I thank my noble friend for that question, because he alluded to one of the key points about the future of gas storage—the Rough field—and what will happen with that in the future. He will know that there were suggestions that the Rough field should be used for hydrogen storage. That is now not happening, and the Rough field is available for quite a large expansion in overall gas storage. Having said that, we do not have enormous amounts of gas storage. On the other hand, we do have access to very secure forms of gas, albeit traded on the international markets, with the pipeline interconnectors that we have, the Norwegian gas supply that is freely available to us and, as I mentioned, with the development of LPG terminals in this country, we have the ability to land large amounts of LPG and to store it as well. My assessment of gas security would be that, although we do not have a huge amount of gas storage, we have, collectively, a pretty secure gas security arrangement. I just drop in the point that we are producing increasing amounts of biogas in the UK, which is beginning to come to a few percentage parts of the gas supply overall. Again, that is a homegrown, secure way of doing it. That I think means that, although we will have a future management issue of declining gas in the system—and there is much less gas going into the system now than a few years ago—we nevertheless have a pretty secure gas arrangement in the UK.
