This report summarises the dissemination activities conducted for Work Package (WP) 5 of the EverLoNG project.

The EverLoNG project set out to develop and demonstrate the SBCC technology. For this, they installed a demonstrator onboard the Seapeak Arwa LNG Carrier (chartered by TotalEnergies) and the SSCV Sleipnir. The demonstrator’s operational risks were assessed in a HAZOP workshop. Full-scale concept designs were further developed for a new build LNG Carrier and the SSCV Sleipnir based on the same technology and working principles and assessed in dedicated HAZID workshops.

The objective of Task 5.3 was to publish and disseminate the knowledge gained through these risk workshops amongst the wider maritime community, thereby accelerating the uptake of SBCC in a safe and certifiable manner.

This report has been prepared to meet the EverLoNG project deliverable D5.2.3, which involves identifying common safeguards from the risk assessments. It also contributes to fulfilling D5.3, which entails summarising the learnings from Work Package 5 and disseminating the insights gained to relevant international regulatory bodies. The report builds upon previous deliverables and activities in WP5.

The main safety hazards associated with an SBCC installation pertain to loss of containment in the chemical systems used during the CO₂ capturing process and the hazards linked to loss of containment in systems employed for processing, storing, and off-loading captured CO₂.

The report addresses preventive and mitigating safety barriers that should be considered to reduce the frequency and consequences of hazardous events related to SBCC installations. The evaluation is based on a comprehensive assessment of hazardous events identified through multiple HAZIDs
conducted in the EverLoNG project, which must be mitigated to ensure the safety of the ship and its crew.

This report has been prepared to meet the requirements of EverLoNG project deliverables D5.1.1 and D5.1.3 and consists of three main sections: Identify applicable safety and environmental standards and codes / Major hazard of CO₂ loss of containment / Assessment of technology novelty.

This deliverable concentrates on the definition of full chain CCUS cases that will be evaluated in EverLoNG. Definition contains ship types, port location, sailing route, the Ship Based Carbon Capture (SBCC), onshore facilities for CO₂ handling and the transport of CO₂ to either storage or utilization.
The defined cases will be evaluated by life cycle analysis (LCA) and techno-economic assessments (TEA) in WP4.

Currently, there are no guidelines on the logistics of CO₂ and solvent receival from the ship to the port and the loading of reclaimed or fresh solvent from the port to the ship. These challenges must be solved before a larger port network of CO₂ receival- and solvent reclaiming facilities can be organised

This report introduces several different offloading alternatives. It shows that the ports have options on how the CO₂ could be transported, depending on the ship type, volumes of CO₂, size, and number of ships with SBCC annually. The infrastructure for further transport of CO₂ needs to be identified and ready before the port can receive CO₂ from the ships.

This publication presents some of the findings from the third work package (WP3) of the research project EverLoNG, which aims to expedite the adoption of ship-based carbon capture technology on commercial vessels. The EverLoNG project is part of the Accelerating CCS Technologies (ACT) program, which seeks to promote the emergence of CCUS through transnational funding, targeted research, and innovation. The EverLoNG project is supported by several organizations, including the Federal Ministry for Economic Affairs and Climate Action (Germany), the Research Council of Norway, the Ministry of Economic Affairs and Climate Policy (Netherlands), the Department for Business, Energy & Industrial Strategy (UK), and the U.S. Department of Energy, all of whom have provided funding for this project.

There is growing interest in ship-based carbon capture (SBCC) as route to decarbonisation of global shipping fleets. This leads to the need for the development of an international CO₂ shipping network, and hence interoperability between regions.

The EverLoNG project aims to set up a CO₂ Shipping Interoperability Group (CSIG) to review and discuss the barriers and drivers to achieving this international interoperability. Three workshops will be run over the duration of the EverLoNG project, looking at the learning from the transport of other liquified gases, especially LNG and LPG, the role of international standards and regulation, and techno-economic requirements.
