For anyone who thinks hydrogen is a good idea, please read this. There's another article I'm trying to find that goes into the many technical issues with hydrogen fuel, such as pumps icing up.
this is the article I was looking for
https://www.hydrogeninsight.com/transport/analysis-it-is-now-almost-14-times-more-expensive-to-drive-a-toyota-hydrogen-car-in-california-than-a-comparable-tesla-ev/2-1-1519315
There are problems with these articles, and it almost always comes down to scale. There currently isn't the scale and infrastructure to bring the cost of hydrogen to make it cost effective compared to pure electric. With time that could change if there is a will to do so.
But regardless, as I mentioned in my other comment, hydrogen has a much better use case in large scale transport. Trains and ships, for example, where volume isn't a problem and where the weight of batteries becomes untenable. This is, I think, where hydrogen will be viable.
How does the weight of fuel cells compare to batteries?
I can't find the exact figures, as it depends on battery range and battery tech. One study I've seen found a battery truck would weigh over 5000kg more than a hydrogen-electric version.
I've also seen figures of double the weight for a Li-Ion battery EV compared to HEV at ranges above 300 miles.
