"Speaking at the JP Morgan Auto Conference in New York, Toyota’s senior vice president Bob Carter said that Department of Energy estimates suggest that a full tank of compressed hydrogen will cost around $50. This will fall to $30 in time, however." http://ecomento.com/2014/08/13/bullish-toyota-admits-hydrogen-wont-be-cheap/ I had always assumed one of the messages FCEV advocates would advance is the "cheap, free, plentiful, most common element in the universe" story. At $50, its not too far off what it costs me to fill up my Jeep. Actually, $50 is almost exactly what gets racked up on the ToU dedicated EV meter each month for my Tesla.
