T2.1 Addressing the challenges of CO2 shipping, injection and storage
The world is progressively heading to a decarbonized future. Environmental regulations are focus on reducing SOx, NOx but also CO2. As an example IMO has taken a clear position towards a reduction of GHG. By 2025 newbuilt ships have to be at least 30% more energy efficient than those built in 2014. In addition, IMO target of at least 50% GHG reduction by 2050 compared to 2008 levels has been recently adopted.
An efficient and safe CO2 shipping, injection and storage process would facilitate GHG emissions reduction. Bureau Veritas has been extensively working through the full chain to make this feasible.
The transportation of CO2 by ship in liquid form has become a reality. Effectively, to transport massively liquefied CO2 from production location to the site of storage as well as to a site where it may be used to produce synthetic natural gas the shipping industry is to be ready.
The first modern CO2 carrier in service “Coral Carbonic” has a cargo capacity of 1.250 cbm in a type C pressurized vessel and is classified by Bureau Veritas. Bigger ships have been also proposed. Anyhow conditions of transportation and larger cargo volume lead to technical challenges mainly in connection with cargo tank material selection.
On the other hand Bureau Veritas has been involved in different research projects at industrial stage related to injection and storage of CO2 and has developed specific technical guidelines including a certification scheme for the CO2 storage and injection. This guideline advises a certification scheme at different stages of the project, from the selection of the site, the injection and the storage, to the final closure and monitoring of the storage tank.
Different types of certifications are proposed depending on the stage of the project:
- Approval in Principle (AIP)
- Design Approval (DA)
- Certificate of Conformity Certificate for CO2 Injection and Storage Phase
- Certificate of Conformity Certificate for CO2 Injection, Storage and Closure Certificate
- Certificate of Conformity Certificate for CO2 Injection, Storage Monitoring and Post-Closure Certificate
- Certificate of Compliance to the legislations or Modules selected
The certification scheme is compatible with the regulations of all countries in the world.
This paper will present the different aspects and challenges identified during the assessment of such type of projects, including the BV guidelines and classification regulations and other international Rules and regulations applicable.
