Batteries Comparing to Hydrogen Fuel Cells
The advantage of hydrogen as a fuel for electric vehicles is that it can be charged faster than batteries, in the order of minutes equivalent to gasoline cars. Also, the higher energy density than batteries means that it can drive much longer ranges and pack more energy in the same space than battery packs.
Hydrogen: The next wave for electric vehicles? | McKinsey
Battery electric vehicles exhibit higher overall fuel efficiency as long as they are not too heavy due to large battery sizes, making them ideally suited for short-distance and light vehicles. Hydrogen can store more energy in less weight, making fuel cells suitable for vehicles with heavy payloads and long ranges.
