Hydrogen transport and storage are critical for the roll-out of a hydrogen economy, especially because the associated burden could comprise 35 % of the overall greenhouse gas footprint. As a result of hydrogen‘s low volumetric energy density, its long-distance transport and local distribution is difficult. Physical methods such as compression and liquefaction have been explored as possible options. Also chemical methods of incorporating it into Liquid Organic Hydrogen Carriers (LOHCs) and sorption into solid phase materials have been investigated. RA2 brings together many of these interesting topics under the following subtopics:

1. Electrochemical hydrogen compression
2. Chemical hydrogen storage
