Onboard carbon capture and storage systems (oCCS) could play a significant role in helping shipping reduce CO2 emissions, while alternative fuel supply chains continue to develop, according to a new Lloyd’s Register (LR) report.
The report, Applying Onboard Carbon Capture & Storage to Existing Ships, comes as shipowners face increasing pressure to decarbonise and reduce CO₂ emissions. Only around 4% of the near-zero GHG emission fuel production capacity needed by 2030 has reached final investment decision. Alternative fuel-capable vessel orders have also fallen from 45% of contracted tonnage in 2024 to 37% in 2025.
Against this backdrop, the report argues that much of the fleet on order or in service today will continue to rely on conventional petroleum fuels well into the 2030s. For these vessels, oCCS offers an additional route to reducing CO₂ emissions alongside alternative fuels and energy efficiency technologies.
The research finds that specific oCCS technologies have moved beyond the concept stage and are
