  Planeteers’ Frank Rattey and Dr. Thorben Amann on closed-system, alkalinity-based carbon removal

  Mar 5, 20261h 5mS3

  <p>In this edition of Plan Sea, hosts Anna Madlener and Wil Burns are joined by Frank Rattey and Dr. Thorben Amann of Planeteers — a Hamburg-based carbon removal startup researching alkalinity-based carbon dioxide removal (CDR) approaches — to discuss the science behind their closed-system pathway, their first field tests, and the national regulations guiding ocean-climate research.</p><p>Dr. Thorben Amann is the Research and Development Lead at Planeteers and a geochemical CDR specialist. In this episode, Thorben explains how Planeteers’ closed-system approach differs from other ocean alkalinity enhancement (OAE) strategies. Rather than dissolving alkalinity directly in the ocean to drive carbon...
