From Concept to Commercial Reality
The maritime sector is swiftly embracing ammonia as a viable zero carbon fuel. With three ammonia capable vessels already sailing and more than forty on order, Everllence has accelerated progress by unveiling its ME LGIA dual fuel two stroke engine rated up to fifteen megawatts. Built on the proven ME C platform, the engine can alternate between conventional fuel and renewable ammonia, giving owners operational flexibility while infrastructure develops.
Non-Obvious Advantage: Compatibility with Slow Speed Operations
A less discussed benefit of ammonia propulsion is its natural fit with the low speed two stroke engines that dominate bulk carriers and tankers. Ammonia burns more slowly than diesel, and the extended combustion duration inside large cylinder volumes actually improves efficiency at typical deep sea revolutions per minute. This characteristic means that early adopters can secure performance parity without dramatically altering voyage schedules or hull designs.
Engineering for Safety and Reliability
Everllence devoted more than one hundred fifty thousand engineering hours and eight hundred laboratory tests to address ammonia toxicity. Double walled piping, continuous ventilation, nitrogen purging and an ammonia catch system containing water column scrubbing collectively create multiple containment layers. Integrated sensors feed data to shore based analysts who provide real time guidance, turning each voyage into a rolling research program that refines operating parameters.
Digital Connectivity and Modular Upgrades
The engine communicates securely with Everllence cloud services, enabling predictive maintenance and firmware updates while the vessel remains at sea. Because the architecture remains modular, shipowners can retrofit existing ME C engines by replacing fuel systems rather than entire power plants. This capital efficient pathway could accelerate fleet wide adoption, particularly for owners balancing decarbonisation goals with financial prudence.
Conclusion
By combining fuel flexibility, advanced safety measures and data driven support, Everllence has transformed ammonia propulsion from laboratory concept into a practical tool for zero carbon deep sea trade. The launch signals strong momentum toward meeting International Maritime Organization climate targets.
