Your post makes no sense.
Yes it does. You....
In other news, a gas replacement digression — I noted this on CCS:

Double the £ to build, but it doesn't comment there on the process price. Pretty awful process up to now to get a solid product.
With only 30 plants worldwide it doesn't look attractive, but may provide a wedge on the production pie chart in future.
Shoving it back underground again as they describe doesn't feelvery satisfactory, but it's not as potent a greenhouse gas as methane which it replaces. We've been doing it for years to pressurise gas/oil reserves.
No idea on costs of production withthe CO2 remover, or how much it would reduce gas-burning plants' carbon footprint - they leak like sieves. Like, really horribly. Methane is 100+ times as bad as CO2 immediately, though taken over 100 years it's "only" 25x as bad.
Here's a page with a lot of leads, some illusory, but hey:

With more CO2 burying established, it could be used for the products of non-green hydrogen, which range from blue through grey, turquoise, black and avocado bathroom. More coloured wedges on the pie chart, to come?
At the moment we're paying wind farms to not operate, when we don't need the power. Assuming we're to multiply the wind/solar production as we're told, then a lot more intermittently unwanted power production has to be a by-product. That begs the question of whether it would be worth using said power to store green hydrogen. Then if you go that way, it's apparently advantageous to generate H2 at the wind turbine and pipe the gas.
At the moment, making the hydrogen from splitting water is 65-80% efficient., but the round-trip is
unimpressive, at
hopefully 50%. Redox
flow batteries promise a better round- trip efficiency. The vanadium they use, is mostly found in - you guessed, China and Russia, though some elsewhere. OTOH you can't use batteries on a big plane, probably.
All options have high R & D costs, of course.
