The maritime industry is required to reduce emissions and improve energy efficiency at the same time as it responds to tightening international environmental regulations and the transition to alternative fuels.

From diesel-powered vessels to low-emission and alternative-fuel vessels powered by LNG, ammonia and hydrogen, Heesung Catalysts supports regulatory compliance, reliable operation and the transition to greener vessels through emissions reduction catalysts and catalyst technologies for clean energy for a wide range of propulsion systems.

As marine fuels change, the bar for environmental performance rises

Vessels must maintain stable performance through long voyages and repeated high-load operation. At the same time, they must effectively reduce emissions such as NOx, HC and methane, which vary with fuel and engine characteristics.

Recently, as the use of low-carbon and carbon-free fuels such as LNG, ammonia and hydrogen expands beyond conventional diesel, marine catalyst technology is required to take on new roles.

Marine SCR Catalysts

Applied to reduce NOx from marine engines and to meet tightening emissions regulations. Honeycomb or corrugated structures are used so that stable reduction performance is maintained through long voyages and across varying exhaust gas conditions.

Methane Oxidation Catalysts (MOC)

On LNG-fueled vessels, greenhouse gas management must address methane slip, the release of unburned methane from the engine. MOC oxidizes this unburned methane to reduce emissions and improve the environmental performance of LNG vessels.

AOC Catalysts

Ammonia remaining downstream of an SCR system requires additional emissions management. AOC catalysts reduce residual ammonia, supporting post-SCR emissions control and stable system operation.

Ammonia Cracking Catalysts

Using ammonia as a marine fuel or hydrogen carrier requires technology that converts it back into hydrogen when needed. Heesung Catalysts’ ammonia cracking catalysts decompose ammonia into hydrogen and nitrogen, expanding the potential for hydrogen-based propulsion systems and low-emission vessel technologies.

Fuel Cell Electrocatalysts

In fuel cell-powered vessels, the efficiency and durability of electrode reactions have a major impact on system performance. Heesung Catalysts’ fuel cell electrocatalysts accelerate the reaction between hydrogen and oxygen, contributing to stable power output and efficient energy use.
