In October 2021, the EU HORIZON 2020 Project RESTORE – Renewable Energy based seasonal Storage Technology in Order to Raise Economic and environmental sustainability of DHC – started working.

The main objective of the RESTORE project is to develop a solution that allows integrating a wide variety of Renewable Energy Sources (RES) in District Heating and Cooling (DHC) networks with high supply shares. This is done with an approach based on two key innovative technologies: Reversible Organic Rankine Cycle (rORC) combined with Thermo-Chemical Energy Storage (TCES).

The innovative combination of rORC and TCES technologies makes it possible to overcome the differences between the availability of heat from RES or waste excess heat and the fluctuating demand for heat or cold in present DHC networks, thus increasing the availability and reliability of energy distribution in supply networks. In summary the RESTORE project provides a clear break-through thermal energy storage technology for the decarbonisation of the district heating sector, enabling the use of RES and waste excess heat collected in summer for heating purposes in winter in a very competitive way.

The RESTORE project addresses the heating and cooling sector, which is the sector representing the highest potential for the use of RES and waste heat integration due to fast and cost-effective transformation processes. The project started in October 2021 and has a duration of 4 years.
