Efficient multiscale techniques

 Dynamical systems often exhibit a variety of temporal scales. In a recent study we examined the slow degradation of H₂ #electrolyzers under highly oscillatory load.

#Modelling and #simulation is not feasible for long-term predictions spanning months if the fastest chemical scales are also taken into account. Through our #mathematical #analysis, we have been able to separate the scales and achieve accelerations of over 1:1000. This not only reduces the time required for simulations, it also allows to solve optimization and control problems.

Our approach extends beyond the specific challenge of green H₂ production, offering a general tool with broad applicability. As part of the SmartProSys Cluster of #Excellence initiative we are tackling related dynamical problems describing complex chemical conversion processes having the transformation to green carbon-based processes in mind.
