How can municipalities better align fluctuating renewable energy yields, heating demand, and local energy production? In the joint research project “biovolatil,” the project partners are developing and testing technical solutions to operate biomass gasifiers with combined heat and power plants in a demand-responsive manner and to integrate them with geothermal energy and existing municipal energy systems. A newly developed reactor insert has already been in operation for approximately 3,000 operating hours. Initial tests on product gas recirculation also demonstrate how the operating range can be expanded.

How can fuel cell systems for maritime applications and specialized land vehicles be supplied with hydrogen without having to carry it in separate tanks? At Hydrogen Technology World Expo, taking place October 20–22, 2026, in Hamburg, Germany, the Fraunhofer Institute for Microengineering and Microsystems IMM will present a diesel reformer and demonstrate how diesel fuel can be converted into a hydrogen-containing gas directly at the point of use for power generation.

Heat pumps are an efficient and future-proof key technology for the energy transition in heating systems and for achieving Germany’s climate goals. In the WESPE project, Fraunhofer researchers and their partners are working to make heat pump installation faster, more productive and more efficient to support the transformation of the heating sector, despite a shortage of skilled workers. Innovative, standardized digital tools and practical installation solutions tested in real-world conditions are to significantly speed up future heat pump retrofits.

What would happen to the price of electricity if significantly more battery storage systems were traded on the market? The Fraunhofer Institute for Solar Energy Systems ISE is releasing a price simulator today on its Energy-Charts.info platform that answers this question using real market data. The tool uses the actual buy and sell bids from the daily electricity exchange auction and adds a freely selectable number of battery storage units. For each quarter-hour, users can see how the exchange electricity price would have changed, how the batteries charge and discharge, and what their charge levels are. The freely accessible simulator is updated daily with the latest electricity trading results.

Seawater and brackish water could serve as alternative water sources for hydrogen production. The challenge is that conventional electrolyzers require high-purity water that needs extensive treatment. In the SeaEly project, the Fraunhofer Institute for Wind Energy Systems IWES and the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM investigated how suitable seawater and brackish water are for hydrogen production and what testing and evaluation infrastructure is needed.

With the construction of a new prototyping centre, the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Dresden is expanding its research infrastructure in the field of hydrogen technologies. The new building, situated within the Fraunhofer Institute Centre Dresden, will in future provide the facilities needed to manufacture, further develop and test electrodes for alkaline water electrolysis (AEL/AEM) on an industrially relevant scale under conditions close to real-world applications. The build-ing is scheduled for completion in summer 2028.

A new technical report by Fraunhofer ISI and the International Council on Clean Transportation (ICCT) provides a detailed picture of where and when charging demand for battery electric trucks is likely to arise across Europe through 2045. Using the newly developed VESUVIO model, the researchers show that charging demand will grow strongly in the coming decades, remain highly concentrated in a limited number of locations, and differ substantially across countries.

Researchers at Fraunhofer ISE have developed a prototype of a manufacturer-neutral app for heating, ventilation, air conditioning and plumbing contractors that enables the virtual planning of heating systems. Unlike software tools already available, the “Heat Pump PlanAR” app combines various steps of the planning and installation process into a single application. The software prototype is the result of the “WESPE” collaborative project led by the Zentralverband Sanitär Heizung Klima (Central Asso-ciation for Plumbing, Heating, and Air Conditioning) ZVSHK and was designed in close collaboration with trades businesses. The application is now set to be further developed in collaboration with interested software companies and brought to market.

In its annual study for Interzero, Fraunhofer UMSICHT examined how circular economy practices can help protect the climate and conserve resources: Compared to primary production, 900,000 metric tons of greenhouse gases and 7.2 million metric tons of resources were saved in 2025. A particular focus this year was on plastics recycling.

Since 1986, the calibration laboratory at the Fraunhofer Institute for Solar Energy Systems ISE has been measuring solar cells, and since 1991, photo-voltaic (PV) modules as well. Over the course of its forty-year history, it has calibrated the performance of thousands of solar cells and modules using a wide variety of technologies. To date, the “CalLab” has confirmed 152 record results. Sixty-six of these records were for PV modules—primarily silicon modules—while 86 referred to solar cells. The first record was set in 1992 by a mini silicon solar module with an efficiency of 16.4 percent, submitted by Deutsche Aerospace Aktiengesellschaft and featuring Bayer silicon wafers. The most recent record measured by CalLab confirmed that a module from AZUR SPACE, temicon and Fraunhofer ISE, with an efficiency of 34.4 percent, is currently the world’s most efficient solar module.
