Pitch
Pipe Carbon Dioxide to Antarctica where it can be frozen and sequestered.
Description
Summary
A proposal has been made by Ernest Agee, Andrea Orton and John Rogers to sequester carbon dioxide snow in Antarctica. I think it might be better to pipe in carbon dioxide rich gas collected at power plants than to extract the low concentrated trace gas from the atmosphere. A new process for extracting energy out of coal called Coal-Direct Chemical Looping (CDCL) can provide seperated CO2 gas as an end product.

What actions do you propose?
Who will take these actions?
Where will these actions be taken?
What are other key benefits?
Removing CO2 cuts acidification of oceans.
Sequestering in Antarctica would be less risky than sequestering underground. Leakage of high concentrations of CO2 present a hazzard.
What are the proposal’s costs?
It would be a huge pipeline project. While a lot of new aspects might need research, it should be a straight forward pipeline project.
Of course it is contingent on the Antarctic CO2 snow sequester proposal.
