The Koreans published the fourteenth issue of their Carbon Reduction Magazine (KR Decarbonization Magazine) on October 29, 2026. This issue examines emerging regulatory frameworks for small marine reactors (SMR) and discusses the challenges associated with installing these reactors on ships and safety approvals.
Regulatory Analysis and Technological Challenges
This issue begins with an overview of the regulatory frameworks for small marine reactors and includes the challenges of installing these reactors on ships. These challenges include ensuring safety, maintenance requirements, and the costs and complexities of obtaining approvals. The article also reviews recent work on revising IMO regulations, IMO-IAEA collaboration, and KR's own technical projects.

Meanwhile, while the regulatory framework for small marine reactors is still being developed, the FuelEU Maritime program has been fully implemented, and this magazine analyzes its first year of compliance. According to KR's analysis, ships that fail to comply with mandatory greenhouse gas intensity limits can avoid penalties by aggregating their compliance balances with ships that have high compliance. Nearly 92% of ships utilized this aggregation in the first year, while the excess compliance price gradually decreased to about 80% below the penalty level.
Innovative Technologies and Engine Optimization
This issue also includes an interview with Minho Kang, Senior Vice President at HD Hyundai Heavy Industries, discussing engine optimization technologies and exhaust gas treatment systems. He talks about the Methane Oxidation Catalytic System (MOCS) that oxidizes unburned methane emitted from LNG engines.
Dr. Kang Hyun Seong, Head of Ship and Carbon Reduction Platform Research, stated: "Delays in adopting the IMO carbon-neutral framework have created uncertainty regarding green technologies. However, EU regulations are currently in effect, and shipowners and financial institutions continue to stimulate demand for carbon reduction. Instead of waiting for regulatory clarity, shipowners should maintain flexibility and strengthen their carbon reduction strategies."
