What is 5GDHC?


© Mijnwater B.V, Heerlen


5GDHC is an urban thermal energy grid for heating and cooling, based on the following principles:

  • Ultra-low temperatures close to end-user needs allowing the use of low grade renewable heat sources
  • Demand-driven temperature based on smart control, and decentralised installations enabling heating and cooling exchange between end-consumers thanks to a closed loop
  • Integrated heat and power networks to reduce powerpeaks


A 5th generation district heat and cold (5GDHC) grid is based on the exchange of thermal energy between buildings with different needs. The principal grid carries a low temperature flow to active and distributed substations which upgrade the temperature to the required level. Distributed thermal storage buffers the fluctuation in supply and demand of heat and cold. This architecture maximizes the share of low-grade renewable and waste energy sources.

D2Grids project

D2Grids is an Interreg North West Europe (NWE) project lasting over 3 years (2018-2022) which aims at increasing the share of RES used for heating & cooling to 20% in NWE 10 years after the project ends, through accelerating the rolling out of a proven but underutilised concept: 5th Generation District Heating and Cooling (5GDHC). 5GDHC is a highly optimised, demand-driven, self-regulating, energy management system for urban areas.
