The Techno Economic study of UK Biomass Preprocessing Project (TEAB) was commissioned by the Energy Technologies Institute and delivered by E4tech, CMCL, PSE, Imperial College Consultants, Black and Veatch, University of Sheffield and University of Leeds between 2016 and 2017. The TEAB project compares the costs, efficiencies and GHG emissions of biomass supply chains with and without significant pre-processing, to assess whether and how pre-processing steps can benefit UK bioenergy supply chains. Ten supply chains were selected for modelling and analysis in the project, two of which generate heat, and eight generating power. These are compared in groups according to their shared conversion technology, and all the chains are able to use a blend of Miscanthus and woody feedstocks (from 0-100%). Available here are gPROMS and Excel models describing bioenergy supply chains and project reports. Further README files in the models and reports sub-directories describe the contents further.
