Summary

UCL has developed the UKTM model as commissioned by DECC. This model is intended to be used for future UK energy policies, as it incorporates the energy system with the wider UK economy. CSEF-Brunel aims at enhancing the food module in UKTM ranging from agriculture to consumption/waste. The project aims at altering each component in UKTM as follows:

Sectoral distribution technologies:

As this module accounts for calibration of the UKTM with DUKES data, this module is expected to remain unchanged from the already existing version.

Sector-specific infrastructure:

The food and drink sector will be incorporated into this module, in addition to the other sectors. The food/drink sector is expected to be incorporated in each ‘sectoral distribution’ area, in order to allow the incorporation of the food chain into the overall energy consumption of the economy.

End-use technologies:

This module will be created by CSEF to account for the technicalities and costs of specific technologies used by the food chain. Due to the wide variety of technologies available in food-chain operations, this module is proposed to be generated as shown in the figure below. However, the actual structure will depend on the level of detail obtained for each technology, and the overlap of technologies for the different ‘end-use demand technology’ groups defined in the figure below.

Demands:

The energy demands module is being disaggregated for different food areas, initially according to SIC2007, as shown in the figure below. The driver for the food chain is food demand, which is dependent on population growth, product mix and price. Hence, energy demand will also depend on the amount of food required by the economy. Initially, these demands can be exogenously input to the model, however, a complete model would require the endogenous calculation of both food and energy demands.

Therefore, we will also aim to implement either:

  • the MACRO module to the UKTM to account for changes in food consumption, labour and technology costs, or
  • variations in price and cross elasticities of demand of food products to alter food demand-mix for projected time periods

Furthermore, the resources module will be altered to include food waste as a resource, whilst the imports module will be altered to include food trade. The primary and secondary energy consumption, and GHG emissions of the food chain will be obtained as the aggregate of the food sectors. The aims in extending the UKTM are to:

  • obtain the influences of energy and food policies on the food chain energy consumption and GHG emissions, and;

identify the optimum (least cost and least GHG emissions) technology mix to satisfy energy and food demand, for different projected scenarios.

Highlights
