Onboard carbon capture and storage (OCCS) could play an important role as an interim measure for shipping decarbonization while alternative fuels are scaled up, it was heard at a recent seminar organized by the International Maritime Organization (IMO).

Emerging as a potential technology to reduce greenhouse gas (GHG) emissions from shipping, OCCS applies carbon capture and storage (CCS) technology directly on ships. It captures CO₂ emissions before they enter the atmosphere, stores them temporarily on board ships and later offloads them for transport for utilization or permanent storage.
