True. But it takes a lot of effort to make a competitive EV. The competition has optimized air and rolling resistance, battery chemistry, and battery cooling/management software.

It would have terrible range with the same footprint. Hydrogen has great energy density by mass but terrible energy density by volume. The tank needs to be huge (but it would be light).
Don’t they heavily compress the hydrogen with special tanks and compressors? Making it really cold, for example, makes it easier to compress.

Toyota has absolutely nothing for the EV age having bet the house on hydrogen and failing that just ICE. Now they are scrambling and making promises on research when they have nothing remotely to suggest they can do what they are promising, not even a prototype.

Making affordable EVs with a good range and fast charging is hard. Toyota' EVs are relatively expensive, and their batteries and drivetrain are mediocre.

That's nothing compared to all conventional cars.
1000 km battery, 10 minute charge? I'm suspicious for many reasons. If they can't build their prime hybrids — or even supply gas Siennas in Canada — I'm not very confident about their manufacturing in the mid-term. I hope I'm wrong.
For a 150 kWh battery, 10 minute charge to go from 10% to 80% SoC means charging at 600 kW or so. It would be pretty insane.

Judging from the fact their EV was losing its wheels, there's also the problem of handling the extra torque, although I can't imagine that would take long to fix if they care at all.

Not feasible on even 240 Volt AC at all, would have to be high voltage all the way to the charger as the cabling is unworkable. Its completely impractical otherwise and its going to require big changes to the grid.
Workable with a battery swap station next to a substation.

I would assume, but perhaps be wrong, that it would be liquid Hydrogen pumped into a vehicle's tank, and much like a tank of propane, the liquid expands back into a gas as pressure decreases (due to consumption). Hydrogen vehicles have the advantage of being refillable in minutes, much like petrol based vehicles - yet the only byproduct is water vapor, making them completely environmentally friendly. Hydrogen is also…
> I would really like to know more about why Hydrogen vehicles did not take off as much as electric. Lots of reasons. So, here's some off the top of my head. * Infrastructure - There's no hydrogen distribution system in place. Further, hydrogen is trickier to distribute/store. It's not like gas where you can just have a big empty metal drum that you fill and discharge. Consider, for example, that as gases expand they…
Methane will ignite when in concentrations of 4% - 17% in air, but with hydrogen the range is 4% to 75%. Hydrogen also has a higher flame speed than methane. (Boom!, not Whoosh!)
Given hydrogen's propensity to escape from containers these properties make it unsuitable for domestic uses.
I see way too many Toyota battery articles for a company that can barely put out an EV. They're all promises... in the future, they swear they'll beat everyone, but they just released a Lexus EV at $60k with 196mi range and 5sec 0-60.
They're trying to Osborne effect their competitors. Don't buy our competitors EVs, something much better is coming soon we promise...
[IBM salesman's wife]: All my husband does is sit on the end of the bed and tell me how great it's going to be.

They were supposed to have solid state battery cars and vehicles for the Tokyo Olympics. It was obvious that wasn't going to happen and it didn't. Toyota has been completely asleep at the switch for EVs which is baffling since they pioneered the hybrid electric vehicle. What's really strange is after having such a huge lead and hybrid electric vehicle, they have really crawled behind other manufacturers and producing…
It takes zero effort to make an EV. They are incredibly simple vehicles. People really need to let go of their EV fanboyism (and likely that includes Tesla fanboyism). In reality, if EVs were the future, Toyota would start making vast numbers of them in just a few years. The real issue is that BEVs are not cost effective right now, and show no sign of that happening anytime soon. Until then, PHEVs and hybrids make a…
In practice you are not:
- you need an entirely new software stack (the S-word makes car manufacturers break into sweat)
- you need an entirely new supply chain, or even worse for OEM-integration-addicted carmakers, build your own supply chain
- you need to secure a competitive priced volume battery source
- you can't just slap motors and batteries into an ICE frame. You NEED that last 50-100 miles that total system integration and design gets you in EV range
