A Carbon Burial at Sea
Summary
This episode explores carbon removal strategies, starting with an experiment in North Carolina where olivine is dumped into the ocean to accelerate carbon storage. The focus then shifts to Norway, where reporter Sam Baker traces the journey of CO2 captured from a cement plant to its underground storage under the North Sea via the Northern Lights project. The discussion highlights the technology's high costs, operational challenges, and criticisms regarding fossil fuel companies using carbon capture to prolong extraction rather than transition to renewables.
