Zero-emission vehicle technologies boil down to two options: battery electric and hydrogen fuel cells. Currently, battery electrics like Tesla’s vehicles and Chevy’s Bolt EV are dominating the field, as battery prices fall and range increases. Yet according as Bloomberg reports, auto industry executives are still apparently in love with hydrogen over batteries:

A KPMG survey last year found most senior automotive executives believe battery-powered cars will ultimately fail, with hydrogen offering the true breakthrough for electric mobility. That’s what Japan is banking on—Toyota Motor Corp. is making a big bet it will triumph over batteries.

Of the almost 1,000 officials polled by the Dutch advisory, some 78 percent said hydrogen cars will prevail because their tanks can be filled in minutes, making recharging times of 25-45 minutes for battery options “seem unreasonable.”

And yet this supposed advantage of faster charging time is eroding away, as super-fast chargers are being developed that could give an EV driver 200 miles of range in just a few minutes. And given that hydrogen stations are few and far between, what benefit is a faster charging time if it takes you 20 minutes to find a station?

What this survey tells me is that 78 percent of auto executives are not following battery technology very closely. Which I suppose presents opportunities for companies like Tesla to continue to do well in the market, if the rest of the industry doesn’t catch up soon.
