Time to Come Clean About Hydrogen Fuel Cell Vehicles

Hydrogen Production from Natural Gas (Credit: ceram.material.tohoku.ac.jp) Click to enlarge.
Hydrogen is a fossil fuel.  95% of US production is from natural gas, most of the remainder from the gasification of coal, and it will not change for the better.

The Ford Motor Company:  “Currently, the most state-of-the-art procedure is a distributed [on-site] natural gas steam reforming process.  However, when Fuel Cell Vehicles (FCV) are run on hydrogen reformed from natural gas using this process, they do not provide significant environmental benefits on a well-to-wheels basis (due to GHG emissions from the natural gas reformation process).”

The heavy conversion loss from electricity to chemical fuels drastically impacts the distance that can be traveled per unit of energy depending on source.  The least cost pathway per mile for FCVs is so pronounced in favor of natural gas versus electricity from any source as to guarantee steam reforming trumps electrolysis, without CO2 sequestering and with no reason for the natural gas industry to fear cost per mile competition from renewables.  Accordingly, should FCVs be adopted, natural gas will prevail economically long into the future, and long after the date by which EVs could be operated economically on 100% clean renewables on a large scale to the exclusion of fossil fuels.
