Techno-economic modelling of the national UK food chain using the TIMES model (CSEF Centre)

Tell us about your work

My main role as a research fellow is to source, gather, assess and evaluate energy and financial data regarding the efficiency of current technologies used in the UK Food chain in CSEF at Brunel. I have been at the centre since its launch in 2013, and since then, have managed to collaborate work with various universities (including UCL, Birmingham, Harper Adams and Manchester) in the UK, research institutions within the EU (ENEA, SINTEF) and more importantly, managed to participate in DECC and BIS workshops in London.

The main aim of my research is generate comprehensive and traceable data and models in order to adequately advise government bodies about the consequences of current and future energy policies on the level of food and energy security in the UK. This work is being conducted by colleagues at UCL, and so far has been quite productive.

What were your previous roles?

I moved to the centre directly after completing my PhD at Brunel, dealing with energy storage in large lightweight buildings. I was appointed due to my competency in energy modelling. Being at the centre has allowed me to expand my modelling capabilities to different modelling methods, and I simply hope to keep growing in expertise.

What do you see as the key important area that needs to be focussed on to reduce energy demand and meet carbon emission reduction targets?

Being a commodity, the environmental impacts of food are heavily dependent on both the supply and demand side, perhaps more than other sectors. For instance, the elimination of meat and dairy consumption has been found to reduce emissions by up to 33%, but naturally this is not possible unless everyone becomes vegan – which is unlikely to happen. Hence the work I do, looks at both the demand sideĀ  (i.e. changes in consumption pattern, demographics, etc.) as well as the supply side (using more efficient technologies (such as CO2 refrigeration), and how these two are likely to converge. To my view, and hence the importance of these centres, It is unlikely that significant reduction in environmental impacts will be achieved unless both the suppliers and consumers work together to ensure a sustainable future.
