+reddir A key concept to understand about this process is that it does not deliver the CO2, or any other gas at cold temperatures. It cools the gas until the CO2 freezes, separates the CO2 as a solid, then used the cold gas and CO2 to cool down the warm gas coming in the front end of the process. The gas coming in and going our are at about the same temperature and this makes the cycle much more efficient than a traditional refrigeration cycle like your AC.
Now if we can convert the co2 to a fuel, that would be even more awesome. Could this make coal viable as a clean energy source? Is this technology in use anywhere yet?
Yes, such the conversion from CO2 and water into liquid fuels is possible and has been possible for a long time. Over the past couple of years the process has become a lot more efficient though. So they estimate that we can get such fuels for 55 to 200$ per Barrel depending on what carbon capture technology is used and depending on how the fuel is made. There are companies that are already mass producing such fuels. There's ETOGAS in germany which has a 6MW plant that produces Methane. There's a plant in iceland that produces methanol (capable of producing 5million liters per year), there's a company called carbon engineering. Their pilot plant is capable of producing a barrel of fuel per day and they are currently scaling up production and they want to go on the market in 2021.
For a Gas Power Plant, it is great to create a combined LNG Regasification and CO2/NO/SO2 liquifcation air separation unit (RC-ASU)
How much does it cost to cool the exhaust to such low temps?

Approximately 80x the output of the powerplant.
That seems quite smart.

Wow nice
and what do you plan to do with all the dry ice? send it to Mars? Removal without storage route is pointless.
Just dump into deep sea and the sea pressure resist phase change from solid co2 to gas sea pressure is huge😁😁
