Facts & figures

摘要

There has been a lot of talk recently about carbon capture and storage (CCS) but very few facts. This is not surprising since no one has actually built and run a large plant.rnEstimates, however, would be informative. For a start, could someone give us all an estimate of the overall system efficiency of a typical plant?rnThe total energy used (excluding the energy used in construction) involves mining the coal, transporting the coal, useful energy produced, wasternheat in the cooling water, CO_2 capture, liquifying the CO_2, transporting the liquid CO_2 to the site of injection and pumping the CO_2 into the bedrock.
