The aim of the H2-INES project is the integrative increase of the safety level in the hydrogen value chain. In order to achieve this, the Chair of Hydrogen and Nuclear Energy is conducting risk assessments for technical and human error, while deriving safety-related optimisation recommendations from these assessments. The H2-INES project is integrated in the HYPOS network and accompanies selected projects in order to generate application-orientated results and utilisation synergies.

In this project, TiO2 nanostructures are developed, which generate enhanced electromagnetic fields on the TiO2 surface when exposed to light. This local light amplification will be used for the analysis of surface-bound molecules by means of Surface-Enhanced Raman Spectroscopy (SERS). On the other hand, the influence of the local light amplification, quantified by the SERS signal, on the photocatalytic efficiency of TiO2 will be investigated. Due to the SERS amplification of the catalysts on the TiO2 surface, reaction intermediates during electrocatalysis will be detected.

The Chair of Theoretical Chemistry uses computer simulations (Grand Canonical Monte Carlo) to investigate the storage of hydrogen in multi-layer graphene systems. Model systems consisting of infinitely parallel graphene layers with defects of different sizes were considered. It was shown that the incorporation of defect leads to an increase in theoretically possible surfaces that go beyond the limits of ideal defect-free graphene. This leads to promising hydrogen storage capacities.
