碳捕集系统与风电协调投资的低碳效益分析

Low-Carbon Benefit Based Analysis on Coordinating Investment for Carbon Capture System and Wind Power System

随着CO2减排要求日趋明确,各种减排技术日渐成熟和完善。通过不同减排技术的选择与配合,使得发电企业在保证效益的同时兼顾减排的要求是值得研究的重要课题。为此,依据价值工程理论提出低碳效益的概念,即全寿命周期内某减排项目单位投资的碳减排量,使不同的技术或评价方式具有可比性,并建立技术可行性、经济合理性和社会友好性3个指标对其进行评价;然后以低碳效益最大化为目标建立碳捕集系统与风电的协调投资模型,给出符合经济发展趋势和减排要求的投资规划方案,最后从3个指标的角度进行评价,为今后减排项目的发展提供指导意见。

Along with the demand on CO2 emission reduction becoming more and more explicit, various emission reduction technologies are matured and perfected more and more. It is an important subject to be worth researching to make power generation enterprises ensuring their benefits with the demand on emission reduction being considered through the selection and coordination of different emission reduction technologies. For this purpose, according to the theory of value engineering, a concept of low-carbon benefit, i.e., the quantity of carbon emission reduction under specific investment for a certain emission reduction project during its life cycle, is proposed to make different technologies or assessment methods comparable, and three indices, namely technical feasibility, economic rationality and social friendliness, are established to perform the assessment; then taking the maximization of low-carbon benefit as the objective, a model to coordinate the investment for carboncapture system and wind power system is built; and then an investment planning scheme that confirms to both economic development trend and demand on carbon emission reduction is given; finally, from the perspective of the three indices the assessment is performed to offer guiding opinion for the development of emission reduction projects in future.
