It is a big concern in the oil/gas industry that the carbonation-induced corrosion of the concrete-covered steel casing or tubing in underground Carbon Capture and Storage (CCS) may lead to gas leaking and even an environment pollution disaster. To reduce such a safety risk, the carbonation degree of concrete in the CCS project must be detected or monitored, and the corrosion of steel casing/tubing should be inhibited in time. In this paper, Mg was investigated in comparison with Al and Zn in simulated concrete pore solutions (SCPSs) as an intelligent anode that may be used to detect the carbonation degree of concrete and protect the steel in the carbonated concrete. The results showed that Mg could be more sensitively activated and its anodic current efficiency could be improved by carbonation, acting as such a smart anode in carbonated SCPSs. In a practical CCS project, the intelligent detection of the carbonated concrete corrosivity and the protection of the steel casing in the concrete may both be realized by using such a smart Mg anode. While the Zn and Al could not act as a smart sacrificial anode since they were not sensitive to the carbonation and they could not provide sufficient cathodic protection for the steel in the carbonated SCPSs, either.
