HD Hyundai 3 Strategic Partnerships for SMR Commercialization (2025 to 2026)

The formation of a viable ecosystem through strategic partnerships is the most critical enabler for commercializing maritime nuclear power. Prior to 2025, development efforts were largely siloed within individual technology companies. The recent trend shows a convergence of shipbuilders, reactor developers, engineering firms, and classification societies to solve systemic challenges related to regulation, manufacturing, and integration.

• The agreement between HD Hyundai and Terra Power in October 2025 is a cornerstone partnership. It connects one of the world’s largest shipbuilders with a leading advanced reactor developer to establish a manufacturing supply chain for commercializing the Natrium reactor technology.
• In September 2025, the collaboration between global engineering firm ABB and Swedish reactor developer Blykalla was formed to specifically develop nuclear power technology for the maritime industry, focusing on system integration.
• Recognizing the primary hurdle of regulation, classification society Lloyd’s Register began leading a UK-based consortium in January 2026. This initiative is dedicated to creating the global standards and rules necessary for the safe and commercial operation of nuclear-powered ships.

Asia vs. Europe, Maritime Nuclear Leadership and Regulatory Development

A distinct geographic division of labor has emerged in the pursuit of maritime nuclear propulsion. While Europe, particularly the UK, is taking the lead in developing the crucial international regulatory and legal frameworks, Asia, led by South Korea, is focusing on the industrial and manufacturing capabilities required to build the first generation of commercial nuclear vessels.

• The UK’s leadership in regulation is demonstrated by the Lloyd’s Register-led consortium launched in 2026. This effort aims to create the global standards that are a prerequisite for insurance, financing, and port access, positioning the UK as a key rule-maker for the sector.
• South Korea’s HD Hyundai has established itself as the industrial frontrunner. Its partnership with US-based Terra Power and its active development of a nuclear-powered container ship design show a clear focus on manufacturing and commercial application.
• The United States contributes significantly through its technology developers like CORE POWER and Terra Power, and its robust naval nuclear supply chain exemplified by companies like BWXT. This provides a deep reservoir of technical expertise and manufacturing experience.

SMR Technology Readiness, from TRL 6 Validation to First Commercial Orders

The maturity of maritime nuclear technology has progressed from a validation stage to a pre-commercialization phase.
