Maybe for long distance transport hydrogen makes sense, because you can have a big tank and CO2 impact is lower than gasoline/diesel, but this will require incentives/subsidies from the state to make economic sense.
What is the appeal of a hydrogen car vs an eletric car? The range appears to be similar, but being able to charge at home is so much more convenient.

Most people can't charge at home (because most people live in multi-story houses in a bigger cities and don't have a garage to charge in), so refueling in 2min at a gas station still has appeal.

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…
I have an acquaintance who has made a substantial fortune from energy focused startups (including a battery tech one) and is now working on another hard tech startup and they are very critical of hydrogen as a fuel. I’ve had superficial conversations with them about it but could never get a sense of their fundamental arguments. Is hydrogen a non starter or are they just protecting their investments with FUD?
It's not quite clear from the article, but is this a stock Hyundai Nexo or was it modified to add more fuel tanks? The stock range of the car is 413 miles or 664km, so how exactly was this new record achieved?
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…
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 slightly modifications on an existing product line so it can be used with your product is pennies by comparison.
Isn't driving on a tank full of hydrogen like super dangerous?

It depends on how you define convenient. Hydrogen can be refilled quickly, in minutes, like a conventional liquid fueled car. If there were a network of hydrogen filling stations then driving, especially long distances, would be similar to driving a liquid fueled car.
