HD Hyundai Heavy Industries (HHI) has achieved a breakthrough in maritime decarbonization by developing the world’s first ammonia-powered vessels, marking a turning point in the adoption of clean energy in international shipping.
Christening of ammonia-powered vessels
Recently, HHI held a christening ceremony for two medium-sized gas carriers at its Ulsan shipyard, marking a significant advancement in the use of alternative fuels in maritime transport.
The vessels, named Antwerpen and Arlon, have a capacity of 46,000 m3 and have been designed to operate with dual-fuel engines. These ships are part of an order placed by Exmar LPG France, a subsidiary of the Belgian shipping company Exmar, with deliveries scheduled for May and July of this year.
In technical terms, the vessels measure 190 meters in length, 30.4 meters in beam, and 18.8 meters in height. They are equipped with three cargo tanks developed using HHI’s proprietary technology, allowing for the safe transport of ammonia and liquefied petroleum gas.
Furthermore, they incorporate advanced systems such as shaft generators for power production and SCR technology that reduces nitrogen oxide emissions. These solutions enhance their environmental performance compared to conventional vessels.
Additionally, they include specific safety systems for ammonia handling, such as real-time leak detectors and gas recovery units.
Ammonia gains ground as a fuel
The use of ammonia as a marine fuel is positioning itself as a viable alternative within the energy transition. This carbon-free compound can be stored under relatively moderate conditions, facilitating its implementation compared to other options such as hydrogen.
Moreover, its energy density in a liquid state exceeds that of hydrogen in volumetric terms, making it an efficient solution for long-distance transport.
According to projections from the International Energy Agency, ammonia could represent 8% of maritime fuel consumption by 2030 and reach up to 46% by 2050.
In this context, HHI seeks to consolidate its leadership in the development of eco-friendly vessels. The company has already secured orders for several additional ammonia-powered units and continues to expand its portfolio of sustainable solutions in the shipbuilding industry.
