How does a TMS battery work? This question can now be answered very clearly and vividly. Dobrila Grujikj, a student from the "Ss. Cyril and Methodius University" in Skopje (North Macedonia), created a computer animation on the TMS battery as part of her three-month IAESTE internship at the IPM.
Dobrila Grujikj is studying at the Faculty of Computer Science and Engineering and has already gained some practical experience in creating computer animations during her studies, which she has now been able to build on.
Under the guidance of Thomas Schäfer, she first looked at how the TMS battery works and considered which simplifications were necessary to make the functionality easy to understand in an animation. She also received important support from Steffen Härtelt, a technician at the THERESA test facility.
She then created a corresponding storyboard and carried out the modeling of the main components of the TMS battery system, including the TMS combination machine. Then all the settings for the animation of the scenes, the lighting and the camera setup were made before the animation was rendered. Finally, the animation was provided with explanations and finalized. The result is impressive! The animation can be found on the TMS project website.
On December 21, the colleagues at IPM bid farewell to Dobrila Grujikj and honored her work.
The development of a concept for the realization of the TMS battery began at the IPM around 3 years ago. The TMS battery is a thermo-mechanical energy storage system (TMS) and is based on the many years of experience of the scientists working at the IPM. Their expertise in the application of thermodynamic processes and their technological implementation is particularly evident here.
After initial ideas from the scientists, the concept for the implementation of a highly flexible thermal battery for the energy transition matured. These batteries are also known as CARNOT batteries. The concept was further developed and perfected together with Spilling Technologies GmbH, a company based in Hamburg for more than 130 years.
The unique development of the TMS battery received international attention as part of the iea Energy Storage Task 36 - Carnot Batteries, in which IPM research employees Thomas Schäfer and Sebastian Braun are actively involved.
The special feature of the TMS battery, compared to other systems, is the much simpler but effective implementation of CO2-free electricity storage. The core of the system is the unique, multi-stage TMS combination machine, which can work very effectively both as a vapor compressor and as a vapor expander.
The TMS battery conserves raw material resources, as it requires almost exclusively classic, fully recyclable raw and operating materials, such as steel and water, and also considerably simplifies the operating modes of a CARNOT battery! In contrast to conventional systems, the TMS battery only requires a high-pressure steam accumulator and a low-pressure steam accumulator. Both are coupled by the newly developed TMS combination machine.
The electrical energy can be stored and withdrawn very flexibly. In addition, the TMS battery is able to store available surplus thermal energy and release it as electricity or heat when required. This makes the TMS battery suitable for coupling different energy sectors and thus makes an important contribution to the energy transition.
