1. Geothermal in Portugal Dr. Ana PalmeroProf. Armando OliveiraFEUP | Faculty of Engineering, University of Porto Public conference organized by ALEC, BORDEAUX, 18th February 2020 Geothermal in Portugal
2. Local geothermal energy solutions in PortugalGeothermal resourcesTemperatureVery low enthalpy: T<30°C Low enthalpy: 90>T>30 °C Medium enthalpy: 180>T>90 °CHigh enthalpy: T> 180°CDepthShallow Geothermics : <250 mGround source heat pumps (GSHP)Deep Geothermics: >400 m Enhanced Geothermal Systems (EGS)There are three main types of geothermal energy systems (with different examples in Portugal): Direct use and district heating systems; Electricity generation power plants; Geothermal heat pumps (building heating or cooling);Portuguese mainlandPortuguese islands (Azores)
3. Portuguese mainland:According to the knowledge, there are only conditions for the use of low enthalpy applicationsPortuguese islands (Azores):There are 48 geothermal occurrences of low enthalpy in Azores islands.High enthalpy geothermal resources are present and geothermal power stations were installed since 1980. São Miguel IslandPico Vermelho + Ribeira Grande (27.8 MWe capacity and annual energy production of 171.6 GWh- year2016) Supply over 44% of the electrical consumption of the islandTerceira islandPico Alto (4 MWe capacity) 16% of the island electrical consumptionLocal geothermal energy solutions in Portugal
4. Local geothermal energy solutions in PortugalDensity of surface heat fluxGeothermal occurrencesMore than 60 occurrences!Low Enthalpy Geothermal Resource in Portugal mainland
5. Some ExamplesCaldas de Chaves (nº20), 190 m deep,76°C. Started in 1982. Distric heating (swimming-pool, hotel heating, greenhouse heating). São Pedro do Sul (nº55), 500 m deep, 69°C for direct uses (bathing and swimming). Another hole with 200 m deep and 67°C for greenhouse heating, producing tropical fruits.Caldas de Monção (nº38), 47°C for direct uses (heating of the hotel, swimming pool and building). Started in 2015.Use of geothermal occurrencesLocal geothermal energy solutions in PortugalLow Enthalpy Geothermal Resource in Portugal mainlandGeotherm & ThermalismThermalismThermalism &BottlingBottling
