I thank my noble friend, but a significant amount will still be LNG and I do not think that undermines my point. I know that my noble friend Lord Truscott has lots of experience, but I must admit that I was surprised by his analysis. Even if we are sceptical, it was a British geological survey, after all, which identified 1,300 trillion cubic feet of natural gas. If we take only 10% of that as capable of being extracted, which is a reasonably modest assessment, that is something like 40 years’ supply of the gas that we use—and we are being invited to say that we should not even consider using it.
My noble friend suggested that it was all about the current price of oil and gas. Of course we should take that into account, but as he was invited to say, is he seriously thinking that companies will invest in shale exploration without any prospect of return? I talked to companies recently about this and said, “Aren’t you deterred by the current price?”. They said no, because they do not invest at today’s prices. They are talking about a plan that is likely to take five years. I do hope that the House will support the government amendment.
On protecting groundwater, of course we should be doing that. Again, I have looked at this carefully. Apart from the fact that there has been very little evidence of methane contamination from fracking, we are talking about a six-inch pipe being drilled down. When it goes through the aquifer, which is at approximately 300 to 400 feet, multiple layers of steel and concrete contain the gas on its way to the surface and prevent it escaping into surrounding rock and groundwater.
What about the myth about the chemicals? We should remind ourselves that 99.95% is just sand and water and that the 0.05% consists only of approved non-hazardous chemicals, one of which is polyacrylamide, which is used for contact lens solution. We would be unlikely to use that chemical for a solution like that if we thought that it was seriously hazardous.
I am just as concerned about the environment and the water supply as the noble Baroness, Lady Jones of Moulsecoomb, but I am also concerned about those who, frankly in my opinion, misapply science and deliberately distort data rather than convey to the public the facts and the independent assessment, which is what this House should be doing. On those grounds, I hope that this House will overwhelmingly support the government amendments.
