I was rather enjoying my right hon. Friend's contribution. I agree with all the points he made. Teach-ins were fashionable in the 1970s, but I am sure that the Opposition could benefit from a teach-in on this issue given the contribution we just heard.
I join my right hon. Friend in paying tribute to the officials who have worked on, and helped in, this incredibly complex policy area, and I also pay tribute to my right hon. Friend for the work on this issue that he did as an Energy Minister, and that he continues to do. He understands its international dimension, and I assure him that we will work with other countries to develop this technology. I have already talked to Secretary Chu, the US Energy Secretary, about how we can co-operate on our learning about CCS.
