My research vision is to pioneer cost optimal innovative ways to decarbonise residential and industrial energy systems, through the deployment of low to negative carbon technologies for electricity and heat provision. My previous track record is centred on three major themes. The first is modelling of low to negative carbon technologies, the second theme is the development of quantitative decision-support frameworks for industrial energy systems design and the third is creating pathways to commercialize technologies and clean industrial energy systems.
Under the first theme, I develop novel analytical models of primary technologies (combusting fuel/ harnessing renewable energy), and waste heat recovery technologies (i.e. technologies producing useful energy from heat rejected by primary technologies). The models are capable of estimating the useful energy produced, and highlighting the parameters and variables required for techno-economic assessment of technologies. The models have been published in High Impact journals like Applied Energy, and applied to real case studies through collaborations with manufacturers.
Under the second theme, I develop novel graphical and mathematical optimisation frameworks capable of sizing, selecting, and operating technologies in domestic, and industrial energy systems. The graphical techniques integrate renewable energy, and waste heat recovery technologies using the temperature-enthalpy diagrams of industrial process streams. They were applied by industries under the Efficient Energy Integrated Solutions for Manufacturing Industries (EFENIS) project sponsored by the European Commission, and published. Another innovation is the graphical techniques applying them to recover additional energy from industrial processes, which have reached the maximum potential for heat recovery set by Pinch Analysis and Total Site Analysis. Some of the Mathematical optimisation frameworks developed by me are based on a multi-period mixed integer model. The novelty is the use of finer time resolutions to represent technology characteristics and energy demand data. I developed the optimisation framework used to quantify the impact of macro-distributed energy in the UK, under the Energy Technologies Institute MACRO-DE project. This framework was implemented in a software tool, currently used to support post graduate research and teaching at the University of Manchester.
The third theme is focused on quantifying how innovations in systems, policies and business models can increase the market share and adoption of strategies to decarbonise industrial process heating. Strategies include reduction in energy demand, increasing energy supply efficiency, fuel switching (including to hydrogen and electricity), and CCUS (where applied for flue gas capture).
