It is good to see you again, Mr Hall. I want to drill down into a couple of issues. You mentioned animal transportation. If I were to be provocative, I would say that NFUS is arguing for weaker live animal transport regulations than those being proposed by DEFRA, notwithstanding the geographical challenges that you have outlined. How might you use the internal market act to allow—[Inaudible.]—or even challenge regulations that you see as undermining the needs and the interests of your members?

Thank you. Back to you, convener.

That answer perhaps addresses the question about the 80 per cent of natural gas that will still need to be used within the gas grid for blending.

I invite Mr Dalhuijsen to comment, to give another perspective on things.

Time is moving on. Mr Dalhuijsen, do you want to answer any of those points or speak about waste incinerators?

It helps a little bit.

I have another follow-up question. The Government’s “Update to the Climate Change Plan 2018-2032: Securing a Green Recovery on a Path to Net Zero” discusses the deployment of CCS technology in respect of energy from waste incineration plants. There are numerous such plants in Scotland. Can you comment on the economics of retrofitting existing plants, and on whether CCS could be deployed effectively at that scale for future energy production from waste incineration plants?

I will go back to Professor Haszeldine on that question.

I was just reflecting on the comments by Professor Haszeldine in the previous evidence session about the Government in effect requiring the oil and gas industry to store carbon emissions on a compulsory basis as a licence requirement, and I wonder whether Mike Tholen can give us the industry’s view on that. Specifically, given that there are 6.6 billion barrels of oil and gas in the North Sea, how much of that carbon can be captured and stored? On what timescale can that happen?

But how much of that carbon can be captured by 2030, given that the next eight years will be critical to climate change? Let us go back to the 6.6 billion figure. How much of that carbon can be captured through carbon capture and storage schemes and buried under the North Sea between now and 2030? What proportion of that—

I am sorry if I mischaracterised that. My question is, basically, who gets the hydrogen?

I have a quick question for Alan James. Last week, the UK Climate Change Committee said that there should be a cut-off point of 2023,

“beyond which efforts should be increased in other areas if commitments on CCS infrastructure ... are not secured.”

How confident is the industry that you will get that cast-iron guarantee by 2023 and that, as a result, we will not need a plan B?
