It's also a by-product of gas production. If hydrogen is produced from seawater using renewable electricity then it could be considered renewable.

Its still a finite resource. Just like oil and gas. Lots of it….

We will run out of fresh water long before we would run out of sea water. Plus the ice caps are adding to the sea water daily.

If being used to produce hydrogen/oxygen which will be used to run internal combustion engines or fuel cells (both react the hydrogen back with oxygen, producing water as a result), then yes.

To be fair, hydrogen can also be produced from natural gas (95% of it in the US) which is not renewable. But from seawater and solar panels, heck yes, it's renewable and seawater will never run out.
