ZBT, together with its partners, is working on technical solutions for our future energy system. In addition to comprehensive basic research in collaboration with scientific partners, various projects in applied research and experimental development are carried out in cooperation with industry and science. Exclusive contract research as well as various services complete the portfolio of ZBT. CHANGES, CHALLENGES, CHANCES. One of the greatest challenges for mankind is the global transformation of the energy system in compliance with the Paris agreement on climate change. The energy system, still largely based on fossil fuels, must be converted over the next three decades into a sustainable, carbon-neutral system with nearly 100% renewable energy. Hydrogen plays a key role as seasonal energy storage, as fuel for the three sectors electricity, heat and transport, and also as reactant in the chemical industry. As an application-oriented institute, ZBT develops future technologies in the three main topics hydrogen, fuel cells and batteries. HYDROGEN - Electrolysis - Infrastructure and Quality - Chemical fuels - Reforming - Standardization FUEL CELLS - Membrane-electrode assembly - Bipolar plates and gaskets - Stack technologies - Fuel cell systems BATTERIES - Lithium-ion batteries - Lithium-sulfur batteries - Redox-flow batteries
