First Full-Scale Tests of 175DF Methanol Engine Successfully Started

Everllence has announced the successful completion of full-scale testing for its 175DF-M dual-fuel methanol engine at their Test and Research Center in Frederikshavn, Denmark. The 12-cylinder engine, originally optimized in 2025, has demonstrated its capability to operate efficiently in both diesel and methanol modes. The 175DF-M engine is designed to achieve its peak efficiency when over 95% of its fuel is methanol, particularly in a variable speed configuration.

This is made possible through the use of a low-pressure port-fuel-injection system, which simplifies fuel supply arrangements, reduces system complexity, and lowers installation costs. The engine's modular design also allows for straightforward retrofitting, providing shipowners with the flexibility to transition towards carbon-neutral operations as needed.

Everllence has already secured its first commercial orders for the high-speed engine, with deliveries of 12V and 16V175DF-M variable-speed gensets to two different superyacht customers scheduled for mid-2027. The company sees the 175DF-M as a crucial component in its efforts to assist the shipping industry in its transition to lower-carbon operations.

Florian Keiler, Sales & Business Development Manager at Everllence, expressed optimism about the engine's performance and its potential to support a wide range of maritime applications, including superyachts, tugs, offshore platforms, governmental vessels, and passenger ships. The company aims to collaborate with customers to develop practical and efficient solutions for maritime decarbonization.
