The goal of the Energy and Conversion Lab is to map the four levels for sector-coupled energy systems - heat, power, storage and mobility - in a CO2 neutral closed-loop approach based on green hydrogen.
At each level, all elements will be developed and optimized towards a circular approach, starting with the production of green hydrogen, followed by further processing into synthetic hydrocarbon and nitrogen-based fuels, and their storage, transport and conversion into electricity and heat.
AEM technology development is performed at laboratory scale using multiscale experiments and simulations to develop and verify a novel AEM concept with noble metal-free catalyst and membrane materials. The degradation behavior of the MEA materials will be investigated to evaluate the suitability of these materials for industrial AEM electrolyzers.
