Feadship, a Dutch shipyard, has been at the forefront of sustainable yacht innovations with recent launches like Project 713, which integrates solar cells for auxiliary power generation alongside diesel-electric main propulsion. This 195-foot yacht is the first of Feadship to carry solar panels, custom-made in the Netherlands, to produce up to 24 MWh annually. Project 713 was ranked 'best in fleet' for sustainability by the Yacht Environmental Transparency Index (YETI), aiming for 'net-zero' yachts by 2030. Feadship's commitment to sustainability is further exemplified by Project 812, the world's first zero-emissions hydrogen-powered superyacht. This groundbreaking vessel operates on fuel-cell technology, providing a week of silent cruising at 10 knots. The shipyard collaborated with various firms to develop a sophisticated system for hydrogen storage and fuel cells. Feadship's focus on eco-friendly designs extends to hybrid-electric propulsion systems seen in recent projects like Project 1012, demonstrating their dedication to advancing sustainable technologies in luxury yacht construction.
