Capture of CO2 by Hybrid Sorption (CACHYS) for Existing Coal-Fired Plants

This Small Business Innovation Research (SBIR/STTR) project targets the development of a novel technology for CO2 capture and separation from combustion-derived flue gas. In the US, coal-fired power plants represent about 50% of the electricity generated but contribute about 80% of the CO2 emissions. CO2 emissions are responsible for climate change. The Department of Energy is supporting development of technologies that will decrease the cost of capturing and sequestering CO2 emission from power plants. A novel CO2 capture and separation technology is proposed that is projected to significantly lower the cost and minimize the energy penalty of CO2 capture. In Phase I, we will evaluate novel sorbents and methods of use of these sorbents to capture CO2in a bench-scale test facility and confirm the unique performance-enhancing aspects of our technology. In Phase II, sorbents that have exhibited superior performance in bench-scale testing will be further tested. A slipstream of a coal-fired boiler exhaust will be used with a tailored contacting device to evaluate the performance of the selected sorbents for CO2 capture in Phase II. Commercial Application and Other Benefits: A successful demonstration of our technology can significantly reduce the cost and energy penalties associated with CO2 capture and separation from combustion and power plant flue gases. Implementation of the technology would be a step in reducing global warming and climate change due to anthropogenic CO2 emissions.
