Carbon Ridge's OCCS Achieves 98% CO2 Capture Rate in Maritime Pilot
DNV has validated Carbon Ridge's centrifugal onboard carbon capture system, achieving a peak CO2 capture rate of 98%. This pilot project, conducted on the STI Spiga vessel, represents a significant advancement in maritime carbon capture technology.

Carbon Ridge's centrifugal onboard carbon capture system has been confirmed by DNV to reach peak CO2 capture rates of 98%. The pilot project took place on the STI Spiga, a 109,999 dwt tanker, during a five-month evaluation that started in July 2025 at Besiktas Shipyard, Turkey.
DNV's assessment validated methodologies and performance metrics, reporting that 55% of data observations fell within 86-98% capture rates. The OCCS technology is compact, requiring 75% less space than traditional systems, and can be installed flexibly.
The successful validation positions Carbon Ridge for scaling OCCS across the maritime industry. Continued collaboration with Scorpio Tankers Inc. will be crucial for future advancements and real-time performance assurance.
