A novel method for determining the degree of hydrogen loading of LOHC using cavity based permittivity measurements

Abstract

Liquid organic hydrogen carriers are a promising candidate to reduce the risk of handling hydrogen. However, the determination of their hydrogenation is still the subject of research. In this paper, a novel method for measuring hydrogen loading based on the permittivity of the hydrogen carriers used is presented. The cavity resonator developed for this application is shown and the design decisions made as well as the processing required are explained. Finally, the results of the test measurements are presented and discussed.
