This article's conclusions are based on flawed assumptions. First, the efficiency of fuel cells is far greater than that of engines, 2.5 to 3 times as great, when used in fuel cells. Gasoline doesn't work in fuel cells because it is too chemically complex "gums up the works." So, if gasoline is $2.50 per gallon, the equivalent price for hydrogen works out to somewhere around $7.00 per kg.
In addition, it is possible to produce hydrogen directly from water using renewable energy (e.g., wind turbines) as the initial source, and get it to market for a cost that is competitive with gasoline and diesel on a cost-mile-basis.
