From September 23rd to 25th, 2024, the city of Stuttgart, Germany, hosted the 4th International Workshop on Carnot Batteries. The event brought together energy storage experts, with a particular focus on thermal energy storage, to discuss the latest research and demonstration of Carnot Batteries.

The two-day lecture program provided a comprehensive overview of innovative research approaches, covering various Carnot battery concepts, their demonstration, and the integration of these technologies into the power grid and sector coupling. Speakers from both academia and industry participated, making this workshop an important international platform for the presentation and visibility of the latest research results on Carnot Batteries.

Radia AIT EL CADI and Tiago Eusébio, researchers from the University of Évora, were present at the event. Tiago shared his experience: “We had the chance to attend the 4th edition of the International Workshop on Carnot Batteries in Stuttgart and witness the scientific and technological evolution of this relatively new, flexible, and potential low-cost electricity storage concept. The event covered a wide range of topics related to Carnot battery concepts, their demonstration, integration into the power grid, and sector coupling. It was a great opportunity to discuss in person with several key players and stay up to date with the most recent developments in this field.”

Radia added: “At the 4th international workshop on Carnot batteries, various key topics were addressed, ranging from the current state-of-the-art to innovations in the field. Discussions covered storage materials, system designs, demonstrations, as well as materials and components involved in Carnot battery systems. Life cycle analysis and cost analysis were also explored in depth. It was particularly insightful to see numerous European projects working on developing the Carnot battery concept, aimed at both grid integration and industrial cooperation. Some of the innovative approaches included advancements in heat pumps and thermodynamic cycles, which further highlight the potential of these systems”. 

The workshop has established itself as a meeting point for scientists and industry professionals, fostering collaborations and advancing knowledge on energy storage technologies, which are crucial for the global energy transition.
