Personally, if we're going to not pass on the environmental risk and liability to future generations, I don't see how we can be building nuclear, because nobody knows what to do with all the waste that's produced, and that certainly is a way of passing on that risk.

I just want to welcome the fact that you are focusing on green hydrogen as the long-term goal, but I'd be keen to understand what we can do to generate more excess electricity from both wind and solar so that we're not so reliant on having to use blue hydrogen for decarbonising our industries. And lastly, I wonder if you could tell us, in terms of the non-combustion processes that are emitting, what progress is the Government making on supporting industry to develop much more low-carbon concrete. as opposed to the stuff that's normally used? Clearly, we're still going to need concrete, but we need to have low-carbon concrete to build those bridges across our railways and rivers.
