将生物质燃料发电厂与碳捕获和储存相结合，可以将二氧化碳从大气中去除，将生物质视为碳中性燃料。在本研究中，生物质为基础的CO2负系统已被提出，它结合了生物质蒸汽气化设施与固体氧化物燃料电池，燃烧后的碳捕获设施与熔融碳酸盐燃料电池（MCFC），和废热回收使用有机朗肯循环。对两种情景进行了技术经济分析，即a）使用基于MCFC的CO2捕集和B）不使用CO2捕集。MCFC和碳捕集系统的集成能够捕集99.2%的CO2。结果发现，随着CO2捕获设施的引入，系统的能源效率降低了9.43%。此外，有CO2捕集和无CO2捕集的配置的火用效率分别为62%和70.22%。经济分析表明，平准化电力成本（LCOE）的配置与CO2捕集和没有CO2捕集估计为0.062 $/kWh和0.052 $/kWh，分别。最后，生命周期的CO2排放量的两种情况下已经执行，分析表明，拟议的CO2负系统是能够捕获1100吨CO2每年。
Combining biomass-fuelled power plant with carbon capture and storage allows CO2to be removed from the atmosphere, considering biomass a carbon–neutral fuel. In the present study, a biomass-based CO2negative system has been proposed, which combines a biomass steam gasification facility with a solid oxide fuel cell, a post-combustion carbon capture facility with a molten carbonate fuel cell (MCFC), and waste heat recovery using the organic Rankine cycle. A techno-economic analysis of two scenarios, namely a) with MCFC-based CO2capture and b) without CO2capture, was conducted. Integration of MCFC and carbon capture system was able to capture 99.2% of CO2. It was found that the energy efficiency of the system was decreased by 9.43%, with the incorporation of CO2capture facilities. Furthermore, exergy efficiencies for the configuration with CO2capture and without CO2capture are calculated as 62% and 70.22%, respectively. The economic analysis reveals that the levelized cost of electricity (LCOE) for the configuration with CO2capture and without CO2capture is estimated to be 0.062 $/kWh and 0.052 $/kWh, respectively. Finally, life cycle CO2emissions for both the scenarios have been performed, and the analysis reveals that the proposed CO2negative system is able to capture 1100 tonnes of CO2per year.
