CO₂ logistic by ship III

Background
The CO₂LOS III project is a continuation of the CO₂LOS II project that was carried out in 2019-2020 and utilizes relevant results from this project. Some topics were selected from the CO₂los II project to be investigated in detail, and some new partners joined the project and provided more opportunities to increase the scope after the project application was submitted to CLIMIT. The background to the CO₂los projects is that the participants wanted to investigate new ship transport solutions with the potential for significant cost reduction and increased energy efficiency adapted to a society in constant technological development. CO₂LOS builds on experience from previous projects and knowledge both within CO₂ handling and ship solutions. SINTEF Tel-Tek has worked with CO₂ ship transport for a number of years with projects such as ALIGN, ZEP and NORDICCS Brevik Engineering has since 1997 worked with solutions for the transport of LNG and has extensive experience with ship design within FPSO/FLNG (“Floating Production, Storage and Offloading”)/(“Floating liquefied natural gas”), special ships and cargo ships.
The scope of the CO₂LOS III (CO₂ Logistics by Ship Phase III) project is to further increase the knowledge base for future ship-based CCS projects’ logistics operations.

Objectives
CO₂LOS II and CO₂LOS III considers issues needed to be addressed in order to reduce the cost for CO₂ ship transportation. The projects seek to fill the gap between research and specific CCS projects and will as such focus on technology transfer rather than technology development. The overall aim is to provide knowledge of how new shipping technology can enhance CO₂ logistics to make it a viable solution to transport CO₂ for CCS.

Activities
The project consists of 7 work packages, each of which covers areas within CCS logistics where increased knowledge is believed to accelerate the development of future CCS projects. 2 final reports were prepared – summarizing the work in the work packages, a public report and a project internal report. In addition, a cost tool was developed and shared with the partners. The work packages are:
WP1 – Cost Estimation Tool for CCS Scenarios
WP2 – Tank Arrangement for Large CO₂ Carriers
WP3 – Floating CO₂ Terminals
WP4 – Zero Emission Shipping
WP5 – Roadmap to Unmanned FSI
WP6 – Potential for Batchwise Injection
WP7 – Rules and Regulations for CO₂ Shipping

The work packages leads have had weekly meetings to discuss issues and progress at Teams.
The project had monthly technical meetings (Teams) with the industry partners to have discussions about the research and the ongoing work and also to inform the partners of the project progress. In addition, several workshops with partners and external has been arranged, for specific topics like offshore unloading and batchwise injection.
We have had 4 consortium meetings, 2 physical, including a plant tour to the CO₂ storage and quay facilities by Yara at Herøya in Porsgrunn and also a tour in SBMs office with a presentation of their work.

Results
The project has investigated many aspects within ship transport of CO₂, especially tank design of large ships, offshore unloading and floating terminals. The roadmap for unmanned FSI is also an important contribution to show how such a development is envisaged. A description of the tool and input parameters for the tool are described in reports, and like the other main findings in the project, have been made publicly available. The entire final report can be downloaded at www.sintef.no/co2los

The project aimed to use knowledge from the partners and existing logistics chains together with knowledge about CO₂ and to seek to reduce the costs of CO₂ transport. We feel this has been achieved, and we have gained a good tool for assessing various cases/scenarios and also which we hope we will be able to develop further in Co2los IV to deal with CO₂ emissions in addition to costs.

Future plans
During the work on CO₂lOS I-III, several new partners have found the project interesting, and are joining the consortium during the projects. We are now in the application phase of CO₂LOS IV, and new partners have shown interest in joining. Researchers, engineering companies, stakeholders and industry are working together to optimize the CO₂ logistical chain. The main purpose of CO₂LOS IV is to use the knowledge and tools we have acquired and development in Co2los II and Co2los III to create methods to assess different cases/scenarios and also develop the decision-making basis to include CO₂ emissions and LCA.
