Schleswig-Holstein: Focus on innovations for the green energy transition!
The CAU Kiel and Fraunhofer ISIT promote innovative microelectronics projects for the energy transition and sustainable power supply.
Schleswig-Holstein: Focus on innovations for the green energy transition!
The collaboration between Fraunhofer ISIT and the Technical Faculty of the CAU in Kiel marks a significant step in the development of technologies for the energy transition. This collaboration focuses on microelectronics, power electronics and innovative energy storage systems. The aim is to optimize components for the future challenges of a modern power grid and the integration of renewable energies.
Marco Liserre and Fabian Lofink lead Fraunhofer ISIT, which is characterized by its expertise in efficient energy conversion and MEMS technologies. Liserre focuses on a sustainable energy supply, while Lofink advances high-precision sensors and actuators. These skills are essential to realize applications in various areas such as medical technology, the automotive industry and industrial automation.
Innovation through cooperation
The “Super-HEART” project is a central element of this cooperation. It is funded with 2.5 million euros from the EU until 2025 and aims to develop sustainable power converters for data centers. In addition to ISIT and CAU, partners in this project are Trinity College Dublin. One focus is on cost-efficient, renewable power supply that uses hydrogen and solar energy.
The discussion of current and future projects takes place as part of the ISIT@CAU workshop. The KiNSIS project is also presented here, which networks over 130 scientists from the natural, engineering and life sciences. These research approaches gain a stable basis through funding and industrial contracts, especially in the area of electronic energy systems.
The role of energy storage
Energy storage plays a crucial role in sustainable energy supply. Compressed air storage, which mechanically stores energy using compressed air, is characterized by an acceptable energy density of 1-2 kWh/m³. They can be implemented in different forms, such as compressed air tanks or caverns in salt domes. These technologies are particularly relevant as they help offset the volatility of renewable energy.
When using compressed air, compressing the air is crucial to ensure efficient storage. However, high temperatures generated during compression pose a challenge. These must be controlled using appropriate processes to minimize heat losses and increase the efficiency of energy storage.
The efforts of both institutions in Kiel are an outstanding example of how science and applied research work together to develop technological solutions for the energy transition and promote sustainability in the energy sector. This means that Schleswig-Holstein is well positioned to take on a pioneering role in the energy transition.
