Hydrogen vs. Battery Electric Cars

BIASED! 
-no mention of cost of installation of fuel stations
-no mention of how much energy hydrogen will take if we were to produce the same amount of H2 that provides the same range as battery
-no mention of how solar energy saves more energy in case of battery
-Also, will a hydrogen tank last forever?, if no , then for how long will it last? and what will be the cost of getting it replaced.
Also, lets change the places of battery and hydrogen cars in terms of number of cars and fuel stations on street...what will be one refill costing...is the fuel cost efficient?

A better field to research upon in order to conserve energy and provide optimum efficiency is the improvement of batteries.

your whole argument was based on how hydrogen cars will be in future, but it should have been compared with how batteries seem to develop in future
