Green Hydrogen doesn't involve carbon capture. It's sourced from clean energy in the first place. I hope we do see it produce fuel cells that can be used for shipping.

It's unfortunately "Blue" or "Grey" Hydrogen that the fossil fuel purveyors are pushing to make themselves look like they care about the environment, though. Non-green versions do involve inefficient attempts at carbon capture. If you see someone talking about carbons and hydrogen, they're not talking about Green Hydrogen.
