Re: [Phys-L] carbon wars

Liquifaction (with appropriate counterflow heat exchangers) may be the best bet for sequestration.

The depth of water needed to keep it liquid is surprisingly little.

Maybe a deep oceanic trench would make an appropriate storage facility.

(A recent Press Release from a Canadian firm http://energyblog.nationalgeographic.com/2014/10/02/worlds-first-full-scale-clean-coal-plant-opens-in-canada/ brags about the liquefaction - but a closer read shows that most of the liquid will be used to extract oil from the oil-sands in Canada.)
