Toyota’s chairman doubles down on his electric car skepticism, forecasting that EV adoption will peak at just 30% (fortune.com)

Akio Toyoda, Toyota Motor’s chairman, has never been a huge fan of battery electric vehicles. Last October, as global sales of EVs started to slow down amid macroeconomic uncertainty, Toyoda crowed that people are “finally seeing reality” on EVs. Now, the auto executive is doubling down on his bearish forecast, boldly predicting that just three in 10 cars on the road will be powered by a battery.

…

“The enemy is CO2,” Toyoda said, proposing a “multi-pathway approach” that doesn’t rely on any one type of vehicle. “Customers, not regulations or politics” should make the decision on what path to rely on, he said.

The auto executive estimated that around a billion people still live in areas without electricity, which limits the appeal of a battery electric vehicle. Toyoda estimated that fully electric cars will only capture 30% of the market, with the remainder taken up by hybrids or vehicles that use hydrogen technology.

Erm, no buddy. Everyone's entitled to their incorrect opinion, and this one's a doozy.

How much big of a tank of H2 do you need to effectively equal the energy capacity of a lithium ion pack? If the tank needs to be reasonably sized, how high is the pressure? How do you ensure hydrogen embrittlement isn't a problem on both the tanks and the transport pipes/storage tanks? How does pressure correlate with exfiltration?

Flying wires is a walk in the park, especially competitively.

A 700 bar tank will store more than energy than a similarly sized li-ion battery.

As an energy storage system for cars, the problem is already solved. People are just repeating the same anti-progress rhetoric that was used against battery cars.

700 bar?? 10000 pounds/in^2??

No, you've unfortunately lost your grip.

We've been doing it for over a decade now. It is shown to be safe.

No thanks. I'd much prefer electrified mass transit. I'm saying this as a former manufacturing engineer, there's quite a bit that can go wrong with cyclically pressurized vessels in subtle ways that are difficult to non-destructively evaluate.

This is not the path forward for anyone but heavy industry.

Then you are just being old and outdated. It is totally safe.

I understand your point, and disagree. Are you qualified to really understand this issue, or an opinionated enthusiast?
