Interest in new environmentally friendly marine technologies is growing globally. The ongoing transformation will provide a market for new technological applications in the marine industry. In particular, the competitive advantage can be achieved through energy-efficient solutions, which reduce investment and operating costs while meeting demanding environmental regulations and improving the reliability of the system. By adding an energy storage component to hybrid applications and optimising system control technology, the energy, cost-effectiveness and performance of shipping operations can be significantly improved. Until now, energy storage has not been more widely used in marine applications. However, rapid development in battery technology has increased interest in energy storage, especially in hybrid solutions for short-sea shipping. In addition to the ship’s energy storage system, future ship types can also benefit from the production of renewable energy in the port area. This requires support schemes for hybrid and full-electric ships in port. The port support system can provide rapid charging and direct access to renewable energy sources in the region. An important factor in optimal costs is also the flexible integration of the local electricity grid.This research project will explore and develop new energy-efficient propulsion solutions for ships using hybrid technologies and energy storage facilities. In addition, the project will also explore the necessary port infrastructure for the integration of the vessel into the shore-based electricity grid and renewable energy sources. The optimal operation of such a system also requires the extension of the system’s data management and monitoring to both ports and ships, which is also one of the subjects of the study. Research methods include modelling and simulation, analysis of the performance of different system options under different operating conditions and small-scale laboratory demonstrations.
