Smart and local reneWable Energy DISTRICT heating and cooling solutions for sustainable living

Project description

Decarboning urban heating and cooling systems

District energy is a proven solution for delivering heating, hot water and cooling services through a network of insulated pipes – from a central point of generation to end users. It requires a vast amount of energy that when sourced from fossil fuels, accounts for a major portion of a city’s greenhouse gas emissions. The EU-funded WEDISTRICT project will demonstrate an integrated district heat and cooling (DHC) network combining renewable energy sources, thermal storage and waste heat recovery at low temperatures. Innovative concepts include use of molten salts for thermal storage, interaction with other energy networks, and end-user involvement through ICT solutions. The integrated DHC solution proposed by WEDISTRICT will significantly help decarbonise urban heating and cooling systems.


The overall objective of WEDISTRICT is to demonstrate DHC as an integrated solution that exploits the combination of RES, thermal storage and waste heat recycling technologies to satisfy 100% of the heating and cooling energy demand in new DHC and up to 60-100% in retrofitted DHC. For this purpose, the focus of WEDISTRICT is large-scale replication of best practice: better valorisation of local resources, like renewable and waste heat by making District Heating and Cooling networks more efficient in relation to the use of new resources. In parallel, systems will evolve to provide even more flexible solutions by the integration of innovative molten-salts based thermal storage, the interaction with other energy networks (electricity and gas) and the involvement of end-users (operators and consumers) through ICT-based control and decision making. Finally, to enable significant expansion, cost-effectiveness will be enhanced by transitioning from handicraft to more industrialised solutions that integrate LEAN methodologies to optimise processes and lower costs.
