LR approves bulk carrier concept with onboard CCS system

A vessel concept featuring Sinotech Energy’s onboard carbon capture and storage (OCSS) system has received approval in principle from the classification society Lloyd's Register.

China Shipping Development Company (CSDC) has designed a 210,000-dwt bulk carrier concept featuring a combined scrubber and carbon capture technology developed by Chinese marine tech firm Sinotech Energy.

Sinotech Energy’s OCCS system combines carbon dioxide (CO2) captured from a vessel’s exhaust gases with an amine-based solvent. The captured CO2 is then segregated from the solvent by heating, causing a chemical reaction that reverses the CO2 absorption.

Amines are nitrogen-containing organic compounds that help in the absorption and regeneration of CO2.

The segregated CO2 gas will be then liquefied and stored cryogenically in two 2,000-cbm tank arrangements on the vessel using an integrated system. Meanwhile, the solvent will be reused in another process.

The OCSS system has a “potential carbon capture rate of 100%, depending on the ship's route and emission reduction requirements,” LR said.

“Carbon capture technology is among the most reliable methods for achieving decarbonisation in shipping,” Li Dongpeng, Vice General Manager at CSDC said.
