You need electrolytes (salt) to electrolyze water. Might as well use sea water.

There are plenty of other problems with hydrogen energy, though.

This is not correct. All commercial electrolyzers need very pure water as a feed to the system. PEM and SOEC electrolyzers use the ultrapure (industry term) water directly, while alkaline electrolyzers combine it with potassium hydroxide. Using sea water will very quickly result in non-functional equipment.
