…are about as likely to solve the two little problems of peak oil and global warming as hydrogen fuel cell technology.
Sorry to flog a dead horse here but it’s always worth repeating something, especially if you’ve found someone who can express the idea more articulately than you can.
Joseph Romm of the Center (sic) for American Progress (centrist American think tank) writes eloquently on the reasons why hydrogen fuel-cell powered automobiles are a dead-end and that there are better alternatives:
More than 95 percent of U.S. hydrogen is made from natural gas, so running a car on hydrogen doesn’t reduce net carbon dioxide emissions compared with a hybrid like the Prius running on gasoline. Okay, you say, can’t hydrogen be made from carbon-free sources of power, like wind energy or nuclear? Sure, but so can electricity for electric cars. And this gets to the heart of why hydrogen cars would be the last car you would ever want to buy: they are wildly inefficient compared with electric cars.
I’ve never been entirely clear why investors, boffins, and the popular press like hydrogen fuel cells so much. And why the insist on using the buzzword the hydrogen economy, implying that this is capable of replacing our current oil-based transport setup. Is it just because the cars themselves don’t emit any carbon dioxide during operation? I don’t know, but I suspect some people, including automakers Honda are in for a nasty shock.
