Paris basin france

Paris Basin, France

  • 34 district heating projects since 1969

  • Thermal capacity equivalent to 308 MW

  • Provides heating for over 150,000 units

  • Over 250,000 tonnes of CO2 emissions avoided


Benefits from using geothermal energy

Benefits From Using Geothermal Energy

  • Available for the long-term

  • Near zero greenhouse gas emissions

  • Sustainable

  • Reliable

  • Not subject to significant price volatility

  • Can be integrated with existing infrastructure


Limitations of deep geothermal

Limitations of Deep Geothermal

  • Energy produced is non-transportable

  • Project development requires significant upfront investment

  • Timing of development schedule


Potential uses of geothermal energy

Potential Uses of Geothermal Energy

  • Heating buildings in new industrial park developments

  • Heating homes in new residential subdivisions

  • Retrofitting commercial buildings

  • Pre-heating industrial boiler or process water

  • Drying ethanol plant distillers grain

  • Tourism

  • Greenhouses

  • Electricity generation
