In less than two weeks, Chinese wind turbine maker Mingyang has stolen the title of “world’s largest offshore wind turbine” from CSSC Haizhuang.

Another mammoth Chinese offshore wind turbine

Offshore wind turbines just keep getting bigger: Mingyang Smart Energy has unveiled the MySE 18.X-28X, and it’s bumped CSSC Haizhuang’s H260-18MW out of the top spot.

The MySE 18.X-28X features a rotor diameter of more than 919 feet (280 meters) and 459-foot (140-meter) blades. The turbine has a swept area of 711,000 square feet (66,052 square meters) – that’s equivalent to the area of nine football fields.

Under an annual average wind speed of 8.5 miles per second, each turbine can generate 80 GWh of electricity per year, and that’s enough to power 96,000 households, while reducing carbon dioxide emissions by 66,000 tonnes, according to Mingyang.

Compare that to CSSC Haizhuang’s H260-18MW’s specs:

The H260-18MW will have a rotor diameter of 853 feet (260 meters). To put that in perspective, that rotor diameter is as long as the height of the Haliade-X, which has a rotor diameter of 722 feet (220 meters). The 18 MW turbine will have 420-feet-long (128-meter-long) blades with a swept area of 570,487 square feet (53,000 square meters).

Mingyang says its massive turbine will be able to operate reliably in “the most extreme ocean conditions such as a level-17 typhoon with wind speeds >56.1 m/s.”

The company doesn’t indicate a timeline for production on its announcement.

Why do offshore wind turbines keep getting bigger?

To put it succinctly, efficiency and cost cutting. Mingyang explained on LinkedIn:

When compared to the installation of 13 MW models, the higher output of the MySE18.X-28X would save 18 units required for a 1 GW wind farm, shaving off construction costs by $120,000-150,000 per megawatt.

Increasing the swept area of a wind turbine increases power output, and it costs money to put each offshore wind turbine into the seabed. So if you put a more powerful turbine in, then you’re going to need to install fewer wind turbines. It brings down the cost of installation, and eventually the cost of energy that the offshore wind turbines generate.

But it remains to be seen whether increasing the size of these giant wind turbines will throw up logistical and supply chain challenges.

Oil giant Saudi Aramco posts 15% drop in third-quarter profit but maintains dividend

Oil giant Saudi Aramco posts 15% drop in third-quarter profit but maintains dividend

Saudi state oil giant Aramco reported a 15.4% drop in net profit in the third-quarter on the back of “lower crude oil prices and weakening refining margins,” but maintained a 31.05 billion dividend.

The company reported net income of $27.56 billion in the July-September period, topping a company-provided estimate of $26.9 billion. The print is also a 5% drop from the previous quarter, which came in at $29.1 billion, as lower global oil prices, weaker demand and prolonged OPEC+ production cuts led by Saudi Arabia continue to impact crude prices.

The average selling price of oil for the second quarter of 2024 stood at $85 per barrel, but dropped to $78.7 per barrel during the third quarter, according to Saudi-based bank Al Rajhi capital, as non-OPEC supply volumes grew.

The oil firm said its year-on-year decline was partly offset by a “reduction in selling, administrative and general expenses primarily driven by a gain from derivative instruments, and a decrease in production royalties largely reflecting lower crude oil prices and a lower average effective royalty rate compared to the same quarter last year.”

Aramco’s dividend includes a base payout of $20.3 billion and an atypical performance-linked one of $10.8 billion. The Saudi government and the kingdom’s sovereign wealth vehicle, the Public Investment Fund, are the main beneficiaries of the dividend, holding stakes of roughly 81.5% and 16% in the company.

The remaining shareholding trades freely on Saudi Arabia’s Tadāwul stock exchange, with the company having finalized its second public share offering back in June.

Aramco’s earnings before Interest and Taxes (EBIT) came in at $51.45 billion in the third quarter, down 17% year-on-year. Aramco’s capital expenditure guidance was brought up 20% to $13.23 billion.

