A project to build a facility described as “the world’s largest offshore wind farm” took a big step forward this month by producing its first power.

Located in the North Sea, over 130 kilometers off England’s northeast coast, the Dogger Bank Wind Farm still has some way to go before it’s fully operational, but the installation and powering up of its first turbine is a major feat in itself.

That’s because GE Vernova’s Haliade-X turbines stand 260 meters tall — that’s higher than San Francisco’s Golden Gate Bridge — and have blades measuring 107 meters.

Turbine installation at Dogger Bank has required a huge amount of planning and preparation, with the Voltaire — a specialist vessel designed and built by the family-owned Jan De Nul Group — playing a key role.

With a lifting capacity of 3,200 metric tons, the Voltaire — named after the 18th-century French philosopher — will have installed a total of 277 Haliade-X turbines when its work is complete.

Described by Dogger Bank as the “largest offshore jack-up installation vessel ever built,” in many ways, it’s the pinnacle of an extensive supply chain involving numerous businesses and stakeholders.

The logistics are complex and multi-layered, with water depth a particular issue.

The sea in the Dogger Bank Offshore Development Zone is up to 63 meters deep, meaning the Voltaire’s ability to work in deeper waters is crucial. 

This is where its four legs come into play.

According to Jan De Nul, the legs of the Voltaire — which was built at the COSCO Shipping Shipyard in China — enable it to lift itself above the water’s surface.

With each leg measuring roughly 130 meters in length, they highlight the scale of equipment required to install huge offshore wind turbines like GE’s Haliade-X.

In an online Q&A before installations at Dogger Bank began, Jan De Nul’s Rutger Standaert spoke of their importance. “Thanks to those legs, the Voltaire can effectively operate at a water depth of 80 meters,” Standaert, who is manager of vessel construction at the business, said.

He noted that the Voltaire’s capabilities would enable installations further out to sea, allowing it to play a key role in the emerging floating offshore wind sector.

“Off the Scottish coast, for example, expensive floating windfarms are often the only way to tap into offshore wind,” he said. “The water is too deep for fixed windfarms, but the Voltaire can offer new opportunities.”

Thinking big

Once completed, the Dogger Bank Wind Farm will have a total capacity of 3.6 gigawatts (GW) and be able to power as many as six million homes per year, according to its developers.

Work on the project is taking place over three phases: Dogger Bank A, B, and C. A fourth phase of the wind farm known as Dogger Bank D has also been proposed, and would increase its capacity even further.

Søren Lassen is head of offshore wind research at Wood Mackenzie, a research and consultancy group. He described Dogger Bank as “a huge project, especially if you combine the three phases.”

“It is a project that requires a lot of preparation,” he told CNBC. “There’s the logistics in terms of having the vessels to do the installation … and then of course, you also have the logistics in terms of getting the components to the marshaling port.”

Both of these aspects were being made “a lot more complicated” by the use of next-generation turbines and a next-generation installation vessel, Lassen said.

“You have … a lot of innovation that goes into this. And not only do you need a new vessel or new components, you also need new factories to build those components.”

As such, a slew of upgrades and adjustments were needed to “reverberate throughout the entire value chain” for operations to run smoothly, he added.

Bigger turbines, bigger challenges?

Thanks to their sheer size, larger turbine designs have created a specific set of needs for the offshore wind sector and sites like the Dogger Bank Wind Farm.

“From cranes to vessels, we use a number of specially designed pieces of equipment to transport the Haliade-X turbines that will be used in this project,” a spokesperson for GE Offshore Wind said in a statement sent to CNBC.

Wood Mackenzie’s Lassen stressed the importance of having dedicated transportation vessels, noting that the towers of turbines need to be broken into three or four sections in order to fit on board.  

Massive blades represent the biggest challenge, he said, as they have to be laid flat. “And that just means that you need a very, very long transportation vessel, [and] that you need to stack them up accordingly.”

Meanwhile, delays or bottlenecks can have far-reaching — and expensive — consequences.

Lassen cited the example of blades not being delivered on time, which leads to vessels having to “go away and then come back half a year later to do the installation. This is very costly, of course.”

And delays also lead to lost revenue.

“These projects are going out [and] generating a lot of power from the day that they’re being installed, pretty much,” Lassen added.

“So any delays [and] you’re also losing a lot of revenue, especially right now when the power prices are really, really high.”

The bigger picture

Offshore wind farms are set to play a significant role in reducing emissions and hitting net zero goals in the years ahead — but a supply chain that’s well-run and reliable will be key to the industry’s success.

This is set to cost serious money. According to Wood Mackenzie, a base case of 30 GW of installations per year by 2030 — excluding China — will require investment of around $27 billion by 2026 to build out supply chains.

