基于生物质的发电与二氧化碳捕获和储存相结合(BiopPower CCS)目前是从大气中去除大量二氧化碳的为数不多的实用和经济的方法之一，也是同时涉及发电的唯一方法。我们介绍了二氧化碳捕集生物质发电技术经济研究(TESBiC)项目的结果，该项目需要基于桌面的审查和分析、过程工程、优化以及从一些领先的试点示范工厂收集原始数据。从能够在2050年前部署BiopPower CCS的角度出发，确定和评估了28种涉及生物质燃烧或气化(专用或与煤共燃)以及燃烧前、燃烧后或燃烧后二氧化碳捕获的BiopPower CCS技术组合。除了资本和运营成本外，假设从今天到2050年的技术改进，还将随着时间的推移模拟电效率(LHV%)、统一电力成本(LCOE)、捕获和避免二氧化碳的成本等技术经济特征。在相同规模的分析中，许多BiopPower CCS技术给出了相对相似的技术经济结果，工厂规模(MWe)被认为是资本支出(磅/Mwe)的主要驱动因素，混烧%(即加权原料成本)是LCOE的关键驱动因素。TESBiC项目期间收集的数据还突出表明，对二氧化碳排放量为负的发电缺乏财政奖励。(C)2016爱思唯尔有限公司。保留所有权利。
Biomass-based power generation combined with CO2 capture and storage (Biopower CCS) currently represents one of the few practical and economic means of removing large quantities of CO2 from the atmosphere, and the only approach that involves the generation of electricity at the same time. We present the results of the Techno-Economic Study of Biomass to Power with CO2 capture (TESBiC) project, that entailed desk-based review and analysis, process engineering, optimisation as well as primary data collection from some of the leading pilot demonstration plants. From the perspective of being able to deploy Biopower CCS by 2050, twenty-eight Biopower CCS technology combinations involving combustion or gasification of biomass (either dedicated or co-fired with coal) together with pre-, oxy- or post-combustion CO2 capture were identified and assessed. In addition to the capital and operating costs, techno-economic characteristics such as electrical efficiencies (LHV% basis), Levelised Cost of Electricity (LCOE), costs of CO2 captured and CO2 avoided were modelled over time assuming technology improvements from today to 2050. Many of the Biopower CCS technologies gave relatively similar techno-economic results when analysed at the same scale, with the plant scale (MWe) observed to be the principal driver of CAPEX ( pound/MWe) and the cofiring % (i.e. the weighted feedstock cost) a key driver of LCOE. The data collected during the TESBiC project also highlighted the lack of financial incentives for generation of electricity with negative CO2 emissions. (C) 2016 Elsevier Ltd. All rights reserved.
