Re-burying the world's carbon emissions might seem like a logical solution to global warming. But it seems to only work in a very limited number of places.
A working paper released by the Carnegie Mellon Electricity Industry Center entitled "Implications of generator siting for CO2 pipeline infrastructure" discusses the issues regarding the geographical locations of power plants, their fuel, their loads, and finally, where (if anywhere) the CO2 they produce will be sequestered. It also addresses the costs associated with transportation of the fuel, electricity, and CO2, with some scary implications.
Not only that, these pipes have to be under high pressures to keep the CO2 at a supercritical fluid state, requiring a lot of energy and equipment, not to mention pumping stations along the way. To add insult to injury, the pipes will, like those in the arctic, disrupt animals' ranges and migration routes. At least if the pipes leak, we're not contaminating the environs with oil or flammable gases. There will just be a small dead zone will where everything dies from lack of oxygen. It's all very exciting stuff.
