Onboard Carbon Capture for Shipping
Coverage from SMI Digital, SAFETY4SEA, and others
Onboard carbon capture and storage is being examined as a way for commercial ships using conventional or transitional fuels to reduce tank-to-wake emissions.
Systems vary from mature amine-based post-combustion designs to newer approaches, with demonstrations including Solvang’s Clipper Eris and projects involving companies such as Carbon Ridge, Seabound, and Value Maritime. Deployment depends not only on capture rates and energy penalties, but also on ship space, CO2 purity, port reception, permanent storage, and reliable accounting. IMO standards and the treatment of captured emissions under EU ETS and FuelEU Maritime are therefore central to whether OCCS can move beyond selected vessels and routes.
