The shipping industry is undergoing a profound green transformation
Nov 12,2021
1. Background and driving force of green transformation
The green transformation of the shipping industry first stems from the world's profound understanding of climate change. With the signing of international agreements such as the Paris Agreement, governments have pledged to reduce greenhouse gas emissions to achieve the goal of controlling the global average temperature rise to within 1.5°C or 2°C above pre-industrial levels. As the main mode of transportation for international trade, ships emit pollutants such as carbon dioxide, nitrogen oxides and sulfur oxides, which pose a serious threat to air quality, marine ecology and even the global climate system. Therefore, it has become a consensus of the international community to promote the development of the shipping industry in a low-carbon and environmentally friendly direction.
Technological progress has made this green transformation possible. In recent years, the rapid development of new energy technology, intelligent technology and material science has brought revolutionary changes to ship design, construction and operation. The emergence of new ships such as electric ships, liquefied natural gas (LNG) powered ships, hydrogen fuel cell ships, and wind and solar auxiliary power systems indicates that the shipping industry is gradually getting rid of its dependence on fossil fuels and transforming to clean energy.
2. Application and innovation of green technology
In terms of the innovation of ship power systems, liquefied natural gas, as a relatively clean fossil fuel, has been widely used in new shipbuilding projects, especially in large ships such as container ships, tankers and passenger ships. At the same time, electric ships and hydrogen fuel cell ships have shown great potential in short-distance transportation, inland shipping and fisheries. They are not only zero-emission, but also low-noise, and significantly more environmentally friendly. In addition, the application of some cutting-edge technologies such as air lubrication systems, energy recovery systems and advanced ship design software has also effectively improved ship energy efficiency and reduced energy consumption and emissions.
The application of intelligent technology is another highlight of the green transformation of the shipbuilding industry. By integrating technologies such as the Internet of Things, big data, and artificial intelligence, ships can achieve more accurate navigation control, energy efficiency management, and fault warning, thereby further optimizing navigation routes and reducing unnecessary energy consumption while ensuring safety. Smart ships can also automatically adjust the navigation speed according to sea and weather conditions to achieve energy efficiency.
