Summary

An innovative hydrogen test area for cryogenic high-pressure applications has been put into operation at the ILK Dresden. This test area allows fundamental investigations on hydrogen (in all its phase states) and on gaseous helium. Furthermore, tests and qualification of components of any kind in the temperature range from room temperature down to 10 K and under pressure conditions ranging from high vacuum to 1000 bar are possible. In the framework of a research project, investigations of the charging and discharging process of hydrogen tanks, and the development of new storage technologies to achieve a high hydrogen storage density up to 100 kg/m³ are feasible. Our experiments promote the intricate developments of new components in relation to the handling of supercritical mediums. Thereby, experiments on re-cooling systems in form of capillary expander or Joule-Thomson-cooler are performed as well as on special latent-heat storage systems based on eutectic mixtures. The current status of the development up to test set-ups and experimental results is presented. Furthermore, results of numerical calculations are shown regarding the optimization of process control.
