Bio-SNG - CNG Services

BIO-SNG FEASIBILITY STUDY – ESTABLISHMENT OF A REGIONAL PROJECTThe Bio-SNG approach accommodates a wider range of input feedstocks. It also converts the full calorificvalue rather than only part of the biodegradable fraction. This also means that for Bio-SNG, the majorityof the mass and energy flow goes to the outturn product (gas). In anaerobic digestion, the majority of themass flow is to the residual digestate 9 . For these reasons the Bio-SNG approach can be executed atmore substantial scale.Whilst technically feasible, this approach is less mature than anaerobic digestion. Transition fromaspiration, to widespread operating facilities and infrastructure requires a detailed understanding of thetechnical and commercial attributes of the full chain from feedstock supply through to delivery of gridquality gas, as well as the development of the first crucial operating facility which provides the tangibleproof of concept for roll out. The chemical and processing industrial heritage in the North East, its naturalgas and services infrastructure and its track record of innovation make it an attractive region to locatesuch a project.This report lays out the key regulatory, feedstock, technical and economic issues, as well as the practicalconsiderations of a pathway from current status to an operating project.9 Digestate is an important co-product from anaerobic digestion, and its beneficial use is vital as part of asustainable biological cycle. However it does impose significant constraints on scale and location of anaerobicdigestion projects.15
