Efficient technologies are the key to a successful energy transition
The de-fossilisation of society and the economy requires a consistent transition towards the integration of renewable energy technologies. However, this can only succeed by developing innovative technologies for energy generation, conversion and storage that are even more efficient, cost-effective and environmentally friendly. Digitalization is supporting this transition by making it possible to intelligently network complex systems, such as producer networks, energy grids or industrial and private energy consumers.
From photovoltaics to batteries to hydrogen - Fraunhofer IST develops innovative solutions for the energy sector
At Fraunhofer Institute for Surface Engineering and Thin Films IST, we actively collaborate in order to advance energy research in a wide range of areas. Our main focus is on the development of innovative and sustainable battery technologies based on solid electrolytes (All-Solid-State Batteries - ASSB) and recyclable raw materials. In addition to battery production, we also focus on the development of efficient recycling techniques in order to close the material loop.
In the field of photovoltaics, we ensure ever greater efficiency of solar cells with the development of functional coatings and s layer systems produced by means of new and industrially established processes. We are also involved in developing hydrogen technologies that are market-ready by optimizing coating systems for components such as electrolysers, fuel cells or hydrogen tanks.
Furthermore, we solve systemic problems such as industrial hydrogen supply and the implementation of sector coupling. Together with strong partners from industry and science; the Fraunhofer Center for Energy Storage and Systems ZESS, the Battery LabFactory Braunschweig (BLB), the Hydrogen Campus Salzgitter and the Open Hybrid LabFactory (OHLF), we drive energy research forward.
Jointly we find solutions and we would be happy to advise you!
Our main focuses and expertise
Sustainable energy storage systems and converters
In the transition from fossil fuels to renewable energies, a holistic view of the entire product life cycle of components for hydrogen and battery applications is crucial; this will enable the effective and resource-conserving storage of energy from renewable sources and the promotion of a green energy economy. In addition, high production costs and the lack of infrastructure are major hurdles standing in the way of widespread market acceptance. At the Fraunhofer IST, we pursue the goal of realizing technologies economically and ecologically. In order to achieve this, we are developing innovative approaches for the production, utilization and recycling of energy storage systems and converters.
The future of solar-cell production
Although photovoltaics is now the most affordable technology for the generation of electricity, there are still major hurdles to overcome. One of the key issues is insufficient grid integration and limited storage options. This situation makes it impossible to feed all of the created electricity into the grid, and the resulting increased grid fees have to be borne by the consumers. A further problem lies in the production chain: PV modules are predominantly manufactured in China. In order to strengthen Europe’s resilience in this field, independent European module production is necessary. The associated higher costs would only have a minor impact on electricity generation costs – less than 0.5 Cent per kilowatt hour.
