Sustainable and Negative Carbon Footprint Solid-Based NaOH Technology for CO2 Capture

We report a highly efficient system for CO2 capture and conversion to a green solid carbonate that utilizes solid NaOH. This novel technology has important advantages over the currently available technologies regarding percent of CO2 capture, heat production, and carbonate yields. The study uses a techno-economic analysis as a quantitative tool in the valuation of CO2 capture for an environmental and economic gains objective. We highlight two important advantages of this technology that go hand in hand with a sustainable development: low economic cost and negative energy and carbon footprint.
