Anaerobic Digestion - Biogas (Power, Transport, Biomethane Injection, CHP)
Particular caution should be used when projecting forward on recent growth rates, as the industry is starting from a low base. Deployment correlates closely (with an 18-24 months lag) with changes in government financial incentives, such as the introduction of increased Renewables Obligation (RO) support in 2009, and uncertainty over both the RO and Feed-in Tariffs in 2012. This would suggest that significant reductions in tariffs in 2014 will have a similar impact over time. Although growth has been good, generation is still lagging behind the government’s projections.
ANAEROBIC DIGESTION CONTEXT
l Unique in that eligible for all the financial incentives for power, heat and transport fuel
l PwC estimate that £576m was invested in the sector between 2010 – 2013 l In 2014, PwC calculate that an additional £122m was invested l Over the period 2015 – 2020, PwC forecast a further £1,919m could be invested in the sector (£m, Real 2012)

l Biogas can also be cleaned up and injected into the gas grid as ‘biomethane’. Green Gas Certification Scheme tracks sales of the gas to support green claims by end users
l Can use food waste, animal manures and slurries, residues from food processing and crops
l Solid outputs (‘digestate’) can replace mineral fertiliser, providing nutrients and improving soil fertility. Biofertiliser Certification Scheme certifies digestate so farmers can be confident in quality and safety
l Feed-in-Tariff is seeing dramatic reductions in support, particularly hurting smaller-scale developers
