Luxury electric boatbuilder ALVA Yachts is back with its latest solar electric catamaran. The upcoming OCEAN ECO 78 will arrive as a mid-size marine vessel in ALVA’s current lineup and comes equipped with the solar and electric propulsion technology to reach a top speed of 14-15 knots (16-17 mph) at sea, plus plenty of battery capacity to go far – all backed by solar panels on its roof.
ALVA Yachts is a German company founded in 2020 by Mathias May and Holger Henn, evolving out of PICA yachts, which was originally founded back in 2013. In that time, ALVA’s predecessor launched over forty 20-30 foot sailing and electric powerboats.
As the brand looks to create the next generation of electric yachts, it remains quite aware of the issues facing marine electrification as well as its own hurdles in developing its zero emission technologies. Its current solution is a growing lineup of solar electric catamarans that are as luxurious as they are sustainable.
The past three years, ALVA Yachts has introduced a 50-foot cruiser, two electric sailboats in lengths of 72- and 82-feet, plus 60- and 90-foot all-electric yachts, including the OCEAN ECO 60, which debuted in 2022 and is now in production.
Today ALVA Yachts has introduced a new 78-foot solar electric catamaran that will fit nicely between the OCEAN ECO 60 and OCEAN ECO 90.

ALVA Yachts ‘launches’ its latest solar electric boat
The sustainable boatbuilder unveiled the OCEAN ECO 78 in a press release today – a multihull yachts that measures in at 23.7 meters, features a fully-electric drive system, and offers the ability to gain additional power from the Sun, even while navigating the sea.
The fully-electric version of the OCEAN ECO 78 is propelled by two 217 kW electric motors that are powered by massive battery capacity ranging between 280-490 kWh. The large roof of integrated solar panels allows for 26 kilowatt-peak (kWp), which ALVA Yachts states is best in class compared to the 78’s competitors.
By combining large battery capacity and solar integration, ALVA Yachts states the upcoming OCEAN ECO 78 will offer transatlantic range and “virtually unlimited autonomy” with the help of the Sun. From bow to stern, the solar electric catamaran is strengthened by 12-meter beams, another best in class design according to its makers. ALVA’s head of design Milan Henn spoke to the boatbuilder’s latest entry in responsible yachting:
The new OCEAN ECO 78 was created as the perfect addition to our existing range, and sits between the OCEAN ECO 60 and 90 models providing owners with a generous increase in size from the 60 but removing the need for crew on the 90. This new model offers everything the 60 does but on a larger scale.
Other features include twin bathing platforms for easy access to the water, a lower deck with seating for eight, an enclosed saloon, and galley complete with a full size fridge/freezer and island bar with stools. Moving to starboard, OCEAN ECO 78 owners can entertain at a large dining table for eight or at it’s L-shaped obervation area near the helm.
Accommodations include a master suite with a walk in wardrobe, a double guest cabin with ensuite, plus further guest spaces to the portside hull, including double and twin rooms with showers. Like all ALVA Yachts, customers can choose from one of five moods for their interior, including Mountain, Forest, Desert, Dune and Sea. We are awaiting additional details such as the yacht’s estimated range, pricing, and production timeline, but when the OCEAN ECO 78 does arrive, it looks to be another impressive entry in solar electric catamarans. Per ALVA Yachts:
ALVA Yachts is bringing yachting into a new era with electrified solar catamarans and sailing yachts that combine self-sufficient, long-range cruising capabilities and class-leading design, delivering the best boats for forward-thinking explorers.

The new John Deere Z370RS Electric ZTrak zero turn electric riding mower promises all the power and performance Deere’s customers have come to expect from its quiet, maintenance-free electric offerings – but with an all new twist: removable batteries.
The latest residential ZT electric mower from John Deere features a 42″ AccelDeep mower deck for broad, capable cuts through up to 1.25 acres of lawn per charge, which is about what you’d expect from the current generation of battery-powered Deeres – but this is where the new Z370RS Electric ZTrak comes into its own.
Flip the lid behind the comfortably padded yellow seat and you’ll be greeted by six (6!) 56V ARC Lithium batteries from electric outdoor brand EGO. Those removable batteries can be swapped out of the Z370RS for fresh ones in seconds, getting you back to work in less time than it takes to gravity pour a tank of gas.
When John Deere launched the first Z370R, Peter Johnson wrote that electrifying lawn equipment needs to be a priority, citing EPA data that showed gas-powered lawnmowers making up five percent of the total air pollution in the US (despite covering far less than 5% of the total miles driven on that gas). “Moreover,” he writes, “it takes about 800 million gallons of gasoline each year (with an additional 17 million gallons spilled) to fuel this equipment.”

