As usual, these numbers are cooked to make batteries look better than hydrogen. There are companies offering solar catalytic hydrogen generators and other offering high efficiency compression / storage systems and cheap efficient fuel cell tech.I find this paper to be interesting on this topic.
Same ole arguments -Texas,
I agree with you.
Extracting H2 out of fossil fuels (HC) leaves CO2 in the atmosphere. Aren’t we supposed to reduce CO2 emissions? Then, break the water into H2 and O2 by electrolysis, hydrogen loving people say. If you have such abundant electricity, be it solar, wind or nuke, why don’t you store the electricity in batteries or capacitors and drive the car directly rather than using an intermediary energy carrier? Besides, platinum (essential catalyst for fuel cells) is scarce and expensive. Of 200+ tons of annual production (plus 15 tons or so recycled) automotive industry already consumes about 50% of platinum and its family metals for cat converters. Demand will increase rapidly as European automotive manufacturers start using platinum to clean diesel exhaust and Chinese and Indian automakers increase their production. Major suppliers of platinum are Sough Africa and Russia. Do you want to drive your car at their mercy? (if you use hydrazine in place of hydrogen to make fuel cells you do not need platinum, though. But, that's another story.)
I think GM, Honda et al are showing and talking about fuel cell automobiles as political ploy.
Can you give us prices? How about where interested individuals can buy them? I would like to make a fuel cell car. If they are cheaper than batteries and ICE technology I should be able to spend less than $2000! Thanks for the accurate information Jason. You are doing people a great service. <sarcasm>- batteries and supercaps are far more expensive than fuel cells, which are already cheaper than a gasoline ICE
That's exactly what I am claiming. Prior to the breakthroughs in platinum catalyst reduction / replacement, GM and other automakers insisted that fuel cells had to drop 75% in cost to be competitive with gasoline ICE's. Using nickel platinum alloy and nano compounds, more than one company has surpassed this goal. Moreover, fuel cells only need to be 70 hp in E-REV configs, instead of the currently equipped 140 - 220 hp that similarly sized vehicles have today, so fuel cells are much, much cheaper, by automakers own stated targets.Also, even if they did get the cost of the fuel cell itself down you have to look at the whole system cost. I'm talking about the fuel storage system and the temperature control system. Are you also claiming that with today's technology a fuel cell system is cheaper than A123's batteries (that are now on sale - not the auto packs - equivalent power)?
