按中国农村户用沼气池的不同适用对象分类对其运行成本分别进行了研究,并分析了其不同的温室气体减排效果以及在清洁发展机制(CDM)下出售这些减排权(CERs)可以带来的额外经济效益,对改善沼气工程直接经济效益的措施进行了讨论。结果表明:沼气工程直接经济效益不高,在清洁发展机制(CDM)下通过出售减排权(CERs),经济性可得到改善。沼气项目对于燃煤的农户将具有市场竞争力和投资吸引力。
According to the classification of different suitable objects for household biogas digesters in rural China, their operating costs are separately studied and their different greenhouse gas emission reduction effects are analyzed and the rights to sell these emission reduction rights (CERs) under the CDM Brought about additional economic benefits, to improve the direct economic benefits of biogas project measures were discussed. The results show that the direct economic benefits of biogas projects are not high and the economy can be improved through the sale of emission reduction rights (CERs) under the Clean Development Mechanism (CDM). Biogas projects will be market competitive and attractive for farmers that produce coal.
