GEOTHERMAL TECHNOLOGY. THE HEAT FROM THE EARTH.

Geothermal energy is the form of energy generated from the heat contained within the earth: volcanos, hot springs and geysers are good indicators of how heat stored in the earth’s crust flows out via carrier fluids such as water and steam. The temperature inside our planet increases with depth according to a geothermal gradient of 3°C every 100 meters. There are also zones where the flow of heat is much greater (9-12°C every 100 meters).

A geothermal power plant differs from a traditional thermoelectric plant in that extra apparatus is necessary to treat the fluid that comes from underground and to extract the incondensable gases (mainly CO2) that are present in steam. A geothermal power plant consists of a steam generator (energy source), a turbine, a generator for electricity, and a condenser for condensation.

In geothermal terms Italy is the” hottest” country in Europe, indicated by the number of volcanos, geysers and thermal springs.
