Scientists may have come up with a process to wrap hydrogen-trapping magnesium with an atom-thick layer of graphene, setting up a scenario to store hydrogen in a weight-saving way. Hydrogen seems to be a perfect fuel, but like all perfect things, an unattainable one.  Its lightness and smallness make it hard to contain, and pressurization required to store it adds weight to its containers.  Flying since 2009, the Lange Antares DLR-H2 has been a test bed for hydrogen-fueled flight.  The DLR (Germany’s NASA) explains, “The developers selected a new, larger pressure vessel that, at 350 bar (5,076 pounds per square inch), now holds five kilograms of hydrogen to replace the previous tank in the external pod on the starboard wing, …
