Hybrid marine propulsion combines traditional fuel engines with electric power systems to enhance the efficiency and reduce emissions of marine vessels. This technology allows ships to operate on either power source or a combination of both, optimizing performance based on operational needs and environmental conditions. By integrating batteries and electric motors, hybrid systems can lower fuel consumption and minimize noise and air pollution. Many modern vessels, including ferries and cargo ships, are adopting this approach to meet stricter environmental regulations and improve sustainability in the maritime industry.
