One way in which bioenergy production can be increased is through retrofitting, the addition of new technology or features to existing industrial installations. Retrofitting means often lower capital expenditure (CAPEX), shorter lead times, faster implementation, less production time losses, lower risks and therefore faster project development and increased market benefits. BIOFIT aims to facilitate bioenergy retrofitting in five industries: first-generation biofuels, pulp and paper, fossil refineries, fossil firing power and combined heat and power plants. First an overview will be made of existing options for retrofitting, and best practices analysed, to establish (both technical and non-technical) success factors. This will constitute the basis for two core project actions i.e. the development of 10 concrete bioenergy retrofitting proposals (2 each per industry) and the establishment of dedicated working groups for each industry (industry platform) to facilitate two-way dialogue. Both actions will be industry-driven, and focus on identifying and helping to solve actual – general and industry-specific – barriers towards wider market uptake. BIOFIT will give specific attention to generating information for policy development. Acceptance of bioenergy, both by the industries and by the general public, is key to the industries’ transformation towards sustainable bioenergy generation and market uptake. Research into acceptance factors is an integral part of project set-up. Key issues will be highlighted, and guidelines for industries will be issued. The BIOFIT consortium is a multidisciplinary partnership, with strong industrial involvement, broad coverage across Europe, and existing practical experience developing bioenergy retrofits. The expertise of the consortium covers all five target industries. BIOFIT consortium partners have wide networks in industry and industry platforms, ensuring relevance and transferability of all results.
