Willow and miscanthus crops are being bred and engineered to burn more cleanly in power stations, as part of a UK-wide effort to make bioenergy a commercial reality. This project addresses a practical gap: biomass fuels vary widely in quality, and no single crop or waste stream works well for all conversion technologies—combustion, gasification, or pyrolysis. Without understanding how genetics, agronomy, and chemistry affect fuel characteristics, power plants and biofuel producers cannot reliably predict performance or avoid problems like slagging, corrosion, or low energy yield. If successful, the research could make biomass a more predictable and cost-effective part of the UK energy grid. It would help power stations co-fire biomass alongside coal, support small-scale heat and power units, and improve the efficiency of transport biofuels like biodiesel. The project also explores a “bio-refinery” approach, where biomass is used to produce both energy and chemicals, reducing waste and creating new revenue streams. Much of the work is fundamental science—studying the basic chemistry of thermal conversion and the genetics of energy crops. Past research in this area has already moved bioenergy from niche experiments to commercial co-firing; deeper understanding could unlock further breakthroughs in fuel handling, plant engineering, and sustainable supply chains.
View original technical description
Bioenergy is now becoming a commercial reality, ranging from cofiring in power stations, small units for power and/or heat, as well as transport fuels such as biodiesel. This SUPERGEN bioenergy project will continue to deliver the scientific background to the provision and utilisation of bioenergy, as well as innovative concepts for new applications. The research brings together growers, biologists, agronomists, economists, scientists and engineers in a unique multi-disciplinary team that will tackle the challenges associated with the further development of this renewable resource in a sustainable manner. The extended programme examines production and utilisation related factors that affect quality and suitability of a biomass fuel for different end uses, with a particular emphasis on the energy crops, willow and miscanthus, as well as more diverse fuel streams including residues and co-products. The work programme ranges from practical issues associated with fuel handling and preparation, to fundamental studies of genetics, agronomy and chemistry that affect both desirable and undesirable fuel characteristics. In addition, key engineering solutions for the successful development of biomass thermal conversion technologies are sought through (a) an understanding of the basic science in thermal conversion and (b) component and plant engineering issues. These topics are developed further in this renewal proposal through advanced engineering models complemented by experimental studies in a range of combustion, gasification and pyrolysis units.In addition, the scope of the project has been widened in this continuation to consider challenges in fuels and chemicals production from biomass, integrated with energy production in a bio-refinery approach.
