The Study Of Investment Planning And Low Carbon Profit Analysis Of Carbon Capture System In Plants

Faced with the tendency of global warming, the CO₂emission reduction has been thecommon responsibility all over the world. Among the emission reduction technologiesemerging as the times require, CO₂capture and storage （CCS） technology has become aresearch hotspot in recent years at home and abroad. Some demonstration projects havebeen built. The opportunity for large-scale development is close at hand. But opportunitiesand challenges exist at the same time. The cost of investment is so high that makes itbecome the most significant obstacle for CCS development. Therefore, it is needed toprovide reasonable planning for carbon capture system investment, analyze theimplementation of relevant policy and propose rational suggestion, in order to reduce theburden of the generation corporation and promote the development of emission reductioncareer. Moreover, the coordination investment of other emission reduction methods andcarbon capture system is an important approach to obtain more profit.The investment problem of carbon capture system has been studied and analyzed inthis paper from two aspects respectively which are short term planning and long termplanning for carbon capture system in order to provide investment decision and referencesuggestion for the generation corporation. The main contents of this paper are as follows:At first, the operating principle of three kinds of CO₂capture technologies and theprogress of CCS project at home and abroad are introduced briefly. Based on theintroduction before, the development prospect and policy demand of our country’s CCSproject are predicted. Moreover, the real option theory and pricing method are summarizedand the application of them is analyzed.Moreover, the short-term planning problem of carbon capture system investment isstudied under the context of carbon emission trade system. An emission reductionplanning model is built aimed at the maximizing the comprehensive profit for generationcorporation during the planning time and based on the B-S option pricing theory to reckonin the option value considering the investment flexibility for carbon price fluctuation. Themodel is solved by discrete bacterial colony chemotaxis algorithm （DBCC）. The simulation results provide the short-term deployment schemes for the carbon capturesystem. What’s more, the schemes have been analyzed in detail in order to offerinstructions for the generation corporation.At last, the long-term planning problem of carbon capture system and wind powercoordination investment is studied. A complete low carbon profit concept is proposed,namely the CO₂emission reduction for per unit investment of a certain emission reductionproject in its all life cycle. And a model is built to coordinate the investment of carboncapture system and wind power aimed at maximizing the low-carbon profit. Thesimulation result provides a long-term investment scheme for carbon capture system andwind power. And the scheme is evaluated from the aspects of technical feasibility,economic reasonability and social friendliness to provide instruction for the investmentchoice of the generation corporation in future.
