This paper presents the findings of the techno-economic assessment undertaken by Wood for the UK Government Department for Business, Energy and Industrial Strategy on the large-scale deployment of Molten Carbonate Fuel Cells (MCFCs) for post-combustion CO2 capture integrated with a new build combined cycle gas turbine power plant for the generation of low carbon electricity. Based on a new build power plant to be installed in the North East of England, with a power train comprising two trains of H-class gas turbines each with a dedicated steam turbine, the configuration presented utilises MCFCs between the gas turbine exhausts and their heat recovery steam generators and cryogenic separation for unconverted fuel recycle and CO2 purification. It was found that the proposed configuration could achieve 92% CO2 capture from the overall power plant with MCFCs while achieving 42% of additional new power production with only 2.6 %-points of thermal efficiency penalty compared to a conventional proprietary amine benchmark. While the total project capital cost increased by 65%, the high overall thermal efficiency and additional power generated resulted in a Levelised Cost of Electricity almost identical to the benchmark at £70/MWh (US$97/MWh). A number of areas are identified for potential further improvement in this scheme. It is concluded that use of MCFC technology, which also has the capability to be tailored for hydrogen production and combined heat and power services, shows significant potential to be competitive with, or exceed, the performance of current state of the art technologies for post-combustion CO2 capture.

用于从新建 CCG​​T 中捕获 90% 燃烧后二氧化碳的熔融碳酸盐燃料电池

本文介绍了伍德为英国政府商业、能源和工业战略部就大规模部署熔融碳酸盐燃料电池 (MCFC) 用于燃烧后二氧化碳捕集与新的一是建设联合循环燃气轮机发电厂，用于低碳发电。基于将在英格兰东北部安装的新建发电厂，其动力传动系由两列 H 级燃气轮机组成，每列都有一个专用的蒸汽轮机，所呈现的配置在燃气轮机排气和它们的热量之间使用 MCFC用于未转化燃料再循环和二氧化碳净化的回收蒸汽发生器和低温分离。结果发现，与传统的专有胺基准相比，所提出的配置可以实现 MCFC 从整个发电厂捕获 92% 的二氧化碳，同时实现 42% 的额外新发电量，热效率损失仅为 2.6%。虽然项目总资本成本增加了 65%，但整体热效率高和产生的额外电力导致平准化电力成本几乎与基准 70 英镑/兆瓦时（97 美元/兆瓦时）相同。确定了该计划有可能进一步改进的许多领域。结论是，使用 MCFC 技术，该技术还具有为制氢和热电联产服务量身定制的能力，显示出与，或超越，竞争的巨大潜力，
