My Lords, I have come to learn rather than to criticise or analyse in much depth. I was on the Select Committee on energy in the other place and I have tried to keep up to date with developments. I congratulate my noble friend on the fact that, according to his statement, we are the first in the world to go down this track.
My questions are really exploratory. I looked particularly at page 70 of the extensive documentation. First, I have a question about energy crops. It seems that if we are starting in a new area, the bringing together of waste collection is quite a challenge, whereas energy crops by definition are probably on a 12-month cycle. Therefore, the 50% limitation that is mentioned here, while probably the right strategy in the medium term, seems a bit of wishful thinking, certainly in the initial stages. You have to have energy crops to get the thing going.
Secondly, what is the estimated time required to set up any of these plants? Are we talking about a year, 18 months or two years? That is fairly key.
Thirdly, there is the question of the intermix of the gas provided by this route alongside gas from the North Sea. As far as I can see—I have not done an in-depth analysis—there is no reference to this. Is there complete compatibility or does there need to be treatment one way or the other to ensure compatibility in the mix of gases going into the grid?
There is another area that concerns me. Like so many others, I was previously in local government. How will we ensure that local government waste collections collect food waste and other waste suitable to feed these new plants? I do not know the proportions, but at this point in time we in central Bedfordshire are separating only recyclable and non-recyclable waste. I do not know what is happening in the rest of the country, and an update on that would be very helpful.
I thank my noble friend for taking this forward; it is crucially important. I will do my very best to help him on the journey forward.
