为避免全球气候变化对人类社会造成不可逆转的影响，近年来许多国家都提出了加快能源体系低碳转型的宏伟目标。在低碳措施中，用生物质共烧改造现有的燃煤电厂被认为是一种有希望的经济有效的选择，可以减少温室气体和空气污染物的排放。然而，对于不同地区的不同类型的发电厂来说，这种煤制生物质改造的生命周期经济成本或环境效益并不相同。为了在能源系统中促进更有效的生物质利用战略，有必要对改造后的工厂中生物质和煤的共烧进行大规模和高分辨率的成本效益评估。本研究以中国为例，运用自底向上方法和地理信息系统，结合现有最新数据集，构建了煤向生物质转型的单位层面成本效益分析框架。结果表明，在混合比例为25%的情况下，煤转生物质改造每吨碳减排成本为18.3-73.0美元，每公斤二氧化硫减排成本为21.6-806.5美元。装机容量、运行年限和运输距离是影响成本效益异质性的重要因素。机组改造在碳减排方面的优先度主要取决于成本偏好，而在so2减排方面的优先度主要取决于效益偏好。本研究提出的分析框架可用于其他国家制定有效的生物质发展战略。
To avoid the irreversible impact of global climate change on human society, many countries have recently put forward ambitious goals to accelerate the low-carbon transition of energy systems. Among low-carbon measures, retrofitting existing coal power plants with biomass co-firing is regarded as a promising cost-efficient option to mitigate greenhouse gas and air pollutant emissions. However, the life-cycle economic cost or environmental benefit of this coal-to-biomass retrofit is not identical for various types of power plants in different regions. To facilitate a more efficient biomass utilization strategy in an energy system, it is necessary to carry out a large-scale and high-resolution cost-benefit assessment for the co-firing of biomass and coal in retrofitted plants. Taking China as an example, this study utilized a bottom-up approach and geographic information system, combined with the latest available datasets, to develop a unit-level cost-benefit analysis framework for the coal-to-biomass transition. The results indicate that the coal-to-biomass retrofit costs US$18.3–73.0 for each ton of carbon reduction, and US$21.6–806.5 for each kg of SO2reduction, at a 25% blending ratio. Installed capacity, operating year, and transportation distance are important influencing factors of cost-benefit heterogeneity. The priority of power unit retrofitting in terms of carbon reductions mainly depends on the cost preference, while that for SO2reduction is mainly determined by benefit preference. The analytical framework proposed in this study can be used in other countries to formulate an efficient biomass development strategy.
