    But how many kwh does it take to produce a kg of H2?

    Hey, BFD, how's that 2 hour recharge in the middle of the Mojave desert working for you?

    Sometimes you start out a project using short term methods to get it going. The methods will be refined later on as the market develops.

    It's all in the assumptions, and comparing apples to kumquats. Tell us how a hydrogen bus using wind or hydro power to generate hydrogen pollutes more, and a battery based electric bus has the same range as a hydrogen bus.

    So GulliBill fell for the deceptively stated statistic again? Surprise, surprise…..

    First of all, I don't think the bar is 10,000 psi. I think the most likely psi will be around 7500.

    Don't have time to search now - leaving on a trip tomorrow morning. But I want to comment on a few of your jabs.

    "And how did we get from H2 production costs to the Iraqi war?"

    You're the one that rants about costs but ignores the true cost of oil.

    " I'm sure Bush lost the IRS files,"

    Well, he couldn't find those WMD's he used to justify the war...

    "abandoned people in Benghazi,"

    Read Politifact's article on attacks on embassies during the Bush Administration. Maybe you'll shut your stupid closed mind uneducated yap when you find out how many died under his watch. (But I suppose they don't count, because the vast majority weren't 'Merican's)

    "funded and performed Fast and Furious,"

    Yup, the whole concept was started under Bush

    "grossly expanded the NSA invasion of privacy"

    You do realize under which administration the Patriot Act was passed and signed, don't you?

  • groundhogsteve groundhogsteve Jul 22, 2014 7:44 PM Flag

    "And remember, wind only blows 20% of the time, so equipment utilization is going to be p**s poor. "

    That's factored into the cost.

    Theoretically (bur probably not practically), you could have a process that operates at 10% efficiency be viable - as long as it is cheap.

    "It takes 60 KWH to electrolyze and compress one KG of H2."

    Oh, so we've gone backwards in power demand - years ago, one of the electrolyzer companies could produce and compress a kilo for 55 kwh. Now it's less efficient - 60 kwh? Did we forget something? Or did aliens erase our memory of how to do it for 55 kwh?

    "per my windpower magazines'

    You mean "Wind Turbine Hunter's Guide"? Or "Wind Hater's Journal"?

    "So you are in for a minimum of $6.60 for your power bill."

    And how much did that Iraq War cost? Don't you like to rant about increasing deficits? Or are you still of the child-like belief we were 'liberating' Iraq? And do you think Saddam invaded Kuwait for it's nice sandy beaches?

  • groundhogsteve groundhogsteve Jul 13, 2014 12:58 PM Flag

    No, BFD, it's you that does the whole "WE'RE ALL GONNA DIE!!!" routine in regards to FCV's, although you use slightly less dramatic words, more the scary words with ominous tones technique.

    So I just rephrase it to "WE'RE ALL GONNA DIE!!!" for you, to illustrate your stupid panicky approach to the matter.

    "The debt has risen $7T on the books with a similar amount off the books. "

    Tell us, GulliBill, which president kept the Iraq War off the books, and which president put it on the books?

    Get a life, GulliBill.

    And you believed that one too? I suppose you saw the picture and said "Aha! That's all the proof I need!"

    While ignoring the point that there didn't seem to be any wear on the shoes......and the logo was a crisp and clean after walking how many miles in the dirt and sand and through the cactus and sagebrush? Or has the rumor been embellished now with Obama providing paved walking trails tot eh border?

    GulliBill is certainly an appropriate name for you.

    BTW, Bill, you missed the better one - the government contract for - ahem - "Escort Services" for illegal aliens, where Obama is going to turn the kids into sex slaves.

    Multiply 129 times 440,000 birds, it means that generating enough hydrogen to cover all our petroleum needs would kill 56.9 million birds - even if there is no improvement in the birds killed per kwh generated factor.

    Cats kill an estimated 2.4 Billion birds per year. Or 42 times the number the wind turbines generating all that hydrogen would.

    Get your priorities straight, GulliBill. If you're truly concerned about bird kills (which I doubt), then work on eliminating cats. How many cats per mile do you kill with the 'Vette?

    GulliBill-

    Still believe BP gave super duper gazillions to Obama?

    Still believe the Obama brownshirt corps are coming?

    GulliBill be thy name. A very appropriate name. You actually believe that "stuff".

    "... a guy who believes we can convert wind power to hydrogen in enough quantity to power America."

    Let's assume for the moment we're consuming 20 million barrels of oil per day, and you get 39 gallons of product per barrel after refining. So we consume 780,000,000 gallons of petroleum fuel per day., or 2.847 x 10^11 gallons per year.

    The US has an estimated annual 37 petawatt hours of wind resource. Divide by 55 kwh per kilogram via electrolysis, you get 6.72^11 kg of hydrogen, and as we all know, each kg is roughly the energy equivalent to a gallon of gas, (except that FCV's can go further on the kg of hydrogen than a car can on the gallon of gas).

    6.72 x 10^11 divided by 2.847 x 10^11 = 2.362. That means we have 2.362 times the amount of wind energy it takes to do a straight up hydrogen for petroleum trade. Given that a lot of efficiency can be gained by having hybrids with 40 miles battery range, so you can utilize the battery charging more efficiently for most driving than going through the hydrogen cycle, we probably have 3-4 times the amount of wind energy it takes to replace all our petroleum use (on an energy basis, not talking about form and density for airplanes, etc).

    So even if we have on heck of a NIMBY problem that only allows only half of our wind potential to be developed , I think there's enough to replace the US' oil consumption. And we cold also do solar, too.

    Bird kills? The Fish and Wildlife Service estimates 440,000 birds are killed by turbines each year, while generating 121 Twh. If we were to replace all petroleum products with hydrogen, it would take 1.565 x 10^16 wh, or 129 times the amount of wind energy generated today. (Continued next post)

    jj-

    If you took every ounce of soybean oil, cottonseed oil, and all rendered fats and turned them into biodiesel, it would amount to 11% of our total diesel consumption.

    I doubt you could come anywhere near 15% growing algae.

    Google Halliburton Fluids Disclosure. They give their different components.

    While they don't give the recipe of percentages, they disclose all the chemcals.
