本計畫係為環保署推動區域性生質能中心之延續性工作，主要是「興設離島地區生質能源中心」，本計畫尚包括焚化廠區域冷熱系統、評估以民間促參設置生質能設施、配合環保署出國考察及辦理相關研討會等工作項目。「興設離島地區生質能源中心」，經綜合考量環保署任務執掌、離島技術支援能力、能源回收經濟效益等因素，將修訂原報院計畫，並擬採「模組化垃圾分選(新建)+垃圾處理設施(改善)+垃圾轉運(既存)」。至於離島沼氣提純CNG車用燃料，因涉及界面問題與阻礙，建議由本島試辦以累積經驗。促參推動生質能設施，必須以廚餘作為保證交付量。基於國內推動垃圾強制分類及隨袋徵收政策，北部地區廚餘潛在量大，具有獨自興建厭氧消化能源設施，中南部除少數廚餘外，尚有為數可觀的禽畜糞廢，可一併納入處理以增加經濟規模。經濟效益分析結果，在進場費及售電收入不足夠情況下，難以吸引民間廠商投資，必須仰賴政府補貼。建置焚化廠區域冷熱供應系統，篩選桃南廠、利澤廠及仁武廠與工業區廠商進行蒸汽媒合鏈結。經濟效益分析結果(以單位能源成本計算)，桃南廠、利澤廠及仁武廠每年的外售蒸汽淨收入，分別為1,957萬元、251萬元及6,448萬元；總熱效率部分，桃南廠、利澤廠及仁武廠能提高2.7%、2.8%及6%；溫室氣體排放每年減少約9萬公噸。推動方式建議由經濟部統籌綜理(環保署提供垃圾調度等行政支援)，區域蒸汽管網的初設成本得研提經建計畫或與能源服務公司(ESCO)簽訂投資及操作營運長期契約

The project is an extending work for Environmental Protection Administration (EPA) to promote the installation of regional bioenergy centers, especially for three islets out of main territory of Taiwan island. The major scope of work also includes developing district heating and cooling system around refuse incineration plants and other services accompanied with EPA policies on public and private partnership (PPP), assistance on field trip plans abroad and holding a local technical forum. The master plan on promotion of installing regional bioenergy centers at three islets is revised according to comprehensive policy evaluation by EPA when considering local technical supports and overall cost benefit effects. The plan was then amended to enhance the existing refuse treatment scheme which is going to install new modular waste sorting equipment, retrofit the existing waste treatment facilities, and keep subsidizing shipping and transportation of waste to refuse incineration plants in Taiwan island. Moreover, a study on bio-CNG application to vehicles from potential bioenergy centers recommends that pilot project be execute in Taiwan island first instead of at the three islets, due to economic scale of productivity, logistic barriers and other inevitable interfaces. In terms of PPP model to promote bioenergy facilities, a guaranteed amount of kitchen waste is one of the crucial factors to success. Based on different refuse source separation and pay-as-you-throw policies in Taiwan, cities in northern area bear potential and priority to construct regional anaerobic digestion (AD) bioenergy centers since the kitchen waste amount is relatively sufficient. On the other hand, cities and counties in central and southern area, various livestock manures are the major feedstocks to AD bioenergy centers, which could be in combination with few local kitchen waste to support AD facilities in a reasonable economic scale. The financial analysis also shows that it is difficult to be self-liquidated under an insufficient income of tipping fee and energy sale price. In case to attract private investment, government subsidy shall be necessary. For developing district heating and cooling system around refuse incineration plants, Taoyuan Plant, Letzer Plant and Renwu Plant are recommended since they are adjacent to local industrial manufacturers which have process steam requirements. Economic analysis indicated that the net annual income from steam sale based on recent unit price for Taoyuan, Letzer and Renwu Plant was 19.57, 2.51 and 64.48 million NT dollars, respectively. Regarding the total thermal efficiency, Taoyuan, Letzer and Renwu Plant will be increased by 2.7%、2.8% and 6%. The greenhouse gas (GHG) emission will be also reduced about 90,000 metric tons per year in total CO2 equivalent. The way to reach the above mentioned synergy was suggested to be led by Ministry of Economic Affairs with the administrative support from EPA in waste management and dispatch. The initial cost required for district heating and cooling system should be directly subsidized by government sectors through applying Economical Developing Project, or make a deal with Energy Services Companies (ESCO) for a long term contract of investment and operation.