Daimler Truck AG CEO Karin Rådström hopped on LinkedIn today and dropped some absolutely wild pro-hydrogen talking points, using words like “emotional” and “inspiring” while making some pretty heady claims about the viability and economics of hydrogen. The rant is doubly embarrassing for another reason: the company’s hydrogen trucks are more than 100 million miles behind Volvo’s electric semis.
UPDATE 22NOV2025: Daimler just delivered five new hydrogen semis for trials.
While it might be hard to imagine why a company as seemingly smart as Daimler Truck AG continues to invest in hydrogen when study after study has shut down its viability as a transport fuel, it makes sense when you consider that the Kuwait Investment Authority (KIA) holds approximately 5% of Daimler and parent company Mercedes’ shares.
That’s not a trivial stake. Indeed, 5% is enough to make KIA one of the few actors with both the access and the motivation to shape conversations about Daimler’s long-term technology bets, and as a major oil-producing country whose economy would undoubtedly take a hit if oil demand plummeted, any future fuel that’s measured molecules instead of electrons isn’t just a concept for the Kuwaiti economy: it’s a lifeline.
In that context, the push to make hydrogen seem like an attractive decarbonization option makes more sense. So, instead of giving Daimler’s hydrogen propaganda team yet another platform to try and convince people that hydrogen might make for a viable transport fuel eventually by giving five Mercedes-Benz GenH2 semi trucks to its customers at Hornbach, Reber Logistik, Teva Germany with its brand ratiopharm, Rhenus, and DHL Supply Chain, I’m just going to re-post Daimler CEO Karin Rådström’s comments from Hydrogen Week.
For some reason – posts about hydrogen always stir up emotions. I think hydrogen (not “instead of” but “in parallel to” electric) plays a role in the decarbonization of heavy duty transport in Europe for three reasons:
If we would go “electric only” we need to get the electric grid to a level where we can build enough charging stations for the 6 million trucks in Europe. It will take many years and be incredibly expensive. A hydrogen infrastructure in parallel will be less expensive and you don’t need a grid connection to build it, putting 2000 H2 stations in Europe is relatively easy.
Europe will rely on import of energy, and it could be transported into Europe from North Africa and Middle East as liquid hydrogen. Better to use that directly as fuel than to make electricity out of it.
Some use cases of our customers are better suited for fuel cells than electric trucks – the fuel cell truck will allow higher payload and longer ranges.
At European Hydrogen Week, I saw firsthand the energy and ambition behind Europe’s net-zero goals. It’s inspiring—but also a wake-up call. We’re not moving fast enough.
What we need:
Large-scale hydrogen production and transport to Europe
A robust refueling network that goes beyond AFIR
And real political support to make it happen – we need smart, efficient regulation that clears the path instead of adding hurdles.
To show what’s possible, we brought our Mercedes-Benz GenH2 to Brussels. From the end of 2026, we’ll deploy a small series of 100 fuel cell trucks to customers.
Let’s build the infrastructure, the momentum, and the partnerships to make zero-emission transport a reality. 🚛 and let’s try to avoid some of the mistakes that we see now while scaling up electric. And let’s stop the debate about “either or”. We need both.

At the risk of sounding “emotional,” Rådström’s claims that building a hydrogen infrastructure in parallel will be less expensive than building an electrical infrastructure, and that “you don’t need a grid connection to build it,” are objectively false.
Next, the claim that, “Europe will rely on import of energy, and it could be transported into Europe from North Africa and Middle East as liquid hydrogen” (emphasis mine), is similarly dubious – especially when faced with the fact that, in 2023, wind and solar already supplied about 27–30% of EU electricity.
Unless, of course, Mercedes’ solid-state batteries don’t work (and she would know more about that than I would, as a mere blogger).
Electrek’s Take
Via Mahle.
As you can imagine, the Karin Rådström post generated quite a few comments at the Electrek watercooler. “Insane to claim that building hydrogen stations would be cheaper than building chargers,” said one fellow writer. “I’m fine with hydrogen for long haul heavy duty, but lying to get us there is idiotic.”
Another comment I liked said, “(Rådström) says that chargers need to be on the grid – you already have a grid, and it’s everywhere!”
At the end of the day, I have to echo the words of one of Mercedes’ storied engineering partners and OEM suppliers, Mahle, whose Chairman, Arnd Franz, who that building out a hydrogen infrastructure won’t be possible without “blue” H made from fossil fuels as recently as last April, and maybe that’s what this is all about: fossil fuel vehicles are where Daimler makes its biggest profits (for now), and muddying the waters and playing up this idea that we’re in some sort of “messy middle” transition makes it just easy enough for a reluctant fleet manager to say, “maybe next time” when it comes to EVs.
We, and the planet, will suffer for such cowardice – but maybe that’s too much malicious intent to ascribe to Ms. Rådström. Maybe this is just a simple “Hanlon’s razor” scenario and there’s nothing much else to read into it.
Let us know what you think of Rådström’s pro-hydrogen comments, and whether or not Daimler’s shareholders should be concerned about the quality of the research behind their CEO’s public posts, in the comments section at the bottom of the page.

Audi embraced its future in China with the launch of a new Chinese market electric sub-brand called AUDI that ditched the iconic “four rings” logo in favor of four capital letters – but one thing this latest concept hasn’t ditched is the brand’s traditionally teutonic long-roof design language.
Co-developed with Audi’s Chinese production partner, SAIC, the all-new AUDI E SUV concept is based on the PPE (Premium Platform Electric) skateboard, and is only the second model introduced by the company’s domestic sub-brand — which was all-new itself just one year ago.
“The AUDI E SUV concept celebrates the new AUDI brand’s first anniversary following the E concept’s debut in Guangzhou (2024),” said Fermín Soneira, CEO of the Audi and SAIC cooperation, at the E SUV’s unveiling. “It showcases an unmistakable AUDI design language that gives the SUV a prestigious, progressive stance — with no compromise between sporty aesthetics and interior roominess or versatility. This concept embodies our vision for premium electric mobility by fusing Audi’s engineering heritage with digital innovation to fulfill our commitment in China.”
As a vehicle, the AUDI E SUV concept promises to handle “like an Audi,” and is powered by a pair of electric motors good for a combined 500 kW (~670 hp), good enough to get the big crossover from 0-100 km/h (62 mph) in about five seconds. Those efficient motors are fed electrons by a 109 kWh battery riding on AUDI’s 800V Advanced Digital Platform system architecture, and can allegedly add 320 km (~200 miles) of range in under 10 minutes at a high-powered DC fast charging station.
