Periodic Reporting for period 2 - WEDISTRICT (Smart and local reneWable Energy DISTRICT heating and cooling solutions for sustainable living)
Período documentado: 2021-04-01 hasta 2022-03-31
Heating and cooling in EU accounts for 50% of total energy consumption. 70% of this energy is generated from fossil fuels.WEDISTRICT project is born with the objective of demonstrating 100% fossil free heating and cooling solutions by optimally integrating multiple sources of renewable energies in new and existing DHC systems. Integration of 9 upgraded renewable solutions for DHC generation into 4 real DHC sites in Spain, Romania, Poland and Sweden will be performed within the project. All of this, in a holistic context, smartly managed by ICT-integration, sustainable business models and engagement of citizens.
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. The focus of WEDISTRICT is large-scale replication of best practice: better valorization 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.
