尽管存在环境威胁，但随着间歇性可再生能源在能源结构中所占份额的增加，煤炭预计仍将是一种显著的能源；因此，在推动清洁替代品的同时，管理二氧化碳（CO2）等污染物至关重要。碳捕获、利用和封存（CCUS）是一套从排放中去除二氧化碳并将其长期安全储存的方法。就目前而言，CCUS的价格高得令人望而却步；然而，边做边学是一种公认的现象，它有助于新技术在持续使用的过程中变得更便宜。因此，为了准确的长期规划，本研究考虑了内生技术学习（ETL），研究了早期采用者对CCUS市场扩散的影响。建立了一个混合整数非线性规划模型（MINLP），在考虑技术经济约束和法规约束的情况下，确定燃烧后碳捕集装置的最优容量和部署时间以及CO2供应链中最优源链匹配。利用Stackelberg对策方法将MINLP模型转化为一系列混合整数线性规划模型，并用对角化方法求解。得到了参与者独立和协调行动时模型的均衡解。所提出的模型适用于具有多个二氧化碳源和汇的土耳其能源市场，该市场假定已经实施了限额与交易计划。虽然该研究证明了土耳其CCUS和ETL之间的相互作用，但所提出的模型是通用的，如果输入可用，它可以应用于其他国家。(C) 2020 Elsevier Ltd.版权所有。
Despite environmental threats, coal is expected to remain a remarkable energy source as the share of intermittent renewable sources in the energy mix grows; hence, managing pollutants such as carbon dioxide (CO2) is critical while pushing for clean alternatives. Carbon capture, utilization, and storage (CCUS) is a set of methods that removes CO2 from emissions and stores it safely for the long-term. As it stands now, CCUS is prohibitively expensive; however, learning-by-doing is a recognized phenomenon that assists novel technologies to become more affordable as employed continuously. Thus, for accurate long-term planning, this study investigates the impact of early adopters on CCUS market diffusion considering endogenous technology learning (ETL). A mixed-integer nonlinear programming model (MINLP) is developed which determines the optimal capacity and deployment time of post-combustion carbon capture units and the optimal sourceesink matching in the CO2 supply chain, taking into account techno-economic constraints and regulations. The MINLP model is transformed into a series of mixed-integer linear programming models using a Stackelberg game approach and solved with a diagonalization method. Equilibrium solutions of the proposed model were obtained for independent and coordinated actions of players. The proposed model is applied to the Turkish energy market with multiple CO2 sources and sinks, where a cap-and-trade program is presumed to be in place. While the study demonstrates the interplay between CCUS and ETL in Turkey, the proposed model is universal, and it can be applied to other countries if the inputs are available.
