比较了白色木屑颗粒（WWP）燃烧与三种类型煤（即美国，在这项研究中，俄罗斯和哥伦比亚的煤进行了调查。燃烧后捕获和存储（CCS），即与胺FG+，和氧燃料与碳捕获和存储（氧燃料）应用于650 MW的煤粉燃烧（PC）工厂。可再生能源义务证书（ROC）和碳价格（CP）政策在加速CCS部署的温室气体减排框架的影响，也进行了评估。综合环境控制模型考虑了影响电厂CCS成本和排放的运行因素（IECM 8.0.2）用于系统地评估电厂性能，本研究表明，利用白色木屑颗粒（WWP）每年可以避免650兆瓦发电厂排放约300万吨二氧化碳。然而，此缓解过程对工厂效率及电力成本产生影响。此外，使用白色木屑颗粒的BECCS显示出比燃烧后CCS技术更好的效率和更低的电力成本。然而，为了促进生物质能源CCS（BECCS）的部署与WWP，增加ROC的生物质发电厂，或，煤炭发电厂的碳价格的增加是推荐的。研究发现，COE对ROC的敏感性高于对碳价格变化的敏感性。这一结果可以解释为，从客户的角度来看，ROC比碳价格对COE有更积极的影响，而不会增加发电公司的负担。(C)2015爱思唯尔有限公司版权所有。
The technical performance and cost effectiveness of white wood pellets (WWP) combustion in comparison to three types of coal namely U.S., Russian and Colombian coals are investigated in this study. Post-combustion capture and storage (CCS) namely with amine FG+, and oxy-fuel with carbon capture and storage (oxy-fuel) are applied to a 650 MW pulverized combustion (PC) plant. The impacts of the Renewable Obligation Certificate (ROC) and carbon price (CP) policy in accelerating the CCS deployment in the framework of GHG emissions mitigation, are also evaluated. The operational factors affecting CCS costs and emissions in the power generation plants are taken into consideration, hence, the Integrated Environmental Control Model (IECM 8.0.2) is employed for a systematic estimation of plant performance, costs and emissions of different scenarios of fuel and CCS technologies.This study showed that the utilization of white wood pellets (WWP) in electricity generation can annually avoid about 3 M tonnes CO2 emissions from a 650 MW power plant. However, this mitigation process had impact on the plant efficiency and the cost of electricity. Further, the BECCS using white wood pellets has showed a better efficiency and lower cost of electricity with the oxy-fuel technology than the post-combustion CCS technology. However, in order to boost biomass energy CCS (BECCS) deployment with the WWP, an increase of the ROC for biomass power plants, or, an increase of the carbon price for the coal power plants is recommended. It was found that, the sensitivity of COE towards the ROC was higher than towards the carbon price variation. This result can be interpreted as the ROC has more positive impact than the carbon price, on the COE from the point of customers view without adding more burdens on the power generation companies.
