No surprises here Battery-electric vs. fuel cell vehicle: Which is greener? Quote: "In terms of overall costs, researchers found that battery electric vehicles are better than fuel cell vehicles for reducing emissions.

However, fuel cell vehicles are likely to be significantly more expensive than battery vehicles for the foreseeable future. Another supposed benefit of hydrogen – storing surplus solar energy – didn’t pan out ".
