Filling up with Hydrogen

Abstract:
David Schneider: In June, Honda leased its first hydrogen-powered, fuel-cell car to ordinary consumers, the Spallino family of Redondo Beach, California. That transaction marks an incremental step toward the hydrogen-fueled transportation system that President Bush championed in his 2003 State of the Union Address, when he announced a $1.2 billion "Freedom Fuel" initiative. That program, among other things, funds research on the longstanding problem of how to store hydrogen on a vehicle, one of the many possible showstoppers in the effort to nudge modern society toward a hydrogen-based economy. The trick is figuring out how to hold hydrogen safely and at sufficient density to allow a typical car to go 500 kilometers or so before having to tank up. While that requirement remains a significant hurdle, a new study indicates that the clever use of nanotechnology may give hydrogen storage a significant boost.
