Hanwha Engine, a division of the Hanwha Group, has announced the production of what it claims to be the world's first dual-fuel X-DF engine with variable compression ratio (VCR) technology for liquefied natural gas (LNG) carriers.
The 5X72DF-2.2 engine is capable of operating on both LNG and diesel fuel and utilises WinGD's low-emission engine technology. It marks a step towards decarbonisation in the shipbuilding industry.
This innovation is expected to enhance fuel efficiency and reduce carbon emissions by dynamically adjusting the engine's compression ratio based on current operational conditions.
According to Hanwha Engine, the VCR technology has the potential to decrease methane slip by 30% to 50%, a critical concern for the global shipping industry as it strives to cut greenhouse gas emissions.
Hanwha Engine's introduction of this technology has attracted considerable interest, with the company securing orders for 70 units of the VCR-applied engine, valued at $500m.
Hanwha Engine CEO Moon Ghee Ryu said: “The world’s first production of VCR-applied engines for LNG carriers is not merely a technical achievement but a milestone accelerating the shipbuilding industry’s transition toward environmental sustainability.
“Moving forward, Hanwha Engine will continue to lead the industry by leveraging clean energy technologies to shape the future and make tangible contributions to marine environmental protection.”
Recently, Hanwha Group announced a $5bn investment in Hanwha Philly Shipyard in Pennsylvania.
This move aligns with South Korea's commitment to invest $150bn in the US shipbuilding industry and coincides with the christening of a new training ship for the US Maritime Administration.
