths coreEstimated temperature of the earths core is 6,000 CHarnessed for centuries throughout the worldRemains largely untapped4,000times the earth’s energy needs could be met by geothermal energy

6. How is geothermal energy harnessed?DrillingA geothermal well doublet system drilled to a depths of up to 5,000 metresExtractionHot geothermal fluids are pumped to the surface through a production well;Heat ExchangeThe heat is extracted through a heat exchanger and transferred to a working fluid

7. The cooled geothermal fluid from the heat exchanger is returned to the geothermal reservoir through a re-injection wellDistributionElectricity, to a grid

9. What can it be used for?Provision of heat to district heating schemesGeneration of electricityHeat supply to large horticulture growersHeat supply to large Universities, HospitalsDistrict coolingCooling for large data centresGeothermal Energy

10. Low visual impact, ideal for urban locationsTHE BENEFITSLow visual impact makes it ideal for urban locationsIt is not dependent on climatic conditions such as wind and solarIt is an indigenous supply of sustainable energy that enables governments to overcome security of supply riskIt is not subject to fuel price volatilityHas minimum visual impact on the surroundsAssists governments achieve energy and emission targetsIt is a proven technology unlike many other renewable technologies
