Candela, a Swedish company known for its pioneering approach to electric watercraft, has officially launched Candela P-12, the world’s first hydrofoil electric ferry, into regular commuter service in Stockholm. The ferry uses cutting-edge hydrofoil technology to reduce energy consumption by 80%, offering a sustainable, zero-emission solution for urban water transport.
The groundbreaking vessel, named Nova, marks a significant step in sustainable waterborne public transport, showcasing Candela’s advanced technology that dramatically reduces energy consumption and environmental impact. The ferry, part of a pilot project, operates between Tappström on Ekerö and Stockholm’s Stadshus, promising faster and eco-friendly commuter travel.
The unique hydrofoil system enables Nova to rise above the water’s surface, minimizing drag and reducing energy consumption by up to 80% compared to traditional ferries. This translates into a smoother, quieter, and more efficient ride with minimal wake, allowing for higher speeds in urban areas. As a result, Nova can operate up to 25 knots (approximately 46 km/h), surpassing conventional diesel ferries in speed and sustainability.
Diab’s lightweight and strong core material is central to Nova's design and performance. By incorporating Diab’s advanced composites, Candela has been able to construct a vessel that is not only capable of high-speed hydrofoiling but also robust and energy-efficient. Diab’s core material contributes to the overall weight reduction of the ferry, allowing it to maximize battery life and reduce the need for extensive charging infrastructure. This innovative material choice supports Candela’s goal of delivering emission-free watercraft with superior durability and minimal maintenance requirements.
The ferry can accommodate 25 passengers and completes the 15 km route between Tappström and Stadshuset in just over 30 minutes. This efficient service significantly reduces typical commuting times, demonstrating how hydrofoil technology can revolutionize urban water transport. The Nova ferry runs entirely on renewable electricity and is powered by Candela’s proprietary C-POD motors, which feature a direct-drive system for improved efficiency and minimal noise.
In collaboration with Candela and Trafikverket, Stockholm's regional government supports this pilot initiative as part of a broader strategy to introduce emission-free and cost-effective transit solutions. If successful, hydrofoiling electric ferries could expand to other routes, unlocking the potential of underutilized waterways and transforming the city’s transit landscape.
Candela’s partnership with Diab showcases the importance of innovation and collaboration in creating sustainable, forward-thinking transport solutions. The launch of Nova represents a significant achievement in eco-friendly engineering, setting a precedent for future projects aimed at reducing emissions and enhancing the efficiency of public transport. With the integration of Diab’s high-performance materials, Candela’s Nova is not just a technological feat but an example of what is possible when sustainability and innovation are combined.
