You need to see it as removing the carbon generated by industries that can't be powered by clean energy, not removing carbon generated by polluting electric facilities.
Ship transportation will probably never be converted to battery power, so running wind farms just to remove the equivalent quantity of carbon released by ships from the atmosphere is a net positive.
What? Green hydrogen seems very likely as an alternative for shipping.
I think air/spacecraft are the harder problems to solve.
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.
Yes it doesn't involve carbon capture, I was just replying to the comment that shipping needs carbon capture because of the fuel it uses. You don't need carbon capture if you change the fuel source which is entirely feasible for shipping.
