According to a recent study by Bureau Veritas (BV), carbon capture and storage (CCS) technology has enormous potential to help the shipping industry reduce its CO2 emissions.
n their Feasibility Study and Design: Installing Carbon Capture and Storage Units on Existing Ships white paper, Bureau Veritas set out to study the feasibility of integrating CCS technology onboard in-service vessels.
To study onboard CCS, BV partnered with Wah Kwong and QIYAO Environmental Technology, installing CCS units onboard two in-service ships.
Wah Kwong provided two vessels from their fleet: a 53,000 DWT bulk carrier (Tianjin Venture) and a 176,000 DWT bulk carrier (CSSC Wan Mei).
Using vessel-specific parameters, QIYAO ENVIRON TEC then developed customized CCS units, which were submitted to Bureau Veritas for approval.
The study identified the following challenges for integrating CCS technology onboard:
- Onboard installation: unit arrangement and available space.
- CCS dry weight: installation of CCS equipment and LCO2 tanks.
- Shaft alignment: hull deformation assessment.
- Stability: intact and damage stability assessments.
The study also found that from 2023-2030, with CCS technology onboard, the Tianjin Venture could save ~$305,000 USD. The ship’s carbon capture rate would begin at 10.2%, then rise to 29.5% by 2030.
Similarly, the CSSC Wan Mei could save ~$555,000 USD, with a maximum carbon capture rate of 26.3%. This suggests that applying CCS to in-service vessels is not only feasible, but a potentially economically attractive option for shipowners.
However, customized design of CCS units would be required to ensure each ship reaches the maximum possible CO2 reduction on an economically viable basis.
- According to Bureau Veritas, the analysis illustrates that the application of CCS technology in ships is feasible and creates certain economies under increasingly strict regulations in the future.
- However, the industry must take into account the difficult process of industry chain establishment, such as how collected CO2 is handled, the subsequent development of carbon tax, whether non-EU countries will propose similar regulations, etc.
- Bureau Veritas has no doubt that CCS is already an effective technical solution to decarbonize ships, and a customized design for specific ships will ensure the best savings while meeting regulations.
