HD Korea Shipbuilding & Offshore Engineering Co. (HD KSOE), a subsidiary of Hyundai Heavy Industries, is set to invest up to 300 billion won ($206 billion) in developing small modular reactor (SMR)-powered ships by 2030, with the goal of pioneering carbon-zero shipping. This decision follows the unveiling of the first nuclear-propelled container ship model by Hyundai Heavy Industries, signaling a shift towards cleaner energy systems in the marine transportation sector. The investment will be allocated towards developing SMRs for vessel propulsion, hydrogen fuel cells for both land power grids and ships, with the expectation that nuclear-powered vessels will lead the way in adopting cleaner energy sources. SMRs, particularly the molten chloride fast reactor (MCFR), are seen as a promising alternative due to their compact size, extended life cycle, and space efficiency compared to traditional ships. Furthermore, the investment aims to bridge the technological gap with Chinese shipbuilders, who have been rapidly gaining ground in the global market. Despite the potential of SMR technology, cost and safety issues remain significant challenges, with estimates of hundreds of billions of won needed to develop a 70-MW SMR for ships. HD KSOE's initiative is seen as a strategic move to stay ahead in shipbuilding technology and drive the industry towards a more efficient and environmentally friendly future.
