Research on the Green Development of Port Mechanical and Electrical Equipment under the "Dual Carbon" Strategy

Abstract

After the goals of carbon peaking and carbon neutrality were put forward, the pressure of emission reduction in the shipping industry has been accelerated to transmit to ports, and the green and low-carbon transformation of mechanical and electrical equipment has thus become an important starting point for the implementation of emission reduction. This paper reviews the carbon reduction practices of typical ports at home and abroad, and examines the application effects and bottlenecks of core technologies from four directions: new energy power machinery, braking energy recovery, multi-energy complementary systems, and ship shore power. Analysis shows that port decarbonization is entering a new stage of multi-technology collaborative integration, and the supply side, the energy use side, and the management side need to exert force simultaneously; the policy dividends, market traction, and technology iteration during the transformation window period bring both opportunities and challenges. Based on this, the paper puts forward suggestions on connecting with policy tools, tackling core technologies, unifying standards and norms, and implementing whole-life-cycle digital management of equipment, for reference in the green upgrading of ports.
