About this episode

Omar Sadoon discusses the role of alkalinity in carbon removal and the challenges of ocean alkalinity enhancement.

Is all of carbon removal really just about alkalinity? There's a case to be made for quite a lot of it. Weathering, ocean alkalinity enhancement, even parts of direct air capture—they all come back to manipulating pH and moving basic materials to where they can cancel out excess acid in the atmosphere and ocean. Omar Sadoon is the Director of Strategic Partnerships at Planetary Technologies, an ocean alkalinity enhancement company working to remove carbon by adding carefully-sourced alkaline materials to the ocean. Listen in to hear about the enormous logistical and scientific puzzle of finding the right alkalinity sources, getting them to the right ocean sites without breaking the LCA, and the lessons learned from Planetary's Cornwall and Tufts Cove projects. It's a show about community engagement, the surprising value of relationships in carbon removal sales, humor, and how Omar's background as a mental health nurse shaped his approach to partnership building.
