WinGD and CMB.TECH co-develop large ammonia-fuelled engines

Swiss marine power company WinGD and Belgian shipping and cleantech group CMB.TECH have signed an agreement on the development of ammonia-fuelled two-stroke engines, aiming to install the ammonia dual-fuel X72DF engine on a series of 10 x 210,000 DWT bulk carriers to be built at a Chinese shipyard in 2025 and 2026.

Under the joint project, CMB.TECH will support WinGD in establishing its ammonia-fuelled engine concept for a large bore engine. The two companies believe that ammonia can play a very significant role in the decarbonisation of the maritime industry. The series of large bulk carriers powered by WinGD’s ammonia engines will be the first of its kind and proof that large sea-going vessels can be powered by zero-carbon fuels.

“We believe that ammonia is the most promising zero-carbon fuel for deep sea vessels” said CMB CEO Alexander Saverys. “Our intention is to have dual-fuel ammonia-diesel engines on our dry bulk vessels, container vessels and chemical tankers. Collaborating with WinGD on the development of the first ammonia-fuelled two-stroke engines for our fleet is a pioneering partnership on the road to zero emissions in shipping.”

WinGD CEO Klaus Heim added that the project is a significant step in accelerating the company’s ammonia technology roadmap for a zero-carbon future and that CMB.TECH’s input into the engine development will be invaluable given their alternative fuel expertise and their ship operator’s perspective on how an engine concept is implemented and ultimately operated.

The newest engines in WinGD’s X-DF portfolio will add ammonia capability to the proven technology of WinGD’s X engines. They will be based on the X92B engine, whose market-leading fuel efficiency makes it an ideal starting point for developing large bore ammonia-fuelled engines.

The development project with CMB.TECH is one of several projects WinGD is carrying out with shipowners and engine builders to ensure that dual-fuel ammonia two-stroke engines will be available as the global fleet prepares to adopt green fuels to meet long-term decarbonisation targets.
