Strength in numbers. That is why Nanni and ScandiNAOS AB have collaborated to develop a methanol-powered dual-fuel version of Nanni\u2019s engines, based on John Deere technology.<\/strong><\/p>\n

This collaboration has proven successful, with tests indicating that the engine supports the sector\u2019s energy transition and has enabled Nanni to develop its first high-speed generator set with methanol dual-fuel technology<\/b>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A collaboration born of a need for sustainable innovation\u00a0<\/h3>

In response to the International Maritime Organisation (IMO) call for a significant reduction in air emissions, Nanni embarked on developing advanced dual-fuel technology. Through the Life Mystic project, Nanni has developed an innovative dual-fuel technology enabling engines to run on both diesel and methanol. A solution designed to operate with a fuel blend consisting of approximately 30% diesel and 70% methanol on an energy basis, in order to reduce diesel consumption and harmful emissions. This \u201cdual-fuel\u201d approach represents a major step forward in the maritime sector\u2019s energy transition, offering a more sustainable alternative without compromising engine performance and reliability.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

ScandiNAOS\u2019s expertise in support of Nanni solutions<\/h3>

ScandiNAOS AB was commissioned by Nanni to develop a dual-fuel version of the 6-litre John Deere-based engine for use as a generator set. At the heart of this development is a dual-fuel injection kit that enables these Nanni<\/a><\/span><\/strong> engines to switch between methanol and diesel. When the methanol tank is empty, the engine automatically reverts to diesel without interrupting operation.<\/p>

The conversion kit developed by ScandiNAOS AB<\/a><\/span><\/strong> includes a methanol control system and hardware modifications that enable methanol injection into the fuel system.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Using methanol marks a major step towards cleaner boating, reducing CO\u2082 emissions, fine particulate matter, and certain air pollutants traditionally associated with conventional marine fuels.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Successful test for the Nanni dual-fuel engine<\/h3>

The engine, converted to a methanol dual-fuel configuration, underwent testing. The test was conducted in accordance with IACS<\/a><\/span><\/strong> (International Association of Classification Societies) standards regarding progressive loading of engines and generator sets, in the presence of a representative from RINA<\/a><\/strong><\/span> (Registro Italiano Navale).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The tests delivered positive results<\/h3>

The transition between single-fuel and dual-fuel modes is smooth and seamless during operation. The proportion of energy derived from methanol ranges from 50% to 75%, which significantly reduces emissions while maintaining full power output in both diesel and dual-fuel modes. After conversion to methanol, the engine shows a dramatic reduction in key pollutants, with CO (carbon monoxide) and HC (hydrocarbon) emissions reduced by 95-99% and NOx (nitrogen oxides) emissions reduced by 65% across most load points. Particulate matter is also consistently lower, confirming significantly cleaner combustion.<\/p>

These conclusive results confirm the strong potential of methanol dual-fuel technology. As the first Nanni high-speed dual-fuel engine<\/strong>, this innovation paves the way for a new generation of marine engines.<\/p>

Beyond this technical advancement, the collaboration between Nanni and ScandiNAOS AB reflects a shared vision in which innovation goes hand in hand with transition.<\/p>
