Hydrogen is seen as one of the major storage options for renewable energy. However, its storage still faces a number of challenges. Safe, dense and efficient hydrogen storage has to overcome a number of thermodynamic constraints. A big issue, for example, is the compromise between simple hydrogen release with a small energy demand on the one side and loss-free storage at ambient conditions with a high density on the other side. The interplay between enthalpy and entropy change during hydrogen uptake plays an important role in this respect.

In this contribution different steps in the development of hydrogen storage technologies, such as Liquid Organic Hydrogen Carrier (LOHC), will be presented. First, a study on the identification of potentials for the improvement of hydrogen storage technologies is conducted. This outlines the impact of different measures and gives insight into the question what should be improved.

Based on these findings, a systematic development of carrier materials and technologies will be demonstrated. A comparison of different hydrogen storage options is discussed.

The role of process simulation in this context will be outlined. In the last step a special emphasis will be put on the issue of reliability and uncertainty of the respective process models.
