Assessing sustainable decarbonization strategies for green shipping using tugboat owner investment in hybrid power systems in ports in Taiwan

Abstract

AbstractDecarbonization has significant operational implications for ships, fuel resources, and ports. Sustainable management is highly prioritized by ship owners and port authorities. The shipping industry must develop appropriate strategies to achieve zero carbon emissions by 2050 and support the 2030 United Nations sustainable development goals. Tugboats, a ubiquitous vessel in Taiwanese ports, were selected as the subject of this study. Implementing hybrid power systems in response to the growing trend of carbon reduction was explored. This study involves various stakeholders in Taiwan, including ship owners, port agency representatives, and other relevant parties. Assessing investment costs, market demand, and policy guidance is highly significant. Establishing a positive cycle is necessary to encourage tugboat operators to adhere to sustainable management practices and environmental protection measures. This entails providing incentives through policy measures that enable tugboat operators to gain cost advantages and balance environmental, economic, and societal needs within an expanding market.
