Shanghai-based Ship Research Institute Independently Develops New Generation Marine Carbon Capture System, Secures Key Certification

Recently, the new generation ultra-gravity marine carbon capture system independently developed by the 704th Research Institute of China State Shipbuilding Corporation Limited (CSSC) has undergone rigorous full-process verification by the China Classification Society (CCS). The results show that its core parameters, including regeneration energy consumption, capture rate, and capture liquefaction purity, not only fully meet standards but also lead the industry. The system successfully obtained the Approval in Principle (AiP) certificate, marking a critical step toward practical ship application. It is expected to become a competitive preferred solution in the global ship carbon emission reduction field.

The system integrates high-efficiency mass transfer reaction technology and energy-saving heat transfer design. Through intelligent algorithms, it achieves dynamic control of the system’s operating conditions, demonstrating outstanding comprehensive performance. For example, the carbon capture regeneration energy consumption is <3.0 GJ/ton CO₂, the capture rate is ≥90%, and the CO₂ capture purity is ≥99.9% (with the capability to produce food-grade purity). It is universally compatible with all carbon-based fuels, seamlessly adapting to ships using diesel, liquefied natural gas (LNG), methanol, and other carbon-based fuels, providing practical emission reduction solutions for the entire industry.

Notably, the system also features miniaturization, lightweight design, intelligence, low energy consumption, and modularity, making it highly applicable across various market scenarios.

The successful issuance of the AiP certificate for the 704th Research Institute’s independently developed new generation ultra-gravity marine carbon capture system injects new momentum into the global shipping industry’s pursuit of green, zero-carbon, and sustainable development. It enables ships to continue using traditional fuels while reducing carbon emissions and extending vessel lifespan. Ships equipped with carbon capture technology can meet the carbon emission reduction requirements of the International Maritime Organization (IMO) and various countries while reducing the Carbon Intensity Indicator (CII), enhancing operational cycles and market competitiveness. The captured CO₂ can be reused, such as in the production of chemicals or green fuels, creating additional economic value for ship operators.
