Green development of inland ships new energy power will become the mainstream

Actively develop LNG-powered ships

The Opinions propose to cultivate a number of influential green intelligent inland waterway ship design, construction, supporting and operation enterprises, create a number of standardized and serialized ship types that meet the needs of different scenarios, form replicable and popularizable experience, and initially build a benign and sustainable industrial ecology. By 2030, the green and intelligent technology of inland ships will be fully promoted and applied, the supporting infrastructure, operation management, business model and other industrial ecology will be improved, standardized and serialized green and intelligent ship types will be built in batches, the industrial chain and supply chain level will be greatly improved, and a modern industrial system for inland ships will be initially established.

"Opinions" pointed out that priority is given to the development of green power technology, LNG-powered ships, battery-powered ships, methanol, hydrogen and other power ships will become the next key development of the technical route.

Accelerate the iterative upgrading of LNG engines for inland river ships, improve the product pedigree of pure natural gas Marine engines, develop gas-electric hybrid technology, and strengthen the control of methane escape and nitrogen oxide emissions. Strengthen the integration and optimization design of LNG power system, and focus on promoting the application of LNG power technology in the coastal, Yangtze River trunk, Xijiang trunk, Beijing-Hangzhou Canal and other medium and long distance cargo ships with more than 2,000 DWT and engineering ships.

We will accelerate the development of battery-powered ships. Strengthen the integration and optimization of Marine power batteries, battery management systems and other technologies, promote technology research on energy-efficient motors, power system networking, and ship charging and replacing, improve the capacity and safety performance of Marine battery powertrain, and focus on promoting the application of pure battery power technology in short-haul inland cargo ships, riverside cruise ships and ships in the Kuhu District. Taking cargo ship as a pilot, the research and application of standardized box-type power change technology are carried out.

Promote the application of methanol, hydrogen and other power technologies. Accelerate the research and development of Marine methanol engines, reduce the emission of unconventional pollutants such as formaldehyde, improve the power range and fuel conversion efficiency of Marine methanol fuel cells, and promote the application of methanol power technology in cargo ships. Strengthen the research and development of Marine hydrogen fuel cell power system, hydrogen storage system, refueling system and other technical equipment, explore the application of hydrogen fuel cell power technology in passenger ships, encourage the use of renewable energy such as solar energy electrolysis water generated green hydrogen.

According to the latest data of the China Shipbuilding Industry Association, from January to August this year, among the new shipbuilding orders in the world, China's liquefied natural gas carriers accounted for nearly 30% of the global market share, reaching 27.2%.

China Sea Oil and Gas Group ship transportation expert Pan Heshun said that in the first half of this year, Jiangnan Shipbuilding and Big Boat Group respectively won international orders, and the new shipbuilding negotiations of Yangtze River shipping industry and merchants industry also made certain progress, forming a new situation of "multi-point flowering", indicating that China's liquefied natural gas carrier construction strength has been greatly improved.

Promote the transformation and upgrading of ship manufacturing

The "Opinions" proposed to speed up the adjustment of industrial structure, encourage the merger and reorganization of inland ship manufacturing enterprises and professional integration, and increase the effective supply of high-quality production capacity. Optimize the layout of inland ship manufacturing industry, promote industrial transfer through cross-regional cooperation, and improve the quality of inland ship manufacturing in underdeveloped areas. Foster a number of inland ship manufacturing backbone enterprises, deepen the integration of inland ship design and construction, accelerate the deep integration of information technology and ship manufacturing technology, explore the mass customized procurement mode of major raw materials such as steel, and vigorously promote standardized, intensive, green and intelligent production.

Several companies have made successful transitions. China State Shipbuilding International has actively adjusted its product mix and developed a variety of green products such as methanol dual-fuel powered ships, LNG dual-fuel powered ships and offshore wind power related products. In 2021, the number of orders for clean energy ship products and high value-added products of Guangsheng International increased by three times year-on-year, and the revenue of green products increased by 70% year-on-year, exceeding 6 billion yuan.
