Sanlorenzo Unveils World-First Green Methanol Superyacht

22 October 2024

Iconic Italian yacht builder Sanlorenzo has unveiled the LIFE MYSTIC* (Methanol for Yachting Sustainable energy Transition applied to Internal Combustion engines) project, created in collaboration with Nanni Industries and Ranieri Tonissi, which will become the first green methanol bi-fuel superyacht by 2027.

The aim of the LIFE MYSTIC project is to test engines and generators for superyachts powered by a combination of diesel and methanol, and significant results are expected in terms of reduced environmental impact:

– reduction in greenhouse gas emissions: 150 t/y CO2eq

– reduction in fossil primary energy consumption: 700 MWh/y

– reduction in air quality contamination: 630 kg/y

Led by Sanlorenzo, LIFE MYSTIC plans to house two high speed 4-stroke MAN diesel engines on board a superyacht – in collaboration with Ranieri Tonissi as a developer partner – along with two 4-stroke diesel generators – made by Nanni Industries – adapted to operate in bi-fuel green methanol – diesel.

The production of bi-fuel adaptation kits involves a very careful engineering process to ensure efficiency and reliability in the combustion of two different types of fuel in a single engine, having to guarantee a safe switch from diesel-only at any time and making these engines the ideal solution for a transitional market.

The boat’s design will be adapted by Sanlorenzo, which will convert two traditional diesel fuel tanks into additional methanol tanks and will integrate the distribution system with the required lines and equipment, completing the conversion to bi-fuel of the entire boat.

The decision to use methanol to power bi-fuel engines in order to reduce environmental impact stems from the fact that this fuel is one of the most promising alternatives for the future of maritime transport.

For all the aspects considered so far, the LIFE MYSTIC project represents an important step forward in the sustainability of the yachting sector, and will bring benefits to the entire marine industry, both in terms of technological development and strengthening the alternative fuel supply chain.

LIFE MYSTIC is part of the ‘Road to 2030’ plan with which Sanlorenzo aims to be a pioneer in environmental sustainability, making it a strategic lever for business growth. The initiative therefore represents a fundamental step in that journey that recently saw the launch of the 50Steel, the first superyacht in the world to use the Reformer Fuel Cell green methanol system to generate electricity, and which aims to launch the first carbon neutral vessel by 2030.
