Centre for Research into Energy, Waste and the Environment
To generate and utilise affordable electrical power, propulsion and heat with minimal environmental or social impact, and to optimise industrial processes.
Over 80% of current UK energy demand is provided by hydrocarbon fuels. The Centre’s focus is to provide efficient, reliable heat and power generation, whilst moving towards a lower carbon economy.
Research work involves mitigating the effect of carbon-based heat and power generation (coal, gas, oil) systems, for example, through carbon capture technologies, or de-carbonising fuel supplies, whilst developing and improving the efficiency of renewable power sources such as marine and biomass-derived power. Chemical energy storage, for example, in the form of hydrogen or ammonia, and the research problems these raise, is also within the group’s remit.
The utilisation of traditional fuels and the introduction of new energy technologies require careful management of the various risks and hazards posed. Whilst energy may be considered on a supply/demand basis, this needs to be controlled by a systematic (management) process.
It is essential to analyse the impact of current and future energy utilisation in terms of health, safety and environmental management. The Centre specialises in the characterisation of hazards from traditional and alternative fuel sources, energy surveys and audits for high energy demand leisure centres and hospitals, and waste-to-energy schemes. Current estimates are that the UK’s Municipal Solid Waste (MSW) could produce up to 12% of our electricity requirement.
The Centre’s work also focuses on the application of new fuels and propulsion technologies for the transport sector, primarily automotive and aerospace. The transport sector is perhaps the most challenging area in the shift towards a sustainable energy economy, as it is still currently increasing its CO2 emissions, in contrast to the industrial and domestic sectors.
In order to enhance the understanding of energy systems investigations are undertaken into fundamental fluid dynamic and thermodynamic processes using new mathematical techniques and the development of novel laser diagnostic and experimental techniques.
