Sea-based trials of a wave energy converter weighing 50 metric tons have produced “highly encouraging results,” according to the company behind its development.

On Tuesday, Scotland-based AWS Ocean Energy said the average amount of power its device was able to capture “during a period of moderate wave conditions” came to more than 10 kilowatts, while it also recorded peaks of 80 kW.

In addition, AWS said its Waveswing was able to operate in more challenging conditions, including Force 10 gales.

The piece of kit — which has been described as a “submerged wave power buoy” — has a diameter of 4 meters and stands 7 meters tall.

The Waveswing, AWS Ocean Energy says, “reacts to changes in sub-sea water pressure caused by passing waves and converts the resulting motion to electricity via a direct-drive generator.”

Compared to more established renewable technologies, the 16 kilowatt Waveswing is small. Firms like Denmark’s Vestas, for instance, are working on 15 megawatt wind turbines.

This phase of testing is set to wrap up before the end of this year, with more tests set to be carried out in 2023.

In terms of real-world applications, AWS Ocean Energy CEO Simon Grey said the Waveswing had features that made it “ideal for remote power applications such as powering subsea oilfield assets and oceanographic monitoring.”

Grey later added that the firm also expected to “develop platforms hosting up to twenty 500 kW units with a potential capacity of 10 MW per platform.”

The sea trials are taking place at a European Marine Energy Centre testing site in the sheltered waters of Scapa Flow, Orkney.

An archipelago, Orkney is located north of the Scottish mainland. EMEC, which is based there, has become a major hub for the development of wave and tidal power since its inception in 2003.

Neil Kermode, who is EMEC’s managing director, said it had been “great to see the Waveswing deploy, survive and operate at our test site this year.”

“We know there are epic amounts of energy in the seas around the UK and indeed the world,” Kermode went on to add. “It is really rewarding to see a Scottish company make such progress in harvesting this truly sustainable energy.”

More from CNBC Climate:

While there is excitement about the potential of marine energy, the footprint of wave and tidal stream projects remains very small compared to other renewables.

In data released in March 2022, Ocean Energy Europe said 2.2 megawatts of tidal stream capacity was installed in Europe last year, compared to just 260 kilowatts in 2020.

For wave energy, 681 kW was installed, which OEE said was a threefold increase. Globally, 1.38 MW of wave energy came online in 2021, while 3.12 MW of tidal stream capacity was installed.

By way of comparison, Europe installed 17.4 gigawatts of wind power capacity in 2021, according to figures from industry body WindEurope.

The first giant 15 MW turbine is up at Germany’s largest offshore wind farm

The first giant 15 MW turbine is up at Germany’s largest offshore wind farm

Germany’s largest offshore wind farm under construction, EnBW’s He Dreiht, just hit a big milestone: The first enormous turbine is now up in the North Sea.

He Dreiht – which means “it spins” in Low German – is using Vestas’s massive 15 megawatt (MW) turbines, the first project in the world to install them. Just one spin of one of the rotors can generate enough electricity to power four households for an entire day.

When it’s finished, He Dreiht will have 64 mega turbines cranking out 960 megawatts (MW) of clean power – enough to supply around 1.1 million homes. And it’s being built without any government subsidies.

EnBW, one of Germany’s major energy companies, has been working in offshore wind for more than 15 years, but He Dreiht is their biggest project yet. “It will play a key role in helping us to significantly grow our renewable energy output from 6.6 GW to over 10 GW by 2030,” said Michael Class, who heads up EnBW’s generation portfolio development.

The project is a win for Vestas, too. “With the installation of the first V236-15.0 MW, we have reached an important milestone for both the He Dreiht project and our offshore ramp-up, which helps Germany build a more secure, affordable, and sustainable energy system,” said Nils de Baar, president of Vestas Northern & Central Europe.

He Dreiht is located about 85 kilometers (53 miles) northwest of Borkum and 110 kilometers (68 miles) west of Helgoland. At peak times, more than 500 workers will be out at sea building the farm, using a fleet of more than 60 ships. EnBW’s offshore team in Hamburg is running the show.

The installation process is a major operation. The 64 foundations were already set in the seabed last year. Parts for the turbines are loaded onto the installation vessel Wind Orca in Esbjerg, Denmark, and shipped out in a 12-hour journey to the construction site. From there, the turbines are lifted into place. Meanwhile, crews are also working on internal wind farm cabling.

A partner consortium made up of Allianz Capital Partners, AIP, and Norges Bank Investment Management owns 49.9% of the shares in He Dreiht.

Tesla gives update on Tesla Semi factory, says on track for volume production in 2026

Tesla gives update on Tesla Semi factory, says on track for volume production in 2026

Tesla has released a quick update about its Tesla Semi factory in Nevada. It says that it is on track for volume production of the electric semi truck in 2026.

The Tesla Semi was first scheduled to go into production in 2019, but it has faced numerous delays.

Now, it appears that there is finally some momentum to bring it to volume production.

For the last two years, Tesla has been working to build a new factory next to Gigafactory Nevada, where it builds the battery packs and drive units for most of its electric vehicles built in North America.

Today, Tesla released a “progress update on the factory, confirming that it finished building and it’s now working on deploying the production lines:

Tesla had previously mentioned aiming for volume production by 2025, but it is now only talking about starting production toward the end of the year and ramping up next year.

The automaker reiterated its planned production capacity of 50,000 units.

We recently reported that an early Tesla Semi customer, Ryder, stated that the electric truck program is experiencing more delays and a price increase described as “dramatic.”

They now expect to take deliveries of their first trucks later in 2026 and said that the price has increased “dramatically,” leading them to scale back their pilot program from 42 to 18 Tesla Semi trucks.

When originally unveiling the Tesla Semi in 2017, the automaker mentioned prices of $150,000 for a 300-mile range truck and $180,000 for the 500-mile version. Tesla also took orders for a “Founder’s Series Semi” at $200,000.

However, Tesla didn’t update the prices when launching the “production version” of the truck in late 2022. Price increases have been speculated, but the company has never confirmed them.

Vietnamese solar giant Boviet opens first US factory in North Carolina

Vietnamese solar panel maker Boviet Solar just opened the doors to its first US factory — a huge new PV module plant in Greenville, North Carolina.

The company dropped $294 million into the state-of-the-art facility, which will pump out Boviet’s Gamma Series monofacial and Vega Series bifacial solar panels. They’re using advanced PERC and N-Type solar cell tech, which basically means these panels are built to deliver higher efficiency and better performance across residential, commercial, industrial, and utility-scale projects.

The Greenville factory’s first phase is now online with an annual PV module output capacity of 2 gigawatts (GW). For Phase 2, which is scheduled to come online in the second half of 2026, Boviet will invest another $100 million to add 600,000 square feet and ramp up to another 2 GW. It will make high-efficiency solar cells.

Once both phases are complete, Boviet’s campus will cover more than 1 million square feet of manufacturing and R&D space. It’s one of the biggest clean energy manufacturing projects North Carolina has ever seen.

The jobs impact is significant, too. The first phase will create 460 skilled local jobs. Phase 2 is expected to add another 908, bringing the total to over 1,300 direct jobs, plus nearly 2,000 more indirect jobs across the region. That’s good news for Pitt County’s economy, real estate market, and workforce training programs.

“This facility is not just creating jobs, but creating opportunity, innovation, and a stronger foundation for eastern North Carolina,” said Senator Kandie Smith. Governor Josh Stein added that Boviet Solar’s move shows how North Carolina is leading the way in clean energy growth.
