My Lords, this amendment sparked an interesting debate in Committee when the noble Lord, Lord Redesdale, moved it. I was pleased to hear the Minister confirm then that biomethane was considered a renewable. The noble Lord, Lord Teverson, was right to stress the part that biomethane could play in meeting our CO2 reduction targets. We have already had a debate on the role of heat as regards renewables, and biomethane plays an important part in that. I should be interested to hear more from the Minister about what work is being done on the feasibility of injecting methane directly into the gas network. As I understand it, there are still some technical issues to be worked out. I hope that he can indicate when these are likely to be resolved.
