World's first fossil-free superyacht packs power of 88 Tesla vehicles

SY Zero is the world’s first fossil-free sailing superyacht, nearing completion with a planned launch at the end of 2025. Measuring nearly 70 meters, the yacht is the product of over 60,000 hours of research and development by Vripack Yacht Design, Vitters Shipyard, and other collaborators. It is powered entirely by renewable energy sources—wind, solar, and thermal—eliminating the need for fossil fuels. A key feature is its five megawatt-hour energy storage system, comparable in capacity to 88 Tesla vehicles, which powers all onboard functions including propulsion, lighting, and utilities. The yacht collects energy through innovative methods such as hydro-generating thrusters that harness water flow while sailing, a 100-square-meter hybrid solar panel array with 60% efficiency, and a wind turbine utilizing offshore airflow. The project aims to demonstrate that high standards of comfort, design, and performance can be achieved without fossil fuels, serving as a model for sustainable naval