“The supply chain needs to invest,” Lassen said, adding that it also needed capital, certainty and concrete, firm orders. However, cost pressures mean there is currently uncertainty over projects planned for 2025, 2026 and 2027.

“Any delays to these projects takes away volume from the supply chain, and the supply chain needs that volume to convert it into revenue to build new factories,” Lassen explained.

It is crucial that projects planned for the next few years go ahead, he added. “That helps the underlying supply chain ramp up so they can build the capacity [for] ’27, ’28, ’29 and well into the 2030s as well.”

Clear skies ahead – Delta partners with Maeve on M80 hybrid regional aircraft

Delta Air Lines is teaming up with Dutch aviation startup Maeve Aerospace to take its idea for a more advanced, fuel-sipping hybrid-electric aircraft powertrain from the drawing board and into regional commercial service.

Delta Air Lines announced a new partnership with Maeve Aerospace meant to accelerate certification and deployment of the startup’s next-generation hybrid-electric regional aircraft – a move that could reduce the company’s fuel consumption on those routes by up to 40% compared to ICE-only assets.

“Delta is proud to collaborate with Maeve to help shape the next chapter of regional aviation and accelerate progress toward a more sustainable future of flight,” said Kristen Bojko, Vice President of Fleet at Delta Air Lines. “As we work toward the next generation of aircraft, we look to partners like Maeve who embody the bold, forward-thinking innovation we champion at Delta – solutions that advance aircraft design, enhance operational efficiency, elevate employee and customer experiences, and cut emissions. While driving toward transformative technologies that strengthen our network and redefine regional air travel remains a key priority, we’re equally focused on safety and a more sustainable future of flight.”

The collaboration positions Delta among a growing list of carriers investing in lower-carbon emission aviation tech as regulators, passengers, and activist investors alike push for cleaner operations.

Maeve introduced its M80 hybrid-electric, 80-seater aircraft in November of 2023 as a sustainable, cost-effective aircraft designed to satisfy the operational needs of the majority of regional operators and airports.

As designed, the M80 promises an operating range of more than 900 miles (~1,500 km) with 40% higher fuel efficiency than conventional aircraft. Similar in concept to the way Toyota’s Prius uses its electric motors to accelerate and cruises on a small ICE engine, the Maeve’s hybrid engine architecture provides additional electric power assistance at low altitude, high-drag flight.

The M80’s electric motors can also be used during taxiing operations on the ground to reduce surface-level carbon emissions while also supporting a more efficient integration of more electric aircraft systems. Two facets of the aircraft’s designs that are specifically called out by Delta’s press material as being of extreme interest to the commercial carrier.

“It’s a privilege to have Delta as a partner in the development of groundbreaking technologies and processes,” shared Martin Nuesseler, Chief Technology Officer at Maeve Aerospace. “Their expertise in fleet innovation and commitment to aviation sustainability is unmatched, and we’re proud to work together to tailor the MAEVE Jet for the US market.”

Hear me out: instead of faster chargers, we should lobby for SLOWER gas pumps

Hear me out: instead of faster chargers, we should lobby for SLOWER gas pumps

Utilities, state governments, and private developers are racing to roll out faster, more powerful EV chargers. At the same time, automakers and tech giants across the globe are pouring billions into R&D to develop batteries that can take ever-higher levels of power. But what if there’s a better, easier, cheaper, and more effective way to cut emissions?

What if, instead of faster chargers, we pushed for SLOWER gas pumps?

I want to start this conversation by pointing out that there’s a precedent for this idea. Back in 1993, the Environmental Protection Agency (EPA) finalized a rule that limited the rate that gas service stations could pump fuel to a maximum of 10 gallons per minute (gpm), with the stated goals of reducing evaporative emissions and promoting safety by ensuring the integrity of the nation’s refueling infrastructure.

Officially dubbed “61 FR 33033 – Regulation of Fuels and Fuel Additives: Controls Applicable to Gasoline Retailers and Wholesale Purchaser-Consumers; 10 Gallon Per Minute Fuel Dispensing Limit Requirement Implementation,” the rule was finalized in January of 1993 and went into effect in 1996. Now, almost thirty years later, I think it’s time to revisit 61 FR 33033 in a way that helps reduce emissions even more.

To zero.

The pitch


Gavin Newsom high-fives JB Pritzker; by ChatGPT.

The basic idea is this: instead of “just” asking for utility rate-payers and State or local governments to help cover the costs of rolling out an increasingly huge EV charging infrastructure that will never be big enough to convince the red hats it’s ready, anyway, we focus our lobbying efforts on slower gas pumps in blue states. Like, significantly slower gas pumps.

