Japanese maritime transportation company Kawasaki Kisen Kaisha, Ltd. (“K” Line) on Monday (31 August) said it will deploy a small-scale, marine-use demonstration plant for CO2 capture onboard a vessel and conduct research and development on a compact facility design in collaboration with project partners Mitsubishi Shipbuilding Co Ltd and non-profit organization Nippon Kaiji Kyokai (ClassNK).

The project is supported by the Maritime Bureau of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) as part of its programs to support research and development for advancing marine resources technologies, it added.

With the support of MLIT, “K” Line said it will collaborate with Mitsubishi Shipbuilding and ClassNK to install a small-scale CO2 capture demonstration plant onboard its vessel, conduct test operations of the plant, and measure its performance.

The marine-use CO2 capture demonstration plant will be based on an onshore plant and designed to capture a portion of a vessel’s gas emissions, it explained. 

This project will not only verify the efficacy of capturing and storing CO2 from a vessel’s gas emissions, but also the operability and safety of CO2 capture facilities at sea.

These demonstration tests are aimed at promoting the development of more compact equipment required by marine environments along with the development of system requirements necessary for stable continuous operation at sea.

The following is the timeline for the project:

  • The two-year project will begin in August 2020 with the launch of a HAZID (hazard identification) evaluation of the demonstration plant and deployment on vessels, with verification from ClassNK.
  • Mitsubishi Shipbuilding will begin development and construction of a small-scale CO2 capture demonstration plant and evaluation of system safety. 
  • In the mid  2021, Mitsubishi Shipbuilding will begin to test operation of the demonstration plant at its factory, followed by deployment of the plant on “K” Line’s Corona Utility, a thermal coal carrier operated for Tohoku Electric Power Co., Inc. 
  • By the end of fiscal 2021, the project partners will start operating the demonstration plant on-board the vessel and measuring the system’s performance under marine conditions, with the aim of jointly developing a new marine system for vessels.

As the world’s first marine demonstration test, the project will provide invaluable insights into facilities design and technologies for capturing CO2 emissions and achieving zero emissions onboard vessels. 

Additionally, the captured CO2 is expected to be recycled as a new CO2 source for Enhanced Oil Recovery (EOR) processes or as raw material in synthetic fuel through methanation. 

In this way, the project will significantly contribute to the long-term reduction of greenhouse gas emissions.

StormGeo and OceanScore link emissions data, compliance workflows

Weather intelligence and decision support solutions provider StormGeo and Hamburg-based technology platform OceanScore on Wednesday (3 June) said they have deepened their ongoing cooperation through the signing of a collaboration agreement during Posidonia 2026 in Athens on 2 June.

The cooperation combines StormGeo’s expertise in operational vessel and emissions data with OceanScore’s expertise in emissions compliance workflows across EU ETS, FuelEU Maritime and upcoming UK ETS requirements.

Together, the companies aim to help shipping companies seamlessly navigate increasing regulatory complexity more efficiently — from emissions reporting and data validation to compliance exposure management, pooling and financial settlement.

As emissions regulation becomes an increasingly important part of commercial shipping operations, the need for reliable operational data and streamlined compliance processes continues to grow. The cooperation between StormGeo and OceanScore is designed to support shipping companies with more connected, transparent and actionable processes across operational and commercial teams.

“From the outside, companies like StormGeo and OceanScore may sometimes be perceived as competitors because both operate around emissions and compliance workflows,” said Albrecht Grell, Managing Director at OceanScore. 

“But in reality, the industry increasingly needs both perspectives working together: trusted operational emissions data on one side and commercial compliance execution on the other. Our cooperation reflects that shipping companies are no longer looking for isolated solutions — they need connected processes, automated across different systems and reliable decision-making throughout the full compliance chain.”

By connecting validated operational emissions data with commercial compliance management, the cooperation supports workflows across:

  • emissions reporting and validation 
  • compliance management across EU ETS, FuelEU Maritime and upcoming UK ETS requirements
  • exposure visibility and cost transparency
  • pooling, settlement and financial processes 

The cooperation also aims to improve commercial transparency and coordination across operational and commercial stakeholders.

“StormGeo plays a central role in helping shipping companies turn operational vessel and emissions data into trusted, decision-ready insights,” said Espen Martinsen, Chief Commercial Officer at StormGeo. 

“As emissions regulations become more complex, this data is essential for transparent and efficient compliance management. By working with OceanScore, we can help customers connect StormGeo’s validated operational data with commercial compliance processes, creating a more integrated and practical approach to emissions management.”

The signing ceremony took place at the StormGeo booth during Posidonia 2026 in Athens and was attended by representatives from both companies.

Both companies expect the cooperation to continue evolving alongside upcoming regulatory developments, including FuelEU Maritime, EU ETS, the upcoming UK ETS and future emissions-related frameworks affecting global shipping.

Seaspan and Hapag-Lloyd complete first of five methanol vessel retrofit

Seaspan Corporation (Seaspan) and Hapag-Lloyd on Wednesday (3 June) announced the successful completion of the first of the five vessel conversions under their methanol retrofit programme with the delivery of Seaspan Yangtze.

From the early SAVER (Seaspan Action for Vessel Energy Reduction) programme to today’s CleanBlue initiative, Seaspan has committed over USD 230 USD million across 86 vessels, executing more than 550 efficiency and retrofit projects.

Following Seaspan Yangtze, the remaining vessels planned for retrofit under the programme are Seaspan Amazon, Seaspan Ganges, Seaspan Thames, and Seaspan Zambezi. Each retrofit is expected to reduce well-to-wake CO₂e emissions by approximately 30,000 to 50,000 metric tonnes per vessel annually when operating on low-carbon methanol, while also extending vessel lifespan and enhancing fuel flexibility.

“Decarbonisation is not just about building the fleet of tomorrow, it is also about unlocking the full potential of the fleet we have today. Retrofitting and upgrades on existing fleets play a practical, immediate, and economical role in accelerating shipping’s decarbonization journey,” said Bing Chen, Chairman, President and CEO of Seaspan. 

“Project SAVER CleanBlue highlights Seaspan’s strong customer partnerships, deep technical expertise, and unique platform integrated with JV partners, such as WattSpan Maritime Technology, in executing complex and large-scale retrofit projects.”

“The successful conversion of the Seaspan Yangtze together with the planned retrofit of its four sister vessels is another important step on our ambitious path towards net-zero fleet operations by 2045,” said Silke Lehmköster, Managing Director, Fleet, Hapag-Lloyd. 

“Together with Seaspan, we are demonstrating that retrofitting existing vessels for low-carbon methanol can be a practical way to reduce emissions in shipping.”
