The broader/commercial impact of this Small Business Innovation Research (SBIR) Phase II project stands to contribute to the creation of viable gigaton-scale Direct Air CO2 Capture (DAC), a key pillar in preventing the worst effects of rising CO2 levels in the atmosphere and oceans. Capturing CO2 for permanent sequestration can play a decisive role in mitigating the impacts of rising atmospheric CO2 levels if conducted as part of wider net zero efforts. 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 thousands of jobs. This project is focused on the development of a novel DAC design that addresses two key hurdles to achieving the scale needed to effectively offset the rising CO2 levels for our planet: cost to build the technology and energy to run it. The company’s technology comprises a contactor in which air is pulled in, a chemically reactive spray of amine solvent is injected into a hollow space with no physical media to resist airflow, and a proprietary, low-pressure-drop separator removing spray from the airflow for re-use and subsequent regeneration. Following successful demonstration of the concept at two-meter scale completed during SBIR phase I, the company will test a commercial scale pilot of the system during SBIR phase II. This pilot will include optimized separator build and testing, construction of one commercial contactor module,
