Dr. Fiona Thorne:

The only place where we have started to talk about that is within the biomethane working group in terms of the development of a biomethane strategy, so it is being talked about within that sphere. In terms of ongoing research that we have at the moment, it is not something we have looked at. However, in terms of the future research agenda and particular research grants that we have in at the moment, it is on the to-do list. It is something we see as a research gap regarding acceptability and the issues that are there in terms of gaps.
