Dr Scott’s research is focussed primarily on carbon capture and other processes for the abatement of CO2. This includes detailed investigations into specific technologies, with a large effort on processes which are based on gasification, combustion and thermochemical cycles, as well as more general process and reactor modelling and sustainability assessment. Recent work has looked at combined gasification and metal oxygen donor processes (often called chemical looping combustion), in which the oxygen for combustion comes from a solid oxygen carrier (usually a metal oxide) rather than air. Dr Scott's research in this area goes from the understanding and development of the materials, through to lab-scale testing and process modelling of the scaled up systems. He also works on the modelling of carbon abatement technologies, from the reactor scale through to the process flow sheet and the wider system scale. This has led to work on Lifecycle Assessment of Biofuels, including those which make use of novel biological systems (i.e. algae).

Research

Dr Scott's research is focussed on the alernative ways of using solid fuels, which reduced their impact on the environment. In recent years concern has grown about the use of fossil fuels and the effect of the CO2 they produce on the climate. Biomass and biofuels could be potentially carbon neutral, but there are issues such as land area and lifecycle CO2 emmision which limit their contribution. Fossils fuels will continue to supply the majority of the world's power for the foreseable future. Ways of mitigating their impact include capturing the CO2 ready for sequestration. Research in this area includes using alternative oxygen carriers (i.e. solids) to burn fuels, rather than air, in a process known as chemical looping and capturing the CO2 using solid sorbents.

A second strand of work aims to model fluidised systems. In these systems complex two-phase flows of particles and a gas exist. Aside from a fundamental interest in granular flow, these system are often used for to process solid fuels, e.g. gasifiers or combustors.
