Shanghai has successfully explored a new path to reduce carbon emissions in the shipping industry, installing carbon capture systems on cargo ships to recover carbon dioxide

Shanghai is also contributing new solutions to the global shipping industry to reduce carbon emissions. A few days ago, the "Changding" container ship from Europe docked at Yangshan Port in Shanghai, and unlike in the past, the "Changding" docked at the port this time not only to complete the container operation, but also unloaded a gas tank about two container sizes.

It is understood that this tank contains liquid carbon dioxide collected by the newly installed carbon capture system of the "Changding". The successful unloading of the tank marks the formation of a closed loop from fuel consumption to carbon dioxide recovery and utilization of ocean-going vessels, and also means that the "Shanghai Plan" experiment for carbon reduction in the global shipping industry has been successful.

According to reports, the "Changding" container ship has been ten years old, the installation of carbon capture system by China's independent research and development, design and construction, mainly using organic amine cycle adsorption technology, carbon dioxide from the ship's main engine emission of mixed gas, the cumulative voyage to Europe 35,000 nautical miles, carbon dioxide comprehensive capture rate of up to more than 80%.

It is understood that sea freight is the most important mode of transportation in international trade, and at present, the global fleet is still dominated by traditional fuels. With the increase of international trade, the increase in the size of the fleets of various countries and the increasing size of ships, the carbon emissions of ships have attracted more and more attention from all countries. According to the International Maritime Organization, shipping accounts for about 3% of global CO2 emissions. A single cargo ship with a capacity of 20,000 TEUs consumes about 10 tons of heavy fuel oil per hour when sailing.

In order to promote the reduction of carbon emissions by shipping enterprises, in recent years, countries have developed green shipping by levying carbon taxes and implementing carbon emission quota trading. At the same time, there is a strong demand for the reconstruction of decarbonization and desulfurization of traditional energy ships, and various new energy ships powered by LNG, green methanol, green ammonia, lithium batteries, etc. are competing to appear.

According to the analysis of relevant experts, compared with the power system of new container ships and rebuilt ships, the initial investment and operating costs of installing carbon capture systems are lower, which is one of the most cost-effective carbon reduction methods, which can meet the needs of carbon emission reduction in the whole life cycle of ships, and has broad market prospects. The successful practice of the "Changding" container ship will provide new ideas for carbon reduction in China's shipping industry, and will also contribute to the green development of the global shipping industry.
