Proposed nano carbon could pack in hydrogen

Form molecule-size pillars on one-atom thick sheets of carbon, load the material with lithium, and you have a good way to store hydrogen at room temperature, at least in theory.

A computer model of a nanoporous carbon material shows that it would store up to 41 grams of hydrogen per liter. The US Department of Energy's 2010 goal for hydrogen storage materials is 45 grams per liter.

Finding an efficient way to store hydrogen is a key requirement for practical hydrogen vehicles.
