- 1 and 3
- None of the above
There are various ways of utilizing geothermal energy sources, which are classified as follows:
- Hot water resources. Some geothermal resources contain hot water under normal pressure between 50°C and 80°C. This hot water is again usable either for space heating or for air conditioning.
- Dry Steam Sources: Dry superheated steam, which can either be extracted directly from the geothermal reservoir or which comes out directly, may be used to run a turbine and subsequent production of electricity.
- Wet steam sources. Geothermal reservoirs, which remain under pressure, give rise to a water-steam mixture with temperatures between 180°C and 370°C. After the steam separates from water, it can be used to produce electricity or for process heat applications. The remaining water is used for space heating or for absorption-based air-conditioning systems.
