The document discusses how anaerobic digestion (AD) can support local authority waste plans. It summarizes presentations given by a panel on the topic, including Alan Douglas from Cleanergy, who discussed Cleanergy's technology for combusting contaminated biogas to produce cleaner gas for energy production. He noted barriers to further AD development like disorganized feedstock collection and the need for long-term feedstock contracts. The panel explored how AD can complement large-scale facilities to optimize output, and how government policies could help encourage more investment in the sector.

Small scale distributed generation using AD
biogas, landfill gas and biomethane.
Stirling Engine technology.
Cleanergy’s GasBox can combust
contaminated gas enabling cleaner gas to
be used in larger scale spark ignition
engines for more efficient energy
production.
Complement large scale AD to
optimise output.

Policy
Implications

The World outside Westminster does not
work in 5-year Parliamentary cycles
RHIs have less than 10m to go, yet no
announcement is forthcoming about what
happens after 31 March 2016 – blocking
investment and deferring decisions
Incentives are reducing yet AD
technology is not becoming materially
cheaper, unlike solar and wind

5. Barriers to Further
Development

Feedstock collection remains relatively
disorganised and long term contracts
are hard to secure
Institutional capital seeks long term contracts
from “creditworthy” entities for certainty of
downside protection
What will AD feedstock sources look like
in 5 or 10 years’ time?
Will there be enough? Other
renewables markets have seen huge
changes in the quality and quantity
of feedstock over time
