This statement was authored by a number of key geological experts and ZEP members in response to a recent publication by Ehlig-Economides & Economides 2010 which sought to demonstrate that CCS is not technically or economically feasible, based on a supposed lack of underground CO2 storage capacity. ZEP believes the E&E paper to be a serious misrepresentation of the scientific, engineering and operational facts surrounding CCS and have published an open rebuttal.