By reducing the maximum pumping speed from 10 gpm to 3 gpm, we could increase the minimum time to fill up a half-ton Ford F-150’s 36 gallon fuel tank (yes, really) from under four minutes to nearly twelve (12). Factor in the longer wait times ICE-vehicles would have to endure waiting in line to refuel, as well, and we’re talking about a 20-30 minute turnaround time to go from just 10% to a usable 80-or-90% fill.

Y’all see where I’m going with this?

Everybody wins


EV charging, via BP Pulse.

Way back in 2022, oil giant BP claimed that its BP Pulse electric vehicle chargers were “on the cusp” of being more profitable than its gas pumps. Now, three years and several technological leaps since, BP is investing billions to expand its EV charging infrastructure – and it doesn’t take a genius to realize that they’re expecting a positive ROI.

You don’t have to take my word for that, though. You can take big oil’s. “If I think about a tank of fuel versus a fast charge, we are nearing a place where the business fundamentals on the fast charge are better than they are on the (fossil) fuel,” BP head of customers and products, Emma Delaney, told Reuters.

Those fundamentals revolve around amenities. If you’re popping into a gas station for a three or four minute visit, you’re probably getting in and out as fast as you can. But if you’re there a bit longer? That’s a different story. You might visit the rest room, might buy a snack or order a coffee or suddenly remember you were supposed to pick up milk on your way home, even – and that stuff has a much higher margin for the gas station than the dino-juice, totaling 61.4% of all fuel station profits despite being a fraction of the overall revenue.

The other big winner, of course, is literally everyone. The forgotten costs of fossil fuels cost Americans billions in healthcare bills and environmental clean up each year, and untold trillions of dollars of military spending (to say nothing of the toll on three generations of American blood spilled in the Middle East to secure an affordable supply of oil).

With this plan, ICE-holes and Hemi zealots can continue to have their gas (if they decide it’s worth the wait, so be it). Meanwhile, the well-adjusted normals figure out real quick that it’s better, cheaper, and easier to charge at home.

The rest will take care of itself.

What do you guys think? Does this low-cost, high-impact idea to cut the time delta between refueling your gas car and recharging your EV have legs? What concerns do we need to address before we take it to Gavin and JB? Let us know, in the comments!

John Deere adds new, updated Gator GX and GX Crew electric UTVs for 2026

John Deere adds new, updated Gator GX and GX Crew electric UTVs for 2026

Just weeks after writing about John Deere’s tried-and-true Gator side-by-side and extolling the virtues of its two-plus decades of design stasis, the engineers at Deere have launched a pair of new, li-ion Gator models that offer all-day power to move people and things all over your property in true, go-anywhere Gator fashion.

John Deere is quick to point out that these new GX side-by-side utility vehicles are not golf carts. Fair enough – while they;re not quite in the same go-anywhere league as Deere’s TH 6×4 Gas or TE 4×2 Gators, the Gator GX and GX Crew offer more than enough capability to handle just about anything you’ll find on a typical campus, golf course, or job site.

To that end, the sturdy composite dump bed, comfortable and supportive high-back foam seats seem credible enough at first glance. And, if you give the new Deere UTVs a second glance, you’ll see a 367-L (13-cu ft) cargo box can haul more than 800 lbs. (~365 kg) of mulch, nursery plantings, building supplies, firewood, animal feed, or tools.

These are serious machines, in other words, ready to get down and do some serious work, but without the noise, vibration, and harmful exhaust emissions of gas.

“The Gator GX lineup offers property owners the opportunity to increase productivity around their properties with less noise, less maintenance and more versatility,” said John Deere Go To Market Manager Eric Halfman. “These utility vehicles are intuitive and durable while offering users the comfort, reliability and convenience they expect from a John Deere Gator.”

The key component in the new GX and GX Crew is the new, 5.4 kWh, 51.2V lithium-ion battery that sends power to a high-efficiency electric drive motor with responsive torque and smooth acceleration. An onboard charger allows for convenient charging anywhere with a standard, grounded 120 outlet, eliminating the need for handling fuel or trips to the gas station and fully charging the 5.4 kWh battery over night, with more than 8 hours of continuous operation on tap that’s extendable with clever use of the new Deere’s regenerative braking.

These new electric Gators are available in classic John Deere green or grey metallic, and start at $17,499 with a whole suite of available accessories to make upfitting a breeze. The company says they’ll be available for order at your local John Deere TriGreen dealer in Q1 of 2026.

Electrek’s Take


I imagine that applying the Gator name to a vehicle that I’d call a glorified golf cart makes me feel something similar to what the Mustang guys feel whenever they see a Mach-E drive past. As such, I’ll give myself the same advice I give them: the people who make the thing decide what makes it worthy of the name, not you.

As such, I’d better get used to it. The good news there, of course, is that it seems like Deere’s latest Gator is going to be more than good enough to win me over. Eventually.
