Readiness and challenges of carbon capture technologies based on the shipping industry.

In the context of carbon emission reduction in the shipping industry, CCUS technology can modify ships to reduce carbon emissions, providing a new direction for the green development of the shipping industry. Based on this, this paper investigates the technology related to carbon capture on ships, firstly puts forward the applicable requirements of carbon capture technology; and analyses the adaptability of the existing carbon capture solutions to the shipping industry; and discusses the development prospect of carbon capture on ships through the three challenges of space utilisation, safety, and economy; and finally analyses the related policies. After analysis and discussion, this paper concludes that the alcohol-amine method is the most suitable carbon capture solution for ships, but there are challenges in economics and space utilisation. The future research direction lies in optimising the performance of the absorber, improving the energy efficiency of the system and solving the CO 2 storage problem. • It analyzes the current situation of the development of the carbon emission reduction business in the shipping industry, and introduces the application of carbon capture, utilization and storage technology (CCUS) in the shipping industry; • The applicable requirements for carbon capture on ships are proposed with regard to the ship's own characteristics; • Carbon capture process types are described in detail and the feasibility of different processes applied to the shipping industry is analyzed; • Summarises the existing cases of carbon capture on board ships and describes the challenges faced by carbon capture technology on board ships.
