The high performance center Green Materials for Hydrogen (GreenMat4H2), managed by Fraunhofer IWKS and Fraunhofer LBF, develops technologies for the safe production, storage, transport, and use of hydrogen. With a network of partners from industry, science, and the public sector, research results are transferred to industrial applications. Our service to the hydrogen economy includes the development of green, sustainable materials and processes, the safe operational stability and reliability of assemblies and systems, as well as the efficient recycling of components and materials.
