Green and environmental sustainability are perpetual themes in the shipping industry. Driven by the "Dual Carbon" policy and emerging technologies, new energy vessels and green ships have become an irreversible trend. This paper begins by employing the Strengths-Weakness-Opportunities-Threats (SWOT) analysis to review the development trends of domestic green shipping and lithium-battery powered ships. Subsequently, taking the coastal Yangtze River Delta region as a case study, it systematically analyzes the strengths, weaknesses, opportunities, and threats associated with developing the lithium-battery powered ship industry in this area. The study reveals that, influenced by resources, policies, and environmental factors, the coastal Yangtze River Delta region possesses significant advantages for developing this industry. However, it also faces challenges such as inadequate infrastructure, competitive pressures, and technological risks. In response to these issues, this paper proposes targeted optimization strategies to provide insights for the long-term and sustainable development of the lithium-battery powered ship industry.
