Flying electric ferries battle to smoothly sail commuters over the wave crests
As electric boats slowly gain market share among recreational boaters, a different breed of silent, efficient speed boats is now targetting commuters. Hydrofoil electric ferries are coming to a river or lake near you, and multiple companies are working to make it happen.
I’ve had the pleasure of covering electric boats for years, where I’ve seen just about everything the nascent industry has to offer. But it’s the hydrofoil electric boats that are making the biggest departure from the norm.
Compared to traditional V-hull or catamaran vessels routinely used as ferries, hydrofoil boats use significantly less energy to travel the same distance on the water. Hydrofoils, which work like an airplane’s wing placed underwater, lift the entire boat’s hull into the air. With significantly lower resistance, the boat essentially flies while using as little as 20% of the same energy required by a planning boat.
Hydrofoil boats have been around for decades, but more recent advances have replaced older internal combustion engines with electric motors, taking these boats to the next level.
The biggest name in the game is undoubtedly Stockholm-based Candela, which first sailed its prototype hydrofoil electric boat back in 2016 and has been in production since 2018. The company began with multiple models of electric speedboats for recreational boating. Now, its newest model, the Candela P-12, is going commercial for use as a ferry in rivers, lakes, and archipelagos like around its home waters in Stockholm.
The P-12 has been undergoing water trials since last year, ahead of its first commercial operations.
One of its first operators will employ it on the world’s cleanest lake, Lake Manapōuri in New Zealand, where it is expected to replace 240 tons of CO2 emissions each year by replacing combustion engine boats.
While Candela undoubtedly leads the industry, other hydrofoil electric boats have cropped up in the last couple years. Vessev, an Auckland, New Zealand-based startup, has just announced the successful completion of two weeks of intensive water testing for its VS-9 electric hydrofoil ferry.
“We have been pushing the VS—9 less than two weeks after its first flight and she has been ticking all the boxes and more,” announced Vessev CEO Eric Laakmann earlier today. “On some of our test sessions, we had 25 knots gusting 35 with wind waves to match and she was cruising over the waves.
According to the company, which released the video below, the testing occurred in sea states featuring chop and waves averaging around 75 cm (2’6″) and peaking at 100 cm (3’3″).
The VS-9 is designed to transport up to nine passengers, though Vessev claims to be developing a much larger 100-passenger hydrofoil ferry for larger operators.
San Francisco, California-based electric boat startup Navier also plans to target the commercial ferry market with its first model.
Debuted in 2023, the Navier N30 announced its first official pilot program earlier this year. The hydrofoiling electric boat was said to be partnering with payment platform Stripe to ferry its employees from San Francisco’s outskirts to the downtown area.
The plan would showcase how the normally one-hour drive could be transformed into a much more efficient half-hour ferry ride on a hydrofoil electric ferry.
Electrek’s Take
I’ve test-driven a few hydrofoil electric boats, and I’ve always been amazed by how easy they are to operate and how smooth the ride is.
On Candela’s electric boats, I’ve been able to cut right across the wakes left by cruise ships while feeling barely a ripple.
Ferries can replace a significant number of cars in waterside cities, but making the experience more pleasant and efficient is key to getting more drivers out of their cars. With hydrofoil electric boats, not only do the journeys use significantly less energy, but they’re also smoother and more enjoyable. I’ll admit to being prone to seasickness, yet I’ve never gotten even a tad bit queasy on a hydrofoil electric boat.
Check out one of my last hydrofoil electric boat test drives below, where I took the Candela C-8 for a spin around Stockholm.

Turning cheap daytime solar into electricity you can actually use at night just got a lot cheaper. A new analysis from energy think tank Ember shows that utility-scale battery storage costs have fallen to $65 per megawatt-hour (MWh) as of October 2025 in markets outside China and the US. At that level, pairing solar with batteries to deliver power when it’s needed is now economically viable.
Battery storage costs have fallen dramatically over the past two years, and the decline continues. Following a steep decline in 2024, Ember’s analysis indicates that prices continued to fall sharply again in 2025.
The findings are based on real-world data from recent battery and solar-plus-storage auctions in Italy, Saudi Arabia, and India, as well as interviews with active developers across global markets.
According to Ember, the cost of a whole, grid-connected utility-scale battery storage system for long-duration projects (four hours or more) is now about $125 per kilowatt-hour (kWh) as of October 2025. That figure applies to projects outside China and the US. Core battery equipment delivered from China costs around $75/kWh, while installation and grid connection typically add another $50/kWh.
Those lower upfront costs have pushed down the levelized cost of storage (LCOS) to just $65/MWh. Ember’s calculation reflects real-world assumptions around financing costs, system lifetime, efficiency, and battery degradation.
