Carbon Herald: Calcarea’s Unique Approach Captures CO2 From Ships And Sequesters It Directly Into The Ocean

A unique CO2 capture and removal technology is redefining the boundaries of the carbon capture industry, acting as an efficient approach to eliminating the emissions of the hard-to-abate shipping industry.

Caltech-founded, Calcarea is a carbon-sequestration start-up developing a revolutionary technology that captures ship-board carbon dioxide and converts it to safe, durable ocean salts. 

The process mimics the earth’s natural oceanic carbon cycle – excess CO2 with CaCO3 in the ocean forming bi-carbonate (durable form of carbon) but shortens this cycle that takes over millennia. 

Calcarea also just announced it has signed a collaboration agreement with Lomar’s corporate venture lab, lomarlabs, to develop Calcarea’s technology that captures CO2 from ship-board exhausts, and converts it into stable, benign ‘bicarbonate’ ions that could be directly and safely released into the ocean.
