Jess Adkins

Jess Adkins is a Caltech chemical oceanographer turned founder-CEO of Calcarea, a climate-tech startup that bolts a limestone-and-seawater reactor onto cargo ships to scrub up to half their CO2 and lock it away as ocean bicarbonate. After two decades studying how the deep ocean naturally buffers carbon, he spun his lab science out of the garage during COVID to attack shipping's gigatonne-a-year emissions problem at a fraction of the cost of atmospheric capture.
