Korea Demonstrates Marine Ammonia Engine Technology, Cutting CO2 Emissions by 50%

In Korea, researchers at Korea Institute of Machinery and Materials (KIMM) successfully demonstrated an MW-class marine engine combustion technology using ammonia that reduces carbon dioxide emissions by 50%.

The joint research team, led by Cheol-Woong Park of KIMM, injected ammonia at high pressure into the combustion chamber, achieving stable, high-power combustion with significant thermal efficiency. Ammonia, despite being a promising carbon-neutral fuel, poses challenges due to its corrosiveness and toxicity. The research team overcame these by modifying the O-ring material in the supply system, preventing corrosion and external leakage, and optimizing the fuel injection timing and combustion speed.

Park said, “The technology can be applied to a ship’s engines, it can also expand its application to various power sources that must reduce greenhouse emissions such as automobiles and generators.”
