Daewoo Shipbuilding & Marine Engineering (CEO Park Doo-seon) announced on the 6th that it has successfully completed performance verification by installing an onboard CO2 capture system (OCCS) equipment on an actual LNG carrier.
With the success of the actual verification of the OCCS equipment, it has established itself as a leader in the field of eco-friendly shipbuilding through carbon neutrality. Daewoo Shipbuilding & Marine Engineering has been jointly developing OCCS with Hi Air Korea, a domestic shipbuilding equipment company, since 2020.
The OCCS technology, verified by Daewoo Shipbuilding & Marine Engineering, absorbs some of the carbon dioxide in the exhaust gas generated during ship operation through an aqueous sodium hydroxide (NaOH) solution, which is an absorbent, and converts it into a mineral, and the absorbent is regenerated and reused in the carbon dioxide absorption process. The carbon dioxide captured in this process can be stored in the form of minerals and unloaded on land after entering the port, or discharged to the ocean according to the results of the marine environmental impact assessment currently being carried out.
Daewoo Shipbuilding & Marine Engineering (DSME) has completed the continuous process of absorption, regeneration and mineralization of carbon dioxide contained in these exhaust gases by mounting this equipment on an actual ship.
Daewoo Shipbuilding & Marine Engineering's technology consumes very little energy compared to other carbon dioxide capture technologies, and the amount of additional carbon dioxide generated by equipment operation is relatively small. In particular, the size of the facility is relatively small, so it is expected to receive a lot of attention from the market. Daewoo Shipbuilding & Marine Engineering holds 42 domestic and foreign patents related to the technology.
The International Maritime Organization (IMO) continues to strengthen its policies to regulate greenhouse gas emissions such as carbon dioxide according to the Energy Efficiency Rating Index (EEDI/EEXI) and Carbon Intensity (CII) standards. Vessels that do not satisfy the tightening regulations will be restricted in their operation, and their competitiveness in the shipping market will decrease. The shipbuilding and shipping industry is actively developing technologies to achieve carbon neutrality to prevent global warming.
Daewoo Shipbuilding & Marine Engineering (DSME) is developing an optimal 'carbon-neutral' ship by closely predicting the tightening environmental regulations and the market demand of the shipping industry. OCCS technology is drawing attention as one of the eco-friendly technologies that can preemptively respond to global environmental regulations. With the successful verification of the OCCS technology, it is expected to become an innovative greenhouse gas reduction technology that can prepare for the 2050 carbon-neutral era.
“DSME has established itself as a leader in eco-friendly technology through real ship verification,” said Jun-ryong Seo, managing director of Daewoo Shipbuilding & Marine Engineering’s technology division. We will also meet their needs,” he said.
Daewoo Shipbuilding & Marine Engineering (DSME) is conducting a Joint Development Project with Gaslog, a Greek shipping company, and ABS in the US to apply OCCS to ships currently under construction. end.
