The National Renewable Energy Laboratory in Golden, Colorado released a document last year on the viability of fuel cells for various applications, including transportation. The National Fuel Cell Electric Vehicle Learning Demonstration Final Report, “analyzed data from more than 500,000 individual vehicle trips covering 3.6 million miles traveled and more than 152,000 [kilograms] hydrogen produced or dispensed.” The agency tested 180 vehicles over a six-year period. With United States Department of Energy expectations that fuel cell powered vehicles could achieve: • 250-mile driving range • 2,000-hour fuel cell durability • $3/gallon gasoline equivalent (gge) hydrogen production cost (based on volume production) At least two fuel cell manufacturers report results exceeding these numbers, so the major impediment to wide-spread implementation of this clean technology seems to be lack of an effective distribution network. The NREL lists 54 existing H2 sites, with 15 projected for the near future, nowhere near the estimated 159,000 outlets (including convenience stores) that sell gasoline and other …
Hydrogen Scooters – A Possible Power Source?
Amateur aircraft builders, like Francis Marlier of the ULM Club in Alsace, France who recently converted his Exelec to a Sunexelec with the addition of solar cells, are always looking for reasonable options for powering their airplanes. Perhaps they could turn to fuel cells as a range extender. Several motor scooter makers are bringing out fuel-cell powered models that show some promise despite limited performance and high prices so far. Intelligent Energy, an English company, demonstrated a fuel cell scooter in 2005, and a number of aircraft developers, including Boeing, have crafted fuel-cell-powered vehicles. Intelligent Energy’s ENV was reportedly the world’s first purpose-built fuel cell motorbike, and Top Gear’s James May enjoyed the quiet ride, if only moderately endorsing the bike’s sedate performance. http://www.youtube.com/watch?v=igrKemNvxZQ Intelligent Energy’s entry for the Make It in Great Britain exhibit at the Science Museum gives a brief overview of proton exchange membrane fuel cell technology. “This award winning zero emission electric vehicle is powered by Intelligent …
