WÄRTSILÄ W32 METHANOL ENGINE SCHEDULED FOR 2023

WÄRTSILÄ W32 METHANOL ENGINE SCHEDULED FOR 2023

Thursday, July 22, 2021 

Wärtsilä is developing a new methanol-burning engine based on its proven W32 series. Speaking today at Clean Shipping International's webinar on methanol as a marine fuel, Toni Stojcevski, General Manager, Project Sales & Development, Wärtsilä, said he expects the first deliveries of the new engine to be in late 2023.

The new engine, to be made available as either a main engine or genset for newbuild or retrofit installation, will have a power output between 3000kW and 9000kW in 6l to 16v cylinder configurations. The engine will also be designed to operate on LFO, LBF or HFO as a back-up fuel.

Until now, methanol has not been widely used as a marine fuel. This easily and cheaply produced industrial alcohol is today made predominantly from natural gas, but the use of hydrogen from renewable electricity and recaptured carbon to make green methanol would make it carbon neutral. And with better combustion and easier storage and handling than ammonia, methanol is a key component of decarbonisation in the maritime industry.

A project to convert a Wärtsilä Z40 engine on the ro-pax vessel Stena Germanica to burn methanol began in 2015. The engine now runs mainly on methanol, and the success of the installation #inspired Wärtsilä to investigate this fuel further.
