WinGD and Alfa Laval to advance ammonia engines

Ammonia is anticipated to become a key fuel in the shipping industry´s efforts to reduce its impact on carbon emissions. To advance the use of zero-carbon fuels, WinGD is at the forefront of developing ammonia-fuelled engines, with the recent achievement of the first-ever Approval in Principle (AiP) from Lloyd's Register for their X-DF-A dual-fuel range powered by ammonia.

In the next step of their ongoing ammonia test campaign, WinGD has partnered with Alfa Laval to provide two customised ammonia fuel supply systems for their Engine Research and Innovation Centre in Winterthur, Switzerland. Alfa Laval will deliver the FSS for the injector test system and FSS for the engine test bench in early 2024. The project is in the framework of WinGD's and Alfa Laval's earlier agreement for cooperation on methanol and ammonia, signed in 2022. This gives both companies the chance to optimise the overall fuel supply and use it for later application onboard.

"Strategic collaboration, like this one with WinGD, represents a definitive pathway towards achieving decarbonisation and fuel transition," says Viktor Friberg, Head of Marine Separation & Fuel Supply Systems, Alfa Laval. "We have expanded our technological expertise to be ready with solutions for ammonia engines in alignment with our ambition. This joint research and development project is an efficient pathway to facilitate the use of one more alternative fuel."

"With each new collaboration we are one step further on the path to running engines with zero carbon emissions," says Sebastian Hensel, R&D Director, WinGD. "Our ammonia testing campaign began in 2021 with extensive research into the combustion characteristics of the fuel. The fuel supply system is an important next step in the technology development, keeping pace with our delivery targets of 2025. We are confident that Alfa Laval's expertise and proven experience in fuel supply applications will be valuable to help us reach our goal."

Alfa Laval's role in the project will draw heavily on its vast technical know-how in fuel supply technology and experience with a wide range of fuels, both conventional and alternative. Alfa Laval FCM, the industry's leading low-flashpoint fuel supply system (LFSS), has a flexible design and fully automated operations to ensure safe and smooth process control.

"Alfa Laval is supporting customers of all types and in all stages of the fuel transition," says Viktor. "We work with a wide range of existing and future marine fuels and adapt our technology to support our customers, regardless of their fuel choice. Drawing on our expertise with LPG, we are ready to handle ammonia in a safe and effective way."

This project will provide a testing environment to help both the companies carry out development activities of the engine and equipment associated with it. Alfa Laval will also investigate and develop a mitigation system to secure safe handling of ammonia.
