Biofuel trigeneration with energy storage for heating, cooling and power on farms

Tang, Zhaozhao and Ly, Sammi and Wang, Yaodong and Huang, Ye and Luo, Jingting and Fu, Chen (2021) 'Biofuel trigeneration with energy storage for heating, cooling and power on farms.', Energy Reports, 7 . pp. 5394-5405.

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.
