We have developed a computational method to discover cost-effective materials for carbon capture and discovered a sorbent that costs 25% less than any other technology while avoiding up to 90% of carbon emissions from a coal-fired power plant.
Short description of your technology
We have developed a computational method to discover cost-effective materials for carbon capture. Using our method, we have identified several new sorbents with lower process costs than state-of-the-art carbon capture materials. Our best sorbent offers a typical 500 MW coal-fired power plant savings of $30 million/year versus the standard sorbent used in pressure-swing adsorption systems. Our technology avoids up to 90% of power plant CO2 emissions, drastically reducing the risks associated with severe climate change. In addition to carbon capture, our method opens vast possibilities for applications in other industrial separations including air separation, ethylene and propylene production, natural gas purification (CO2, methane), hydrogen recovery, and xylene separation.
What is the key element of your technology that differentiates it from existing solutions
Our approach is unique in that it combines material selection and process optimization to screen databases of zeolites and metal-organic frameworks for sorbents that satisfy design constraints with minimum process cost. We have demonstrated that considering either the material or process in isolation is insufficient to obtain the most cost-effective solution. In addition to identifying the best material, we have determined an optimal process design that recovers at least 90% of CO2 from power plant exhaust with at least 90% purity, suitable for pipeline transport, utilization in enhanced oil recovery, or geological sequestration. Our computational approach is general and can be applied to any molecular separation to discover cost-effective materials.
Eric First is a fourth-year Ph.D. student in the Department of Chemical and Biological Engineering at Princeton University and a National Defense Science and Engineering Graduate (NDSEG) fellow. He graduated from Cornell University in May 2009 with a B.S. in Chemical Engineering and Computer Science. Eric joined the Computer-Aided Systems Laboratory in January 2010 where he is advised by Professor Christodoulos A. Floudas. His thesis work focuses on developing algorithms to elucidate physical properties of microporous materials, such as zeolites and metal-organic frameworks, by studying the geometry of their underlying crystal structures. His research is driven by the goal of discovering novel materials for applications in separations and catalysis.
