Moving on from biomass, we told about converting grass to gas. Bioethanol is probably the most efficient way of doing it because one can have a crop that can be produced three, four or five times a year depending on the variety, but one needs a critical mass of 200 ha to 300 ha for production. It is not something that one can bring the product very far to by use of anaerobic digesters. I presume that will be dependent on the value refits that would be applied. which will determine the economic value.
