If they can pull off half that range I'd be impressed.  Fuel cells are the future, much like fusion and flying cars.

I'd never be able to afford it, but damn do I want one.
That's a sexy vehicle.

/looks forward to seeing this tech make its way into more practical, 'affordable' vehicles.

The article doesn't discuss where they envision the hydrogen fuel as coming from.  Unless we're going to go into the inefficient route of electrolysis, which is using electricity to split water molecules, we're continuing to harvest natural gas and extract the hydrogen from that.  Both are problematic.  Why not just put the needed electricity directly into the vehicle?  Or, better yet, build a society that doesn't require each person to own a 2-ton mobility scooter?

It doesn't end well

"For example, the range on our vehicle is beyond 1,000 miles"

...or the distance to the nearest pothole."

/ Yes, I know, all "supercars" have really low ground clearance
// And snark aside, if they've actually got a good enough storage solution to bring hydrogen cars mainstream, more power to them

That's pretty good range for a rendering

Lithium is rare and not super friendly to mine. Batteries are still pretty heavy and storing energy this way is potentially more viable until battery tech further improves

Fuel cells will continue to use natural gas because it is cheap and easy.

Newer generations of batteries don't use lithium. The Dual Carbon batteries are game changers as are Sodium Ion batteries. The materials in batteries change over time. Early electric cars ran on lead-acid batteries which gave way the NiMH.

Or, some kind of wild expansion of mass transit.  The gallon-per-person-per-distance would be far better than even an electric car and cheaper to operate.  As the schedules currently stand, to take mass transit from my home to work, in central NJ, would take over eight hours.  I would love to take a combination of buses or trams.

A mid sized car will use about 5 kg of hydrogen to replace the fuel tank.  The current rate is about $14/kg so $70 to fill up.  Hydrogen has the advantage that is can be used in converted cars (like the natural gas conversions) or fuel cells but the fuel cell stuff is even more efficient.   Some existing cars use a few small cylinders each a bit smaller than a football that hold between 1 and 2 kg of H2 each.  There seem to be some people who have found a cheaper way to get hydrogen separated using a relatively cheap catalyst process that they claim is less than a $3/kg.  Other than their numbers getting very close to breaking the laws of thermodynamics, if they pulled it off, hydrogen will be a major source of fuel very soon.  At scale this is looking like a cost of $20 to fill up a Corolla (not figuring gas taxes).  It would be about $5 to fill it up with coal based electricity but this doesn't require $20k worth of batteries in the car and refilling is almost as fast as gasoline.