Cheaper hardware isn’t the only reason storage costs are falling. Longer battery lifetimes, higher efficiencies, and lower financing costs, helped by clearer revenue models such as auctions, have all contributed to the sharp drop in LCOS. Ember has published a live calculator alongside the report, allowing users to estimate LCOS using their own assumptions.
Why this matters comes down to how solar is actually used. Most solar power is generated during the day, so only a portion needs to be stored to make it dispatchable. Ember estimates that if half of daytime solar generation is shifted to nighttime, the $65/MWh storage cost adds about $33/MWh to the cost of solar electricity.
With the global average price of solar at $43/MWh in 2024, adding storage would bring the total cost to about $76/MWh, delivering power in a way that better matches real demand.
As Ember global electricity analyst Kostantsa Rangelova put it, after a 40% drop in battery equipment costs in 2024, the industry is now on track for another major fall in 2025. The economics of battery storage, she said, are “unrecognizable,” and the industry is still adjusting to this new reality.
“Solar is no longer just cheap daytime electricity; now it’s anytime dispatchable electricity. This is a game-changer for countries with fast-growing demand and strong solar resources,” Rangelova added.
Together, solar and battery storage are increasingly emerging as a scalable, secure, and affordable foundation for future power systems.

Nissan is reviving the Xterra, the rugged SUV that once attracted a cult-like following, but this time it will be “electrified.”
The Nissan Xterra will be electrified, but by how much?
Earlier this year, Nissan offered a sneak peek of its upcoming lineup in a shadowy image previewing several new vehicles.
Alongside the new 2026 LEAF, a plug-in hybrid Rogue, updated Pathfinder, and Sentra, Nissan teased a new electric “adventure-focused SUV,” which we later learned will be badged the Xterra.
The rugged electric SUV appeared to have a more upright, boxy stance than the original model. The previous Xterra attracted a cult-like following as a cheaper off-road alternative to the Toyota 4Runner, Ford Bronco, and Jeep Wrangler.
However, Nissan discontinued it after the 2015 model year as buyers opted for more efficient options like the Honda CR-V and Toyota RAV4.
The new Xterra, but this time “it will have to have electrification,” according to Nissan Americas chief planning officer, Ponz Pandikuthira.
Pandikuthira told MotorTrend that the next-gen Xterra “cannot be ICE only,” but just how electrified it will be remains up in the air. “Is that an EREV? Is that a parallel hybrid system? Is that a plug-in system? That’s not defined yet. That’s all being actively studied right now,” he explained.
Nissan plans to launch a series of new extended-range hybrid (EREV) vehicles based on its e-Power system. The e-Power system uses a gas-powered engine connected to a generator.
The generator feeds energy to the inverter, which charges the battery and electric motor. Since the ICE only charges the battery and does not drive the wheels, it benefits from the instant torque and smooth drive of an EV.
However, it’s still powered by a gas engine at the end of the day. The 2027 Nissan Rogue will be the first e-Power vehicle in the US.
The Xterra could also arrive as a plug-in hybrid (PHEV) similar to the 2026 Nissan Rogue. The 2026 Rogue will be Nissan’s first PHEV for the US and is expected to be a key part of its comeback plans.
It will go on sale in early 2026 with an EPA-estimated 36 miles of electric driving range. Combined with the gas engine, the hybrid powertrain provides up to 420 miles of EPA-estimated driving range.
The electrified Xterra will share a body-on-frame platform with the Pathfinder and Frontier, with a V-6 engine, all-wheel drive (AWD), and space for bigger batteries.
According to Pandikuthira, the V-6 will give it an edge over the competition, while the hybrid powertrain will improve efficiency.
The “electrified” Xterra will be built at Nissan’s Canton, Mississippi, plant, starting in 2028. The following year, a luxury Infiniti electric SUV, based on the Vision QXe concept, will join it.
Electrek’s Take
While Nissan is launching new PHEVs, hybrids, and EREVs, it has already pulled one electric SUV, the Ariya, from its US lineup.
For now, the only fully electric vehicle Nissan offers in the US is the 2026 LEAF. Although it was once viewed as a leader in the shift to EVs with the initial LEAF launching in 2010, Nissan has quickly fallen behind and is now scrambling to catch up.
Nissan hopes to plug the gap with a series of gas-power hybrids over the next few years until new all-electric vehicles begin rolling out in 2028.
Even with less efficient hybrid tech, Nissan is still late to the game and will need to keep pace with Toyota, Honda, Ford, Stellantis, and others betting on hybrids in the US.
