Non-critical Materials Production for a Green Energy Transition — •Anke Weidenkaff, Wenjie Xie, and Marc Wiedenmeyer — Technische Universität Darmstadt

The defossilisation of the energy sector requires a green infrastructure for efficient renewable energy converters.

The new infrastructure cannot be based on critical materials. Therefore, the transformation to a future fossil free green circular economy will be based on sustainable materials production processes and ecologic innovations.

The development of renewable materials for renewable energy converters requires the development of an affordable but sustainable large-scale production from secondary raw materials. The decision making for future resilient energy systems has to be based on fair, ecological and economical aspects and data from performance criteria defined by a holistic life cycle assessment.

In this lecture a recycling / production of materials with a programmable lifetime and self regeneration will be introduced as a suitable approach.

The design of circular high performance materials uses theoretical predictions and the criticality analysis of applied elements to improve the cycle life of future energy converters such as thermoelectric generators and refrigerators, batteries, electrolysers, fuel cells, plasmalysers, hydrides and solar watersplitting cells.
