- Carbon Ridge has successfully deployed its centrifugal onboard carbon capture system (OCCS) aboard Scorpio Tankers’ LR2 product tanker, marking a major milestone in maritime decarbonization.
- The modular and compact OCCS design reduces capital and operational costs while enhancing capture efficiency and enabling flexible installation on existing or new vessels.
- Backed by over $20M in funding, Carbon Ridge offers a scalable and regulation-ready solution for shipowners to meet climate targets without overhauling propulsion systems.
Carbon Ridge, a leading developer of onboard carbon capture and storage (OCCS) systems, has reached a significant industry milestone with the first successful deployment of a centrifugal carbon capture unit on a commercial vessel. The installation was carried out aboard the STI SPIGA, an LR2 product tanker operated by Scorpio Tankers Inc., a major player in refined petroleum product shipping. This pilot project, launched in July at Turkey’s Besiktas Shipyard, represents a pioneering moment in the commercialization of advanced OCCS technologies for maritime use, according to Marine Link.
Compact and Cost-Efficient Technology for Real-World Shipping
Carbon Ridge’s OCCS system features a modular design that minimizes both upfront capital expenditure and ongoing operational costs. Its compact form factor reduces space usage by up to 75% compared to traditional OCCS columns, allowing for easier integration into the tight confines of marine vessels. The system can be installed either vertically or horizontally, offering flexibility across a wide range of ship types and layouts. Captured CO₂ is compressed, liquefied, and safely stored onboard throughout the voyage, ready for offloading at port.
Flexible, Future-Ready Decarbonization for Shipowners
The centrifugal OCCS solution is designed for both retrofit and newbuild applications, requiring no major changes to propulsion systems. This allows shipowners and charterers to integrate emissions reduction capabilities across diverse fleets and fuel types. Carbon Ridge’s approach delivers a scalable and future-proof tool for compliance with evolving maritime decarbonization regulations while avoiding disruption to existing vessel operations.
End-to-End Carbon Compliance Across the Value Chain
Beyond onboard technology, Carbon Ridge also offers a complete logistics solution for captured CO₂, ensuring full compliance with international and regional environmental standards. By combining efficient capture, compact storage, and end-to-end handling, the company is enabling the maritime sector to take a practical step toward net-zero targets.
Funding Secured for Commercial Scale-Up
To accelerate its technology deployment, Carbon Ridge recently closed an additional funding round led by Katapult Ocean and Alfa8, with continued support from Crosscut Ventures and Berge Bulk. The company has now secured over $20 million in total investment, positioning it to scale operations and expand its impact in the global shipping industry.
The successful OCCS pilot on Scorpio’s tanker demonstrates that centrifugal carbon capture technology is not only viable at sea but also ready for broader industry adoption. Carbon Ridge’s flexible, compact, and cost-effective solution gives shipowners a powerful new option in their decarbonization toolkit as regulations tighten and pressure mounts to reduce emissions across the maritime sector.
