From 24-25 October 2024, the SUSHEAT project consortium gathered in Stockholm for its 3rd General Assembly meeting, hosted by Sweden’s KTH Royal Institute of Technology. This two-day event marked an important milestone for the project, bringing together partners from across Europe to review key accomplishments, discuss ongoing challenges, and outline strategic goals for the next project phase.
Chaired by the project coordinator, UNED, the meeting reviewed the progress achieved in decarbonizing industrial heat. Over the past 18 months, the SUSHEAT project has made significant advancements in developing sustainable solutions to capture, recover, and reuse industrial waste heat, boosting energy efficiency across a range of sectors.

Key SUSHEAT achievements in the first 18 months of the project
- Thermal Energy Storage (TES): Developed an innovative design for the TES tank, completed lab-scale experimental evaluations, and reached a significant milestone in advancing efficient energy storage solutions within the SUSHEAT project.
- Final Phase Change Material (PCM) Selection for TES: Selected and characterized optimal PCMs for system experimental testing, ensuring thermal efficiency and reliability in the storage system.
- Heat Demand and Requirements Analysis: Conducted a comprehensive analysis of heat demand, requirements, and associated challenges across secondary end-users and four additional industries.
- Laboratory Rig Design and Validation Strategy: Defined the preliminary design and operational framework for the SUSHEAT prototype laboratory rig, ensuring its replicability across case study applications.
- Digital Twin Development: Completed specification, modeling, and simulation of integrated digital systems, processes, and interdependencies, establishing a robust foundation for advanced digital control and data management.
- Preliminary SUSHEAT Optimization: Analyzed various energy sources—waste, ambient, and solar—available in target industries and defined optimal operating modes to enhance system efficiency and adaptability.
- Project Results Dissemination: The project partners, led by RTDS Association as dissemination and communication lead, have successfully disseminated their research findings through OpenScience platforms, expanding the visibility of the SUSHEAT project’s contributions to the field.
