Bill Nimmo

Professor Bill Nimmo is Professor of Energy Engineering and Sustainability at the University of Sheffield's School of Mechanical, Aerospace and Civil Engineering. He also serves as Head of the Faculty of Engineering Graduate School, overseeing postgraduate research student recruitment, training, and progression across engineering disciplines. His academic career spans over three decades with significant contributions to combustion engineering, energy systems, and sustainability research.

Bill Nimmo earned his PhD in Fluidized Bed Waste Gasification Processes from Leeds University in the mid-1980s, establishing his foundation in chemical and combustion engineering. His research interests span multiple critical areas in sustainable energy including biomass combustion, biomass gasification, anaerobic digestion, waste-to-energy conversion, corrosion studies in advanced combustion systems, and coal combustion/gasification with carbon capture technologies. His work bridges fundamental research with practical applications for cleaner energy systems.

His recent publications reveal a strong focus on fluidized bed combustion technologies, chemical looping combustion for carbon capture, biomass utilization, and advanced emission control strategies. The research demonstrates a clear trajectory toward developing sustainable energy solutions with particular emphasis on integrating renewable resources with conventional power generation while addressing technical challenges like agglomeration in biomass combustion and corrosion in oxy-fuel systems.

Professor Nimmo serves as Principal Editor of the prestigious Elsevier Journal FUEL (Impact Factor 7.5) and is an active member of the Fuel and Energy Research Forum Executive Committee, where he chairs the Environmental Division. He also participates in the Energy Institute Yorkshire branch committee and the EPSRC Peer Review College.

As a research leader, Nimmo has secured substantial funding with over £7 million in research grants as principal or co-investigator since 2009. His current portfolio includes projects funded by EPSRC, Innovate UK, BBSRC, Royal Academy of Engineering, and British Council, focusing on ultra super-critical fluidized bed combustion, anaerobic digestion, energy from waste, and knowledge economy partnerships. He has supervised numerous research students and early career researchers through the Energy 2050 Group.

Professor Nimmo leads research activities centered around the UKCCSRC PACT facilities for carbon capture processes, with particular emphasis on pilot-scale oxy-fuel combustion projects. His team operates advanced experimental facilities for biomass combustion, fluidized bed systems, and anaerobic digestion research, contributing to both fundamental understanding and practical implementation of sustainable energy technologies.
