This does nothing for climate change, but does a lot for agriculture. What happens is that they use CO2 scrubbers to initially concentrate the CO2 which is then released directly into a greenhouse environment where the added CO2 sharply boost productivity.
This is actually a sound technology with plenty of operational history. With this it becomes possible to scrub CO2 at a power plant and to then actually pipe it to the customer.
Would be nice to pump heat as well.
