The Development of Electric Ship Industry Further Speeds Up
By Huang Zhaoxia, CCS Wuhan Rules & Research Institute
The green transformation in transportation field has become a trend in recent years . The shipping industry is turning to electric ships for green development since they have such advantages as green, environment-friendly, able to realize zero emission . In addition, electric ships are safe, convenient, high efficiency and low-cost, without diesel leakage . Hence, they are an effective choice for green transformation of inland waterway shipping .
Currently, China continues to improve the independent research and development capabilities of battery electric ships, has broken through many key technologies and reached the world’s advanced level . There are pilot applications in passenger ships, ferries, official ships and bulk carriers,showing good demonstration results . So far, more than 190 battery electric ships for inland waterways have been built, and more than 60 are under construction or planned to be built . The application types include passenger ships, ferries, public service ships and dry bulk carriers, all of which use lithium iron phosphate batteries as power .
The White Paper on the Development of China Electric Ship Industry (2021) show that, the penetration rate of lithium batteries in ships is expected to reach 0 .55% and 18 .5% in 2022 and 2025, respectively . The market scale of electric ships in China will be on the rise . Before loaded onboard, lithium batteries must be tested and certified by CCS, and battery plants and raw materials must be strictly checked . As of March 2022, CCS had is s ued 83 type approval certificates for lithium battery products, and the certified products cover battery cells, modules, BMS and battery packs .
Through many years of efforts, CCS has had a strong capacity in the application and development of battery powered ships, and has full time staffs responsible for this product, and they all have rich filed practice experience and good abilities of theoretical analysis and practical application . Therefore, CCS is able to provide technical support and safety guarantee for the application of lithium batteries to ships .
Under the target of “carbon dioxide peaking and carbon neutrality”, the urgent demand for the application of battery powered ships and the requirement for the safe and healthy development of battery powered ships, CCS has overall promoted the research on the safety of applying batteries to ships in recent two years . It is further constructing the digital rule and standard system framework of “one rule and one platform” for battery powered ships .
