Abstract

Highlights: Expeditionary Campaign Infrastructure energy usage is predicted on an annual basis. Aquifer thermal energy storage is considered for the reduction of energy usage. The model predicts significant energy savings and a favourable financial payback. Asymmetric seasonal demands affect ground temperatures adversely if left unchecked. Abstract: A comparative study was undertaken to predict the energy savings associated with the employment of aquifer thermal energy storage in combination with a commercial water to air heat pump when used in Expeditionary Campaign Infrastructure against the climatic demands of Helmand Province, Afghanistan. Energy usage was predicted using EnergyPlus and the thermal response of the aquifer modelled using Processing SHEMAT based on predicted energy usage. The resulting analysis suggests a 22% reduction in fuel usage against an existing air to air heat pump with a CO2 reduction of 39 tonnes per annum. Although thermal stability of the aquifer could not be ensured without mitigation measures being undertaken, financially the analysis predicts a £335, 000 per annum fuel saving assuming that the fully burdened cost of fuel is $11.98 per litre thus offering a payback period of less than 2 years operation.
