98% of H2 is made from fossil fuels because cracking water is
very expensive.
H2 is already expensive when reformed from natural gas - you can expect to pay 20-30 cents per mile to travel in the most advanced, fuel efficient H2 vehicle out there.

H2 made via electrolysis is a bit more than 3x that cost. Are you ready to pay $1 per mile to drive?
Of course, price generally declines with volume, so we could expect those numbers to come down if H2 were more widely adopted. But there is a thermodynamic floor on the cost of H2, which means that it will never be cost-competitive with pure electric vehicles.

And then there's the complexity issue. As a former fuel cell engineer, I understand better than most how complex and finicky proton exchange membrane fuel cell systems are. They are easily poisoned, they're prone to freezing, they have long startup times, they require high-speed, expensive electric air compressors, and they have complex valving and sensors to ensure safe operation.
Purely electric vehicles simply do not have these problems. A battery and a motor is about as simple as a drivetrain can possibly be. EVs will always be fundamentally far simpler than FCEVs, which translates into a lower upfront vehicle cost.
You have no answer to these problems.
I suggest you stop furiously responding here and instead consider your biases, and reevaluate your position. Batteries are so much better than H2 for transportation on just about all fronts that the two are not even close to comparable. H2 at this point is a malicious distraction being foisted on the general public by oil companies attempting to stay relevant, and governments engaging in sunk cost fallacious thinking. The sooner fuel cells for transport (and H2 for heating) are relegated to history's dustbin, the better.
Oh, and as for your assertion that electricity sans nuclear and hydro is 85% fossil fuels... that's true... and irrelevant. 40% of electricity generated in the US today is renewable, and that number grows steadily each year. We would be absolutely foolish to use that electricity to crack water, compress the H2, transport the H2, and convert it back to electricity in fuel cells, losing 65% of the energy in the process, than simply using it directly via batteries. Come on man! Discard the propaganda, separate your emotions from your positions, and think for yourself!
