of progress today on getting more carbon dioxide supplies to chilled food distributors, and the meat industry. joining me now is professor stuart haszeldine, an expert in carbon capture and storage at the university of edinburgh. good to have you with us, professor. just explain for us to begin, at the very beginning, how the process works now. as we discussed with other gas, we know there are two fertiliser production plants which are responsible for giving the uk 60% of the c02 it are responsible for giving the uk 60% of the co2 it needs. when that co2 is captured there, who is that distributed around other industry? —— how is that restricted. distributed around other industry? -- how is that restricted.- -- how is that restricted. carbon dioxide is _ -- how is that restricted. carbon dioxide is really _ -- how is that restricted. carbon dioxide is really a _ -- how is that restricted. carbon dioxide is really a by-product - -- how is that restricted. carbon dioxide is really a by-product of| dioxide is really a by—product of those _ dioxide is really a by—product of those two — dioxide is really a by—product of those two fertiliser plants because what they do is use methane, natural -as, what they do is use methane, natural gas, as— what they do is use methane, natural gas, as an _ what they do is use methane, natural gas, as an ingredient, and chemically split that into hydrogen which _ chemically split that into hydrogen which goes to fertiliser and carbon, carbon— which goes to fertiliser and carbon, carbon dioxide, which they can either— carbon dioxide, which they can either but _ carbon dioxide, which they can either put into the atmosphere or sell on. _ either put into the atmosphere or sell on. so — either put into the atmosphere or sell on, so that is distributed from those _ sell on, so that is distributed from those plants by fleets of trucks and occasionally railway wagons, stored on site _
