This study explores the prospective techno-economic performance of facilities that produce low- and net-negative-carbon liquid transportation fuels and electricity with CO₂ capture for enhanced oil recovery. The lignite and biomass-to-jet fuel process is based on KBR’s TRIG gasifier, Rectisol (for sulfur removal and CO₂ capture), fixed-bed low temperature Fischer-Tropsch synthesis of liquid fuels, and Brayton/Rankine combined cycles to convert synthesis/refining off-gases and waste heat to electricity. This work leverages a recent, highly-detailed assessment of a prospective first-of-a-kind (FOAK) demonstration facility to develop highly detailed Aspen Plus process simulations for nine prospective N^th-of-a-kind (NOAK) plant equipment configurations. Component-level capital costs from the FOAK study are scaled and adjusted to reflective prospective learning-by-doing to estimate capital costs for the NOAK designs. NOAK plant economic performance is found to be largely insensitive to variations in plant configurations and electricity output fraction, but biomass input fraction significantly affects profitability. Facilities that consume only carbon–neutral biomass, with no lignite co-feed, have significantly net-negative carbon emissions and the most favorable prospective economics when carbon emissions are priced. For these facilities, the crude oil price required for plant economic viability falls rapidly from $100/bbl as carbon emission prices increase above $120/tonne CO_2eq. In general, plants that co-fire lignite with biomass are less profitable (than 100% biomass plants) due to their higher net greenhouse gas emissions.

这项研究探讨了生产低碳和净负碳液体运输燃料和电力并捕获CO ₂以提高石油采收率的设施的预期技术经济性能。褐煤和生物质到喷气燃料的工艺基于KBR的TRIG气化炉，Rectisol（用于脱硫和CO ₂捕集），固定床低温费托合成液体燃料以及Brayton / Rankine联合循环来转化合成/净化废气并将废热转化为电能。这项工作利用了对潜在的首创（FOAK）演示设施的最新，高度详细的评估，为9个预期的^第N^个开发高度详细的Aspen Plus工艺模拟同类（NOAK）工厂设备配置。对FOAK研究中的组件级资本成本进行了缩放和调整，以反映在做过程中的前瞻性学习，以估算NOAK设计的资本成本。发现NOAK工厂的经济绩效对工厂配置和电力输出比例的变化不敏感，但生物质输入比例会显着影响盈利能力。仅消耗碳中性生物质而没有褐煤共同进料的设施具有显着的净负碳排放量，并且在对碳排放量进行定价时具有最有利的预期经济效益。对于这些设施，由于碳排放价格增加到超过120美元/吨，CO 2_{当量所产生的}工厂经济可行性所需的原油价格从100美元/桶迅速下降。。通常，将褐煤与生物质共同燃烧的工厂的利润较低（比100％生物质工厂低），原因是它们的温室气体净排放量较高。
