BIOMASS AND BIO-ENERGY UTILISATION IN A FARM-BASED COMBINED HEAT AND POWER FACILITY

摘要

Five different renewable energy technologies located at an agricultural and environmental researchrncentre (AFBI Hillsborough) were monitored to assess the cost, performance and efficiency of biomass produced fromrnfarm wastes and cropsutilised for energy generation in industrial grade equipment in real-time operation. Researchrnwas conducted over a six year period, with power units running simultaneously or intermittently according to demandrnfrom the system. The purpose of the work was to investigate fossil fuel (oil) displacement, carbon dioxide (CO_2e)rnemissions reduction, financial and environmental sustainability of these technologies in a farm based scenario.rnBetween 2009 and 2014, total heat output from the centre was 7,750MWh with contributions of 47.2 %, 17.1 %,rn9.8% and 13.5 % from the biomass, biogas, multi-fuel boiler and biogas CHP unit respectively. Solar thermalrnproduced 0.49 % and the back-up oil boiler 11.9 %. Total electrical output was 545.3MWh(e) with 94.2 %rngeneratedfrom biogas CHP and 5.8 % from the solar PV system. Fossil fuel and average CO_2e reductions rangedrn20.1 % to 54.1% and 23.3 to 55.7 % respectively. These reductions combined with financial savings to present arnviable and sustainable renewable energy system.
