Green Electrochemical Energy Storages - GrEEn

The clustered research project „GrEEn” (Green Electrochemical Energy Storages) is an interdisciplinary research program across several locations which aims to develop the basis for future mobile and stationary electrochemical energy storage systems in coordinated sub-projects. The focus is on lithium-ion, lithium-sulfur and redox-flow batteries which operate using mostly organic-biological resources as active and inactive materials which are produced ecoconsciously. Additionally, economic and ecologic aspects are also regarded with respect to environmental compatibility and recyclability. This approach within the “GrEEn” project helps to transition these key technologies into the future.

Batteries play a crucial role in the transformation of the energy sector (Energiewende). They enable vehicles to be powered by electric current instead of fossil fuels, and they could compensate for the fluctuating availability of renewable energy. However, conventional battery manufacturing processes often require excessive amounts of energy and raw materials. This is mainly because the mining and processing of many materials and components used in batteries are harmful to the environment. “This is where we come in. Over the next three years, we will investigate sustainable material, process, and systems concepts for electrochemical storage. A pioneering task for material scientists,” according to Prof. Martin Winter, scientific head of the WWU MEET Battery Research Center and founding director of the Helmholtz Institute Münster (HI MS, Institute of Energy and Climate Research 12/IEK-12 at Forschungszentrum Jülich).

The project also takes into account a sustainable life cycle of the “green” battery. In addition to material development, the recyclability and possibility of implementing environmentally friendly battery systems on an industrial scale will also be evaluated. “In addition to economic conditions, the future potential of renewable energy is particularly dependent on innovations. By placing a focus on non-hazardous substances, the project (…) is providing an important stimulus,” said minister Pinkwart, underlining the significance of the research approach upon presenting the research project with its grant notification in autumn.
