With current electricity infrastructure, won't that completely saturate the grid and/or be problematic for people wanting to actually put the chargers somewhere? We're talking megawatts here, and (at least over here) getting a grid connection of more than a couple of hundred kilowatts means serious talks with the grid operators. Because larger max loads mean larger potential impact on the grid when your load suddenly…

Yes and no, 1200km charged in 10 mins is somewhere around 1MW of peak load. that's manageable and readily available using off the shelf distribution equipment, but it is a lot. The equipment is by no means cheap and large charging sites would almost always require upstream distribution and transmission upgrades, but this is something utilities are planning for. I suspect we'll also start to see on site energy storage to help offset the demand charges that these sites could see.

Earlier quoted context omitted.

You think the problem is just the CEO and not the corporate culture or its complacency and arrogance and now confusion now that it's no longer the darling of Wall Street/The Nikkei? It's yet another Japanese zombie corporation that's lost its way.

Revenue is vanity. Profit is sanity.

Many a large corporation had revenue growth even when the writing was on the wall for their business model.

Toyota has been going hard on this story, no surprise since they dug a grave of irrelevance by anchoring themselves to hydrogen for decades. Even when it was clear EVs were the future and interest in hydrogen was barely registering. Also no surprise that they have nothing to show except a "just wait 5 years!".

Would hydrogen make sense for really heavy vehicles like bus or truck, or even train?

I think for cars it isn’t the most convenient. But at the same time hydrogen would be cool if it works because it’s so abundant. And it’s pretty cool that the hydrogen cars exhaust water.

Now waiting for the catch here because this sounds too good to be true.

One catch would be the massive strain on the AC grid; with an EV consuming some 200Wh or so/km, 1200km equals a capacity of approx. 240kWh. 240kWh in 10 minutes translates into 1,44MW - for charging one car! (Assuming 100% efficiency.) The bottleneck when installing EV charging stations in many parts of Norway at the moment is simply getting the AC oomph needed to the right place. Our electrical ferries (much bigger…

This is likely how most charging stations with this power requirement will work too. They will have on-site batteries that are charged at a slower rate to help increase the overall charge speed. Charging stations aren't used 24/7 and this additional battery capacity can absorb day time solar power as needed.

> dug a grave of irrelevance

A grave of irrelevance so deep that they are the world's largest automaker and their net margins just hit an all-time high. Sometimes I do wonder from which planet these HN remarks are sent.
