Imagine swapping the fuel in a giant ship's engine from dirty oil to a cleaner alternative like ammonia. This project builds two types of engines: one brand new and one that can be added to existing ships like a plug-in upgrade. It's like upgrading an old car to run on a clean fuel without having to buy a whole new vehicle.
Shipping companies face strict GHG and NOx regulations but cannot replace their entire fleet of ships instantly. They need a way to either build new green ships or upgrade existing ones without losing operational efficiency.
A 10MW four-stroke ammonia engine and a medium-pressure fuel injection retrofit kit for two-stroke engines.
If you are a container vessel operator dealing with strict carbon limits — this project developed a medium-pressure fuel injection platform that can be retrofitted onto any two-stroke engine. This allows you to reduce GHG emissions by at least 80% without replacing your entire fleet.
If you are a shipyard dealing with demand for green newbuilds — this project developed a 10MW four-stroke ammonia engine. This enables the construction of vessels that meet IMO Tier III regulations and reduce CO2 by 2.3 million tons annually for EU port calls.
If you are a port operator dealing with the transition to green fuels — this project investigated ammonia supply infrastructure and safety. This provides the necessary blueprint to support ships that reduce SOx emissions by 15 tons annually.
Based on available project data, specific pricing or cost figures for the engines or retrofits are not provided.
The project is demonstrating full-scale innovations, including a 10MW four-stroke engine and a retrofit platform for two-stroke engines on a container vessel.
Based on available project data, there is no specific information regarding IP rights or licensing agreements.
Yes, the engines are designed to keep NOx emissions below IMO Tier III regulations and ammonia slip below 10ppm.
The project aims for commercial exploitation to enter the fleet within the next ten years.
The consortium is heavily industry-driven, with 7 out of 8 partners (88%) coming from the industrial sector. This high ratio, combined with the involvement of a major alpha customer like MSC and a lead coordinator like Wartsila, indicates a strong focus on commercial viability rather than academic research.
