DSME announces successful onboard CCS development
Daewoo Shipbuilding & Marine Engineering (DSME) has developed a technology to store carbon dioxide captured in ship engine emissions
The South Korean yard said this was done in partnership with South Korean HVAC supplier Hi Air Korea. The technology collects and stores carbon dioxide using ammonia water absorbent using a DSME patent and Hi Air Korea’s exhaust purification technology.
DSME said the CO2 capture and storage technology was developed to pre-emptively respond to anticipated environmental regulations.
With the wet capture process and mineral carbonation technology that collects and stores a large amount of carbon dioxide using ammonia water, the amount of carbon dioxide absorption can be designed in various ways depending on the size of the device. The company now plans to commercialise the technology. DSME identified carbon capture technology as key to making the industry more competitive to financiers as ESG parameters continue to become important to maritime financing.
The company noted, “As ESG management has become important not only in South Korea but also worldwide, major shipowners in Europe and the United States are demanding high-level eco-friendly technologies.”
DSME vice president and head of ship design Lee Sang-cheol commented, “Based on the successful technical verification of this carbon dioxide capture and storage technology, we will do our best to advance the commercialisation time.”
The company is also developing a class of 23,000-TEU ammonia-powered super-large container ships, VLCCs featuring solid-oxide fuel cells and new-generation propulsion such as a rotor sail system.
Scrubber manufacturer Wärtsilä is also developing an onboard capture carbon system while a project initiated by Japan’s National Maritime Research Institute yielded promising results.
