District Heating and Cooling TREND

District heating and cooling enables the efficient integration of large-scale renewable energy sources like biomass, geothermal energy or solar thermal, and the use of various forms of excess heat and free cooling. Furthermore, it can provide flexibility on the electricity market via power-to-heat (PtH) solutions either with direct electric heating or large-scale heat pumps. Because of their various advantages, DHC systems appear in many respects as a potential backbone for coherent local energy transition strategies, mainly due to the fact that they enable local authorities and other local stakeholders to combine a variety of energy efficiency and decarbonisation leverages within an overall multi-energy system, in connection with city planning activities.
