Wärtsilä Launches Four New Methanol Engines Paving The Way For Sustainable Shipping

With the launch of the four newest methanol engines, industry leader Wärtsilä is well-positioned to accelerate the marine sector’s shift to sustainable fuels. This action sets a new industry standard by providing the broadest range of methanol engines.

The company is expanding its range of engines explicitly made to run on methanol fuel by adding the Wärtsilä 20, Wärtsilä 31, Wärtsilä 46TS, and Wärtsilä 46F to complement the previously released Wärtsilä 32 engine.

One of the most promising alternative fuels for the shipping industry’s goal of net-zero carbon emissions by 2050 is methanol. ‘Green’ methanol is desirable because it is produced with carbon capture advanced technology and renewable energy sources, making it a carbon-neutral and sustainable choice.

Across its entire diesel engine collection, including both new and old engines, Wärtsilä is actively working to develop methanol retrofit competence. Upgrades for Wärtsilä 31, Wärtsilä 46F, Wärtsilä 32, Wärtsilä 46TS, and Wärtsilä ZA40S engines are either in the works or currently available.

In addition, the Wärtsilä 20 engine can now be configured to burn methanol. This development guarantees that methanol-powered engines will be widely used in the marine industry on various vessel types.

The head of Wärtsilä’s Marine Power division, Roger Holm, highlights the importance of decarbonisation in the company’s long-term plan. Creating engines that can run on environmentally friendly fuels is essential to this objective. Holm points out Wärtsilä’s creative strategy for assisting the marine sector’s shift to sustainable operations.

Wärtsilä Marine Power’s Power Supply Vice President, Stefan Nysjö, emphasises the company’s significant investments in creating fuel-flexible products and technologies.

Acknowledging the importance of offering ship owners the most important degree of flexibility and choices possible in their pursuit of net-zero emissions, Wärtsilä projects to furnish operational flexibility.

Being one of the few manufacturers of marine engines with decades of methanol engine experience, Wärtsilä began experimenting with this technology in 2015 when it changed the first four engines aboard the ferry Stena Germanica.

One of the first commercially available solutions for using methanol as a maritime fuel was introduced by Wärtsilä with the launch of the MethanolPac supply system and the Methanol Wärtsilä 32 engine the previous year. Several classification societies have awarded the Wärtsilä 32 engine-type approval certification.

The four recently unveiled methanol engines are expected to be delivered at different times starting in 2025.
