Defined: Energy that is generated by converting hot water or steam from deep beneath the Earth’s surface into electricity. Unique renewable Natural Energy Flow Heat Mining Enthalpy The Heat Source: The Heat Source Tiny quantities of radioactive isotopes liberate heat as they decay Core heat transfer through convection Accessible in locations where heats interior is brought within reach Lithospheric Plates Significant heat flow Volcanic activityThe Heat Source Cont’d: The Heat Source Cont’d High enthalpy systems are divided into two categories Vapor Dominated Best and most productive Free of liquids Liquid Dominated Relies on water at boiling point Often results in steam “flash” Two-phase zoneGeothermal Potential: Geothermal Potential Nature of the resource Fluid Temperature Salinity Fluid Pressure Gas Content Economies of Scale Maximum efficiencyFour Main Types: Four Main Types Dry steam power plant Single flash steam power plant Binary cycle power plant Double flash power plantDry Steam Power Plant: Dry Steam Power PlantSingle/Double Flash Steam: Single/Double Flash SteamBinary Cycle Power Plant: Binary Cycle Power PlantGround Source Heat Pump: Ground Source Heat PumpGlobal Capacity: Global Capacity Worldwide use of geothermal 9.3GW 28 GW used directly for heating 100GWt through ground-source heat pumps Potential for 65-138GW MIT claims 100GWe by 2050 0.3% of US energy consumptionEnvironmental Impact: Environmental Impact Gaseous emissions Less than 1/10th of coal-fired carbon emissions Dissolved gasses Land use Noise Potential ground subsidenceGeothermal Usage: Geothermal Usage Iceland generates 26.5% of energy from geothermal .1% Fossil fuels 73% Hydro In the US Alaska (1 Plant) California (4.8% of electrical energy, 2.4GW installed capacity) Hawaii (30MW on largest island, 20% of electrical energy) Nevada(15 plants, 254MW) Utah (reconstructed developing plants)Applications in Belize: Applications in Belize Belize is the only country in Central America that does not have the potential for geothermal energy according to the US Department of EnergyQUESTIONS?!!: QUESTIONS?!!
