The H2020 REWARDHeat project is revolutionising district heating and cooling (DHC) networks by developing advanced solutions that significantly lower source temperatures and utilise thermal energy storage through smart controls. These innovations, including thermal energy storage-integrated substations and electric-driven heat pumps, tap into low-grade waste heat from urban areas, industrial processes, supermarkets, data centres, and natural sources like lakes and rivers.

By predicting loads 24 hours ahead and optimising heat harvesting, REWARDHeat is reducing DHC networks' CO2 emissions by over 35,000 tonnes annually. The project supports eight demonstration networks, fostering a sustainable approach and aiding Europe's Fit for 55 goals in an investment worth more than EUR 20 million.
