Process of the CO2 Capture Technology Using Amine

Capturing carbon with amine that binds to carbon

Our OCCS involves capturing and storing carbon emissions from the ship’s exhaust gas. We developed a NaOH-based OCCS (KR AIP) that converts the CO2 absorbed into a type of mineral and stores it, while regenerating and reusing the absorbed liquid during the CO2 absorption process.

Also, we obtained type approval for amine-based OCCS (BV AIP) that captures CO2 by using amine in December 2023.

Our OCCS has been proven to be more cost-effective as it makes better use of space and consumes less energy.

ALS is an energy-saving device that forms a layer of air between the hull and seawater, reducing frictional resistance during navigation and improving fuel efficiency. This system reduces fuel consumption by more than 5% compared to existing LNG carriers, and more than 60 LNG carriers and container ships have applied the system since the first delivery of ALS-equipped vessel in 2019.

We seek to develop various wind-assisted propulsion systems, including the rotor sail system developed for the first time in Korea, in order to improve fuel efficiency of vessels. Wind-assisted propulsion systems can reduce fuel consumption by 6 to 9%, while cutting carbon emissions.

The shaft generator motor system (SGM) is an eco-friendly technology that generates electricity using the rotational force of a ship's propulsion engine shaft. Hanwha Ocean has successfully achieved the industry's first domestic production of this technology. This motor saves fuel and emits less CO2 and sulfur oxide, as well meets regulations for GHG emissions.

We developed a high-manganese steel cargo tank independent type B (MCTIB) with outstanding performance, strength, and wear resistance even at -163°C as a result of a decade of joint R&D with POSCO. MCTIB is a core equipment of green-fueled ships and is currently applied to more than 20 container ships.

Developed by our proprietary technology, our reliquefaction system applies an eco-friendly technology that boosts the operating efficiency of LNG carriers and prevents methane slip as well. Methane is a potent GHG with a global warming potential 25 times that of CO2. Furthermore, we received a BV certification for our reliquefaction system for liquefied CO2 (LCO2) carriers in December 2023. As such, we are taking the lead in developing technologies to cut GHG emissions.

We are in the process of developing a 100% ammonia-capable gas turbine. To make this happen, we intend to secure a propulsion system with zero carbon emissions and zero methane slip in order to respond to the energy transition. Our initiative also includes developing a hybrid electric propulsion system embedded with fuel cells and ESS for power charge and discharge. At our newly built demonstration facility at the Siheung R&D Campus, we conduct simulations of onboard power systems of a marine vessel to test various functions of the hybrid electric propulsion system.
