SAPHEA - Integrating geothermal heating and cooling networks in Europe


SAPHEA addresses the market uptake of geothermal energy and underground heat storage supplied multivalent heating and cooling networks (‘geoHC networks’, for more information see chapter 1.2), which operate at temperatures of less than 30°C and up to around 100°C. The range of applications of geoHC networks starts at local-scale networks with capacity levels of at least 500 kWth, including sub- and peri-urban regions across Europe. SAPHEA will address the installation of new geoHC networks (greenfield installations or replacement of individual heating and cooling solutions), as well as the retrofitting of existing, fossil fuel-supplied heating networks.

SAPHEA’s overall goal is therefore to address the prevailing barriers of renewable heat by developing and supporting market uptake measures for enabling geoHC networks to significantly contribute to the European HC sector. This in turn will contribute to a gradual and continuous replacement of fossil fuels while at the same time increasing the use of on-site available, low-exergy RES in order to reach the 2050 zero net emissions goals of the European Union.
