Presentation 10th February 2010 in Ljubljana

  • Introduction by Gustav R. Grob

    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


Why use geothermal heat

Why use geothermal heat ?

  • 99% of the solid rock layer has at least 1000°C

  • 0.1% of the solid rock is cooler than 100°C

  • The average rock temperature gradient

    is about 30°C per km depth world-wide

  • The geothermal heat is composed of

    about 1/3 residual heat from the creation

    of planet Earth and about 2/3 from continous

    renewable and sustainable magma generation

    .

Global Geothermal Industry Evolution by Market, 1970–2015

GEOCOGEN


Types of geothermal power plants

Types of Geothermal Power Plants

  • HDR Hot Dry Rock, removes heat from hot dry rock

    with delivered water by injection or by gravity

  • Single Flash

    overheated steam with one cycle through the turbine

  • Double Flash

    overheated steam with two cycles through the turbine

  • ORC Organic Rankine Cycle - one volatile component

  • Kalina-process uses mixture of ammonia and water

Deep Hot Rock Geothermal Energy

  • Borehole systems

  • Hydraulic fracturing by high pressureHot-dry Rock system with safely controlled

  • with relatively small energy yields closed primary water cycle in insulated wells

  • or and

  • b) Boreholes to geothermal aquifers secondary steam turbine cycle with co-

  • open systems with limited energy generationfor district heating, AC,industry and greenhouses

Disadvantages:

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.

Energy cost:

5-10 €¢ /kWh

Advantages:

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

Advantages of geothermal deep well energy co generation

Advantages of geothermal deep well energy co-generation

  • Produces electricity and heat - suitable also for cooling

  • Much lower net cost than any other energy source

  • Can be built near agglomerations and substations

  • Less energy transmission line cost – hence also

    less transmission losses than other power plants

  • Invisible, no air or water pollution and no noise

  • Ideal power source for clean electric vehicles

  • No radiation risks or other health hazards

  • Creates new clean sustainable jobs

  • No waste disposal problems !

  • Long life base-load plant

Conclusions and recommendations

Conclusions and Recommendations

  • GEOCOGEN is the most economical base load energy system

  • GEOCOGEN does not harm the health, environment & climate

  • GEOCOGEN can be installed near the energy consumption

  • A Swiss-Slovenian interdisciplinary task force is necessary

  • The EU should support a pilot plant in Slovenia

  • Engineering can be done in affordable stages

  • A national start up budget is needed
