Polestar to build batteries for innovative ‘flying’ electric boats

Swedish electric car maker Polestar will provide battery and charging systems for Candela’s highly efficient flying boats. The battery deal will enable Candela to scale up production swiftly, bringing mass-market electric boats one step closer to reality.

In a watershed moment for electrification at sea, the two Swedish companies Polestar and Candela have ventured into an agreement where Polestar will supply the battery and charging systems for Candela’s revolutionary hydrofoiling speedboats.

The deal lets Candela tap into state-of-the-art automotive battery technology and scale up production of its best-selling electric boats.

“To make electric boats mainstream, we need to build thousands of boats every year. Working together with Polestar, we’re able to bring the scale of production and world class engineering from the automotive industry to the marine sector,” said Gustav Hasselskog, Candela CEO and founder.

By combining Polestar’s batteries with Candela’s pioneering electric hydrofoil technology, both companies aim to propel the growth of sustainable electric mobility in society.

“I am fascinated by way Candela’s boats glide elegantly and efficient through, or better, over the water – amazing proof of the great aesthetics and experiences modern, sustainable technology can create. That Polestar will be part of future projects with Candela by supplying an essential part for the innovative propulsion of their boats, is awesome. As a battery supplier to Candela, we can help drive the transition to cleaner oceans and lakes, and electrify waterborne transport,” said Thomas Ingenlath, Polestar CEO.

The deal between the two Swedish companies is an attempt to overcome the two major hurdles for electrifying boating. The first hurdle is the massive energy consumption of conventional powerboat hulls, which so far has resulted in poor performance of electric boats. This obstacle has been cleared by Candela’s hydrofoil technology that cuts energy usage of powerboats by up to 80%.

The second hurdle has been the prohibitively high cost of marine batteries for electric boats.

Electric boatbuilders typically have so far relied on smaller, boutique vendors of marine battery packs. Scarcity and high unit costs of these packs are two factors that have prevented electric boats from achieving parity with ICE vessels.

“Thanks to the partnership with Polestar, we’re able to secure state-of-the-art battery packs for our production ramp-up. As the number of electric vehicles increases worldwide, a steady battery supply will become increasingly important to hold a competitive edge and allow us to compete with combustion engine boats,” added Candela CEO Gustav Hasselskog.

Flying above the water’s surface at 30 knots, the Candela C-8 and P-8 Voyager use up to 80% less energy than conventional boats of the same size, thanks to much reduced water friction. The computer-actuated foils also give them “superpowers”, such as superior seakeeping, zero wake and a silent ride.

After launching the high-volume sales Candela C-8 leisure boat during the fall 2021 and shortly after raising €24 million from EQT Ventures, the Swedish boat maker is now moving into a new production plant where the P-series commercial vessels and C-series leisure boats will be produced.

The battery supply agreement is just the beginning of a broader intended partnership between Polestar and Candela, with both companies committed to exploring further opportunities for future collaboration.
