New project in Homburg: Battery storage for the energy transition!
Saarland University is launching the “MuBatt” project to develop innovative battery storage strategies for the energy transition.
New project in Homburg: Battery storage for the energy transition!
The innovative project “MuBatt – Multi-Use Operation of Stationary Battery Storage Systems” will start at Saarland University on October 2, 2025. The main goal of this initiative is to develop new strategies for the flexible, efficient and economical use of battery storage. The project is funded with around 310,000 euros by the Ministry of Economics, Innovation, Digital and Energy, using funds from the European Regional Development Fund (ERDF) and corresponding state funds.
A central element of the project is the focus on the multi-use operation of stationary battery storage systems, which are used for various tasks. This includes grid stabilization, self-consumption optimization and load shifting. These measures are intended to make a significant contribution to the energy transition and climate protection by promoting the integration of renewable energies.
Practical development and application relevance
A special aspect of the project is the practical development. The concepts are tested and validated on a real storage system in Homburg. The results of the project are intended to benefit municipalities as well as network operators and companies. Economics Minister Jürgen Barke highlights the need for intelligence in the energy system and explains that innovative approaches are crucial for a sustainable future. University President Prof. Ludger Santen points out that battery storage plays a central role in implementing the energy transition.
Prof. Georg Frey, the project leader, emphasizes the importance of financial support for expanding expertise and the applicability of the results achieved. These are not only of interest to local actors, but also have the potential to generate supra-regional effects.
Battery storage in Germany: market development and segments
Germany is expected to continue to play a significant role in the field of battery storage systems (BESS) in 2025. This is due to strong political support, incentives such as network fee exemptions and increasing interest from investors. The market segments in the field of battery storage systems can be broken down as follows:
| Market segment | capacity | New investments in 2023 | Growth rate 2023-2032 |
| Home storage | ≤ 30 kWh | approx. 85% | 0.2% |
| Industrial storage | 30-1,000 kWh | 6% | 9% |
| Large storage | ≥ 1,000 kWh | 8% | 31% |
The home storage sector in particular continues to be strong, with a predicted average annual growth rate of just 0.2% until 2032. The cost savings through the combination with solar systems and government subsidies such as the KfW 270 loan program are driving this sector forward.
In the industrial sector, storage with a capacity of 30 to 1,000 kWh accounts for 6% of newly installed capacities and is expected to grow by 9% annually. Cost savings and energy independence are particularly crucial factors here. The large storage market, on the other hand, with a capacity of over 1,000 kWh, shows more significant growth with a forecast rate of 31%, reflecting the trend towards grid stability and the integration of renewable energy.
This dynamic development in the field of battery storage will not only become an important part of the energy transition in Germany, but also a decisive factor for the European energy industry as a whole.
