| Summary: | 碩士 === 東海大學 === 環境科學與工程學系 === 99 === The world is now faced with energy crisis and global warming, giving rise to the global renewable energy development. Utilizing biomass residues to replace fossil fuel is a good way to abate GHG emissions and solve waste problems. Currently, the Clean Development Mechanism (CDM) has a range of biomass residue-to-energy related methodologies, though it lacks number of implemented projects. Therefore, this thesis focuses on the feasibility study of biomass residue utilization for energy in Taiwan.
The study focuses on project based rice husk utilization in Taiwan, with 3 source-based scenario analyses: local (Taiwan), import from China, and from Vietnam. The CDM methodology is used as calculation tool for the emission reductions, taking into consideration the emission reduction credits to lever the development risks. The study also includes Internal Rate of Return (IRR) and sensitivity analysis to estimate the project investment feasibility.
The study shows that all 3 scenarios generate emission reduction and financial return. The locally sourced rice husk generates the highest investment return, due to the minimized transportation costs and maximized number of emission reduction credits. The project generates 15,940.29 tCO2e/year, with total annual revenue of USD 1,023,717.43 including carbon revenues, and USD 896,195.11 without carbon revenues. In light of renewable development in Taiwan, the shortage of biomass residue sources would hinder this type of project being implemented in the region. Hence, rice husk import from China and Vietnam was also considered.
