考虑政策补贴机制的燃煤机组绿氨掺烧全流程技术经济性分析
Technical and economic analysis of the entire process of green ammonia co-firing in coal-fired units considering the policy subsidy mechanism
摘要
Abstract
Green ammonia co-firing is one of the important technical routes for the low-carbon transformation of coal-fired power units.Currently,the main problem restricting the promotion of green ammonia co-firing projects is the poor economic efficiency of the entire process from green ammonia production,storage and transportation to co-firing.Taking a single 600 MW coal-fired unit co-firing 10%green ammonia as an example,the technical and economic efficiency of the entire process of off-grid/on-grid photovoltaic power generation for green ammonia synthesis and co-firing projects is compared and analyzed.Moreover,the effects of subsidy mechanisms(zero-carbon electricity subsidy,green ammonia production subsidy,carbon emission reduction subsidy and low-interest loan)on project benefits are deeply discussed.The results show that,the price of coal and carbon tax is the main factor affecting the economic efficiency of the project.As the price increases,the economic benefits of green ammonia co-firing in coal-fired units are significantly improved.All subsidy mechanisms can improve the economic efficiency of the project,but the effects vary depending on the scenario.Low-interest loans have the best effect on improving the economic feasibility of the project,while zero-carbon electricity subsidies have the highest sensitivity to the change in the project's net present value(NPV).关键词
