摘要
在双碳背景下,提出一种基于生命周期的洁净煤发电技术环境影响评估方法,旨在提升能源的利用效率、降低温室气体的排放。以超超临界和超临界发电技术为研究对象,构建了生命周期评估模型,并对其整个生命周期内对环境的影响进行了量化分析。结果表明,燃煤阶段是所有环境影响类型中的主要贡献者。超超临界发电技术在非生物资源消耗、固体废物潜值、算法潜值和全球变暖潜值环境影响中的燃煤阶段占比分别为88.14%、21.28%、99.29%和90.28%,超临界发电技术在相应环境影响中的燃煤阶段占比分别为82.81%、23.66%、99.78%和85.24%。敏感性分析进一步证实,全球变暖潜值为最敏感的环境影响因素。研究为双碳背景下减排策略的制定及洁净煤发电技术的优化提供了数据支撑和思路方向,推动了能源行业的可持续发展。
In the context of dual-carbon,an environmental impact assessment method based on life cycle for clean coal power generation technology was proposed to improve energy utilization efficiency and reduce greenhouse gas emissions.Taking the ultra supercritical and supercritical power generation technologies as the research object,a life cycle assessment model was constructed,and their impact on the environment throughout their entire life cycle was quantitatively analyzed.The research results indicate that the coal-fired phase is the main contributor to all types of environmental impacts.The coal-fired stage of ultra supercritical power generation technology accounts for 88.14%,21.28%,99.29%,and 90.28%of non biological resource consumption,solid waste potential,algorithm potential,and global warming potential environmental impacts,respectively.The coal-fired stage of ultra supercritical power generation technology accounts for 82.81%,23.66%,99.78%,and 85.24%of the corresponding environmental impacts.Sensitivity analysis further confirms that global warming potential is the most sensitive environmental impact factor.This study provides data support and direction for the formulation of emission reduction strategies and the optimization of clean coal power generation technology under the dual carbon context,promoting the sustainable development of the energy industry.
