econh2.jpgWhen the world’s uber-centrist magazine of choice runs a headline almost identical to mine, you know it’s all over. Especially when one of that magazine’s leading energy columnists, Vijay Vaitheeswaran, used to sing that technology’s praises (here). Here’s the bottom line:

But the promise of hydrogen-powered personal transport seems as elusive as ever. The non-emergence of hydrogen cars over the past decade is particularly notable since hydrogen power has been a darling of governments worldwide, which have spent billions of dollars in subsidies and incentives to make hydrogen cars a reality …

Here’s the fatal flaw in the H2 economy:

… The logistical, technological and economic problems facing hydrogen fuel-cell cars mean that they are very unlikely to make it to market any time soon. One thing holding back hydrogen vehicles is a chicken-and-egg problem: why build cars if there is nowhere to fill them up, or hydrogen filling-stations if there are no cars to use them? Just around the corner, honest.

But wait, here’s another fatal flaw in the H2 economy:

How much more investment is needed to make mass-produced hydrogen cars a reality? According to a recent study by Oak Ridge National Laboratory, sponsored by America’s Department of Energy (DoE), public funding of $10 billion would be required to get 2m hydrogen fuel-cell cars onto America’s roads by 2025, rising to $45 billion for 10m cars. A report issued by America’s National Academy of Sciences in July was less optimistic, estimating that $55 billion of government investment would be needed to put just 2m hydrogen cars on the road by 2023. And both reports assume that the technology will get a lot cheaper: the Oak Ridge study assumes it will be possible to make fuel-cell vehicle systems in quantity at a cost of $45 per kilowatt of output by 2010, and $30 per kilowatt by 2015.

This is ambitious. Although fuel-cell costs have dropped by 65% since 2002, according to the CaFCP, today’s fuel cells cost around $107 per kilowatt. Are sudden cost reductions around the corner? Not according to one of the pioneers of fuel-cell technology, Ballard Power Systems, a Canadian supplier of fuel-cell systems to a range of carmakers. In November 2007 it sold its automotive fuel-cell division to Ford and Daimler after a decade of losses, citing the “realities of the high cost and long timeline for automotive fuel-cell commercialisation” for its exit from the business.

Actually, the CaFCP’s cost claim is laughable. You can’t buy a warranteeable fuel cell for a car for $107 per kw today. Try more than 10 times that, over $1,000/kw. The CaFCP number is a projection based on the assumption of mass production — hundreds of thousands of units a year — with no explanation for the high quantity of sales levels for cars whose best current generation models cost hundreds of thousands of dollars apiece.

As I wrote in Technology Review, one of the only car companies in the world still seriously pushing hydrogen cars, Honda, hopes that in a decade or so, production volume would drop the car cost to “below $100,000.” As if that price would make it attractive to anybody but the super-rich. But in any case, why would production volumes increase for a car that delivers no real value to the consumer and has no significant societal benefit to motivate government support? Answer: They wouldn’t, so prices may never drop below $100,000. That’s why Ballard left the business.

Hydrogen cars have no future, or, as The Economist‘s headline puts it, hydrogen cars, like fusion energy, have the same future they always had.

And here’s another bunch of fatal flaws:

Even if the network of hydrogen filling-stations can be built, and the technological advances needed to reduce the cost of fuel-cell vehicles can be made, a huge problem still remains: the production and delivery of hydrogen in large quantities. The Oak Ridge study says the two most promising ways to produce hydrogen cheaply in the near term are to make it from natural gas (through a process called “steam reforming”) at the filling stations themselves, or to make it from gas derived from biomass or coal at large, centralised plants, and then deliver it by lorry or pipeline.

Hydrogen sceptics point out not only the large capital costs associated with the production, transportation and storage of hydrogen, but also the availability of far more viable alternatives. Hydrogen is “just about the worst possible vehicle fuel”, says Robert Zubrin, a rocket scientist and the author of Energy Victory, a book on the post-petroleum future. Even if the requisite gains in fuel-cell technology are achieved, he says, the fuel-cell cars of the future should run instead on methanol, which has a higher energy-density than hydrogen and can be stored and transported much more easily.

Furthermore, steam reformation of natural gas is far from a zero-emissions solution, undermining the whole rationale of hydrogen cars in the first place. According to America’s National Renewable Energy Laboratory, producing a kilogram of hydrogen by steam reformation generates emissions equivalent to 11.9kg of CO2. Given that the Chevy Equinox fuel-cell vehicle can travel 39 miles on a kilogram of hydrogen, and the FCX Clarity can travel 68 miles, powering these cars using hydrogen produced by steam reformation would result in emissions of 305 and 175 grams of CO2 per mile respectively. By comparison, today’s petrol-electric Toyota Prius hybrid produces tailpipe emissions of around 167 grams per mile, and many small petrol cars achieve similar results.

Seriously — how many fatal flaws does the technology need? Hydrogen cars were apparently killed in the drawing room by the knife, revolver, lead pipe, rope, and candlestick.

The magazine includes as an afterthought yet another major fatal flaw, one that I have written a lot about. While some say “the solution to large-scale hydrogen production lies in using renewable electricity to extract hydrogen from water via electrolysis” or using “nuclear power. But it would surely be easier simply to use this energy to charge the batteries of all-electric or plug-in hybrid vehicles.” Easier, hundreds of billions of dollars cheaper, and you don’t throw away 75 percent of the valuable carbon free electricity in the process!

Some people cling to the notion that hydrogen can be reanimated like Frankenstein’s monster (see here). But the Economist article ends more realistically:

In other words, claims that hydrogen will be the automotive fuel of the future are as true today as they ever have been.
