New Generation Hydrogen – How to Package Pastous Hydrogen for Mobility Applications

Future mobility will depend on low-emission technologies to achieve the climate targets sets and to reduce the effects of climate change. Therefore, green hydrogen can be a key component in specific mobile applications in order to provide low-emission mobility. Unlike conventional hydrogen storage, the newly developed Powerpaste does not have high pressure and temperature requirements. The paste-like hydrogen storage system, therefore, enables simplified storage, handling and transport. Likely mobile applications for Powerpaste are car sharing, intralogistics or courier, express and parcel services. These three application scenarios lead to specific requirements for a suitable Powerpaste container. A literature study is conducted to set up criteria which support the selection of a suitable container. The criteria are categorised using expert workshops and evaluated using the methodology of pairwise comparison. The resulting categories for the criteria are application, logistics, recycling and safety. Two exemplary container concepts are compared and evaluated on the basis of the criteria sets: bag-in-box and piston cartridges. The piston cartridge is rugged and suitable for the transport of dangerous goods and enables simple integration into the car. At the same time, the bag-in-box concept is advantageous from a logistical point of view.
