HYSTORE aims to develop and validate innovative Thermal Energy Storage (TES) concepts based on advanced Phase Change Materials (PCM) and Thermochemical Materials (TCM) solutions. The new concepts address multiple applications in heating and cooling (H/C) systems and domestic hot water (DHW) configurations. In addition, the project establishes optimal conditions for delivering hybrid energy and power services, supported by the development of a smart aggregator and an open-source multi-service platform.
HYSTORE promotes the deployment of thermal storage technologies to increase the share of renewable energy sources (RES). It positions TES as a key enabler for enhancing the flexible and reliable operation of building-level electrical and thermal systems as decentralised energy resources. This approach maximises the utilisation of locally generated renewables while supporting grid peak shaving and demand-side management in increasingly renewable-driven energy systems.
Overall Objectives
-
Deploy plug-and-play TES solutions for daily and monthly storage, seamlessly integrated with building energy systems and both electricity and thermal networks.
-
Remove technical barriers associated with installation complexity and operational challenges by addressing engineering design, technical training, and interoperability with other smart devices.
-
Reduce the Levelised Cost of Energy (LCOE) associated with thermal storage, making TES competitive with widely adopted Electrical Energy Storage (EES) solutions and aligned with the objectives of the SET Plan.
-
Operate TES solutions as demand-side management assets capable of autonomous peak load reduction, releasing grid capacity and creating optimal conditions for flexibility markets and frequency regulation, while developing business and operational models for Capacity-as-a-Service.
-
Validate the proposed TES solutions and the open-source operational platform at TRL 6/7 across multiple demonstration sites:
- Residential / mixed-use buildings in a continental climate (Austria)
- Residential building in a Nordic climate
- Multifunctional building in a Mediterranean climate (Spain)Building complex connected to district networks in a cold climate (Ireland)
