Hydrogen vs. Battery Electric Cars

7:00 Your graph is wrong.  The Lucid Air has 520 miles of range (EPA) but weighs about 2,375 kg.    Your graph stops at 400 miles, but if it continued on to 520, it would easily be up around the 4,000 kg mark; which the Lucid Air already proves to be wrong.  In fact, a lot of cars already prove this wrong.  It seems like the author must have assumed a specific aerodynamic drag coefficient and front surface area of the test cars, plus a specific energy density of the batteries.  Battery cells have improved since 2009.  Hence, even though you re-published this video, it's still misleading.

I'm not one to completely dismiss fuel cell vehicles.  In fact, I'd love to see a version that uses a smaller tank and fuel cell, but a larger battery; effectively a plug-in hybrid fuel cell vehicle, where electricity can be used for daily driving, and hydrogen can be used for long range trips.   People love to discount hydrogen due to its high fuel price, but most of them ignore that hydrogen and fuel cells haven't realized economies of scale yet; with predictions that Hydrogen prices could drop from their current ~$14 per kg down to as low as $1-$2 per kg.  The only way to do that is with massive scale.  The problem is, the more companies that transition to BEV production, the less likely it is for FCEVs to hit the scale of sales they need.
