Amidst California’s ongoing efforts to promote environmentally friendly transportation and the changing landscape of hydrogen fuel infrastructure, Toyota has announced a dramatic rebate of up to $40,000 off MSRP for the 2023 Toyota Mirai.

How about building up the count of fueling stations, and stabilize the supply of hydrogen first?

PS: OP appears to be a bot or paid hydrogen supporter.

Oh boy, what a comment section.
"You're not green!"
"No, you're not green!!"
...
Wow.

How about... this is absolutely not environmentally friendly?

[–] halfwaythere 3 points 7 months ago (2 children)

How? Why? Care to elaborate?

Hydrogen, even if you make it 100% via electrolysis with solar power, is extremely inefficient. In the order of regular ICE cars inefficient. You piss 2/3 of the energy away while having the complexity of a BEV plus additional hydrogen on top. It is worse in every way except range. Unlike batteries, filling up H2 at the fuel station is not getting faster with every generation. Unlike batteries, the range does not increase with every generation. Unlike batteries, the price does not go down sharply. Unlike batteries, the longevity of the fuelcell is shit.

Fuel cells are far more efficient than ICEs. Refueling times are already comparable to that of an ICE car. Fuel cells can easily last the lifetime of the car. Range increases with every model. This is anti-progress and anti-green nonsense. You're pretty regurgitating corporate propaganda, either from the oil industry or from battery companies.

Hahaha, more efficient that ICE? 70 % hydrogen production 70 % storage 70 % fuel cell Leaving out everything else, where does that get us?

Fuel cells last 100'000 miles. Simply calling that "like if the vehicle" is absurd.

Anti Green is pissing away 3x as much energy to make sure stuff stays the same.

[–] [email protected] 1 points 7 months ago

All steps can approach 100% efficiency. It is not much different than how a battery car works.

Fuel cells have already been test to 30,000 hours in real world settings. We're easily looking at million+ miles in certain circumstances. This is plain Ludditism to think that reliability can't be achieved.

Interesting. From what I've seen most of the tech that is used or being researched to produce hydrogen using electrolysis ranges from LTE (low temp) the least efficient at 70-80% to HTE (high temp), PEM (proton exchange membrane) and others using chemicals range ,from 70-90% efficient. You are correct in saying that the current cost constraints is the cost of the electricity being used. However with the amount of energy and the effects of strip mining processing and environmental effects. Hydrogen has just as much potential if not more as a future alternative to ICE.

Oh and according to Toyota on their Miria hydrogen vehicle it only takes ~5 mins to refuel.

Thanks for elaborating. It opens the discussion and understanding of potential mindset against this tech.

Making hydrogen is one step in the chain. Not the whole chain. 0.7 x 0.7 x 0.9 is only 0.44.

Last time I checked most of the hydrogen available in the US is produced from petroleum.

[–] Zeritu 4 points 7 months ago

Not just the US. There is essentially no green hydrogen on the world market, most of it is methane based.

[–] [email protected] 0 points 7 months ago (3 children)

Then you are repeating an argument from the oil industry. To them, all green vehicles are secretly dirty, and therefore you must always buy an oil powered car.

[–] Zeritu 1 points 7 months ago (2 children)

The oil industry has been rooting for hydrogen cars as their favourite alternative to combustion engines as most hydrogen is produced from fossil energy carriers. It's the oil industry's backdoor to remain the mobility supplier as methane based hydrogen dominates the market and will remain cheaper than green hydrogen unless the whole world agrees on proper taxes, which it won't. Hydrogen cars are emission free but hydrogen isn't. And while the same can be said for electric cats, the shift to renewable energy sources is already happening there and the higher efficiency already makes BEVs more environmentally friendly than ICEs, unlike hydrogen cars.

[–] [email protected] 3 points 7 months ago (1 children)

The same is also happening with hydrogen. We are shifting towards green hydrogen. People who claim otherwise are repeating the same anti-green rhetoric used against BEVs.

[–] Eheran 0 points 7 months ago (1 children)

What green hydrogen? Where?

[–] [email protected] 1 points 7 months ago

You're clearly stuck in the past. Green hydrogen production is rapidly expanding. It is the new solar or wind boom.

See my comment here in this answer to someone who just asked for arguments instead of making shit up.

[–] [email protected] 3 points 7 months ago* (last edited 7 months ago) (1 children)

You can make it 100% with fossil fuels and it would still be greener than a gasoline or diesel powered car.

[–] Eheran 0 points 7 months ago

How so? And why compare it to stuff that needs to go instead of the more and more widely available alternative?
