A new report from the International Chamber of Shipping (ICS) says onboard carbon capture and storage (OCCS) can help shipowners meet tightening emissions rules while green fuel availability stays limited. Amine-based systems can capture 70-95% of CO2 from ship exhaust, but space, weight, and port infrastructure remain hurdles. The report points to LNG carriers and large tankers as early candidates due to their operational profiles and available onboard space. Large-scale deployment depends on fixing carbon reception infrastructure at ports and getting clear regulatory credit from the EU ETS, FuelEU Maritime, and the IMO. ICS says OCCS could scale toward the end of the decade if storage pathways and emissions accounting frameworks develop in parallel. The full report is worth a read for anyone tracking maritime decarbonization timelines.
