Paul Dunn on The Future of Carbon Capture | Ep.136
Capturing CO2 is only half the challenge. On The Energy Pipeline, sponsored by Cat Oil & Gas, host Josh Lowrey sits down with Paul Dunn, Chief Engineer, Low Carbon Solutions at Caterpillar, to explore the technology, economics, and future of carbon capture. Dunn explains Caterpillar’s thermal swing adsorption approach, compares it with other capture technologies, and revisits a 2019 field demonstration. He also discusses 45Q tax credits, carbon monetization in Canada, demand from AI data centers, and a Solar Turbines technique that doubles CO2 concentration while cutting exhaust flow in half. 00:00 Podcast Welcome 00:12 Meet Paul Dunn 01:05 Rhode Island Vs Houston 03:07 Paul’s Engineering Path 06:06 Carbon Capture Options 08:41 Thermal Swing Breakthrough 11:56 Prototype And Acquisition 13:39 Caterpillar Business Model 16:08 Carbon Capture In 2026 17:25 CO2 EOR Explained 20:18 Books And Practicalities 21:32 Where Will CO2 Go 23:06 45Q Credit Gets Real 24:11 Bipartisan Support for CCS 25:35 Canada and Paris Monetization 27:16 From Theory to Deployment 30:23 AI Data Centers Demand Power 33:44 Biggest Barrier: Storage Sites 36:12 Caterpillar Approach Thermal TSA 37:06 Gas Turbine CO2 Concentration Trick 41:01 Scaling Inside Caterpillar 44:53 Wrap Up and Where to Find Them
