New solid hydrogen-on-demand fuel cell from HES Energy Systems flies UAV for record 6 hours

Green Car Congress

Besides achieving a significant technical and performance milestone for hydrogen-on-demand enabled fuel cells, it is also the first time that a fuel cell has moved beyond the prototype stage and entered the standard products list of a UAV manufacturer. It took HES several years to achieve this performance.

Researchers Improve Performance of Ammonia Borane as Hydrogen Storage Material

Green Car Congress

Hydrogen release measurements at 59 °C on the pristine, 2.0 Ammonia borane (NH 3 BH 3 ) has been of interest as a hydrogen storage material for a number of years because of its high hydrogen content (19.6 mol % catalytic additives, the hydrogen capacity of the system is not sacrificed significantly. mol% Co-doped, and 2.0

Other work focuses on sodium as an earth-abundant alternative to lithium, but while it could lower cost, sodium ions also carry just a single charge. One way is to generate hydrogen by splitting water and storing the hydrogen, as in the power-to-gas schemes under examination (e.g., Rechargeable metal-air batteries.
