A new CEN-CENELEC Workshop is being planned which will complement the activities of the EU Research project HYSTORE (Hybrid Services from Advanced Thermal Energy Storage Systems). The mission of this project is to develop and validate an innovative set of Thermal Energy Storage (TES) concepts, based on the combination of cutting-edge technology components, unlocking the potential of this kind of energy storage as a sustainable solution.
The development of Thermal Energy Storage (TES) systems is playing an increasingly important role in the transition towards a more sustainable energy production for Europe. Various technologies are utilized in TES, such as ALL-IN-ONE Phase Change Material (PCM) solution, LOW-TEMP PCM HEATING&COOLING solution, PCM HEATING solution and Thermochemical Material (TCM) HEATING&COOLING solution. Connecting these technologies to the grid can transform them from being supplementary to key assets in centralized energy generation.
This Workshop will focus on the semantic modelling and standardization of TES systems to improve their integration and performance within modern energy ecosystems. This includes developing a comprehensive ontology for TES that defines key attributes (e.g., capacity, thermal properties, operational modes) and supports use cases such as renewable energy integration, demand-side management, and smart grid services. Physical engineering, design and economic or policy frameworks are outside of the scope. Rather, the focus remains on semantic interoperability, data standardization, and TES integration within broader energy management systems.
The initiative aims to strengthen the efforts of standardization and ensure that the knowledge gained from HYSTORE can be widely adopted. The planned outcome is the development of two CEN Workshop Agreements (CWAs):
- SAREF4TESS Ontology Specification: focussed on defining a standardized semantic framework for modelling, integrating, and optimizing TES systems within energy management ecosystems
- SAREF4TESS Validation Report based on use case demonstrations: focused on evaluating the application, scalability, and interoperability of the SAREF4TESS ontology across four pilot use cases
The kick-off meeting for the Workshop will be a hybrid meeting and is planned to take place at the University College Dublin as well as remotely via Zoom on 6th June 2025 from 10.00 a.m. to 12.30 p.m. (CEST). To register to attend in person, please contact the Workshop Secretary Fernando Utrilla Ortega (FUTRILLA@une.org). To register to attend remotely, please use this registration link.
All interested parties are invited to submit comments on the draft Project Plan using the commenting form below, to the Workshop Secretary (UNE) Fernando Utrilla Ortega (FUTRILLA@une.org) by April 30th, 2025.
