Hydrogen fuel cell cars were supposed to be the future

Hydrogen fuel cell cars were supposed to be the future.

Now it's battery powered cars all of a sudden?

Do we not realize that batteries wear out fairly quickly?

hydrogen fuel cells are far more advanced and effective, but the infrastructure to fuel them simply doesnt exist - it would cost tens of billions to set up even a basic network. Electricity grids already exist, however.

Its less efficient, but its more manageable.

>Invent system that is low maintenance
>Invest system that is inherently redundant
Be a capitalist country and pick the obvious

There's a variety of reasons for why which concept is better than the other including but not limited to . Also "wearing out quickly" is a certain problem, but on the other hand keep in mind that people have a yearly competition to get through all of australia with limited supplies.

for instance. These """cars""" aren't really fit for public use, but they show what's technically do-able at this point.

Bitch you can't just ignore the efficiency aspect. Also we still have a big problem about storing hydrogen - it's the smallest known molecule and therefore goes through even the biggest fucking metal containments. If you gave out hydrogen cars to the public it would be a matter of weeks till the first dumb asses ignore the big fucking warnings about putting the car in a ventilated space and decide to have a smoke in their garage effectively blowing their shit up.
And at this point the public is FUCKING SHOCKED how dangerous this evil new technology is and ban it while proceeding to shoot each other.

Which one is redundant and which one is low maint?

b-but muh mining stocks and chemical companies!!
(((batteries are awesome)))
wanna buy some lithium?
cobalt?

>Guy blowing himself up by smoking near a fuel cell car

This guy doesn't know what he's talking about

dont talk shieet dude

and it would also blow up the house next door
BUT the trick is to not have H2 gas in a tank
...there are other ways

this

Battery electric and CNG (if you need some serious range) are gonna be the future. Infrastructure for hydrogen just isnt there but electric and natgas lines are everywhere.

I guess the hindenburg explosion was an inside job then.

that was different hydrogen you numbskull

They just say it to get money from the government. 50-60k for a car. What the payment at 1k a month yeah we all can afford that. It's a con

You owe me a fucking keyboard. Tea everywhere.

10/10

Hydrogen cells in cars and hydrogen gas in big balloons ok

poorfag detected, get off channer

Oh, shit. You were being serious. So which one doesn't use molecular hydrogen but uses deuterium or tritium?

ones a liquid the other is a gas any first grader knows this

There were three options. And gaseous or liquid state depends on pressure and temperature. Or don't you Boyles?

P is the pressure of the gas, V is the volume of the gas, and k is a constant, I get that but hydrogen is flammable in a balloon but safe in a car numbnut

Too bad ars won't ever run solely on ocean water. There's a resource we haven't even begun to tap into.

>hydrogen is flammable in a balloon but safe in a car
Why? Because it's contained, compressed and in liquid form? The Hindenburg burnt because hydrogen leaked and was ignited. In a car, if hydrogen leaks and is exposed to a flame or spark (of which there are many potential sources in a car) do you think there will be a different result?

the ballon was made of silk fabric I dont think a car will use silk fabric , cars run on gasoline which is highly flammable so your point is void and for that reason I wont be investing in your Hydrogen cells wrapped in silk fabric ok

Hydrogen cars don't work because just like CNG the energy density is crap and would require a huge tank to hit an industry standard 400 miles range. Electric just finally achieved that. That and producing hydrogen is no cheaper or greener than electricity, requires wild scifi cells with weird doped polymer materials that are even less easy to produce than high density batteries (unless you literally want to go the compressed liquid route lol *boom*). CNG is just as dirty as gasoline (cleaner than diesel lol u europoors), farts out just as much CO2 and requires a much less safe storage and transportation infrastructure. Believe you me lots smarter people than user have though about these things and there's a reason the whole world has settled on gasoline/diesel/and a little electric for transport.

Not sure if troll, or just incredibly stupid?

Go to bed, Hyde.

what about wind farms on cars ?

>cars run on gasoline which is highly flammable
Actually, liquid gasoline is inflammable. The vapour is a whole different matter; a bit like hydrogen

And, in case you're scientifically ignorant enough to doubt that, have a look here

ccohs.ca/oshanswers/chemicals/flammable/flam.html
>Flammable and combustible liquids themselves do not burn. It is the mixture of their vapours and air that burns. Gasoline, with a flashpoint of -40°C (-40°F), is a flammable liquid.

Problem is, hydrogen is more energy intensive to manufacture, and it's incredibly difficult to store. Hydrogen is obviously really explosive, but also readily evaporates out of tanks, since it can slowly pass through the metals in its gaseous state. That's why they tried to make hydrogen, double-walled fuel tanks with a vacuum between the walls, to help reduce heat transfer, to reduce evaporation, etc.

Nobody wants a car, where the fuel tank boils off in a month on its own, right?

I'd be curious to see some redox batteries in the future. The current ones are really bulky, but it's liquid energy storage, reasonably safe, efficient, can be stored, etc. Look up vanadium redox for example, it's nifty shit.

How about solar farms on cars

Hydrogen is water so that is safe til it vapours ignite too

thats what i meant

>all of a sudden
Why do people use this fucking ignorant phrase?
Have you ever seen 1/2 of a sudden?
What the fuck is a sudden?

Just use the adverb Suddenly. Goiddamit it.

>Hydrogen is water
Stopped reading right there. Such ignorance doesn't deserve a serious response

>What is H2O

>What is H2O
One of the most deadly chemicals known to man. Science has gone too far.

seawater

only in its vapour form
