Bio inspired, fractal plate type heat exchanger

Geothermal power plants are currently run as baseload supply, due to the limited flexibility to throttle the well without scaling and liner fatigue problems. The plants are engineered for maximal efficiency at nominal output level. In future electricity grids geothermal power plants need to be able to operate with a high level of fast flexibility.

GeoSmart aims to optimise and demonstrate innovations to improve the flexibility and efficiency of geothermal heat and power systems. Demonstration installations in Belgium and Turkey will be built within the project. Fraunhofer ISE is responsible for the following three aspects within the project:

  • Evaluation of an alternative thermal storage concept based on Phase Change Materials (PCM) and using plate type heat exchangers according to the system requirements and economic feasibility.
  • Evaluation of various concepts for the integration of solar thermal heat or heat from biomass in geothermal power plants.
  • Analysis of the system integration in the European Energy/Power system by applying the energy system model ENTIGRIS of Fraunhofer ISE.
