Reply to comment by Bournvitta2022 in Overhyping hydrogen as a fuel risks endangering net-zero goals by filosoful

Except that hydrogen takes 3x times more energy to make than charging a car directly. Also difficult to transport and store compared to just using the grid.

Also vehicles will be much more expensive to refuel and service than pure EV from a fundamental architectural point of view. Dead end tech.

Really, cost of EV was also high initially. Also you need to take into account the environmental effect of mining for raw materials in large scale plus recycling is a nightmare for now.

Hydrogen once scalability is achieved it would be cheaper to produce. It's just abt figure out material that can transport hydrogen like piped CNG.

Also for heavy TRUCKs hydrogen makes more sense.

Maybe we can have Battery for cars and hydrogen for industrial use and transportation.

But unless you count the first EVs a hundred years ago, hydrogen cars have been around for a lot longer than modern EVs. We had a hydrogen car push in the 90s or something and there was a lot of public and private investment into building a hydrogen distribution infrastructure. But the cost never fell. When the first modern EVs started coming around, they were already cheaper.

Yes but for countries like Japan and india. Hydrogen makes more sense even if expensive as long as cost is lower than IC engine.

Self reliance and also japan has a reactor that produces electricity as well as hydrogen at cheap cost. It's just a prototype but its promising.

It only makes sense in Japan because Toyota lobbied the government for heavy hydrogen subsidies.

It's only competitive if government pays the difference.
