NH₃ Gas Turbine Propulsion System

We are developing our own proprietary ammonia combustors after passing phase-by-phase combustion testing.

Ammonia Gas Turbine

Achievement

While ammonia's narrow ignition range and slow combustion speed make flame control challenging, we address these issues through proprietary 100% ammonia combustion and dual-fuel combustion technologies.
Although nitrogen oxides(NOx) from ammonia combustion are major air pollutants, our proprietary eco-friendly ammonia turbine meets IMO's strict exhaust gas regulations without additional SCR equipment.

We have obtained AIP(Approval in Principle) from the American Bureau of Shipping(ABS) for applying ammonia turbines to LNG carriers.

Application

The ammonia ship propulsion system fully complies with the IMO's enhanced emission regulations.
Furthermore, it serves as a definitive alternative for fuel conversion, applicable to various vessels, including gas carriers and container ships.
We are the optimal partner for both new ship construction and vessel retrofitting.

Marine :
LNG carriers, LPG carriers, ammonia carriers(VLAC), container ships, bulk carriers, tankers, etc. * Capability to convert existing vessel propulsion systems to eco-friendly(zero-carbon) propulsion systems

Future expansion into onshore power generation applications

Advanced Combined Cycle System(sCO₂)

The supercritical carbon dioxide(sCO₂) power system increases efficiency while reducing installation space. Operable in freshwater-scarce environments, it can reduce carbon emissions in land-based power plants, marine plants, and ship propulsion systems.

Achievement

One hundred thousand ships emit more than 1 billion tons of carbon dioxide annually.
Hanwha is building a 'Zero-Carbon Ship Value Chain' encompassing propulsion system manufacturing, shipbuilding, and transportation to achieve maritime decarbonization through zero-carbon fuel technology.

HRS with Steam or sCO₂, Ammonia Fueled Gas Turbine

Application

Carbon emission regulations by the International Maritime Organization(IMO) and EU are becoming stricter, with countries implementing detailed strategies to achieve carbon neutrality in international shipping by 2050.
Consequently, demand for zero-carbon propulsion systems will surge dramatically. The sCO₂ power system leads marine zero-carbon power generation by converting waste energy from ammonia(NH₃) gas turbines into electricity and supplying additional power to ship propulsion systems.

Furthermore, Small Modular Reactors(SMR), developed as a fourth-generation nuclear power by many global companies, will play a crucial role in future zero-carbon electric-powered large container ships. Our sCO₂ power system applies to SMRs, serving as a power conversion system that transforms heat into electricity, staying ahead of global eco-friendly trends.
