Abstract
An engineering method termed direct air capture is used to take CO₂, the predominant global warming greenhouse gas, out of the atmosphere directly. Given that CO₂ levels in the air are only 0.04%, it presents a technical challenge. Ambient air has a concentration that is 2-4 orders of magnitude lower than other typically targeted sources for CO₂ capture, like flue gases from energy production and industrial activities. Nevertheless, direct air capture has drawn more attention recently, partly because of the creation and implementation by a small number of start-ups. An increasing quantity of research is being done on novel direct air capture materials and methods, and it’s important to comprehend the costs and environmental effects of direct air capture. The author believes that this engineering tool should be one of many tools utilized in the fight against climate change. This dissertation seeks to gather and analyze critical information on fifteen recently issued United States patents and then synthesize the findings from those fifteen patents and then to optimize the critical components of the patented direct air capture technology to advance the state of the art in carbon removal to ameliorate the impacts of increasing carbon concentrations in the atmosphere.
