The ChiPs are down for the hydrogen highway cul de sac -- literally. The future Ponches and Jons of the California Highway Patrol won't be policing the hydrogen highway.
The false hope of a hydrogen economy is on its death bed. This dream was embraced and elevated by President Bush, who said in his January 2003 State of the Union address:
With a new national commitment, our scientists and engineers will overcome obstacles to taking these cars from laboratory to showroom so that the first car driven by a child born today could be powered by hydrogen and pollution-free.
I have explained at length many times why the first car of child born in 2003 -- or the last car, for that matter -- will not be a hydrogen fuel cell car, most notably in my best selling book, The Hype About Hydrogen [Note to a picky semantic people: The book was not a best seller, but it was the best-selling of all of my books]. Maybe my best (and certainly my most widely read) paper available online [PDF] is "The car and fuel of the future," published by Energy Policy back in 2005. It is still worth reading if you want to understand why plug in hybrids, not hydrogen fuel cell cars, are the car of the (near) future.
The last vestiges of a hydrogen economy are collapsing. First, we had Honda's new FCX Clarity, which the company optimistically billed as "the world's first hydrogen-powered fuel-cell vehicle intended for mass production." If so, the Clarity has demonstrated to the world how distant the whole enterprise is (see here, here and here).
Now Greenwire ($ub. req'd) has a long story on the collapse of another one of the few remaining pieces of the dream, "Has Schwarzenegger's hydrogen highway gone bust?" excerpted below:
