Eye witness: onboard carbon capture and storage

In addition, she noted that energy draw and power-system integration demand constant attention.

“Energy draw and integration into existing power systems need close attention. The crew noted maintenance routines were still being refined, and system monitoring required frequent checks – though automation is improving.”

Despite these hurdles, Ms Sharma believes the lessons learned are widely applicable across tanker sectors.

“Very transferable. Tankers have unique cargo-handling requirements, but the principles of modular design, integration with existing exhaust systems, and port offloading logistics are shared.”

“Key knowledge gaps remain in monitoring and verification protocols, material durability under marine conditions and economic modelling of operating costs, particularly regarding corrosion and solvent degradation at sea,” she said

She confirmed these insights are already shaping Port of Esbjerg’s decarbonisation infrastructure.

“We are ensuring that our CO2 terminal is designed to handle captured CO2 not just from industry – but from ships – including considerations like flexible offloading systems and safety zoning.”

Ms Sharma emphasised the port’s role as the crucial link between captured carbon and permanent storage or reuse, underscoring the need for investment in offloading and interim storage facilities, together with collaboration with classification societies.

Looking ahead, Ms Sharma argued that shipboard capture will serve both as a bridge to zero emissions and as a long-term solution for hard-to-abate voyages.

“I see it as both transitional and long-term. It buys us time on the path to zero emissions, but it will also remain part of the solution where emissions are otherwise unavoidable.”

She added that, with appropriate regulatory support and infrastructure readiness, such systems could become routine on vessels operating on fixed routes or calling at predictable ports.

“With the right regulatory push and infrastructure readiness, shipboard carbon capture could become routine on certain vessel types, especially those on fixed routes or with predictable port access.”
