Nuclear propulsion: SMRs Poised to Revolutionize Emissions-Free Maritime Shipping

The potential rise of small modular reactors (SMRs) in the maritime industry could revolutionize emissions-free shipping and extend the life cycle of vessels, according to a report by classification society Lloyd’s Register (LR). However, regulatory hurdles must be overcome for widespread commercial adoption, with safety considerations being a key priority. The report highlights the proven track record of nuclear power in naval applications, suggesting that new SMRs could provide low-maintenance reactors to meet the energy needs of commercial ships.

The report emphasizes the need for stringent safety protocols to protect seafarers and the environment, suggesting LR’s Risk Based Certification (RBC) as a possible approach for certifying projects utilizing novel nuclear technology. While technology readiness for nuclear propulsion is improving, public perception and investment levels remain barriers to its widespread adoption in commercial shipping. Despite these challenges, nuclear propulsion could offer significant benefits in terms of decarbonization and increased efficiency for the maritime sector.

NEMO, a recently founded organization focusing on the practical application of new nuclear solutions in the maritime industry, has welcomed three new members. The organization aims to strengthen collaborative efforts in the maritime nuclear sector, further promoting the use of nuclear power in shipping for its potential to provide emissions-free vessels with longer life cycles and minimal refueling infrastructure requirements.
