In the future, charging stations along freeways, in parking lots or at logistics centers will have to deliver much more power in a short space of time than they do today. For this reason, new charging stations can no longer simply be connected to the low voltage power grid. In the project "MS-Tankstelle", Fraunhofer ISE and partners from industry therefore developed the medium voltage system technology for fast charging stations that will enable peak loads of several megawatts in the future. The technology, which uses efficient silicon carbide semiconductors and higher voltages, leads to lower material use and lower costs for fast charging stations. At the same time, the system is very efficient and can be flexibly applied to charging stations of different sizes and different vehicle types. A demonstrator of one charging point can be viewed at the Fraunhofer Energy Alliance booth at the E-World from 11-13 February in Essen, Germany (hall 5, D 126).

The 5th International Conference on Electrolysis ICE 2025 will be held in Freiburg, Germany, from August 25 to 29, 2025. This event provides a key platform for technical experts in industry, academic researchers and PhD students, for example, to share breakthroughs in water electrolysis, particularly in its role as a technology for green hydrogen production. The organizing committee has already launched the Call for Papers, which remains open until end of January 2025.

In Germany, net public electricity generation from renewable energy sources reached a record share of 62.7 percent in 2024. Solar power generation reached a new record of 72.2 terawatt hours in 2024, and the expansion of photovoltaics continued to exceed the federal government's targets. As the share of electricity generation from lignite (-8.4%) and hard coal (-27.6%) continued to fall sharply, the carbon dioxide emissions in the German electricity mix were lower than ever before. The balance of imported electricity rose to 24.9 terawatt hours. These figures are the results of an analysis presented by the Fraunhofer Institute for Solar Energy Systems ISE. The analysis is based on the data available on the platform energy-charts.info.

Fraunhofer ISE and Fraunhofer UMSICHT have developed a prefabricated façade element with integrated photovoltaics for buildings that combines power generation, weather protection and thermal insulation. By eliminating the need for an additional substructure for the solar modules, this element can save large amounts of building materials, while speeding up installation during retrofits at the same time. Visitors to the BAU, the world's leading trade show held in Munich from January 13 to 17, 2025, can view two variants of the BIPV façade elements at the Fraunhofer Building Innovation Alliance's stand. The façade element was developed as part of the Fraunhofer flagship project "BAU-DNS".

Artificial Intelligence (AI) helps heat pumps to operate more efficiently, by avoiding incorrect device settings and optimizing system operation. The Fraunhofer Institute for Solar Energy Systems ISE is researching a new generation of smart heat pumps that use artificial neural networks to adapt to environmental conditions and to learn as conditions change. This increases both the energy efficiency and user comfort. Extensive simulations showed promising potential energy savings from 5 to 13 percent in addition to increased comfort. These results have been confirmed by measurements in an initial field test in a real building.
