TRANSITION IN THE HEATING AND COOLING SECTOR

3

Half of all consumed final energy in Europe.

The vast majority – 85% - of the demand is fulfilled by fossil fuels,

There thousands of District Heating Networks in Europe >10% of European heat demand.

Heat storage is by far the largest single energy storage application field in Europe.

THANK YOU FOR YOUR ATTENTION

HEATSTORE (170153-4401) is one of nine projects under the GEOTHERMICA – ERA NET Cofund aimed at accelerating the uptake of geothermal energy by 1)

advancing and integrating different types of underground thermal energy storage (UTES) in the energy system, 2) providing a means to maximise geothermal heat

production and optimise the business case of geothermal heat production doublets, 3) addressing technical, economic, environmental, regulatory and policy

aspects that are necessary to support efficient and cost-effective deployment of UTES technologies in Europe. The three-year project will stimulate a fast-track

market uptake in Europe, promoting development from demonstration phase to commercial deployment within two to five years, and provide an outlook for

utilisation potential towards 2030 and 2050.

The GEOTHERMICA project is supported by the European Union’s HORIZON 2020 programme for research, technological development and demonstration

under grant agreement No 731117.
