In this episode of Catching Carbon, we dive into a carbon removal method that's moving fast from theory to large-scale deployment: enhanced rock weathering (ERW). Our guest, Ryan King from UNDO, walks us through the science, economics, and real-world application of this XPRIZE-recognized technology. Ryan helps us understand why enhanced rock weathering is gaining serious traction: - What it is: a natural process of CO₂ removal from the atmosphere that we’ve learned how to speed up by 100,000 times using finely crushed silicate rock. - XPRIZE recognition: UNDO placed as a third runner-up in the $100M XPRIZE Carbon Removal competition, beating out thousands of entrants with their scalable approach. - Start with nature: The process builds on natural rock weathering, which has been pulling CO₂ from the atmosphere for millions of years. - Faster, smarter, verified: By crushing rock and spreading it across farmland, the surface area and reactivity increase dramatically—making the process far more efficient. Carbon capture is tracked, measured, and verified, with UNDO’s IP pending patent based on measuring CO₂ absorption via soil water content. - Added benefit: ERW also acts as a natural soil enhancer, providing benefits for agriculture beyond just climate impact. - Farmer incentives: It can replace liming, potentially reducing costs for farmers while supporting regenerative practices. - Commercialization strategy: Ryan outlines how UNDO is moving beyond research and into large-scale deployment, targeting gigaton-scale impact. - Rock of choice: Among many candidates, UNDO has identified the best-performing rock for both reactivity and carbon permanence. - Retention rate: They’re achieving 90% efficiency in terms of retaining captured carbon versus what’s potentially re-emitted. https://un-do.com

In this episode of Catching Carbon, we sit down with Josh Raglin, Chief Sustainability Officer at Norfolk Southern Corporation, one of the largest freight railroads in North America. With over two decades of experience in nature-based sustainability solutions, Josh shares how Norfolk Southern is leading the charge to decarbonize rail transport and improve ecosystem health—far beyond the tracks. The conversation kicks off with Norfolk Southern’s groundbreaking partnership with Remora to test mobile carbon capture technology on locomotives, aiming for a potential 70% CO₂ reduction. But this episode goes well beyond carbon capture.

We also explore how railroads are collaborating across the industry—sharing test results, technologies, and strategies—as they prepare for a lower-carbon future. This is a rare behind-the-scenes look at the cutting edge of rail innovation and sustainability. Whether you're in logistics, energy, climate tech, or CO₂ utilization, this episode offers a powerful vision of what’s possible when legacy infrastructure meets next-gen thinking.

What if the key to solving carbon emissions was hidden in plain sight—floating all around us in our oceans? In this episode of Catching Carbon, we sit down with Garrett Boudinot, Founder and CEO of VYCarb, to dive into a new frontier in carbon removal: oceanic carbon capture. Garrett shares how VYCarb’s cutting-edge technology is turning the tide on carbon emissions by extracting CO₂ directly from seawater—offering a scalable, nature-inspired solution that could redefine the future of climate tech. Whether you're a climate professional or just carbon-curious, this episode breaks down the science in a way that’s easy to follow and exciting to imagine. We also explore the hot topic of 45Q tax credits and what they could mean for ocean-based capture—can ocean tech finally claim its seat at the table? Tune in for this conversation on innovation, impact, and the massive potential hiding just beneath the surface.
