Yeongam, South Korea | December 26, 2025 – Maritime decarbonization leader VINSSEN has reached a historic milestone in the commercialization of zero-emission shipping with the launch of Hydro Zenith, the nation’s first hydrogen fuel cell-powered vessel to be certified under official government safety standards.
The launching ceremony, held at VINSSEN’s headquarters in the Yeongam Daebulsan Complex on December 22, 2025, marks the culmination of a high-stakes joint investment project between the public and private sectors. The vessel is the first in Korea designed and built according to the “Hydrogen Fuel Cell Propulsion Vessel Provisional Standards” established by the Ministry of Maritime Affairs and Fisheries in late 2023.

Technical Prowess: Powering a Quiet Revolution
The Hydro Zenith is a 17.4-meter aluminum-hulled vessel with a gross tonnage of 32 tons. Its innovative hybrid-electric drivetrain eliminates the traditional roar and exhaust of diesel engines, operating with near-silent precision.
Key Propulsion Specifications:
- Primary Power: Two 100kW hydrogen fuel cells.
- Energy Storage: Four 92kWh lithium-ion batteries.
- Performance: A maximum speed of 20 knots, suitable for both passenger and commercial transit.
- Environmental Impact: Zero emissions of nitrogen oxides (NOx), sulfur oxides (SOx), fine dust, and CO2.
Beyond the vessel itself, VINSSEN showcased its self-developed 100kW and 250kW marine fuel cell systems. Notably, the 100kW system has already secured certification from the Korea Maritime Traffic Safety Authority (KOMSA) and the Korea Register of Shipping (KR), making it a “plug-and-play” solution for various ship types, from small leisure craft to larger commercial ferries.
Data-Driven Decarbonization
A standout feature of the Hydro Zenith is the integration of Data Track Recording technology. This system monitors real-time energy usage and operational data, allowing for predictive maintenance and optimized fuel efficiency, a critical factor as shipowners look to manage the higher costs associated with early-stage alternative fuels.
“Hydro Zenith is a tangible example of applying commercialized hydrogen fuel cell technology to an actual ship,” said Lee Chil-hwan, CEO of VINSSEN. “We will continue to improve performance and operability based on data accumulated through actual sea operations to accelerate the spread of eco-friendly marine mobility.”
A Strategic Public-Private Blueprint
The project represents a successful “Regional Innovation Ecosystem,” involving:
- Jeollanam-do & Yeongam-gun: Providing policy support and regional infrastructure.
- Jeonnam Techno Park: Managing technical verification and the demonstration project.
- VINSSEN: Delivering the core engineering, manufacturing, and assembly.
This launch is expected to catalyze a new “Hydrogen Mobility” industry in the region, strengthening the competitiveness of the local shipbuilding cluster while paving the way for hydrogen-powered marine tourism.
