And even if the reformer could be made practical and affordable, there is still the remaining problems with fuel cells themselves: very bad cold weather performance, expense, expected lifetime, crash performance, etc.
Yes, the Voltec can be powered with any electricity generator, but it seems to me a six-stroke engine is not a big technical stretch (new camshaft ? reprogram the Engine Control Unit ? It's like an Atkinson-Miller engine compared to an Otto - just a few tweaks). For a design just introduced in 2006 (the Velozeta six-stroke engine, of India), perhaps the idea has not spread much yet, but it seems it could easily be applied to an existing, say, 1.4 liter I-4 engine ... Maybe licensing fees are too high ? |

Maybe...but then again, perhaps progress is being made.
http://www.plugpower.com/technology/...velopment.aspx Research & Development Plug Power Research and Development Partners ExxonMobil Exxon Mobil Corporation is partnering with QuestAir Technologies, Plug Power Inc. and Ben Gurion University on plans to commercialize an on-vehicle hydrogen production system for use in a fuel cell-powered lift truck application. The unique technologies under development by ExxonMobil, QuestAir Technologies and Ben Gurion University will convert liquid fuels -- gasoline, diesel, ethanol or biodiesel -- into hydrogen onboard the vehicle where it will be used in a fuel cell power train. Plug Power will integrate the new technologies into its GenDrive fuel cell power systems for lift trucks to drive future commercialization efforts. The new system will convert liquid hydrocarbons into hydrogen directly on a vehicle without the need for storage, leveraging significant infrastructure, logistics and cost advantages compared to other hydrogen vehicle systems, all while reducing the impact on the environment. The system does not require changes to fuel delivery infrastructure. |

The French have a saying:
If I had some cheese, I could make a cheese omelette, if I had some eggs. If Exxon had a reformer, they could build a gasoline-fueled fuel-cell powered lift truck, if they had a fuel-cell. |

http://www.ztekcorp.com/hpsr.htm How about installing these at gas stations. No they are not CO2 free, but the claim is, "ZTEK commercial hydrogen reformers will convert gasoline, natural gas or methanol to hydrogen at 85% efficiency, meaning that 85% of the energy contained in the fuel will be converted into useful hydrogen." I wonder what the equivalent MPG of using this system with the Chevy Equinox Fuel Cell test vehicle would be? Would this not be more efficient than using an ICE-Genset? That is, do the reforming of gasoline into hydrogen at the gas station, then use a fuel cell in the Volt? Just food for thought/discussion, it would be an interesting first step to making a hydrogen economy a reality? |

These things get amazing economy for their vehicle category. (I know, I own TWO of them- a pickup AND a Tahoe) However while the Yukon/Tahoe/Escalade versions of the 2-mode are over $10,000 more- the reality is they come standard with a LOT of additional equipment that you would normally pay extra for. Sure the price tag of "loaded to the nuts" SUV isn't for everyone, but I love mine and plan to trade it in on a newer 2010 model in the Spring (it's an 08) According to "Automotive News" data services, sales of the GM 2-modes have been steadily increasing to the point GM is now #2 in USA hybrid sales.(but still significantly behind Toyota) WopOnTour |
