Hydrogen ran out

[oil pan 4]

I think the point of hydrogen fuel was to send people running and screaming towards battery based vehicles.
When people are required to pay the full cost of their own hydrogen, that will be the end of hydrogen poweredvehicles.

The hydrogen powered vehicles have around the same range as my leaf on a single charge. My leaf uses $15 to $20 of electrical power per month.
Every fill up on a hydrogen vehicle could run around $30 to $50 and only get you 100 to 200 miles of range.

Oil Pan, did you say elsewhere that you average about a thousand miles a month riding a leaf in the wind? That would be the equivalent of 5 - 10 $30 - $50 fill-ups, or anywhere between $150 - $500, and 7.5 - 33⅓ times as much as you pay.

Would the cost of hydrogen go down if it went mainstream? Do hydrogen systems break down faster than battery packs?

Hydrogen already is main stream. The oil industry produces millions of tons of hydrogen every year for hydro cracking of petro chemicals. It still remains difficult to store, transport and use.

The cost of hydrogen would likely go up if hydrogen went main stream since now almost all hydrogen is used to make other stuff. If hydrogen its self is the end product it would be add additional load to existing processes.

A fuel cell can supposedly last 30 to 100 years. The tech used in the Che y volt battery is probably going to allow the batteries to last at least 20 years.

H2O.... Our planet has a super giant supply of hydrogen, just add solar electricity and you get hydrogen by its self. Anyone saying hydrogen is in short supply is just wrong, very wrong. Approx 80% of the matter in the universe is hydrogen.

Sure, carrying a tank of it is not so easy yet, but landing on the moon wasnt easy either.

Making hydrogen from water is the most expensive way on earth to get hydrogen.
I just said the US oil industry makes millions of tons of hydrogen per year.

Electrolysis of Hydrogen is also very energy inefficient by the time you make a round trip through a fuel (fool) cell stack. Much better to just put the electricity in a battery(if we have enough batteries).

H2O is to hydrogen what CO2 is to gasoline.

It would be cheaper and more efficient to get hydrogen from gasoline than to get hydrogen from water.

Many folks claim to achieve some good results with the HHO generators, but I have never seen any claim of those devices being used as the only fuel source. It's usually fitted as a supplemental system, with those claims to decrease gasoline consumption. Anyway, had it been really effective, we wouldn't see anybody still using gasoline.

There have been a few yahoo's that claim to run their engine off straight hho, but they all have a few things in common, they won't let anyone even look at their setup and they all want a lot of money for their plans.
