A new analysis from Lloyd’s Register, LucidCatalyst and Seaspan argues that nuclear propulsion could deliver major cost savings while removing greenhouse gas emissions from large containerships. The research identifies clear commercial advantages alongside a pathway for safe deployment.
A new industry report from Lloyd’s Register and LucidCatalyst for Seaspan points to the economic and environmental potential of using small modular reactors to power large containerships. The analysis suggests that nuclear propulsion could remove bunker fuel costs, eliminate emissions and improve vessel performance without compromising safety or competitiveness.
According to the findings, a nuclear powered 15,000 TEU vessel operating at 25 knots could complete more voyages each year compared with conventional ships. The higher speed would allow an estimated 6.3 round trips annually rather than five. With no fuel tanks on board, the ship could gain about five per cent additional container capacity. Combined, this represents up to 38 per cent more annual cargo capacity.
The report estimates that a vessel operator could avoid up to fifty million dollars in bunker costs each year, along with around eighteen million dollars in carbon penalties. It also sets out how a wider build programme could bring down technology costs if industry commits to a large order pipeline. This includes the potential to produce modular reactors for between seven hundred and fifty and one thousand dollars per kilowatt if more than one thousand units are ordered within a ten to fifteen year window.
Meg Dowling, Senior Engineer for Nuclear Technology and Alternative Fuels at Lloyd’s Register, said: “The energy transition and long-term sustainability challenges of shipping demands long-term solutions that can scale. Nuclear propulsion offers not just a decarbonised solution, but a transformative economic opportunity for shipowners and charterers alike. The results of this research give us a strong foundation to define how systems can be integrated within the commercial fleet to provide a credible pathway towards safe, commercially viable, zero-emission shipping.”
Seaspan’s Chief Technology Officer, Peter Jackson, said: “As part of our ongoing efforts to find safe and commercially viable energy transition pathways, we have partnered with LR and Lucid Catalyst to explore nuclear propulsion for containerships. Small Modular Reactors (SMR’s) is a very exciting technology offering several desirable benefits for shipowners and operators, as outlined in this report. Naturally there are challenges to overcome, but I am confident that ongoing work in this area and studies like this will soon allow nuclear powered containerships to be operating safely, economically, and emission free.”
Eric Ingersoll, Managing Partner at LucidCatalyst, said: “Nuclear propulsion transforms shipping economics, not just emissions. Our analysis shows that nuclear-powered containerships will likely outcompete conventionally fuelled and green fuelled competitors—dominating their trading routes through superior performance without requiring green premiums.”
The report forms part of a larger programme that will next examine concept design and regulatory readiness. A final stage will map out risk management, certification and investment pathways for large scale deployment.
