Presentation 10th February 2010 in Ljubljana
GEOCOGEN Concept and International Potential
2)Dr. Gustav Hans Weber (phys.)
The Thermodynamic Process and Life Expectation
3)Martin Weber, MSc (chem.)
The Chemistry of Geothermal Systems
High Temperature Isolating Concrete
followed by project team implementation discussions
is about 30°C per km depth world-wide
about 1/3 residual heat from the creation
of planet Earth and about 2/3 from continous
renewable and sustainable magma generation
Energy Cost Comparison
Global Geothermal Industry Evolution by Market, 1970–2015
with delivered water by injection or by gravity
overheated steam with one cycle through the turbine
overheated steam with two cycles through the turbine
Earth Quake Risk !
Problem: Kirchhoff‘s law
of the easiest way
Deep Hot Rock Geothermal Energy
a) Water is finding way of lowest resistance
= limited Energy yield
b) Only in hydro geologic strata often far from consumers.
Often high energy transport cost.
Often limited to heat production only.
5-10 €¢ /kWh
No yields by hazard !
Super performance (GW).
No fuels or waste problems.
Excavated materials re-used.
Base load power plus heat
Energy cost: 2–4 €¢/kWh
less transmission losses than other power plants
Example NRW Subsitution of Nuclear & Coal
Permits & PPA
Partners (EU etc.)
Start of operation
Detrmination of Team