The company was trading at 27.45 riyals following the announcement, down 0.18% on the previous day.

The earnings align with a broader trend across oil majors, whose third-quarter profits have also suffered from declines in crude prices and refining margins. Aramco said it achieved average realized crude price of $79.3 per barrel in the third quarter, compared with $89.3 per barrel in the same period of last year.

Saudi Arabia, the world’s largest crude exporter who produces roughly 9 million barrels per day of crude at present, serves as the de facto leader of the OPEC+ oil producers’ alliance, a subset of whom agreed over the weekend to delay a planned December output hike by one month.

OPEC chief says delayed December output hike is 'nothing unusual'

“Aramco delivered robust net income and generated strong free cash flow during the third quarter, despite a lower oil price environment,” CEO Amin Nasser said in a statement. “We also progressed our upstream developments, strengthened our downstream value chain, and advanced our new energies program as we continue to invest through cycles.”

The revenues will be a boon to the Saudi economy, which is currently undergoing a diversification process under Crown Prince Mohammed bin Salman’s legacy Vision 2030 scheme spanning a slew of high-cost infrastructure “gigaprojects.”

Earlier this year, Saudi Arabia’s Ministry of Finance cut the kingdom’s growth forecast to 0.8% in 2024, in a steep decline from a previous projection of 4.4%, and raised the outlook for the national budgetary shortfall to roughly 2.9% of GDP, from a prior indication of 1.9%.

This 'supercharger on wheels' brings fast charging to you [update]

Mobile car care company Yoshi Mobility launched a DC fast charging EV mobile unit that it likens to “a supercharger on wheels.”

November 4, 2024 update: Yoshi Mobility will only be charging EVs on the side of the road now – it announced today that it’s selling its fleet fueling operation to EZFill Holdings (Nasdaq: EZFL).

It was originally founded as a direct-to-consumer, mobile fueling business in 2016, but now it’s going to focus on mobile EV charging, virtual vehicle inspections for partners like Uber and Turo, and onsite preventative maintenance.

Bryan Frist, Yoshi Mobility’s CEO & cofounder, said, “By spinning off our fuel business and focusing all of our energy on solving hair-on-fire problems that fleet owners face, we are meeting the changing needs of enterprise customers while making the future of transportation safer, cleaner, and more sustainable.”

May 22, 2024: Yoshi Mobility saw that its existing customers needed mobile EV charging in places where infrastructure has yet to be installed, so the Nashville-based company decided to bring the mountain to Moses.

“We recognized a demand among our customers for convenient daily charging, reliable private charging networks, and proper charging infrastructure to support their fleet vehicles as they transition to electric,” said Dan Hunter, Yoshi Mobility’s chief EV officer and cofounder.

The company says its 240 kW mobile DC fast charger, which can turn “any EV” into a mobile charging unit, is the first fully electric mobile charger available. It can provide multiple charges in a single trip but doesn’t detail how they charge the DC fast charger or who manufactured it. (I asked for more details, and they replied that they won’t disclose client names or the manufacturer of its DC fast charger yet.)

Yoshi is launching its mobile charger on two GM BrightDrop Zevo 600s and will introduce additional vehicles throughout 2024. It aims for full commercialization by Q1 2025. (I wonder if the Zevo 600 ever charges itself? Yes, I asked that too.)

Yoshi Mobility says it’s already deployed its EV charging solutions to service “major OEMs, autonomous vehicle companies, and rideshare operators” across the US. Its initial customers are made up of large EV operators managing “hundreds” of light-duty vehicles requiring up to 1 megawatt of energy per day that don’t yet have grid-connected EV chargers. I’ve asked Yoshi for details of who it’s working with, and will update if they share that info.

The company says pricing is based on location and enterprise charging needs. Once under contract for service, the service will be deployed to US-based customers within 10 days.

To date, Yoshi Mobility has raised more than $60 million, with investments from GM Ventures, Bridgestone, ExxonMobil, and Y-Combinator in Silicon Valley.
