you would need to drop the temps down to 20 kelvin (MORE THAN 400'f NEGATIVE) to get liquid hydrogen. it is VERY VERY difficult and expensive to make liquid hydrogen and EXTREMELY DIFFICULT to keep it liquid without tons of power and specialized equipment.

that tank ONLY contained mildly compressed hydrogen gas.

your nitrous system is a bad example. it was OXIDIZER not FUEL. our vehicles use a LOT more oxidizer than they do FUEL. just stick your hand over your air intake to see how much. what is it 14 to 1 or something like that?

Liquid hydrogen is what? around 70grams a liter. there are 453 grams in a pound.

those tanks hold a hell of a lot more than 6.4 liters IE as a liquid it would hold a whole lot more than a pound of hydrogen.

its JUST gas. no liquid.

Yeah your right my bad

I just wish the mythbusters did not so quickly "move along" and utterly IGNORE the amazing thing they just did. Grrr makes me mad. Just a few more details. one of these days I will have the cash to rent a tank and I will find out just how much hydrogen it takes to run a car and just how LITTLE one needs to have a gain in mpg.

Yep it must be the actual cost. I went on line and look at what we paid last year so all the fees etc are probably in there.

9.88 is the cost of energy, then there are fees which are dependent on region and distance from co-op or energy provider. The true comparative fee for power generation between providers doesn't include the distribution costs, since those aren't controlled costs.

If you wanted to compare with your neighbor, you'd include your entire bill, obviously. For a power company to compare their prices with those of another grid-charger, they have to use the inital cost of energy per unit, not inclusive of the other fees associated with delivery and maintenance.

In a Co-Op, the delivery and maintenance fees are basically non-negotiable. The only negotiable fee (as I understand it) is the base fee, which is price per KWh. The Co-Op has to negotiate between the residents and the larger power generation company, in this case, Penelec.

That was my mistake about liquid hydrogen, but the point is still valid that compressed hydrogen has a higher BTU value per volume than basic hydrogen (uncompressed).

I found a actual ICE car that was out to set a new hydrogen recorded.

New Page 1

The tank has a Type IV rating and uses a plastic bladder wrapped with high strength composite graphite. The tank has a water volume of 87 liters and is rated up to 3,600 psi. At 3,600 psi, the tank holds 590 SCF of hydrogen, which is equivalent to 1.4 gallons of gasoline. At 200 HP, this tank is emptied in about 5 minutes.

From my EFI calcualtor an engine making 200HP at 13.8 A/F with a BSFC of
.37 will consume 6.2 lbs in five mintutes with a cost of $2.50 in gasoline.

So it gets the equivalent of the same engine running on gasoline in lbs/HP-hr efficiency?

H2 is still more expensive per unit than gasoline, so I guess that wouldn't be considered viable, would it?

I think so LMAO!!!

196 cubic ft in a K tank cost 49.47 for the fuel.

590 SCF of hydrogen would then cost $149.00????

[Nerys]

huh my local gas suppler quoted me $18 to fill a k tank with hydrogen.

[Nerys]

so your comparing with a car that gets less than 5mpg ? your joking right?
