Core Viewpoint - The shipping industry is actively deploying emission reduction strategies in response to increasingly stringent carbon emission standards from the International Maritime Organization and the European Union, focusing on transitional technologies and financial support to achieve gradual decarbonization [1][11]. Transitional Technologies Development and Innovation - Transitional technologies for decarbonization in the shipping industry can be categorized into three types: efficiency improvement technologies, transitional fuels, and carbon-neutral enabling technologies [2]. - Specific examples of transitional technologies include hull optimization, waste heat recovery, and the use of liquefied natural gas and biofuels [3][4]. Innovation Technology Cases - Various innovative technologies have been developed to enhance emission reduction effectiveness, such as air lubrication technology and hydrogen-powered vessels, which significantly improve the reduction rates compared to traditional methods [4][5]. - The economic benefits of transitional technologies are notable, as they often involve lower costs compared to zero-carbon technologies, making them more feasible for implementation [5]. Financing Transitional Technologies - Financial support is crucial at all stages of transitional technology development, with different financing tools and models needed based on the risk and return profiles of the technologies [6][9]. - Examples of financing cases include the use of policy-based financial tools, transformation loans, and mixed financing models to support various projects in the shipping industry [7][8]. Domestic and International Financing Cases - International financing cases demonstrate the effectiveness of equity and mixed financing in incubating innovative technologies, while domestic cases show a lack of diversity and granularity in financing tools [10][11]. - The limited number of domestic financing cases highlights the need for improved structures and verification of financing models to support the shipping industry's decarbonization efforts [10]. Recommendations for Future Development - The industry should focus on advancing transitional technologies and recognizing their importance in achieving decarbonization goals, leveraging successful international practices [11][12]. - A comprehensive approach involving risk assessment, appropriate financing tools, and government support is essential for fostering innovation and investment in transitional technologies [12][13][14].
