pennor1, I agree that we should not only cheer the efforts but help fund aggressive research. However, we need to be very diligent that interested parties do not use hydrogen as a way to divert funds, hinder consensus or delay transition from our oil economy. Do you think it's not important to get the facts correct?COOL! I mean REALLY COOL!!!!!
Rather that find fault with hydrogen, or any other alternative fuel, let's cheer the efforts. I for one am greatly encouraged by this announcement.
According to that Wickepedia article, hydrogen fuel cells have theoretical max efficiency of 83%. Even though the pratical efficiency for fuels for automibiles will be significantly below this it will still be quite good. Also, fuel cells capable of displacing the genset in the Volt are very expensive today but it is very conceivable there costs can come down to below the genset. The difficult issues that do not have good answers for yet are effectively isolating, storing, and distributing the hydrogen. This is where the efficiencies and costs are difficult to resolve. Personally, I believe hydrogen fuel cells are very cool and will have their places, just not in my car. I have no interest in trading gas for hydrogen as my feul until we have a surplus of inexpensive, clean energy that would otherwise be wasted.
I think, when discussing hydrogen, we focus too much on the hydrogen that is generated from electricity. There are other forms of generating hydrogen. I'm not 100% sure of the processes in these chemical reactions, but check out : http://www.millenniumcell.com/fw/main/Overview-27.html and http://www.millenniumcell.com/fw/main/How_it_Works-31.htmlHydrogen: Can be burned directly or used in fuel cells to make electricity. It's relatively easy and quick to refuel a hydrogen car. The only polution from from combustion is water. It can be made from water using electricity. But, curretly it's "cracked" from fossil fuels releasing lots of CO2 in the process. There's no fueling infrastructure setup. To "crack" hydrogen from water requires a whole new electricity generation paradigm of solar, wind, wave or nuclear power to make the product without polution.
Am I wrong or does Archer Daniels Midland not have a multi-hundred-million dollar contract to produce ethanol from corn? Yes, cellulosic ethanol is a much more efficient way to go than corn. But where is the evidence that production plants are moving to these methods over corn? If you have some specific information on this transition from corn to switchgrass, please share it.Texas,
Right now, people are trying to tear down ethanol, without understanding that many production plants are moving to switch grass and other cellulous sources.
