Bioenergy with carbon capture and storage (BECCS) has the potential to remove carbon dioxide from the atmosphere and ultimately play an important role in climate change mitigation. The aim of this research is to compare the techno-economic performance of different types of biomass in different CO₂ abatement technologies via simulations. This is information that is currently not available in the BECCS literature and the present study constitutes the first attempt to bridge this knowledge gap.

Simulations revealed that potentially annual CO₂ negative emissions of 1.0 Mt up to 1.52 Mt can be achieved for a 250 MW power plant when biomass is coupled with the appropriate CCS technology. Economic analysis estimated that CO₂ avoidance costs in the range of £46- £88 per tonne of CO₂ are required to match the cost of bioenergy generation without CCS. A sensitivity analysis to investigate the effect of carbon pricing as an economic tool suggested that a carbon price range of £83 - £146 per tonne of CO₂ is necessary to compete with natural gas. A parametric analysis on the LCOE identified the high fuel cost as the major cost driver; other significant factors are the plant capacity factor and the capital charges.

带有碳捕获和存储（BECCS）的生物能源具有从大气中清除二氧化碳的潜力，并最终在缓解气候变化中发挥重要作用。这项研究的目的是通过模拟比较不同类型的生物质在不同的CO ₂减排技术中的技术经济性能。这是BECCS文献中目前尚无的信息，本研究是弥合这一知识鸿沟的首次尝试。

模拟显示，如果将生物质与适当的CCS技术结合使用，对于250兆瓦的发电厂，可能实现1.0 Mt至1.52 Mt的潜在年度CO ₂负排放量。经济分析估计，与不使用CCS的生物能源发电成本相匹配，避免每吨CO _2的CO ₂避免成本在46-88英镑之间。对碳定价作为一种经济工具的影响进行的敏感性分析表明，与天然气竞争，每吨CO ₂的碳价格范围必须在83英镑至146英镑之间。对LCOE进行的参数分析确定，高燃油成本是主要的成本驱动因素。其他重要因素是工厂产能因素和资本费用。
