The switch to hydrogen fuel requires efficient and inexpensive storage
- metal hydrides
- liquid organic hydrogen carriers
- amine borane complexes
- imidazolium ionic liquids
- carbon nanotubes
- metal-organic frameworks (MOFs)
and more, but many have drawbacks such as being too heavy, too expensive, not efficient at the right temperature, have low cycle numbers.
Novel and promising hydrogen storage media based on nanoparticle and hybrid systems require advanced synthesis methods (for example microwave-assisted colloidal chemistry) and analytics to study in-operando the chemical reactions occurring during the hydrogen load and release processes at buried interfaces.
