In theory, yes. All you need is a tank of OH- and H+. When the two combine to make H20 (water) they give off a charge that can be harnessed to power a motor, a lightbulb, any electric device you can think of with the only byproduct being water. The problems, however, outweigh the benefits as of today. Pure hydrogen is extremely combustible, so improper containment could be disastrous. Also, you have to get the hydrogen in the first place, which requires energy itself, and there is an efficiency issue between how much energy you put in and how much you get out of it. Finally, hydrogen requires a much larger container than a battery or a gas tank.
Once these issues are worked out, hydrogen is going to be everywhere
Burn it in oxygen, causing heat which you use to convert water to steam. The steam drives a turbine that generates electricity.
