Green Car congress has more details on the vehicle. From the specs it appears to be a short range vehicle, but it's very clean. It's a good start that is best for urban duty at this point.

Ovonics (part of Energy Conversion Devices) has a different hydrogen storage system that they're promoting, and just introduced their own fuel-cell test car to California:

They're saying they get a range of just under 200 miles (vs. maybe 130 miles in Quantum's extended range package), plus you don't have to worry about a tank being pressurized to 5000 psi. The Ovoncis press release doesn't say who did the fuel cell portion however, and it's a single car (for now).

Ya know, I've stopped caring about H for cars. Take a look a darreld's website (http://www.darelldd.com/ev/).

Read ALL of it and the links. It's mind-boggling the disinformation and conspiracy surrounding H over straight EVs. We are truly a gullible and stupid species sometimes...

i recently attended the World Hydrogen Fuel Conference in Long Beach this past Tuesday, and had the opportunity to talk with the rep from Quantum about their H2 Prius.

Interesting concept, and i was really impressed with their development and testing of individual components as well as complete systems. However, what struck me as odd, was the limited range available with the hydrogen fueled cars: 90-140 miles!! thats a whole lot of time spent at the pump!

Until they can get the storage problem taken care of, I don't think hydrogen is a viable option for the consumer market.

They will get the storage problem sorted one day.

What they can't do is rewrite the rules of thermodynamics. EV (or plug-in hybrid in EV mode) will always use about a quarter the amount of energy as a hydrogen fuelled car, and that means consumers will be expected to pay at least 4 times as much to fill up with hydrogen.

If somebody offered you a carbon-neutral, totally clean fuel you could run in your gasoline vehicle today, but you had to pay $12 per gallon for it, would you buy it?

Frankly bizarre that GM think there's a strong business case for this whole hydrogen thing.

Wait, wait, I'd like to retract my above post...forgot subsidies to the oil companies to MAKE hydrogen work...that ought to bring the price down. Hmm, just like gasoline...hmmm...

If the Prius hat twice the battery could you get 400 miles per tank?

i lived in Riverside for 7 years, if there was ever a place that can take advantage of the advancement of wind (they do have a lot of wind farms) and solar, that is the place. March and Norton AFB are located there because of the near perfect flying weather, which also means a near perfect solar collection environment.

San Bernadino, being the largest county in the country, has TONS of wide open space not being used for anything except as scorpion condos... its close to a major Electricity user (Orange and LA counties) so, there can be a viable VERY large scale project that i feel would work out there. sure the intial outlay would be expensive, but it needs to be done.

as far as hydrogen goes, unless you are in an area where you can tap unlimited geothermal energy safely, then hydrogen is a waste of time and money. its simply not viable
