Captured CO is a potential feedstock to produce fuel/chemicals using renewable electricity as the energy source. We explored resource availability and synergies by region in the United States and conducted cost and environmental analysis to identify unique opportunities in each region to inform possible regional and national actions for carbon capture and utilization development. This study estimated production cost of synthetic methanol and Fischer-Tropsch (FT) fuels by using CO captured from the waste streams emitted from six industrial [ethanol, ammonia, natural gas (NG) processing, hydrogen, cement, and iron/steel production plants] and two power generation (coal and NG) processes across the United States. The results showed that a total of 1594 million metric ton per year of waste CO can be captured and converted into 85 and 319 billion gallons of FT fuels and methanol, respectively. FT fuels can potentially substitute for 36% of the total petroleum fuels used in the transportation sector in 2018. Technoeconomic analysis shows that the minimum selling prices for synthetic FT fuels and methanol are 1.8-2.8 times the price of petroleum fuel/chemicals, but the total CO reduction potential is 935-1777 MMT/year.
捕获的 CO 是一种潜在的原料,可以利用可再生电力作为能源来生产燃料/化学品。我们通过地区探索了美国的资源可用性和协同作用,并进行了成本和环境分析,以确定每个地区独特的机会,为可能的碳捕获和利用发展的区域和国家行动提供信息。本研究估计了通过从美国六个工业(乙醇、氨、天然气(NG)加工、氢气、水泥和钢铁生产厂)和两个发电(煤和 NG)过程排放的废物流中捕获的 CO 生产合成甲醇和费托(FT)燃料的生产成本。结果表明,总共可以捕获和转化 15.94 亿吨/年的废 CO,分别转化为 850 亿加仑和 3190 亿加仑的 FT 燃料和甲醇。FT 燃料有可能替代 2018 年交通运输部门使用的总石油燃料的 36%。技术经济分析表明,合成 FT 燃料和甲醇的最低销售价格是石油燃料/化学品价格的 1.8-2.8 倍,但总 CO 减排潜力为 935-1777 百万吨/年。
