World’s First Dual-Fuel X-DF Engine with VCR Technology by Hanwha Engine

Hanwha Engine, a division of Hanwha Group, has unveiled the world’s first dual-fuel X-DF engine featuring variable compression ratio (VCR) technology, designed for liquefied natural gas (LNG) carriers. The 5X72DF-2.2 engine, which can operate on both LNG and diesel, incorporates WinGD’s low-emission technology, marking a significant advancement in the shipbuilding industry’s efforts toward decarbonization.

This innovative engine enhances fuel efficiency and reduces carbon emissions by dynamically adjusting its compression ratio to suit operational conditions. Hanwha Engine reports that the VCR technology can cut methane slip by 30 % to 50 %, addressing a key challenge in reducing greenhouse gas emissions in global shipping.

The introduction of this technology has generated significant market interest, with Hanwha Engine securing orders for 70 VCR-equipped engines, valued at $500 million. According to Hanwha Engine CEO Moon Ghee Ryu, this achievement is not only a technical milestone but also a pivotal step in accelerating the shipbuilding industry’s transition to environmental sustainability. The company aims to continue leading the sector by advancing clean energy solutions to protect the marine environment.

Additionally, Hanwha Group has announced a $5 billion investment in the Hanwha Philly Shipyard in Pennsylvania, aligning with South Korea’s broader $150 billion commitment to the U.S. shipbuilding industry. This investment coincides with the christening of a new training vessel for the U.S. Maritime Administration, highlighting Hanwha’s strategic focus on sustainable maritime innovation.
