The broader/commercial impact of this Small Business Innovation Research (SBIR) Phase I project is in potentially contributing to the creation of a viable gigaton-scale Direct Air CO2 (carbon dioxide) Capture (DAC) technology. The technology could be a key pillar in preventing the worst effects of climate change. For over a century, humanity has emitted billions of tons of CO2 into the atmosphere each year. As more CO2 has accumulated in the atmosphere trapping the sun’s rays, Earth’s temperature has continued to rise. According to the Bipartisan Policy Center, gigaton-scale DAC stands to support the creation of a trillion-dollar industry in the United States and underpin the development of 3 million jobs. This project is based on a novel DAC design addressing two key hurdles to achieving the scale needed to effectively offset CO2-caused climate change: cost to build infrastructure and energy to run processes. The system injects carbon capture fluid with a monoethanolamine (MEA) spray and removes that spray with an exhaust particle separating centrifuge. Through this hollow design, it not only saves on building costs, but may be poised to save on ongoing energy costs. Energy cost in a carbon capture contactor is a function of pressure drop or drag. The company's hypothesis is that a centrifuge is significantly more aerodynamic than the honeycomb-like filling currently used in contactors. The energy savings can translate into a system with significantly lower pressure drop and, therefore, lower ongoing energy costs to run. The program is organized into research objectives that investigate each area of technical risk. The first objective is calculating the optimal fluid particle size for capturing carbon dioxide from the air and optimizing the MEA operating range within the proposed system through Computational Fluid Dynamics (CFD) and lab testing. The second objective is determining the relationship between the fan and centrifuge through physical prototyping. The third objective is designing the facility shape itself though a mix of CFD and physical prototyping.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.

该小型企业创新研究 (SBIR) 第一阶段项目的更广泛/商业影响可能有助于创建可行的十亿吨级直接空气二氧化碳捕获 (DAC) 技术，该技术可能成为关键支柱。为了防止气候变化的最严重影响，一个多世纪以来，人类每年向大气中排放数十亿吨二氧化碳，随着更多的二氧化碳在大气中积累，地球的温度持续上升。两党政策中心表示，十亿吨规模的 DAC 将支持在美国创建一个价值数万亿美元的产业，并支撑 300 万个就业岗位的发展。该项目基于新颖的 DAC 设计，解决了实现这一目标的两个关键障碍。有效抵消二氧化碳引起的气候变化所需的规模：建设基础设施和运行过程所需的能源成本该系统通过单乙醇胺（MEA）喷雾注入碳捕获液，并通过废气颗粒分离离心机去除喷雾。它不仅节省了建筑成本，而且可能会节省持续的能源成本。碳捕获接触器的能源成本是压降或阻力的函数。该公司的假设是，离心机比蜂窝式离心机更具空气动力性。就像目前接触器中使用的填充一样，节省的能源可以转化为压降显着降低的系统，从而降低持续运行的能源成本。目标是计算流体最佳粒径从空气中捕获二氧化碳，并通过计算流体动力学 (CFD) 和实验室测试优化拟议系统内的 MEA 运行范围。第二个目标是通过物理原型确定风扇和离心机之间的关系。通过 CFD 和物理原型的结合来塑造自己。该奖项反映了 NSF 的法定使命，并且通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
