Hybrid vessels are ships that use a combination of traditional fuel engines and alternative energy sources, such as batteries or fuel cells. This design allows them to operate more efficiently and reduce emissions, making them more environmentally friendly compared to conventional vessels. These ships can switch between power sources depending on the operational needs, such as sailing in busy ports or open waters. By integrating technologies like solar panels or wind turbines, hybrid vessels aim to minimize their carbon footprint while maintaining performance and reliability in maritime operations.
