The Technical Seminar on Onboard Carbon Capture and Storage (OCCS), organized by The Future Fuels and Technology Team, was held at IMO Headquarters on 11 September 2025 to share technical knowledge between stakeholders on the current state of OCCS technologies. The hybrid event was attended by around 400 participants.
The diverse group of speakers at this event shared their perspectives on various aspects of OCCS technologies including practical experiences from existing onboard projects, development of the OCCS value chain, alternative carbon capture technologies and the role of OCCS within the broader context of the shipping industry.
The presentation slides from the seminar are available below:
- IMO’s ongoing work on onboard carbon capture and storage (OCCS) systems – IMO Secretariat
- Developing solutions for OCCS: insights from real-ship projects in safety, operation, and regulation – Mr. Joseph Ohg (PANASIA, Republic of Korea) and Mr. Joonghun Kim (Korean Register, Republic of Korea)
- Experience with the use of OCCS onboard Clipper Eris – Mr. Sigurd Jennsen (Wärtsilä) and Mr. Tor Øyvind Ask (Solvang ASA, Norway)
