Researchers from the University of Nottingham and CSIRO Australia have developed a pioneering combined milling and combustion performance model to improve the selection of low carbon fuels for power generation. Published in the Journal of the Energy Institute, the study evaluates the milling and combustion properties of five biomass types—pistachio shells, walnut shells, rice husks, palm kernel shells, and wood pellets. Currently, around 8.3 million tonnes of biomass is used annually for pulverised fuel (PF) combustion in the UK, which accounts for 21% of the global wood pellet market. This is dominated by wood pellets and wood chips, followed by recycled and waste wood, with other types of biomasses making up only around 1% of the total. The majority of the UK wood pellet demand is also met by imports, with the United States and Canada being the major suppliers.
