Stockholm has recently made a significant advancement in urban transportation with the launch of its first electric hydrofoil ferry, the Candela P-12 Nova. This innovative vessel is designed to transform how residents and visitors navigate the city’s waterways, aiming to reduce both emissions and travel times. The Candela P-12 Nova began its service on November 1, 2024, completing a 15-kilometer route from Tappström to Stockholm’s City Hall in just over 30 minutes. This represents a substantial improvement in commuting efficiency, cutting travel time in half compared to traditional ferry services. The introduction of this ferry marks a pivotal moment for Stockholm as it seeks to modernize its public transport system while prioritizing sustainability.

The Candela P-12 Nova operates using advanced hydrofoil technology that allows it to "fly" above the water's surface. This is achieved through computer-controlled hydrofoil wings that lift the hull out of the water, significantly reducing drag and energy consumption by up to 80% compared to conventional vessels. Gustav Hasselskog, founder and CEO of Candela, described this innovation as a “paradigm shift for urban transport.” The ferry cruises at speeds of up to 25 knots, making it the fastest electric ferry in operation globally. This speed not only enhances the efficiency of public transport but also encourages more residents to consider waterborne travel as a viable alternative to road transport

Currently, Stockholm's fleet of approximately 70 public transport vessels consumes more fossil fuels than the city’s buses and trains combined. The introduction of the Candela P-12 Nova addresses this challenge by operating entirely on renewable electricity. Additionally, its design minimizes wake generation, allowing it to travel at higher speeds within city limits without causing disruptions or damage to the waterways. The ferry's near-silent operation is attributed to its electric C-POD motors, which eliminate mechanical transmission noise, further enhancing the passenger experience. This focus on sustainability and efficiency aligns with Stockholm's broader goals of reducing carbon footprints and promoting environmentally friendly transportation options.

The pilot project for the Candela P-12 Nova will run through fall 2024 and resume in spring 2025. It is a collaborative effort involving Candela, Trafikverket (the Swedish Transport Administration), and Region Stockholm. The initiative aims to demonstrate how hydrofoil technology can create faster, more affordable, and emissions-free maritime transit options. As cities worldwide grapple with congestion and pollution from traditional transport methods, Stockholm's pioneering approach could serve as a model for urban centers looking to revitalize their waterways and improve public transportation systems. With international interest already generated—Candela has received orders from countries such as Saudi Arabia and New Zealand—the success of this project could lead to a broader adoption of electric hydrofoil technology across global cities.
