You can now, but it doesn't scale that well if electric car usage increases 10-fold for example (which is still a very little fraction of total).
It scales better than green production of hydrogen does

I think it’s precisely that; with electric, there’s no special product to sell you. With hydrogen, or ethanol, the old oil and gas companies can more easily pivot into simply selling another chemical product. With electric cars, the oil and gas companies are like cable TV in the age of the internet; their days are numbered, and they fear it like nothing else. (Also, governments have nothing to levy special taxes on i…
Asian countries like Japan, Korea and China are the ones who are still pushing hydrogen tech. None of these are big oil producing nations so the conspiracy theory does not make sense.
Big companies such as Shell are pushing Hydrogen via something called the "EU green deal". This while Shell (and similar) do not expect hydrogen to be produced via green methods for 15+ years. They push the EU to "subsidize" hydrogen (and other things), to basically get loads of money from people in an indirect way.
This was e.g. reported via the journalists at ftm.nl. They're probably unknown to most people here, but loads of their findings resulted in loads of issues for the government (scandals, fraud, etc).
Hydrogen fuel is still a fossil fuel byproduct right? I’m not sure what the point of this is. It sure doesn’t seem like a green technology at this point.

Tesla record is over 1000 km, so at this point I'm not sure why anyone is interested in hydrogen for personal vehicles over electric.
We were getting 1000km between fill ups (60L tank) on a family road trip in a bog standard 1.8L gasoline (!) Ford Mondeo, seating 2 adults 2 kids and with trunk loaded to the brim and A/C running on full. Really difficult to be excited or impressed by these "records". Both Tesla and H2
The record is not the autonomy by itself, but is about getting the same autonomy for 35-70x less money and potentially 0Co2e emission.

I doubt that. I've got a Leaf that I've had for almost 2 years (i.e. lots of rubber on the road), and I'm not going back. Judging by the number of Teslas I see driving on the road every time I'm out, I don't think other people are going back either. This is in Minnesota too, with very icy and cold winters. I've seen that commonly brought up as an anti-EV talking point, but it's empirically wrong.
> I've got a Leaf that I've had for almost 2 years Isn't the Leaf known for poor battery temperature management? This causes the battery perform way worse over time than other EVs. A battery performing way poorer over time is a common fear that I've noticed. If someone notices this and doesn't know it's unique (caused by manufacturer not doing enough) then I'd expect some Leaf-owning people to dislike EVs. The huge p…
Every Nissan dealership around me has free Leaf-only supercharging, and there's also a few superchargers around the Twin Cities that just cost the price of parking (e.g. ~$1/h). Other than that, every Goodwill has a supercharger that costs some actually metered amount of money.
Since “tank” isn’t a unit of measure, I suppose anyone could trivially break the record with a larger tank. From the article: > The Nexo consumed 6.27kg of H2 For comparison with the other production H2 cars: Toyota Mirai: 5.6kg Honda Clarity: 5.0kg Seems like a promising technology. My understanding is that the current blocker is infrastructure. It’s hard to pressurize up to 10,000 PSI, so many facilities are only a…
Also the infrastructure for electricity basically is there, mostly needed are plain outlets at all long-term parking spots. And of course, one can charge an electric car from your own solar.
This is at 66.9 km/h (40 mph) in order to greatly increase its range due to lower drag compared to normal highway speeds. As a comparison a Tesla Model 3 got 975km (606 miles) at 40 km/h (25 mph) [1]. I can't seem to find any range tests at a similar speed as the Nexo. I found an EPA dyno test for the Model 3 at 77 km/h (48mph) for 708 km (440 miles). The Nexo and Model 3 have similar dimension and weight and price,…
The Nexo is much less aerodynamic than the Model 3. One is an SUV/CUV, the other is a low sedan which looks like wet poop. The Nexo has more frontal area and a higher CD. And the Tesla is known for rigging its EPA tests for higher, but illusory, numbers.
> “I was constantly checking the Nexo’s efficiency readout to maximise the distance I was getting per kilogram of hydrogen. I found that by using techniques from rally driving, such as looking as far down the road as possible, as well as tips I have learned from my dad for driving a truck efficiently over long distances, it’s actually possible to go way beyond Nexo’s official range.” Anyone have some insights on this…
I drive a Prius, it's a skill to drive efficiently. The main tip: do not use the gas pedal if you're going to brake soon anyway. Think of the brakes as wasting gas, then you'll use the brakes sparingly, and the safe way to do that is by not accelerating unnecessarily. Just think of this. You see some kid in a red sports car at a stop sign. They blast off quickly, then after one block they brake hard for the next stop…

10,000PSI hydraulics are rapidly becoming cookie cutter commodity parts. Once you have the supply chain for all the little crap that nickles and dimes you the rest is a lot cheaper. Having industry expertise at working at those pressures really has a huge multiplier effect on everything else. Building a system to plumb stuff from A to B at a pressure nobody uses is expensive. Calling up a sales rep and asking for sli…
How many people would be ready to drive a hydrogen bomb?

Model Y will blow the doors off the Nexo in performance due to much larger electric motors.
