To be a pioneer in ocean-going environmental protection with enthusiasm and innovation.
First OCCS Delivered for a Newbuild Bulk Carrier
Release time :
2025-09-27
On September 27, the first Onboard Carbon Capture and Storage System (OCCS) for a newbuild vessel in China was officially delivered aboard the 82,000 DWT bulk carrier "SHANDONG XINSHENG" operated by Shandong Shipping Corporation. This breakthrough by SMDERI-QET marks a critical step toward the industrial application of OCCS, providing technical support for achieving the carbon peaking and carbon neutrality goals.
What is the technological core?
A self-contained, efficient, and low-consumption system tailored for ocean-going voyages.
The delivered system is China's first bulk carrier Onboard Carbon Capture and Storage System (OCCS) to encompass the entire process chain: absorption, desorption, compression, liquefaction, storage, and offloading.
The primary challenge in OCCS lies in achieving stable, efficient, and low-energy operation aboard ocean-going vessels, which face spatial constraints and complex operating conditions. SMDERI-QET has successfully overcome key hurdles, including high-efficiency absorbent adsorption technology and zoned parameter control technology. This system maintains high standards of 99% CO₂ liquefaction rate and 99.9% liquid CO₂ purity, while effectively reducing energy consumption and CO₂ dissipation. It also enhances storage tank capacity, making it well-suited for the complex operating environments of ocean-going ships.
The captured CO₂ can be further utilized in producing high-value-added products such as methanol and building materials, forming a "Capture-Utilization-Recycling" closed loop. This approach not only reduces CO₂ emissions effectively but also creates additional economic value for vessel operators.
Where does the iterative upgrade lie?
From retrofitting to newbuild, laying the foundation for scalable application
This delivery is not the debut of China’s OCCS. In 2024, SMDERI-QET successfully delivered a OCCS Retrofit Project for a container ship. The system now applied to a newbuild vessel marks a critical iteration of the technology—transitioning from “post-construction retrofitting” to “source-level design.”
"This represents another breakthrough in our technological evolution, following last year's delivery of the container vessel retrofit project," stated the project leader. He explained that the new system was specifically optimized for the bulk carrier's design, achieving breakthroughs through a more compact and integrated layout, as well as more intelligent and efficient energy management.
This tailored approach solves the challenge of integrating OCCS with vessels, lowers the barrier for pre-installation on newbuilds, and lays a solid practical foundation for widespread adoption.
What is its significance for the industry?
Providing a practical decarbonization pathway and enhancing green industry competitiveness
Faced with increasingly urgent carbon reduction targets in the international shipping industry, OCCS offers a realistic transitional solution. It can effectively reduce carbon emissions without modifying the existing fossil fuel power systems of vessels, demonstrating broad potential for industrialization and extensive adoption.
This project serves as a demonstration initiative for the development of localized equipment and its practical shipboard application, jointly spearheaded by SMDERI and Shandong Marine Group. It represents a concrete implementation of China's "carbon peaking and carbon neutrality" strategy. This is evidenced by a series of key milestones: the strategic agreement signed in March 2023, the world's first full-process OCCS contract inked in December of the same year, the successful trial voyage and delivery of this newbuild, and the recent signing of a letter of intent for new orders. The collaboration has progressed with remarkable efficiency, showcasing China's accelerated advancement in green shipping technology.
Looking ahead, SMDERI-QET will continue to focus on the broader picture of shipping decarbonization. We are committed to establishing a complete technology promotion chain encompassing product certification, development, and shipboard demonstration. Furthermore, we will actively promote international certification and standard-setting for onboard carbon capture products.
