Running a car on water via electrolysis

The technology works fine for sure. It's just not economic though and it produces more CO2 than it displaces.

Graham

CTL ?

Graham

What advantages ?

Electricity generation is ~ 35% efficient.

Hydrogen made by electrolysis is about 50% efficient.

Hydrogen burnt as a fuel in an ICE is about 25% efficient. Hydrogen burnt in a fuel cell is about 50% efficient.

Hydrogen fuel cell EV > ~ 8% efficent. Hydrogen ICE vehicle > ~ 4% effcient.

Graham

Maybe Brent forgot the 70s oil crisis ?

Invade or attack Iran and the USA can forget getting *any* Arab oil in the future.

Graham

Cite ?

And used in the US btw.

Graham

Inexpensive ? No way. They need expensive materials for the catalysts.

kW not kWh.

A lot more than 20 hp.

Graham

Where are the queues then ?

Graham

Now you're the idiot.

Graham

It's called politically inspired tokenism.

No, it's a monstrously bad idea since any hydrogen leaks can create a highly explosive atmosphere.

Like you mean *NEVER* ! The cost of hydrogen is linked to the price of energy.

Graham

You're absolutely right and it pollutes more too.

Graham

Electrolysing water is hugely energy wasteful.

To do it meaningfully on a large scale would require hundreds of nuclear reactors. I think I calculated once 500 1GW reactors to convert half of all US traffic to hydrogen.

Solar and wind power to make hydrogen ? Forget it.

Graham

That's the point. The numbers say we could be very close. There is no concise accounting by any agency. The USGS and EIA numbers are clearly a joke. How can you plan rationally?

Are you getting this?

You're right there Joe. Just the ability to reclaim their kinetic energy when braking makes them very attractive.

The other neat thing is that the ICE in a hybrid doesn't have to be sized for the peak power demand ( as when accelerating ) it only needs to be sized for the average power since the battery 'takes the strain'. Possibly no more than 20kW ( say 500cc ).

Graham

That does it. You are a crank. It is about energy and you make like it isn't.

Bye bye..........

Idiot. Coal heating value to wheels is the issue.

Yes, you are still an idiot........

LMAO !

You can't even control Iraq ! And that's already cost over $ 1 trillion.

Are you truly that mad ? All to satisfy your thirst for oil ?

Graham

An ERoEI of 1.3 meaning a net of one tenth of one quad?

Are you getting this?

Has anyone done this yet ? Where are these solar power stations ?

Graham

Gee, and the guy made like this will get fixed, 'La la la la!'
