RESTORE – Renewable Energy based seasonal Storage Technology in Order to Raise Economic and environmental sustainability of DHC – is a HORIZON 2020 project financed under the SOCIETAL CHALLENGES – Secure, clean and efficient energy programme.

The main objective of the RESTORE project is to develop a solution, based on the combination of two key innovative technologies, that allows integrating a wide variety of Renewable Energy Sources (RES) in District Heating and Cooling (DHC) networks.

RESTORE provides efficient and innovative solutions for the decarbonisation of the heating and cooling needs, using an optimal integration of different renewable energies via an innovative thermochemical energy storage (TCES) combined with a heat pump (HP) and an Organic Rankine Cycle (ORC), paving the way towards the renewable-driven DHC transition and having a direct environmental impact on GHG emission, air pollutants and fossil fuel reduction.

The innovative combination of a TCES and the HP/ORC technology makes it possible to overcome the intermittency among the supply of thermal energy and the fluctuating demand for heat or cold present in DHC networks, thus increasing the availability and reliability of energy distribution on the grid.

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, especially solar heat, and waste excess heat collected in summer for heating purposes in winter in a very competitive way.

The RESTORE project involves 12 partners spread over 7 different countries in the EU. CENER, with large experience in the renewable and energy storage fields and in coordinating H2020 projects, leads the consortium, which encompasses an interdisciplinary group of entities. Universities with long experience in the concepts proposed assist companies specialized in the industrialization of the developed technology. SME specialized in simulation tools ensure the reliability of virtual use cases analysis supported by industrial companies with large experience in sector coupling in DHC networks. Moreover, the consortium involves experienced entities, which carry out the assessment of the proposed technology in various areas as well as the dissemination and the exploitation of the project results.
