The Japanese shipbuilder Naikai Zosen Corporation has been selected for the 'Zero Emission Ship Construction Promotion Project,' which aims to establish a domestic production system in Japan for zero-emission vessels by 2028. This initiative is part of Japan's commitment to achieving net-zero greenhouse gas emissions by 2050. The project involves utilizing various energy sources such as hydrogen, ammonia, and wind propulsion for international shipping. Success in the project's fiscal 2024 call for applications has seen prime contractors and small-medium enterprises investing in zero-emission ship technologies. Moreover, Naikai Zosen's involvement in constructing vessels for the Japan Self-Defense Force (JSDF) showcases a dual-purpose focus on both commercial and defense shipbuilding. The JSDF plans to strengthen its transport capabilities through civilian vessels and potential future adoption of low-emission technologies, aligning with the overall goal of reducing carbon emissions. The project's emphasis on green initiatives and technological advancements signifies a significant shift in Japan's shipbuilding industry towards sustainability and environmental responsibility.
