Carbon Ridge has reported that its onboard carbon capture and storage (OCCS) technology achieved CO2 capture rates of up to 98% during a shipboard trial independently assessed by DNV.
The five-month pilot was carried out aboard the LR2 product tanker STI Spiga, owned by Scorpio Tankers, with the system capturing a portion of the vessel’s exhaust emissions while it remained in normal commercial service.
Using its Recommended Practice for OCCS verification, DNV reviewed the trial data and confirmed peak capture rates above 98%, while more than half of recorded observations showed capture performance ranging from 86% to 98%.
The trial is significant because it represents the first maritime application of a centrifugal carbon capture system, a technology that Carbon Ridge believes could offer shipowners a practical route to reducing emissions from existing vessels.
The company said the modular system is designed to be installed on both newbuild and existing ships, while Scorpio Tankers highlighted its relatively simple installation and limited impact on day-to-day vessel operations.
The results come as the shipping industry explores onboard carbon capture as one of several options for meeting tightening emissions regulations and reducing the carbon footprint of existing fleets.
