The broader/commercial impact of this Small Business Innovation Research (SBIR) Phase I project is the development of a molten salt-based carbon capture system that can be applied to a number of different emission sources with easy integration into the existing site. The technology can be applied to hard-to-abate industries such as industrial heat, cement, steel, and hydrogen production, or in hard-to-abate geographies where coal, oil, and natural gas are likely to remain prevalent fuels for decades. The technology can also support carbon dioxide removal from biogenic sources. Net-negative emissions can be achieved in sectors such as pulp and paper, waste-to-energy, and bioenergy. The molten borate carbon capture technology can be used to decarbonize heavy industry by capturing carbon dioxide at the source. These industries dominate global carbon dioxide emissions emitting over 23 billion tons per year, a greater than $1 trillion market at $50 per ton of carbon dioxide. The advancement of this molten borate carbon capture technology could have the potential to decrease the costs of carbon dioxide capture by solving the efficiency penalty associated with high temperature separations in carbon capture. The intellectual merit of this SBIR Phase I project resides in the discovery of a molten borate composition that can reduce the cost and increase the design flexibility of future carbon capture systems. The addition of other metals and or changes to the mixing ratio are expected to lead to reductions in melting point and the ultimate working temperature of a system where these salts are employed. This research aims to probe this unexplored phase space by synthesizing and testing an array of salt compositions that have modified alkali metal and mixing ratio content compared to the reference. Reductions in molten borate melting point have the potential to mitigate freezing concerns and reduce upper material temperatures, ultimately decreasing the cost, and increasing the potential for widespread adoption of this novel carbon capture technology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小企业创新研究 (SBIR) 第一阶段项目的更广泛/商业影响是开发基于熔盐的碳捕获系统，该系统可应用于多种不同的排放源，并且可以轻松集成到现有站点中。该技术可应用于工业供热、水泥、钢铁和制氢等难以减排的行业，也可应用于煤炭、石油和天然气可能在几十年内仍是普遍燃料的难以减排的地区。该技术还可以支持从生物源中去除二氧化碳。纸浆和造纸、垃圾发电和生物能源等行业可以实现净负排放。熔融硼酸盐碳捕集技术可通过从源头上捕集二氧化碳来实现重工业脱碳。这些行业主导着全球二氧化碳排放量，每年排放超过 230 亿吨，按每吨二氧化碳 50 美元计算，市场规模超过 1 万亿美元。这种熔融硼酸盐碳捕获技术的进步可能通过解决与碳捕获中高温分离相关的效率损失来降低二氧化碳捕获的成本。该 SBIR 第一阶段项目的智力优势在于发现了一种熔融硼酸盐组合物，该组合物可以降低成本并提高未来碳捕获系统的设计灵活性。 添加其他金属和/或改变混合比预计会导致使用这些盐的系统的熔点和最终工作温度降低。本研究旨在通过合成和测试一系列盐组合物来探索这个未探索的相空间，这些盐组合物与参考相比具有修改的碱金属和混合比含量。熔融硼酸盐熔点的降低有可能减轻冻结问题并降低上部材料温度，最终降低成本，并增加广泛采用这种新型碳捕获技术的潜力。该奖项反映了 NSF 的法定使命，并被认为是值得的通过使用基金会的智力优势和更广泛的影响审查标准进行评估来提供支持。
