High Performance Center - Green Materials for Hydrogen, HesseThe requirements for new hydrogen technologies are many and will become more stringent in the future.
These are:
- Safety
- Economic efficiency
- Environmental protection and resource efficiency
- Technical practicability & performance
For the development of new materials as well as the operation of generation plants and applications, it is therefore necessary that all relevant criteria are considered from the very beginning. Only then can technologies survive and be put into practice on a large scale. Aspects of sustainability are just as relevant as those of technical performance. A list of criteria for the development of new catalysts for electrochemical hydrogen electrolysis (OER: Oxygen Evolution Reaction) was developed at Fraunhofer IWKS in collaboration with the Max Planck Society [1].
The complexity of the properties and processes makes the use of digital models necessary. These not only make it possible to holistically improve individual processes as well as an overall system of material and product life cycles, but also to uncover previously unknown physical relationships and thus better understand products. The MPPM method can be used to compare different types of processes and to identify the best alternatives for the production, operation and recycling of valuable functional materials.
