hydrogen car

Definitely a better option than Electric vehicles...
Hydrogen car is the future. All EVs should be totally banned from the market. Knn EVs still need to queue, wait and charge for so long, drawing so much electricity from the power grid LPPL, not forgetting doing more damage to the environment mining for Lithium batteries.
When flooding, u will be in danger of electrocution.
Those with Tesla's shares better don't hold for too long... Unless they switch!!
EV loses out due to the charging time, nobody can sit there n wait couple of hrs!
Do you know the pressure required to liquefy those hydrogen? And even then, due to it's size, a portion of it will escape from the tanks. 500-700 bar. The energy to compress is enormous.
or freeze those hydrogen into liquid form is almost near absolute zero at -253deg C.
So you store it in gas form which is not very efficient use of storage.

To get green hydrogen, you need huge amount of power from electrolysis.
Or blue hydrogen extracted from lng.
Or grey from coal.

the 2nd gen mirai is pretty good looking.
It won't work as battery cars will dominate.
Fuel cells is only about 70% efficient. In case of mirai, hydrogen used instead of petrol, so ICE cars using hydrogen are about 50% efficient.
Batteries on the other hand stores about 95% of energy input and no need to build hydrogen stations as battery charging are connected to the grid. Infrastructure already in place.
NIO of China nailed the battery charging problem and high cost with battery replacement. That means you buy car excluding batteries. Only pay for charged batteries which takes 5 minutes to fit.
Only downside is cost of building battery swapping stations.
battery disposal after 6.9 years will be a problem. can trash it in prc as it’s a trashy cuntry but sg is too small. can offload battery waste in cecaland?
Let's all go back to horse riding...
The good side is NIO cars can be updated with new battery technologies. And older ones disposed or recycled by NIO as part of it's CSR. And electric motors are super reliable with less moving parts and may last for decades.
Tesla cannot do this. You buy you dispose. As batteries in cars deteriorate over time.
Producing, transporting, storing and Consuming hydrogen is almost as inefficient as current gasoline.
Factor in the hazards, technical difficulties, infrastructure etc, hydrogen is way less efficient than what we currently have.
Anyway you can see how people's rejection of hydrogen is reflected in the desperate way they need to lie to market it.
"Purifies the air". Hahaha

You need electricity to get the hydrogen.
How?

Hydrogen will ‘almost always’ lose out to battery-electric in German rail transport: train manufacturer
H2 and battery-powered train-maker Stadler warns that fuel cells need replacing every three years22 August 2023 13:27 GMT UPDATED 22 August 2023 13:27 GMT
By Rachel Parkes
Hydrogen trains are more complex to maintain than their battery-electric equivalents and are likely to lose out in the German market, where battery-powered trains will be suitable on almost every railway line, according to the Swiss manufacturer of both H2 and battery-powered locomotives.
