摘要: A life cycle assessment has been completed of potential biogas infrastructures on a regional scale. Centralised and distributed were considered along with end uses Combined Heat Power (CHP) injection to the gas grid for either transport fuel or domestic heating uses. Damage orientated (endpoint) impact method identified that CHP 80% heat utilisation had least environmental impact, followed by use. Utilisation purposes via was found perform less well. 32% difference in transportation requirement between centralised have relatively small effect overall impact. Global warming impacts significantly affected changes methane emissions at upgrading stage, highlighting importance minimising operational losses.
