Hydrogen packs a lot of energy into a tiny molecule. Furthermore, when you burn hydrogen, you don't get soot and suffocating gases-you get pure water. But hydrogen does burn easily. Wescott showed a photo of the fiery end of the zeppelin Hindenburg to remind his audience of why people worry about hydrogen's capacity for too-exuberant combustion. It's tough stuff to handle safely.
Zeolites make an excellent and safe storage medium for hydrogen.
Hydrogen is so keen to combine with other elements that there's no way to mine it like coal or pump it out of wells like oil. It has to be pried out of its compounds. Alaska is well supplied with one of those compounds-water. In fact, the Aleutians are virtually afloat in an ocean of it. Getting out the hydrogen can be expensive, though.
