DECC appointed SKM Enviros and CNG Services Ltd in 2011 to undertake a review and analysis of the Anaerobic Digestion (AD) biogas and biomethane costs and technology characteristics in the area of combustion for renewable heat/electricity generation as well as clean up/upgrade for injection to the grid (biomethane to grid) and use in transport. The underlying purpose of the study was to support ongoing policy developments where AD is a
pertinent technology through the development of a database on biogas costs and build rate
assumptions that are consistent across all three sectors where biogas can potentially be used –
heat, electricity and transport. The study builds on DECC?s existing database (and other external studies) on the characteristics, costs and potential growth rates associated with the uptake of biogas and biomethane injection across the heat sector while also reviewing the technology characteristics for electricity generation to ensure consistency of assumptions.
