As the car industry’s largest hybrid pusher, Toyota says it is better positioned to just buy credits to close the EPA gap rather than “waste” money on BEVs, its CEO said.
Obtaining hydrogen from water is much more energy-demanding, and the efficiency of the entire water cycle (water electrolysis, hydrogen transportation, electrical conversion) is extremely low compared to just charging batteries.
It wouldn’t. Hydrogen production from any source is extremely power intense. Especially so from water. The amount of energy wasted on hydrogen production is easily offset by battery production and recycling. And that’s not even accounting for hydrogen tank production, which is another hell hole.
Renewable energy doesn’t have a tap, you either use it when generated or don’t. If there’s an excess now it can be used. But yea hydrogen fuel may be a waste or not I don’t know. But to say theres an energy shortage everywhere is just not true.
I never said it does. I did say for example there are areas that generate hydroelectric/wind/solar power that otherwise would be effectively wasted. Hydroelectric power can control the flow partially to bank it for later, but thats not the case with the other two.
Hydrogen would be cleaner in the long run, too, wouldn’t it? Since you wouldn’t need to mine lithium for batteries and such.
Yes but where is the hydrogen coming from? Also hydrogen cars are less efficient than battery powered EVs.
Water.
Natural gas, primarily.

Water, I think? I think the hydrogen is less of an issue than the hydrogen fuel cell though.
Only 10 more years to go!
Unless we improve the efficiency of both electrolysis and fuel cell conversion to about 98%, we won’t beat the batteries.

Not the mention the overwhelming vast majority of hydrogen today is produced from fossil fuels and not through electrolysis.
Let’s not kid ourselves, anyone advocating for hydrogen as fuel is defending the continued existence of the fossil fuel industry.
There are plenty of places with abundant green energy, and abundant water. As for the tank yea, but idk if it’s worse than lithium
The energy is only abundant until the moment you start wasting it. Hydrogen fuel is a waste of energy.
Renewable energy doesn’t have a tap, you either use it when generated or don’t. If there’s an excess now it can be used. But yea hydrogen fuel may be a waste or not I don’t know. But to say theres an energy shortage everywhere is just not true.
Renewable energy doesn’t mean infinite energy.
