Carbon Ridge has made maritime history with the successful launch of the world’s first centrifugal carbon capture system aboard a commercial tanker, signaling a major step forward in onboard climate technology.
The trial, conducted in partnership with Scorpio Tankers, was installed on the STI SPIGA, an LR2-class product tanker, and began operations this July at Besiktas Shipyard in Turkey.
This breakthrough marks the first time a centrifugal-based carbon capture system has been operational on a vessel at sea, offering a compelling alternative to conventional onboard CO2 capture methods.
Compact Design, Big Impact
Engineered specifically for marine settings, Carbon Ridge’s modular technology features a smaller footprint — up to 75% more compact than traditional systems — making it ideal for retrofits or integration into newbuild ships.
The system captures emissions from the ship’s exhaust, compresses and liquefies the CO2, and stores it safely onboard throughout the voyage.
Because it operates independently of fuel type, it provides shipowners with a flexible, future-proof option as global regulations around maritime carbon emissions continue to tighten.

To support further development and deployment, Carbon Ridge recently secured additional funding in a round led by Katapult Ocean and Alfa8, with support from Crosscut Ventures and Berge Bulk. The company’s total raised capital now exceeds $20 million.
Chase Dwyer, CEO and Founder of Carbon Ridge, stated: “Unlike other CCS solutions, which are designed to be deployed on land and then adapted for ocean operation, we have specifically designed and developed this technology for the maritime industry.”
“The centrifugal carbon capture system is unlike anything that has been deployed on a vessel before and, offers a cost-effective, flexible and modular solution to support the maritime industry in its decarbonization efforts,” Dwyer said.
