What makes you so sure that hydrogen would be sold in the US in kilograms? Someone would insist that the sale to the American consumer be strictly in pounds. No matter what the cost of the logic against it, pounds it will be.

However, while gasoline will eventually go away, H2 might never catch on due to advances in battery technology, which could make electric cars more practical. Sadly, my guess is that this will happen, but here's an article arguing otherwise: http://hydrogendiscoveries.wordpress.com/2009/02/19/fallacy-of-energy-efficiency-argument-against-hydrogen-fuel-cell-vehicles-by-plug-in-battery-advocates/ and another: http://www.autobloggreen.com/2009/03/03/retech-2009-hydrogen-proponent-sandy-thomas-says-fuel-cells-bea/ On the flip side, there's a company called EEStor in Texas that claims to have developed an ultra capacitor that will power a car for decent range, and unlike batteries can be recharged in minutes and will never wear out. If that's for real (no prototype has been demonstrated) goodbye H2 as the car fuel of the future and a fleeting victory for the kg. http://gm-volt.com/2008/03/28/zenn-says-eestor-ultracapacitor-powered-car-for-launch-fall-2009/
