Bioenergy prospects in Taiwan using set-aside land - an economic evaluation

Purpose - This study aims to explore Taiwan's potential for bioenergy production using feedstocks grown on set-aside land and discusses the consequent effects on Taiwan's energy security plus benefits and greenhouse gas (GHG) emission. Design/methodology/approach - The Modified Taiwan Agricultural Sector Model (Modified TASM), based on price endogenous mathematical programming, was used to simulate different agricultural policies related to bioenergy production. To do this simulation, the TASM model was extended to include additional bioenergy production possibilities and GHG accounting. Findings - Taiwan's bioenergy production portfolio depends on prices of ethanol, electricity and GHG. When GHG prices go up, ethanol production decreases and electricity production increases because of the relatively stronger GHG offset power of biopower. Originality/value - Taiwan is interested in producing bioenergy but only limited information is available. This study provides the information on potential bioethanol and bioelectricity production from various energy crops, GHG emission offset from bioenergy, and regional energy security.
