Busan is accelerating its position as a global maritime innovation hub. Three major players—Hanwha Group, HMM, and Korean Register—have joined forces to develop revolutionary carbon-free shipping technologies. This collaboration signals serious momentum in the maritime sector’s transition toward environmental sustainability.
🔥 Quick Facts
- MOU signed on October 30, 2025 during KORMARINE 2025 in Busan
- Four Hanwha affiliates participating: Hanwha Power Systems, Hanwha Ocean, Hanwha Aerospace, and others
- Technology focus: Ammonia gas turbines combined with fuel cell propulsion systems
- Development targets include 7,000-8,000 ton container vessels and 2,000 ton feeder ships

The partnership aims to design innovative hybrid propulsion systems that eliminate carbon emissions from marine transport. Ammonia-based gas turbines and fuel cell technology represent the cutting edge of zero-emission vessel propulsion.
The collaboration focuses on container vessels first, which represent approximately 20% of global maritime emissions. By targeting 7,000 to 8,000-ton vessels, the consortium addresses vessels that operate high-volume international trade routes. A separate hybrid system for smaller 2,000-ton feeder ships will enable complete decarbonization across different fleet sizes.

Busan operates as South Korea’s primary shipping port and ranks among the world’s busiest international hubs. The city’s strategic role in global container trade makes it the ideal location for breakthrough sustainable shipping innovation.
Korean Register, the classification authority overseeing ship design and safety standards, provides critical expertise in validating new propulsion technologies. KR’s involvement ensures any carbon-free systems meet international maritime regulations and can achieve commercial viability at scale.
The Technology Behind Carbon-Free Maritime Innovation
| Propulsion Element | Specification | Purpose |
| Ammonia Gas Turbine | Primary propulsion engine | Zero-carbon fuel combustion for main thrust |
| Fuel Cell Technology | Hybrid power system | Supplementary clean energy for operations |
| Target Vessels | 7,000-8,000 ton containers; 2,000 ton feeders | Coverage across international and regional routes |
| Development Phase | Design and concept analysis | Commercial viability testing and validation |
Competitive Advantage: South Korea’s Maritime Innovation Ecosystem
Hanwha Group’s four subsidiaries bring specialized expertise across shipbuilding, power systems design, aerospace engineering, and maritime logistics. This integrated approach accelerates development while ensuring technical excellence across all propulsion system components.
HMM, one of the world’s largest container shipping operators with extensive fleet operational experience, provides critical insight into real-world vessel performance requirements. Their participation ensures designed systems match operational demands of modern international shipping.
“This tripartite agreement aims to advance carbon neutrality in global maritime transportation through the development of innovative propulsion systems.”

What Timeline Should Investors and Shippers Expect?
The consortium has entered the critical design and concept analysis phase, with commercial viability testing as the next major milestone. Full prototype development and real-world testing on demonstration vessels typically require 3-5 years in maritime R&D projects of this complexity.
International regulatory approval through IMO and national maritime authorities adds additional timeline considerations. However, the participation of Korean Register streamlines approval pathways. Early adoption could position HMM vessels and other compatible fleets as sustainability leaders within the shipping industry by 2028-2030.
