Paul Dunn on The Future of Carbon Capture | Ep.136
Apple Podcasts 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.
