About

Carbon Ridge develops modular Onboard Carbon Capture & Storage (OCCS) systems for large maritime vessels, enabling ships to capture over 90% of CO2 emissions directly from exhaust gas while eliminating 99.9% of particulate matter, NOx, and SOx. The centrifugal capture technology is designed for both retrofit and newbuild applications, offering shipping operators a near-term compliance pathway for IMO decarbonization targets without requiring alternative fuels or major vessel conversions. Carbon Ridge completed the first commercial installation of its OCCS system aboard the STI Spiga tanker.
