Abstract

The drive towards net-zero carbon emissions has prompted many industries to alter the way they operate. The agriculture industry is responsible for a large proportion of the UK’s greenhouse gas emissions. Thus, the feasibility of implementing an anaerobic digestion (AD) system supplying biogas to a trigeneration system with energy storage for the provision of heating, cooling and power has been investigated in the context of a medium-scale arable farm. Two configurations – one supplied with wheat straw only, and the other supplied with wheat straw, barley straw and manure – were identified to meet the energy demands of the farm. Technical feasibility was investigated via simulations run in ECLIPSE, with the two configurations returning overall system efficiencies of 66.8% and 67.1%, respectively. Economic analyses indicated simple payback periods of 9.4 and 11 years, which fall within the expected 20-year lifetime of the project. Furthermore, the potential reduction in CO2 emissions for each scenario was determined to be 42,764 kg and 43,956 kg per year.
