Climate change regularly appears at or near the top of lists of the greatest challenges of the 21st century and at its core it is a technical issue. However, it attracts attention that is long on partisanship, emotion, and poorly informed commentary and short on proposed practical solutions. This presentation discusses Cryogenic Carbon Capture™ (CCC), a technology that could address a large fraction of this problem at comparatively modest cost. Furthermore, the same technology addresses the greatest challenges in each of renewable and fossil energy supplies.

CCC provides a novel and practical means to separate CO2 from other gases and prepare it for utilization or sequestration. It is practical in the sense that its projected costs and energy demands are each about half of the next-best alternative, though they are still high. It is a retrofittable technology suitable to any continuous CO2 source without modifying or replacing the existing process and in this way distinguishes itself from virtually every other process. It addresses both CO2 removal and energy storage, the major challenges of the fossil and renewable energy communities, respectively.

This presentation steps through the essential process steps and highlights some of the technical challenges and innovations that transform the basic concepts into a practical process. The presentation includes the current status and near-term future opportunities for the process.

Larry Baxter is a professor of chemical engineering at BYU. He came to BYU in 2000 after working at Sandia National Laboratories in Livermore, California, for 14-15 years. He teaches a broad range of chemical engineering classes and does research on sustainable energy systems. He and his wife, Kris, have four children and 11 grandchildren. Some interesting things in his life include (1) Performed on stage to a live audience at Radio City Music Hall, (2) Has been at sea on a nuclear submarine, (3) Attempted (and failed) to navigate the first open-top canoe through Big Kahuna and Lunch Counter rapids, and (4) Led a major international attempt to restore contaminated regions around Chernobyl to productive use.

Prof. Baxter, recipient of the Izatt Christensen Faculty Excellence Award, will deliver a seminar to the Departments of Chemical Engineering and Chemistry and Biochemistry on October 31, 2019 at 4 PM in W140 BNSN. The title of his talk is Climate Change – Novel Solutions to a Global Problem.
