Interesting point they make that a gallon of gasoline (at room temperature) actually has more hydrogen in it than a gallon of liquid H2 (at 4 Kelvin).

If they can actually make hydrogen storage in carbon work (it has to be pretty robust to field in a car), then it could have some interesting implications for propellant depots...

A propellant depot can use several storage tanks to refuel a spacecraft.  Room temperature storage may exist but there is still 'boiloff'.
