摘要21世纪世纪能源生产、转换和输送系统需要在满足日益增长的能源需求的同时，向低碳密集型转变。在一个越来越相互关联的世界，能源系统的各个部门（如电力，燃料，化学品等）。通过将主要能源从碳密集型化石燃料转向可再生和可持续资源来实现这一过渡。通过这项研究，我们提出了一种多尺度策略，用于多产品过程系统的优化设计和操作，该系统可以从可再生资源和化石资源中生产电力，合成燃料，化学品和能源载体。这种多尺度方法将过程综合、调度和供应链概念结合到混合整数线性规划模型中，以解决集成各种化石和可再生技术之间的权衡问题。我们的战略适用于低排放的整合（i）合成液体运输燃料，（ii）氢，（iii）氨，（iv）甲醇，（v）天然气，太阳能和风能的可再生能源生产在阿马里洛，得克萨斯州的位置。案例研究结果表明，与我们的方法，各种能源系统可以单独建模，并与相同的共同表示集成。在同一设施中生产低排放产品的部门整合可使总生产成本降低17%。虽然太阳能和风能有利于生产可再生能源，但目前最先进的甲烷转化技术更有利于生产氢气和氢基产品。
Abstract 21 st century energy production, conversion, and delivery systems need to go through a transition to be less carbon-intensive while meeting an increasing energy demand. In a more and more interconnected world, energy systems of various sectors (eg power, fuels, chemicals, etc.) go through this transition via shifting the primary energy sources from carbon-intensive fossil-fuels to renewable and sustainable resources. With this study, we present a multi-scale strategy for optimal design and operation of multi-product process systems that can produce power, synthetic fuels, chemicals, and energy carriers from renewable and fossil resources. This multi-scale approach combines process synthesis, scheduling, and supply chain concepts in a mixed-integer linear programming model to address the trade-offs between integrating various fossil and renewable technologies. Our strategy is applied to integration of low-emission (i) synthetic liquid transportation fuels,(ii) hydrogen,(iii) ammonia,(iv) methanol, and (v) renewable power production from natural gas, solar, and wind energy at a location in Amarillo, Texas. Case study results show that with our approach various energy systems can be modeled either separately and integrated with the same common representation. Sectors integration to produce low-emission products in the same facility can result in 17% reduction in total production costs. While solar and wind energy are favorable to produce renewable power, current state-of-the-art methane conversion technologies are more favorable to produce hydrogen and hydrogen-based products.
