背景生物甲烷是一种从沼气升级而来的清洁燃料。它具有与天然气汽车（NGV）相似的特性，可在运输和工业部门用作化石燃料的替代品。目前，生物甲烷还没有被广泛用作替代能源，因为它依赖于当地的沼气生产。然而，替代品很少，商业系统的规模也很小。因此，本文的总体目标是研究当地沼气聚集生产不同规模的生物甲烷的财务可行性。预计研究结果将有助于投资者和政府在促进使用可再生和可持续能源方面的决策。方法以净现值、内部收益率、投资回收期和单位成本为金融工具，采用一级和二级数据进行描述性和定量分析。所应用的定位和距离方法是基于通过水洗涤的沼气升级的谷歌地图和Power BI软件程序。结果泰国存在10个潜在的生物甲烷生产区，在天然气管道不超过50 km的条件下，总沼气生产能力为6,000 m3/d或以上。6吨/日以下的压缩生物甲烷气厂，政府出资比例为总投资的30%，投资回收期为5-6年。即使没有政府资助，日产量超过6吨的工厂也能提供良好的投资回报。结论虽然这项研究只集中在泰国的地区，这是研究人员的立场，残余沼气厂的整合提供了更大的好处比耀斑，特别是在偏远地区。本研究提出的模型可以作为马来西亚、菲律宾、拉丁美洲等发展中国家的原型，也可以用于根据《巴黎协定》致力于减少温室气体排放的发达国家。
Background Biomethane is a clean fuel upgraded from biogas. It has similar properties to natural gas vehicle (NGV) and can be used as a substitute for fossil fuels in the transportation and industrial sectors. Currently, biomethane is not in widespread use as alternative energy because it depends on local biogas production. However, there are few replacement alternatives and the commercial system is only on a small scale. Therefore, the overall aim of this paper is to study the financial feasibility of local biogas aggregation for producing biomethane on various scales. The results of the study are expected to aid the decision-making of investors and governments in promoting the use of renewable and sustainable sources of energy. Methods Primary and secondary data are used in this research for descriptive and quantitative analysis, while net present value, internal rate of return, payback period, and cost per unit represent the financial instruments. The location and distance methods applied are Google Maps and Power BI software programs, based on biogas upgrading by water scrubbing. Results The results indicate that 10 potential biomethane production areas exist in Thailand, with a total biogas production capacity of 6,000 m(3)/day or more under gas pipeline conditions not exceeding 50 km. Compressed biomethane gas plants with a capacity of less than 6 tons/day should be funded by the government at 30% of the total investment for a payback period of 5-6 years. Plants producing more than 6 tons/day provide a good return on investment even without government funding. Conclusions While this study focuses solely on areas of Thailand, it is the researcher's position that the integration of residual biogas plants provides greater benefit than flare, particularly in remote areas. The model proposed in this study can serve as a prototype for developing countries such as Malaysia, the Philippines, Latin America, etc. Furthermore, it can be used in developed countries committed to reducing greenhouse gas emissions in accordance with the Paris Agreement.
