Future growth of world energy production and use until 2030

Production Production Consumption Consumption

OECD Transition economies Developing countries

« Between 2000 et 2030, Energy production and consumption growth will mostly take place in developing countries »

Age of installed thermal (Fossil fuelled) power plants

In the next 50 years, 800 fossil fired power plants Will come to their end Somme will be replaced by nuclear power plants

• r by renewables

But their will also be new fossil fired plants… IEA estimate that 600 thermal power plants Will be built before 2030

Future for EGS in Europe

> Vision (2030? 2050?)

• Geothermal energy is the preferred renewable baseload

energy option in Europe

> Necessity for an European programme with an

ambitious strategic objective

• To improve EGS technology performance and reduce

production costs, hence making the huge geothermal resource available to Europe

> Some research gaps still need to be filled

Necessary Technology improvements

> Identified needs, four years ago

• Ability to predict the geothermal resource at the appropriate scale
• Reduce the cost of geothermal wells
• Cost effective methodology for reservoir stimulation
• Efficient Heat extraction and conversion processes

> What is the view today?

• Engine Mid term conference will be very informative

Conclusions

> Geothermal energy can play a very significant role among the

CO2 reduction strategies.

> Today ,many geothermal direct uses provide very efficient

ways for CO2 reduction but, only hydrothermal reservoirs of high grade resources are used for power production

> EGS technology has the highest potential in continental

Europe to increase the contribution of geothermal energy to the reduction of CO2 emissions

> Engine Coordination Action allows a development of

European research efforts and support international cooperation
