To ask the Scottish Government how many anaerobic digestion projects there are, and what targets have been set for the development of projects over the next (a) five and (b) 10 years.

Based on research recently commissioned to support the development of a Bioenergy Action Plan for Scotland, there are currently a reported 38 biogas to CHP sites in Scotland (excluding those at sewage treatment plants). Of these sites, 16 are waste fed and 22 are farm fed. These plants have a reported capacity of 30.8 MW utilising 866 kt of feedstock.
There are also a further 12 biomethane injection sites, of which 2 are waste fed and the remaining10 are farm fed, utilising 761,000t of feedstock to produce and estimated 188 MW gas.
We do not currently have a specific target for anaerobic digestion. However, the technology remains part of our diverse approach to renewable energy and decarbonisation. We recognise the role that anaerobic digestion may play in decarbonisation within Scotland, especially within the whisky and agricultural sectors. Scoltland's Energy Strategy, published in December 2017, sets a target for the equivalent of 50% of the energy required to meet Scotland’s heat, transport and electricity consumption to be supplied from renewable sources by 2030.
