• Dual-fuel engine manufacturers are increasingly developing multi-fuel platforms capable of operating with LNG, methanol, ammonia, hydrogen, and other lower-carbon fuels, allowing shipowners and power producers to future-proof long-life engine assets while maintaining fuel flexibility.
• For instance, in February 2025, MITSUI E&S began full-scale testing of the world’s first commercial two-stroke dual-fuel ammonia engine, the MAN B&W 7S60ME-LGIA, which is planned for installation on a 200,000-dwt bulk carrier, demonstrating the industry’s shift toward ammonia-capable dual-fuel propulsion.
• Engine manufacturers are increasingly integrating advanced combustion controls and fuel-management systems to improve efficiency, reduce emissions, and enable reliable switching between conventional and alternative fuels during vessel or power-plant operations.
• Marine operators are accelerating adoption of alternative-fuel engines as LNG, methanol, ammonia, and hydrogen-ready technologies become increasingly available for newbuild vessels and engine-conversion projects.
• For instance, in November 2024, Reuters reported that 522 dual-fuel container ships were on order as of October 2024, including 303 LNG-fuelled and 216 methanol-fuelled vessels, highlighting the growing adoption of fuel-flexible engines as shipping companies prepare for the transition toward lower-carbon fuels.
• As shipping and power-generation industries increasingly prioritize fuel flexibility, emissions reduction, and long-term asset adaptability, multi-fuel dual-fuel platforms are expected to become an increasingly important pathway for the transition toward cleaner energy systems.

What are the Key Drivers of the Dual Fuel Engine Market?

• The tightening of global emissions regulations and decarbonization targets is significantly increasing demand for dual-fuel engines that can operate on cleaner fuels while retaining conventional-fuel capability for operational reliability.
• For instance, in April 2025, the International Maritime Organization (IMO) approved draft Net-Zero Framework regulations introducing mandatory greenhouse-gas fuel standards and global emissions pricing for large ocean-going ships, strengthening the regulatory push toward cleaner fuels and accelerating demand for dual-fuel engine technologies.
• Shipowners, utilities, and industrial operators are integrating dual-fuel systems to lower emissions, improve fuel flexibility, reduce exposure to fuel-price volatility, and maintain reliable operations as alternative-fuel availability expands.
• For instance, in June 2024, Wärtsilä reported that LNG produces 20–30% less CO₂ than heavy fuel oil when burned and that methane slip from its dual-fuel engines had been reduced by around 90% since 1993, reaching below 2 grams per kWh, supporting the adoption of LNG-capable dual-fuel engines for lower-emission marine operations
• With maritime and energy industries increasingly transitioning toward lower-carbon fuels while requiring dependable power and propulsion, dual-fuel engines will remain an important technology for balancing decarbonization objectives with operational flexibility.

Which Factors are Challenging the Growth of the Dual Fuel Engine Market?

• The environmental performance of LNG-based dual-fuel engines remains challenged by methane slip, in which unburned methane escapes through the exhaust and can reduce the overall greenhouse-gas benefits of switching from conventional marine fuels.
• For instance, in March 2024, MAN Energy Solutions announced that ammonia-fuelled ship engines would require further trial phases, infrastructure development, and stringent safety measures because ammonia is toxic, while green ammonia production was not expected to scale significantly before 2030, highlighting the high infrastructure and technology requirements associated with next-generation dual-fuel engines
• This challenge is particularly significant for low-pressure four-stroke engines operating at lower loads, where methane emissions can increase substantially and require advanced combustion controls and after-treatment technologies.
• The development of methane-reduction technologies, onboard monitoring systems, and alternative fuels such as ammonia and hydrogen increases technology complexity and can raise engine development, installation, fuel-storage, and maintenance costs.
• For instance, in March 2024, Reuters reported that the shipping industry was facing uncertainty over alternative-fuel investments because different fuel options, infrastructure requirements, and emerging emissions regulations were complicating decisions on future vessel and engine technologies
• These technical, economic, and infrastructure challenges can slow adoption, particularly where LNG bunkering or alternative-fuel supply networks remain limited and operators face uncertainty regarding the long-term availability and cost of cleaner fuels
