At TU/e, a myriad of researchers is working on hydrogen. Research challenges vary from how to generate hydrogen through intermittently driven electrolysers, to how hydrogen storage is used to manage demand and consumption of electricity under a wide variety of operating conditions. Around 140 researchers are, together with industry, executing projects on for instance the modelling of alkaline electrolysers, cost-effective production of electrodes, the purification of mixtures with Palladium coated membranes, the performance modelling of larger sized solid oxide cells and so on. An internal TU/e Hydrogen Community was established to bundle efforts, share experience on this topic, enhance TU/e's contribution through internal and external collaboration and showcase our research and education on hydrogen. One of the activities of the Hydrogen Community is the organisation of a Eurotech hydrogen summer school for international PhD students, to follow up on a previous two editions organised by DTU in Denmark and the Ecole Polytechnique in France.
