The Wärtsilä Two-Stroke Future Fuels Conversion Platform introduces ground-breaking fuel injection technology and combustion concept that enables ship owners to move towards a renewable and decarbonised future in a viable and flexible way. Starting from LNG, a widely available and reliable fuel, and transiting later to other fuels such as green methanol, ammonia or blends of fuels, this retrofit solution supports the decarbonisation of existing vessels, increasing their commercial value and lifetime.
Our patented technology platform features a pioneering cryogenic fuel supply system and flexible combustion process, with advantages such as low energy demand and negligible fuel slip. Understanding that off-hire time can be a barrier to fuel conversion projects, the platform design focuses on rapid retrofitting. Further attention is given to design modularity, enabling the switch to a different fuel on the platform with a modest investment and minimal retrofit effort.
Fuel flexibility means that the first step towards adopting the use of future fuels can be taken now knowing that the investment will not become obsolete. The benefits, both economic and environmental, are massive.

Based on current fuel prices, converting two-stroke engines to future fuels brings substantial economic benefits. For typical larger vessels (for example a 10,000–13,000 TEU container ship) consuming 30,000 tons of liquid fuel per year with a 10-year remaining lifetime, the conversion is a sound investment. With less than four years’ payback time the conversion enables CO2 reduction of 21,000 tons annually.
Wärtsilä’s new Two-Stroke Future Fuels Conversion Platform deploys innovative fuel injection technology to significantly reduce integration complexity, capital cost and onboard footprint – bringing the environmental advantages of LNG and future fuels within reach of an even wider range of today’s vessels.
