What are the byproducts of converting seawater to hydrogen and oxygen?

Hydrogen is seen as some sort of saving angel in the energy issue.
Producing the hydrogen is a bit of a problem though. It takes a lot of
energy to produce it. It has a pretty low volumetric energy density.

Interestingly enough, a gallon of gasoline contains more hydrogen than
a gallon of liquid H2 - it's a great way to store hydrogen.

But to the problem at hand, a somewhat practical method of producing H2
would be to electrolyze it, using Nuc power. The electrolysis plant
would probably be set up near the ocean (let's not even talk of fresh
water production - just ask the folks on the left coast about fresh water)

So now we have an extraction plant that is powered by an unpopular
power source, and has one big nasty polluting byproduct.

Or we can use the other methods of generating H2. Of course, they cause
as much pollution producing the fuel as if we just used the fuel in the
first place.
