But who pays for the hydrogen pumps – the fuel company, the OEM [Original Equipment Manufacturer], the government – is not clear. Europe should look at Asia; it’s a good indicator that you can make into a business case. South Korea has 43 stations with a target of 500 for 2030; Japan has 100 with 800 planned for 2025. Asia will be a driving force for hydrogen storage.”
Will Hydrogen cars be a viable thing or just a stop gap until electric cars really match current ICE vehicles
>>14224222
Well you can use hydrogen for fuel cells, so that's kinda nice.
>>14224477
Wouldn't an ICE on hydrogen be more practical?
BMW and Mazda have done it already
>>14224526
ICEs are horribly inefficient, a fuel cell powering an electric motor should be more effective.
>>14224547
Except for the fact they use a shit load of rare earths to work. Inefficient as they are, they are a proven technology.
hydrogen is most likely the future.
batteries are hugely polluting.
>>14224526
Yeah probably. The point is you can do either one with the most prevalent element in the universe.
>>14224526
ICE is only more practical because of the energy storage capacity of fossil fuels.
ICE are ~40% efficient compared to say ~90% efficient electric motors, but the storage density is much higher for the ICE's fuel, so you have a much larger operating range in spite of its low efficiency.

...That's all already exploded
>paying for literal fumes
>drinking it
>>14224646
>shit load of rare earths
and catalytic converters don't?
last I checked we've come up with better alternatives to platinum for fuel cells anyways.
obviously there are lots of other issues preventing hydrogen from being the new gasoline, and it probably never will be, but that one is a bit of a cop out.

>baiting this poorly
>>14224973
I'm not baiting. See the point is, hydrogen is all already oxidised in the form of water and in that form can't provide anymore energy because to provide energy hydrogen needs to bond with oxygen and form water. the only way to extract hydrogen from water is electrolysis (pic related) which is inefficient af. Also, h
ydrogen storage is hard because the atoms are small and will fit in the smallest hole, not unlike your dick
This shit will never work because there is no hydrogen.
There are no naturally occuring hydrogen resources like there are with oil and shit. You got guys like >>14224833 who point out that hydrogen is the most prevalent element in the universe, but it doesn't exist in any concentrated form that we can reasonably extract.
Hydrogen has to be manufactured. You can do water electrolysis like >>14225134 mentioned, but the majority of hydrogen is made through a process called steam reforming (https://en.wikipedia.org/wiki/Steam_reforming).
But both of these methods use an external input of energy to create the hydrogen, and that external energy inevitably must come from fossil fuels. Steam reforming is directly using natural gas. Electrolysis requires electrical energy, which (when we're talking about a large enough scale for hydrogen to be used to power a significant portion of cars in a country) comes from fossil fuels at some point.
For every unit of hydrogen energy you make, you need to expend more than that amount of energy in fossil fuels.
So at the end of the day, even if you get your hydrogen engine or fuel cell working optimally, you're stuck because you have no hydrogen without fossil fuels.
i really don't get hydrogen cars
the entire premise is "EVs dont have enough range yet"
nigga batteries are getting better every fucking year are you saying by the time your hydrogen shit has rolled out everywhere batteries won't be better?
>>14225348
>and that external energy inevitably must come from fossil fuels.
Solar and wind power has been shown to be sufficient for a home charging station.
