Characterization by scientific analysis of the material composition and the mechanical and electrical performance of interconnects is key for understanding interconnection processes. With this in-depth knowledge, interconnection processes can be optimized to improve the performance and long-term stability of joints of solar and battery cells.

Climate protection and energy security are moving more and more into the center of societal awareness and behavior. The ‘net-zero emissions’ targets by mid-century, which are ratified or under discussion by nearly 200 countries define a paradigm shift towards the limitation of the global temperature. Hydro-gen and its derivatives will be the backbone of a sustainable global energy trading system since it can store vast amounts of energy over long periods of time, can be transported in ships or pipelines and can be used in all energy consuming sectors as a replacement of fossil-based energy carriers. Furthermore, hydrogen is the basic molecule used in generating renewable synthetic fuels or chemicals. Linking the energy economy with the zero-emission mobility, vehicles powered by hydrogen in fuel cells or by synthetic fuels offer attractive filling times and driving ranges along with a known infrastructure and refueling system, familiar to that of fossil fuels.

For a secure and reliable power supply based on 100% renewable energy sources, decentralized and centralized stationary battery storage systems are needed on a large scale. A key task of these storage systems is to keep the power grid stable and fail-safe in the face of fluctuating feed-in from photovoltaics (PV) and wind. They also provide surplus electricity storage for demand-optimized use at a later time.

Power to Liquids (PtL) denotes the conversion of sustainable hydrogen and COx/N2 to energy carriers such as methanol and ammonia, which can also serve as platform molecules for the chemical industry or as clean fuels reducing CO2 and local emissions such as soot/NOx. PtL contributes to decarbonization of all energy economy sectors.

The efficient and economically viable utilization of green hydrogen in various sectors requires a comprehensive understanding of all individual elements in the hydrogen supply chain. In our techno-economic analyses, we develop and evaluate tailor-made solutions for the production of clean hydrogen from renewable energy, its efficient storage and demand-oriented distribution

Sustainably produced hydrogen derivatives will play a major role as future energy carriers, as they can be transported and stored in existing infrastructure. New and efficient conversion via catalytic reforming processes will be decisive in spreading their utilization in all sectors.

The innovative High Temperature Near-Ambient Pressure X-Ray Photoelectron Spectroscopy (HT-NAP-XPS) brings conventional XPS to a new dimension of surface science. Functionalized surfaces can be investigated at pressures up to 25 mbar and temperatures up to 1 000 °C allowing in situ studies of reaction mechanisms and their intermediate stages – especially attractive for materials used in hydrogen technologies

Electrolyzers cleanly and efficiently split water electrochemically to generate hydrogen and oxygen. In particular, proton exchange membrane (PEM) electrolysis is well-suited to produce green hydrogen from renewable energy sources, with good efficiency at high current densities and dynamic operation at high pressures within a broad operating range

Für eine sichere und zuverlässige Stromversorgung, basierend auf 100% erneuerbaren Energien, sind dezentrale und zentrale stationäre Batteriespeicher in großem Umfang notwendig. Eine wesentliche Aufgabe dieser Speicher ist, das Stromnetz angesichts fluktuierender Einspeisung von Photovoltaik (PV) und Wind, stabil und ausfallsicher zu halten. Zudem speichern sie überschüssigen Strom ein und stellen ihn bedarfsgerecht zu einem späteren Zeitpunkt zur Verfügung.
