Swiss technology group ABB has deepened its collaboration with Swedish nuclear developer Blykalla, signing a new memorandum of understanding (MoU) to accelerate the adoption of small modular reactors (SMRs) in the shipping sector. This expanded agreement builds upon a previous deal focused on energy grid applications, now specifically targeting maritime uses for Blykalla’s Swedish Advanced Lead Reactor (SEALER) technology.
Key Takeaways
- ABB and Blykalla are enhancing their partnership to advance nuclear propulsion for ships.
- The collaboration focuses on Blykalla’s compact, 55 MWe SEALER SMR, designed with passive safety features.
- ABB will contribute expertise in electrification, power distribution, control, and automation systems for maritime SMR integration.
- This move aligns with the International Maritime Organization’s efforts to update safety codes for nuclear merchant ships to include SMRs.
Advancing Maritime Nuclear Technology
The renewed collaboration between ABB and Blykalla signifies a significant step towards integrating nuclear power into the maritime industry. The SEALER SMR, a compact 55 MWe unit, is recognized for its passive safety features and minimal operator intervention requirements. It was previously identified by the Nuclear Propulsion for Merchant Ships I (NuProShip I) project as a suitable candidate for large vessel deployment.
ABB’s role will be crucial in providing integration expertise across various critical systems, including electrification, power distribution, control, and automation. This partnership aims to leverage SMRs as a potential solution for decarbonizing the shipping industry.
Global Momentum for Nuclear Shipping
The announcement comes at a time of increasing global interest in nuclear propulsion for shipping. The International Maritime Organization (IMO) is actively working on revising the Code of Safety for Nuclear Merchant Ships to accommodate new technologies like SMRs, which were not covered in the original code. Member states supported these revisions at the MSC 110 session.
Jacob Stedman, CEO of Blykalla, expressed enthusiasm for the collaboration, calling it a "critical building block" for leading the way in maritime nuclear propulsion. Juha Koskela, president of ABB’s marine and ports division, highlighted the potential of SMRs to drive decarbonization and the partnership’s role in advancing their maritime viability.
Several other industry players are also exploring nuclear power for shipping. HD Hyundai, in partnership with TerraPower, has developed a containership concept powered by SMRs, receiving approval in principle. Samsung Heavy Industries is also working on a nuclear-powered gas carrier design. Furthermore, initiatives like the formation of the Nuclear Energy Maritime Organization (NEMO) and the exploration of floating nuclear power plants underscore the growing commitment to nuclear-powered shipping solutions.
