Photovoltaic systems are constantly exposed to environmental factors during operation. Dust, pollen, agricultural emissions, or other deposits on the module surfaces lead to so-called soiling effects and can significantly reduce the energy output of PV systems. At the same time, regular cleaning and manual inspections are time-consuming and not always economically viable. In the collaborative project “PV-SoilSens,” the project partners plan to develop an energy-self-sufficient and self-regenerating soiling sensor.

Mitteldeutschland entwickelt sich zu einem wichtigen Standort der Wasserstoffwirtschaft. Der Erfolg hängt jedoch stark von qualifizierten Fachkräften ab. Um das vorhandene Potenzial für grünen Wasserstoff auszuschöpfen, braucht es gezielte Weiterbildung, neue Lernformate und eine enge Zusammenarbeit zwischen Wissenschaft, Wirtschaft und Gesellschaft.

PFAS are used in hydrogen technologies but pose significant environmental and health risks. The UPeM project is developing standardized methods to measure and assess the release of these substances—laying the groundwork for safe applications in fuel cells and electrolysis.

Electrolysis is a key component of the future hydrogen economy. Low production costs for hydrogen are a prerequisite for market penetration and rapid transformation. The manufacturing costs for electrolysers and their operating costs are key cost drivers. Bubble-free electrolysis promises to reduce energy consumption by up to 15% compared to proton exchange membrane (PEM) electrolysis.

South Africa could play an important role in the coming years as a secure producer of green hydrogen, including as a supplier to Germany. However, there are currently challenges in storing and distributing the raw material. This is where the recently launched Fraunhofer joint project “HySecunda” comes in, in which nine Fraunhofer Institutes and the Fraunhofer Academy are collaborating. The project aims to find optimized solutions for the production, storage, and certification of green hydrogen. The consortium also supports capacity building in the region and in current projects on hydrogen-based fuels for aviation.

The Mon-KI project addressed current development issues relating to increasing the efficiency of photovoltaic (PV) systems. The focus here was on reducing the effort required for regular operation and automated fault detection in large PV systems. The main objective of the project was to develop and implement a largely automated, AI-based monitoring system for PV systems with a view to ensuring reliable operation, timely identification of faults, and estimation and prediction of yields and maintenance work.

The main objective of the project in Module 2 of the funding guideline (FRL) for “International Hydrogen Projects” is to establish the technical, scientific, legal, and commercial foundations for scaling up the “HyDSerbia” pilot project at various locations in the Republic of Serbia by implementing a large-scale, practice-oriented feasibility study and further developing a technical and economic simulation tool for energy systems.

Green hydrogen is seen as a key to the energy transition and sustainable storage of renewable energy. So far, hydrogen production by electrolysis is still expensive, mainly due to costly precious metal catalysts and complex manufacturing processes. The HOLMES-AEM project aims to make green hydrogen production more affordable and sustainable. To achieve this, the project focuses on developing innovative catalysts that do not require expensive precious metals.

Offshore wind turbines generate significantly more electricity than their land-based counterparts, and do so more regularly. The H2Mare hydrogen flagship project aims to harness this potential by using renewable electricity directly at sea to produce hydrogen and hydrogen-based products. The future partners plan to integrate the water electrolyzer directly into a wind turbine, thereby providing innovative technologies for producing green hydrogen offshore.

The primary goal of the H2Giga - STacIE research project is to industrialize the production of electrolyzer stacks at the cell component and stack levels. This will be achieved through an industrializable, product-oriented concept, improvements in the technical and economic properties of the cell components, and the development of industrial production processes. Key research steps include the identification, evaluation, and further development of new materials and material combinations, as well as the necessary production processes.
