That's not an answer on net zero. It's an answer to delivering affordable energy, potentially, but it's not an answer to net zero.
Now, what the IEA says is that the electricity sector will be the first to achieve net-zero emissions, mainly because of the low cost, widespread policy support and maturity of an array of renewable energy technologies. Electricity renewables are going to make up 90% by 2050 in the IEA's analysis. It's hard for me, I suppose, to take altogether seriously the role that natural gas has to play by 2050 if I'm looking at modelled costed numbers from the IEA and the answer back on your end on whether there's a business case is to say, “But we don't know.”
