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.

I just hope one of these never has a high speed crash.

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

They are filter feeders at the bottom of the ocean.
