考虑到可再生能源是未来的主要能源，本研究对生物质发电的可持续和安全能源供应进行了研究。马来西亚的生物质燃料包括空果串、中果皮纤维、棕榈仁壳、油棕榈叶、棕榈油种植园的油棕榈树干和来自森林的木质生物质。对以棕榈油为基础的生物质燃料的含水率和热值进行了分析，并与其在10兆瓦生物质发电厂中节省的成本进行了比较。还给出了不同融资选择和不同系统效率下的净现值、内部收益率和回收期。结果表明，无贷款定价为20马币/吨的空果串，净现值分别为4531万马币、5432万马币和5774万马币，系统效率分别为20%、30%和40%；内部收益率分别为21.88%、22%和21.11%；投资回收期分别为4.16、4.20和4.22年。与现有的能源组合相比，这座10兆瓦的发电厂在环境中排放的二氧化碳减少了50,130吨，二氧化硫减少了750吨，氮氧化物减少了218.65吨，一氧化碳排放量减少了22.83吨。
Considering that renewable energy is the primary energy source in the future, this study investigates biomass power for sustainable and secure energy supply. Biomass fuels in Malaysia include empty fruit bunch, mesocarp fiber, palm kernel shell, oil palm frond, oil palm trunk from palm oil plantation, and woody biomass from forests. The moisture content and heating value of palm oil-based biomass fuels are analyzed relative to their cost savings in a 10 MW biomass power plant. The net present value, internal rate of return, and payback period for various finance options and at various system efficiencies are also presented. Results indicate that for an empty fruit bunch priced at MYR 20/t without loan, the net present values are MYR 45.31 million, MYR 54.32 million, and MYR 57.74 million, with 20%, 30%, and 40% system efficiencies, respectively; the internal rates of returns are 21.88%, 22%, and 21.11%, respectively; and the payback periods are 4.16, 4.20, and 4.22 y, respectively. The 10 MW plant releases 50,130 t less CO2, 750 t less SO2, 218.65 t less NOx, and 22.83 t less CO emissions in the environment compared with the existing energy mix.
