Hydrogen storage on a disk

One of the biggest challenges to fuel cell vehicles is storing hydrogen which, when fed through a fuel cell, will make electricity to move a car. Plasma Kinetics is looking for funding to further develop a system that uses disks made mostly from magnesium to store hydrogen molecules.
About 10,000 of these disks, which would take up about as much space as a car back seat, would allow for a driving range of over 200 miles, according to Executive Vice President of Research and Development Paul Smith. The hydrogen would be removed from the disks using lasers, he said.
