You could do most of your driving with a EV or PHEV using electricity. After the tax rebate a Nissan Leaf would cost you about $22k. A Chevy Volt, a few thousand more. And state/local rebates could take the prices lower.

If you’re an average 13,000 mile driver a 3kW solar array should produce all the electricity you’d need (for 40 and possibly a lot more) years.

13,000 * 0.3 kWh/mile / 365 days / 4.5 avg solar hours = 2.4 kW.

If you’re an average US household and use about 30 kWh per day then 7 kW of panels should produce all the electricity you use per year (and for 40+ years).

So, less than $25k for a ride. 10 kW of solar $32K ($4.59 US avg price and the 30% federal subsidy).

Let the grid do your storage and backup for now.

Half of your estimate and you’ll be producing what you use.

2) The Toyota FCEV has tanks as small or smaller than a 300 mile range ICEV? Please share the data.

3) Possibly. You do realize that a 3 minute vs. 20 minute fill up on a long trip will likely not mean any appreciable difference in arrival time? At least not enough to offset the higher price per mile.

6) Do some more math. Include the cost of electricity per mile.

2) Blatantly false. The new Toyota vehicles prove that.
3) 3 minutes for a complete fill up. And you can do it at home.
6) Do the math. $400 kit and water gets you fill up’s forever. Pay $40 a week for gas now? On week 11 you make money. That’s just with what we have today. As it gets wider acceptance. an H2 filling connection will become part of every household solar installation.

“2) Range and performance is equal to gasoline” H2 does not pack as much energy per volume/weight as gasoline. Range, unless tanks are very large, is less.

“3) Fill up times are equal to gasoline.” Perhaps they could be. Fill up times for CNG are slower.

“4) Fewer moving parts, less complicated engines” OK.

“5) Performance does not degrade with temperature, like electric” I’ve no information.

“6) You can make it at home” Inefficient use of capital.

Ford (their F250 TriFlex Fuel truck), Hyundai, Honda and Toyota all have had H2 cars, some for years.

H2 is coming and can’t be stopped. It is a vastly superior fuel.

1) It is clean. Totally perfectly clean.

2) Range and performance is equal to gasoline
3) Fill up times are equal to gasoline.
4) Fewer moving parts, less complicated engines
5) Performance does not degrade with temperature, like electric
6) You can make it at home

Costs are always an issue. At this point in time H2 fuel cell cars would cost about the same per mile as gasmobiles. We lose about half the energy in the conversion of electricity to hydrogen and then into kinetic energy. Plus that hydrogen infrastructure has to be paid for.

Since we don’t price carbon there would be no financial advantage for people to move to FCEVs.

We need to move away from oil. EVs cost about one-third as much per mile as gasmobiles.

Our move away from oil (and coal) will largely occur because renewables are so much cheaper. The fossil fuel industry will likely be able to block a price on carbon (in the US) for some time to come.

The real problem is resistance from oil companies whose world ends the instant that infrastructure is built.

Critical damage to this planet requires us to make the switchover, and since ALL renewable energy is local, the benefits of a total switchover to H2/Renewable are phenomenal.

Clean air, clean water, total elimination of the CO2 produced by man, ending the energy monopolies, no electric or heating bill – forever, efficient housing, no more pipelines, filthy tankers, wars for oil, massive oil spills, refinery fires, just to name a few.

Lessen Harmful Emissions

I have encountered people who question the cost of hydrogen as a viable storage medium. Especially for vehicles.

This idea is interesting. But unproven. And it certainly is not producing cheap hydrogen.

It might, but so far it hasn’t….

Hydrogen can be produced cleanly and hydrolysis is a catalytic — not a 1 to 1 storage system.

I do agree though it will be interesting to see if this proposed system become sufficiently economical. Of course we’ll still need cost effective and safe distribution and storage as well. Personally I’m betting on electrics, but I wouldn’t mind it being hydrogen that wins out either.
