Operators of a crop-fed biogas plant have watched energy output double in just six months following an overhaul of the digester biology.Based in Consett,County Durham,the 1 MW Generation X AD plant was operating at just 40% efficiency and was suffering from biological instability.To get an assessment,they brought in an independent service provider,Ben Jenkinson.”The AD plant was developed in 2015 and was originally commissioned on 100% maize.Due to the plant location,in an area where maize is difficult to grow,it was impractical to secure a long-term,reliable and affordable supply of the crop.It was therefore fed a mix of equal parts maize,grass and wholecrop cereal,”Jenkinson explains.
