Swiss marine power company WinGD has achieved a milestone by completing Type Approval Testing and Factory Acceptance Testing for its ammonia-fueled two-stroke engine, the X52DF-A-1.0. Conducted in January 2026 in South Korea, these tests mark a significant step towards eco-friendly marine propulsion, with lower emissions compared to traditional diesel engines.
Wärtsilä has introduced its advanced 4-stroke ammonia engine, achieving a 90% reduction in greenhouse gas emissions compared to diesel engines. This engine, part of the Wärtsilä 25 platform, utilizes a low-pressure Otto cycle design, ensuring safety and efficiency. Initial deliveries are expected by 2026, supporting the shipping industry’s decarbonization efforts.
MAN Energy Solutions achieved a significant milestone with its ME-LGIA engine running on Liquid Gas Injection Ammonia at 100% load during testing. The cautious approach since November 2024 paid off, marking a crucial step in maritime energy transition. Positive emission and performance characteristics were confirmed, with focus now on optimizing performance and emissions for future development.
