New research shows how a shipboard system using limestone and seawater could cut maritime CO2 emissions by 50%.
New research shows how a shipboard system using limestone and seawater could cut maritime CO2 emissions by 50%.
Scientists at USC and Caltech, in collaboration with startup company Calcarea, have developed a promising shipboard system that could remove up to half of carbon dioxide emitted from shipping vessels by converting it into an ocean-safe solution.
The breakthrough, described in Science Advances, describes how the system could reduce carbon emissions from the shipping industry — one of the world’s most difficult-to-decarbonize sectors.
“What’s beautiful about this is how simple it is,” said William Berelson, the Paxson H. Offield Professor in Coastal and Marine Systems at the USC Dornsife College of Letters, Arts and Sciences and co-corresponding author of the study. “We’re speeding up a process the ocean already uses to buffer CO2 — but doing it on a ship, and in a way that can meaningfully reduce emissions at scale.”
