Abstract:
On behalf of a UK-based upmarket retailer, Mitie Asset Investment (Mitie) has purchased two 4-engine updraft gasification combined heat and power (CHP) plants from Stirling.DK (SDK). The CHP plants are to be part of a trigeneration system delivering heat, electricity and cooling to provide a complete carbon-neutral energy solution for UK supermarkets. Each SDK plant will deliver 140 kWe and 500 kW of useful heating (600 kW total heating), using app. 320 kg of fresh wood chips per hour (800 kW input), operating 6,565 hours a year. The aim of the paper is to provide an overview of technical and economic benefits of utilizing biofuelled trigeneration systems in the retail sector. We expect that the largest gains will come from the utilization of heat in an absorption/adsorption chilling system to substitute cooling from electricity. To the authors' knowledge, there have been no previous applications of small-scale solid biofuel combustion systems for trigeneration in the retail sector. These two cases should provide valuable information on the commercial viability of small-scale biofuel systems.
