China's First Newbuild Shipboard Carbon Capture System Successfully Completes Sea Trial
Release time :
2025-09-20
SMDERI-QET has successfully sea-trialled its second Onboard Carbon Capture System (OCCS), this time on a newbuild 82,000 DWT bulk carrier. This achievement demonstrates the rapid advancement and adaptability of our technology across different vessel types.
Key Technical Achievements:
✅ Full-process integration: from absorption, desorption, and compression to liquefaction, storage, and transfer.
✅ High efficiency: achieves a 99% CO₂ liquefaction rate with 99.9% purity.
✅ Optimized for real-world operations: significantly reduced energy consumption and CO₂ dissipation, designed to handle complex open-sea conditions.
Compared to previous container ship retrofit projects, the newbuild system features a more compact design. It successfully overcomes key challenges related to spatial layout and energy management for onboard carbon capture systems on bulk carriers, laying a solid foundation for large-scale promotion and application.
SMDERI-QET has established a complete technological system and industrial capability:
Jan 2024: The world's first full-process Onboard Carbon Capture and Storage System (OCCS) completed sea trials.
Jan 2024: Received the world's first Type Approval Certificate for an Onboard Carbon Capture and Storage System (OCCS) from the China Classification Society.
May 2024: Completed the first full ecological cycle globally, encompassing "onboard carbon capture – liquefaction & storage – ship-to-ship offloading – transfer – carbon utilisation."
Oct 2024: Achieved Carbon Intensity Indicator (CII) deduction.
Jan 2025: Completed the first overseas liquid carbon dioxide (LCO2) offloading operation at the Port of Rotterdam, Netherlands.
Jun 2025: Conducted the world's first ship-to-ship liquified carbon dioxide (LCO₂) transfer operation.
Sep 2025: Took the lead in proposing the international standard Performance Evaluation Method for Onboard Carbon Capture and Storage Systems.
SMDERI-QET will deepen its technological research and product development, strengthen collaboration with shipowners, shipyards, classification societies, and other stakeholders, and promote the adaptation of OCCS technology to all existing ship types. The company aims to diversify real-world application scenarios and accelerate the standardization and regulatory integration of OCCS, actively contributing to the achievement of the shipping industry's net-zero goals.
