Research on adoption of hybrid electric tugboats for achieving carbon reduction emissions in Taiwan

Taiwan has initiated carbon reduction measures for the operation of equipment in domestic commercial ports. Within commercial ports, it is essential for tugboats to operate their diesel engines at low speeds during operations, a practice that often leads to unnecessary energy consumption. In contrast to traditional diesel-powered tugboats, contemporary gasoline-electric hybrid tugboats can operate efficiently at low loads. The implementation of electric drive systems significantly diminishes fuel consumption and exhaust emissions. The adoption of hybrid propulsion systems presents a viable solution. This study aims to assess the perspectives of domestic industry stakeholders, government entities, and academic institutions regarding this matter, and to discuss the subsequent formulation of carbon reduction strategies for tugboats operating in port areas. Furthermore, it seeks to encourage industry investment in scientific research focused on achieving net-zero carbon emissions.
