Sanlorenzo, in collaboration with MAN, has announced the development of a yacht equipped with a bi-fuel green methanol propulsion system, designed to reduce navigation emissions by up to 70%. The project, unveiled at the Blue Innovation Dock at Boot Düsseldorf, will debut on Sanlorenzo’s 50 X-Space model, planned for launch in 2027.

The bi-fuel propulsion system forms part of the LIFE MYSTIC project, co-financed by the European Union under the LIFE program. The initiative, which began in June 2024 and spans 54 months, represents a €4.8 million investment, 60% of which is funded by EU grants. The project involves the installation of MAN diesel engines and Nanni Industries generators adapted to run on a combination of green methanol and diesel. Expected outcomes include significant reductions in greenhouse gas emissions, fossil fuel consumption, and air pollutants.



Methanol was selected for its potential as an alternative maritime fuel. It is liquid at ambient temperature, biodegradable, and compatible with existing infrastructure with minimal modifications. When derived from renewable sources, green methanol achieves net-zero emissions. This fuel is already available in over 100 ports worldwide, with its use growing in Northern Europe, where green corridors support methanol-fueled vessels.

Sanlorenzo’s strategy anticipates global and European regulatory targets for emission reductions. The 50 X-Space model aims to surpass the International Maritime Organization’s 2040 target of a 70% emission reduction and the EU’s 2030 Fit for 55 agenda goal of 55%.

The project aligns with Sanlorenzo’s broader "Road to 2030" strategy, focusing on sustainability and innovation. In 2024, the company introduced the 50Steel, the first yacht with a green methanol fuel cell system for onboard energy, and the BGH-HSV, a hydrogen-powered chase boat capable of achieving zero emissions.

Through initiatives like LIFE MYSTIC, Sanlorenzo is contributing to the development of alternative fuel technologies and infrastructure. 

Sanlorenzo was founded in 1958 in Viareggio by yacht builder Gionvanni Jannetti. In 2005, Massimo Perrotti became the majority shareholder in the shipyard. Sanlorenzo builds yachts ranging from 28.60 to 73 meters in length.
