There is an advanced methodology for harnessing geothermal energy - the "Self Contained In-Ground Geothermal Generator" (SCI-GGG) and “Self Contained In-Ground Heat Exchanger" (SCI-GHE) systems, shortly called "Scientific Geothermal Technology". It is a new approach for harnessing geothermal energy – a much better way than conventional geothermal systems and/or experimental Enhanced Geothermal System (EGS), both of which have serious shortcomings.
For more information please visit: www.GeothermalWorldwide.com . (See “Our Technology” / SCI-GGG and SCI-GHE systems).
In summary – with SCI-GGG system electricity is produced down at heat source and transported up to the ground surface by means of a cable. No pollution emitted during production process. No needs for hydro-thermal reservoirs although not limited to hot rocks.
The "Self Contained In-Ground Geothermal Generator" SCI-GGG system consists of a boiler, turbines, generator and condenser. The boiler is exposed to source of heat. The engine compartment is thermally insulated and cooled with separate closed loop system which is engaged with third closed loop system on the ground surface and produces additional electricity.
The "Self Contained In-Ground Heat Exchanger" (SCI-GHE) system is an integral part of the "Self Contained In-Ground Geothermal Generator" (SCI-GGG) system which functions as a heat exchanger (closed loop cooling system). It is used separately as an independent heat exchanger apparatus.
The SCI-GHE system consists of a closed loop thermally insulated line with 2 coiled pipes (heat exchangers) and a few in-line pumps. The first heat exchanger is lowered to the bottom of the wellbore at the heat source and the second heat exchanger is coupled into binary power unit on the ground surface which produces electricity by using Organic Rankine Cycle (ORC). Electricity is then transported through an electric grid.
