Baden-Württemberg will not be able to meet its future demand for hydrogen and its derivatives from domestic production alone. The Fraunhofer Institute for Solar Energy Systems ISE has therefore investigated how Baden-Württemberg can be supplied by imports in the future. The researchers analyzed how and at what cost hydrogen and its derivatives methanol and am-monia can be imported via pipelines and waterways. Production in Germany was also considered for comparison purposes. European pipeline transportation is therefore the most cost-effective option. The study was funded by the Baden-Württemberg Ministry for the Environment, Climate Protection and the Energy Sector.

Proton exchange membranes (PEM) are one of the most promising technologies for the production of green hydrogen by electrolysis. To reduce the material and manufacturing costs for PEM electrolyzers, the Fraunhofer Institute for Solar Energy Systems ISE is researching scalable production processes. Now, for the first time, it has succeeded in producing ultra-fine porous transport layers made of titanium using a screen printing process, thereby reducing the cost of catalyst materials. Industry-standard, scalable equipment was used. At the Hannover Messe (March 31 to April 4, Hall 13, C41), the institute will present samples of the optimized microporous transport layer, along with other innovations.

The Fraunhofer Institute for Solar Energy Systems ISE and the University of Auckland in New Zealand have signed an agreement to collaborate on AI-based data analysis. The two research institutes want to establish a long-term cooperation that brings together their complementary expertise. Important fields of application are the quality assurance of battery cells and intelligent battery production. Initial exchanges and the joint supervision of students have already begun.

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.
