Thank you very much.
Mr. Keith, earlier, you were asked a question about the safety of CO2 capture and storage technology, particularly with regard to leaks. At the end of your answer, you mentioned that the technology itself seemed safe but that it was rather at the local level that problems may occur. Some experts will say that leaks could occur.
So, what kinds of technologies exist to fix any leaks, should any occur? What are the challenges? What do we need to focus on to improve the effectiveness of this technology, if necessary?
