The first electric flying ferry will make Stockholm’s river public transport faster than cars and the metro
Marine technology company Candela has released the first images of what will be the world’s fastest, longest and most energy-efficient electric vessel. The Candela P-12 shuttle, as this innovative vessel is called, will ferry citizens between Stockholm’s sprawling suburb of Ekerö and the city center over the coming year. Flying on water, the 30-passenger electric vessel has a speed of 30 knots – considerably faster than any other electric vessel in the world. It also allows faster travel than the metro and bus lines it competes with, while being infinitely more energy efficient than diesel ships currently serving the same route. Perhaps most importantly, the ship is faster than traveling by car during rush hour.
The secret to its high speed and long range is the three carbon fiber wings that extend under the hull. These active hydrofoils allow the vessel to lift above the water, thereby decreasing drag.
500% more efficient ships
Candela’s technology reduces energy per passenger-kilometre by 95% compared to current vessels, enabling unprecedented range of 50 nautical miles at service speed. Using the equivalent of 0.1 kWh of electricity per passenger-kilometre, the ship is more energy efficient than a hybrid electric bus. Plus, with DC charging up to 200kW, it can charge its battery in less than an hour.
More importantly, the ultra-sharp carbon fiber sheets will cut commute times in half for many commuters.
With the ability to cover even Stockholm’s longest high-speed routes, the Candela P-12 shuttle will be used by the to shorten the journey between Stockholm’s growing suburb of Ekerö and the city centre. Currently a 55-minute journey by bus, metro or conventional ferry (or even by car during rush hour), the Candela P-12 shuttle will cover the 15 km journey in just 25 minutes, allowing the commuter to save an average of 50 minutes a day.
– This will have a huge positive impact on people’s lives – you can work an extra hour or pick up your children from school an hour earlier, says Erik Eklund.
As the Candela P-12 Shuttle hydrofoil creates a near-zero wake, it was granted an exemption from the 12 knot speed limit, allowing it to fly around downtown without causing damage to other vessels or shorelines. sensitive. In fact, the tiny propeller wash is considerably smaller than the wake of conventional passenger ships traveling at slow speeds.
Get rid of seasickness
The first electric flying ferry will also elevate the passenger experience to a whole new level, thanks to the most advanced computer system to be found in a passenger boat. Those prone to seasickness will appreciate the extremely smooth ride in inclement weather. Flying silently over the waves, the Candela Flight Controller – a computer that regulates hydrofoils 100 times per second – provides a smooth, smooth ride over the waves that would make many feel uncomfortable.
– There is no other ship that has this kind of active electronic stabilization. Flying on the P-12 shuttle in rough seas will feel more like being on a modern express train than on a ship: it’s quiet, smooth and stable, says Erik Eklund, Vice President, Commercial Ships at Candela.
The Stockholm region will operate the first P-12 shuttle ship for a nine-month trial period in 2023. If it lives up to the high expectations placed on it, the hope is that the city’s fleet of more of 70 diesel ships will eventually be replaced by P-12 Shuttles – but also that ground transportation from congested highways can move to waterways.
-Maritime traffic is the most popular public transport in the region, and I want to develop it. But we need better technology to travel faster and reduce climate impact. Therefore, we are happy to try this new technology for river traffic. This project can contribute to solutions that we can use in Stockholm, but also offers export and job opportunities in the Stockholm region, says Gustav Hemming, Vice President of the Stockholm Regional Executive Council.
The return of river transport
Since faster and cheaper steam trains began to replace expensive and slow coal-powered ocean liners in the 1850s, urban transport has come to rely on land vehicles – even in cities like Stockholm, San Francisco and New York, where the waterways provide natural cross-connections between regions and boroughs.
With Candela’s P-12 shuttle, the current status quo will once again be challenged. At peak times, the ship is faster than buses and cars on many routes. Thanks to the efficiency of the hydrofoil, it can also compete on mileage costs; and unlike new metro lines or highways, the flying electric super-ship can be inserted onto new routes without massive infrastructure investment – all that is needed is a dock and electric power.
The practical size of the P-12 shuttle – with a comfortable and airy cabin for 30 seated passengers – adds to its versatility. In Stockholm, passenger ships have an average occupancy rate of 17%, which means that a 300-passenger ship only carries about 50 people most days.
Candela’s vision is to replace the current large, mostly diesel-powered vessels with nimble fleets of faster, smaller P-12 shuttles, allowing more frequent departures and more passengers carried, at lower cost to the operator. On the Stockholm-Ekerö route, Candela’s proposal is to replace the current pair of 200-person diesel vessels with at least five P-12 shuttles, which would double potential passenger volume and reduce operating costs.
– Instead of two departures per day, there would be a P-12 shuttle leaving every 11 minutes. This allows commuters to ignore timetables and simply go to the dock and wait for the next boat, says Erik Eklund.
Mass production for mass transit
Candela will lay the carbon fiber keel of the first-ever Candela P-12 shuttle at the company’s new automated factory in Rotebro, outside Stockholm, towards the end of 2022. After initial testing, the first commuters from Stockholm will embark on the 40-foot boat in 2023.
The first P-12 shuttle would be followed by many more as mass production ramped up at the company’s Rotebro plant. Using already streamlined production methods for Candela’s pleasure boat manufacturing, Candela aims to eventually spit out hundreds of P-12 shuttlecraft per year. Company sees huge demand from more than 600 cities, municipalities, ship operators and urban developers who have already expressed interest in the P-12 shuttle as a faster, cheaper and greener alternative to ships existing diesel or ground transportation.
