CCUS煤层气开采项目经济可行性分析

Economic feasibility analysis of CCUS project for coal-bed methane exploitation

摘要: 相对于一般煤层气开采项目而言,CCUS煤层气开采项目经济环境效益显著,但投资风险大,本文利用现金流量法对案例项目进行了经济评价和影响因素敏感性分析。结果表明CCUS煤层气开发项目尚不能达到煤层气行业的基准盈利要求,经济上难以实行。项目内部收益率对CO₂捕集成本、产气量、煤层气销售价格等因素较为敏感。提高该类项目经济可行性,需要一项甚至多项敏感性因素的组合调整,推动CCUS煤层气项目实施需要相关技术研发和鼓励政策的制定。

Abstract: CCUS project for Coal-bed methane exploitationhas significant economic and environmental benefits,but it also has high risk.The economic feasibility of CCUS project has been analyzed by using cash flow method.The results show that CCUS projects not feasible because it cannot achieve the hurdle rate.IRR (internal rate of return) of CCUS project is sensitive to CO₂ trapping cost,gas production and coal-bed methane sales price and other factors.In order to improve the economic feasibility of CCUS project,a number of sensitive factors need adjustment.Besides,it is necessary to develop related technology and formulate supportive policy forimplementation of CCUS project.
