The benefits of hydrogen are fairly obvious. It would almost necessarily be a domestically produced material with few environmental shortcomings if made by clean processes. The challenges to be overcome are many and varied, though – with the biggest obstacle to wide-spread use being in the distribution of the fuel. The U. S. Department of Energy, on its Fuel Economy.gov web site, concedes, “The current infrastructure for producing, delivering, and dispensing hydrogen to consumers cannot yet support the widespread adoption of FCVs (fuel cell vehicles).” As different strategies are tested and adopted, this is likely to change, as are the costs for fuel cells and their longevity.
