Ironically, at least last time I checked 1-2 years ago, the Long Range Model 3 weighs less than the hydrogen Mirai and has more range.
Doesn’t matter what theoretical weight of hydrogen is when you have so much overhead the battery version weighs less! this is because:
1) hydrogen must be compressed. The compressed tank has to have high margins so it’s safe on the road. That means a much heavier tank than you might think
2) the fuel cell itself is expensive and weighs a lot!
3) fuel cells are MUCH less efficient so the useful energy isn’t what you think it is. That also means a lot of heat needs to be rejected which means:
4) heavy radiator (whose cooling also compromises aerodynamics), air filter and handling, you still need a lithium battery in there to handle regenerative braking and bursts of power, a bunch of high pressure hydrogen-rated valves which aren’t lightweight, etc.
May as well look at the weight of electrons in a battery as just look at the weight of hydrogen gas in a hydrogen car...
