You can use hydrogen for combustion engines?

Not sure if serious, but anyways:
>simply electrolysis of water
That's the catch. You need energy to do this, so what you're actually doing is storing energy in the form of hydrogen, think of it was a battery. You need to find an energysource that lets you produce hyrdogen from water.

I know that's the point of making the car a hybrid
making better use of the energy so it'll be worth it

bump

>>1208817
this must be a troll, so sage

>>1208914
Why?
I don't see anything wrong with my suggestion...

so where do you get the energy required to perform electrolysis of water? don't say petroleum

Hydrogen fuel cells motherfucker, have you heard of them?

>>1208925
Ok, OIL!

>>1208925
You won't make it yourself
Some other factory will and sell it to you
Kind of like gas station but with hydrogen instead of gas

>>1208944
guys come one, where's your sage??

hydrogen is expensive and hard to make and requires more money to store properly, cost becomes far too much of an issue

Protip: one of the most accessible sources of hydrogen is hydrocarbons, especially oil and coal.

Moving from gas and oil power to hydrogen power will do nothing to cut our dependence on fossil fuels.

>>1208983
It's why the Bush administration loved it. Provided very little competition for oil and its main source was the hydrocarbons that funded Bush

>>1208967
That's a goblin, not a troll.

>>1208983
herp derp, I do of course mean oil and GAS, though it can be extracted from coal too.

>>1208983
It will make driving more expensive which will force fat people to use bicycles.

>>1209002
No, it's a Boss Troll.

The problem being the source of energy that the factory would use. All options are rather meh. If coal, you might as well use a combustion engine. I doubt it would be possible to have enough nuclear power available. Fusion would work, but it isn't efficient enough yet.

Then there's also the material for the fuel cells. Currently platinum is used, since it is safe, but there's not enough on the planet. Some ceramic materials would surely work, but currently there are none that are as good as platinum.

Conclusion, fuel cells aren't currently a viable option, but most likely will be in the future.

Hydrogen is insanely easy and cheap to make on a large scale. You can make the systems on site at hydrostations. Think about it.

>>1209015
You don't need to store hydrogen as electric energy. Why not use it as combustible fuel? That would take the fuel cell out of the equation. You would need a hydrogen tank and a LN2 radiator.

>>1209030
>>1209018
It's far cheaper and infinitely less complex to simply use the hydrogen source as fuel instead. No need to manufacture specialized vehicles to use specialized fuel cells in specialized engines. You can burn the fossil source at a power plant and store the power in a battery to use in an electric car, or you can turn it into gasoline and use that to drive a bog-standard car.

Why can't you let this troll thread die??

>>1209073
I'm not a troll damn it
I wasn't suggesting we used fuel cells for the hydrogen, I was suggesting we used it for combustion
You know, burning hydrogen and making it explode inside the cylinders of a motor thus pushing them up and down instead of using gas

>>1209109
says the troll!

(on the off chance you really are this stupid: STOP POSTING!)

>>1209119
Why do you say I'm stupid
How is using hydrogen for combustion a bad idea?
Is it because you think its explosive?
Cause I have news for you, gas is explosive as well

>>1208919

I do, you're posting it on 4chan.

Get into a wreck with a hydrogen car, everyone dies if the tank is punctured. No chance of survival
