## Summary

Rob van Straten, CEO of Skytree, explains how the company pivoted from an automotive CO2 scrubber concept to building modular Direct Air Capture (DAC) systems for vertical farms and large-scale carbon removal parks. He details Skytree’s strategy of mass-producing transportable units to drive down costs and enable rapid iteration, contrasting this with the site-based approach of competitors like Climeworks. Van Straten discusses the technical challenges of sorbent lifetime, the shift to vacuum-based temperature swing adsorption, and the importance of integrating waste heat to minimize the carbon footprint of the capture process.
