264. The XPRIZE Winner Pumping Antacid Into the Ocean w/ Mike Kelland

Today, Matt speaks with Mike Kelland, Co-founder & CEO of Planetary, about using the ocean to pull carbon dioxide out of the air. Planetary adds calcium and magnesium minerals, basically an antacid, to water flowing out of coastal facilities. That lowers local acidity and lets the ocean absorb more CO2 from the atmosphere.

Mike breaks down the UN's new Limiting Overshoot report, which he says puts the carbon removal we need at about 23 gigatons a year, and explains why trees, machines and every other land-based approach top out around 15, leaving the ocean to close the gap. He and Matt also get into the safety question people are afraid to ask, how Planetary's Halifax plant reached 8,000 tons removed, why compliance carbon markets are the key to scaling, and the all-hands, middle-of-winter push that won Planetary an XPRIZE.
