Integration of thermal energy storage in industrial processes: challenges and opportunities

The transition to sustainable energy systems is crucial in reducing greenhouse gas emissions and increasing energy efficiency. This paper synthesizes insights from industrial experts and academic researchers on the challenges, opportunities and solutions of integration of thermal energy storage (TES) in industrial energy systems. These insights were gathered during an international expert workshop on TES, organized by the European Energy Research Alliance as part of the Joint Program on Energy Efficiency in Industry (EERA-JP EEIP) on November 7th, 2023, discussing a white paper on industrial thermal energy storage. This paper provides a comprehensive overview of the current state and future potential of TES technologies. Demonstrating technology benefits, continuing material development, improving economic feasibility, enhancing system flexibility, developing innovative business models, fostering policy supports, and facilitating knowledge transfer are believed to be essential for the successful adoption of TES technologies in industry.
