Everybody is talking about a new EU clean power project that pairs floating solar with offshore wind turbines, but they’re missing half the story. Wave energy is also part of the project. The wave part is not getting much attention, probably because wave-to-electricity conversion has fallen behind wind and solar in the renewable energy race. Nevertheless, if all goes according to plan, the waters of the EU will be peppered with wave conversion devices as well as floating solar panels.

More Offshore Solar & Wind Turbines With Wave Energy, Too

The EU project is tackling the problem of how to make room for new offshore energy industries in busy coastal waters. Finding sites for new offshore wind farms can be a tough row to hoe, as offshore wind fans in the US can testify.

The new project is called EU-SCORES for “European SCalable Offshore Renewable Energy Sources.” The idea is to pair wind turbines with other clean power systems, with the aim of reducing the overall footprint of marine energy development.

EU-SCORES comes under the umbrella of the Dutch Marine Energy Centre, which will assess two sites for hybrid marine energy systems. One is a solar-plus-wind site in Belgium, which has been getting a lot of attention, and rightfully so. Floating solar is a relatively new idea that has been catching on fast for application to inland water bodies including reservoirs as well as natural lakes and ponds. The idea of setting solar panels afloat in the open sea poses new technology challenges.

In that regard, EU-SCORES shares some similarities with the CrossWind offshore wind project under way in the Netherlands, which is also on track to receive floating solar panels.

However, EU-SCORES seems to be taking a much more aggressive approach to hybridizing offshore wind farms. As DMEC describes it, the “full-scale demonstrations are intended to prove how the increased power output and capacity installed per km2 will reduce the amount of marine space needed, thereby leaving more space for aquaculture, fisheries, shipping routes and environmentally protected zones.”

“Additional benefits achieved by co-using critical electrical infrastructures and exploring advanced operation and maintenance methodologies supported by innovative autonomous systems should lower the costs per MWh,” DMEC adds.

Wave Energy: It’s All About Co-Location, Location, Location

Where were we? Oh right, wave energy. If you caught that thing about co-using, that’s a critical issue for wave energy stakeholders. Translating the infinite, 24/7 motion of waves into electricity is a tantalizing goal, but one of the factors holding back the wave energy field is the relatively high cost of shunting clean kilowatts from seagoing wave energy generators over to coastal communities.

Back in 2014, the United Nations’ International Renewable Energy Agency took a look at the wave energy field and recorded 100 projects around the world, all of which were still in the pilot and demonstration phases. The early-stage nature of the technology made it difficult to project future costs for commercial-level projects. However, IRENA did come up with the figure of 22% for the proportion of lifetime costs that could be ascribed to power take-off systems.

IRENA also estimated that installation, operation, and maintenance, and mooring would account for another 41% of lifetime costs for wave energy projects. Co-location with offshore wind turbines would presumably shave away some of those costs as well.

About Those Locations…

Another kind of challenge for the wave energy industry is that the recovery potential varies considerably from one place to another. The one-size-fits-all nature of wind turbines and solar panels does not apply as much to the wave energy field, and that has slowed the development of more mature, efficient supply chains.

In 2016, the US Department of Energy’s National Renewable Energy Laboratory looked at the problem and noted that “wave energy technology is still an emerging form of renewable energy for which large-scale grid-connected project costs are currently poorly defined.”

“Ideally, device designers would like to know the resource conditions at economical project sites so they can optimize device designs. On the other hand, project developers need detailed device cost data to identify sites where projects are economical. That is, device design and siting are, to some extent, a coupled problem,” the lab continued.

A New Burst Of Energy For Wave Energy

Regardless of the challenges, wave energy fans have persisted, and it looks like all that hard work is about to pay off. The wave energy harvesting end of the EU-SCORES project is being attached to an offshore wind farm in Portugal, using buoy-type wave harvesting devices developed by the Swedish company CorPower Ocean, as the firm’s Commercial Director Kevin Rebenius is happy to explain.

“We see great value in showcasing the highly consistent and complementary power profile of wave energy, and how this can be combined with wind and solar to deliver a more stable and predictable electricity system based purely on renewables,” Rebenius said.

CorPower Ocean’s contribution to the wave energy field is a pumping system modeled on natural pumps such as those found in the human heart.

According to CorPower, its device can produce 5 times more electricity per ton than other wave energy harvesters, partly by enabling superior performance during calm periods and partly by maintaining performance during storms. Here, let’s have them explain.

“CorPower WECs can harvest the same amount of Annual Energy from a buoy with 1/10 volume compared to conventional point absorber WEC. 1. As comparison, a 300kW CorPower WEC has a diameter of 9m and weighs 60 tonnes. Getting large amounts of electricity from a small device significantly reduces CAPEX. The compact lightweight devices are also less costly to transport, install and service, bringing down OPEX.”

There Had To Be A Green Hydrogen Angle In There Somewhere…

CorPower is aiming to make the case for commercial viability by 2024. Meeting that goal will also provide a boost to other companies involved with EU-SCORES. For those of you keeping score at home, that includes the offshore floating solar company Oceans of Energy along with the familiar names of RWE, EDP, ENEL Green Power, and Simply Blue Group.

EU-SCORES could also add another notch in the belt of green hydrogen fans. CorPower, for one, is already making the pitch.

“The multi-source demonstrations in EU-SCORES will showcase the benefits of more consistent power output harnessing complementary power sources including waves, wind and sun, creating a more resilient and stable power system, higher capacity factors and a lower total cost of the power system. These aspects will also improve the business case for green hydrogen production, by allowing electrolysers to run at higher utilisation,” CorPower enthuses.

For those of you new to the topic, electrolysis refers to electrical systems that pop hydrogen gas out of water. That doesn’t make any sense at all from a climate action perspective if the electricity is sourced from fossil energy, but sub in renewables and the whole picture shifts.

The renewable energy angle is also a rather significant improvement over the current state of affairs, in which the global supply of hydrogen is sourced primarily from natural gas and coal. With the addition of seagoing solar panels and wave energy devices envisioned by EU-SCORES, it looks like end of the fossil grip on the global hydrogen economy is in sight.

What are these hidden vehicles in Rivian’s shareholder letter?

What are these hidden vehicles in Rivian's shareholder letter?

On top of Rivian’s big VW partnership news today, we also got a look at what some of Rivian’s future plans might include – including some vehicles that we haven’t heard anything about before.

To recap the news, VW will invest up to $5 billion into Rivian and form a joint venture giving VW access to much of Rivian’s electrical and electronic architecture expertise. This will help Rivian with much-needed liquidity as it tries to get costs down and start generating cash flow from vehicle sales, and will help VW with the software issues it has been having in ramping up its EV projects.

To explain the news, Rivian posted a shareholder letter on its website, which is mostly filled with the basic financial details that we saw earlier in press releases.

But it also includes a graphic demonstrating the scalability of Rivian’s software across its platforms, meant to show how Rivian is unifying and simplifying its vehicle control software.

And that graphic has something very interesting – some hidden vehicles that we haven’t heard anything about yet. Have a look:

The obvious ones here are the already-released vehicles, Rivian’s RCV, R1T and R1S. The R1T and R1S are then repeated in column 2, in reference to the newly-released “Gen 2” architecture. This architecture led to a big upgrade in Rivian’s EVs for this model year, cutting lots of cost and complexity.

Then, in column 3, we have the R2 and R3 which Rivian unveiled in March. These will both be built on an architecture Rivian is calling “MSP.”

But despite that we’ve seen these next-gen R1 and MSP vehicles, both columns 2 and 3 have placeholder vehicles under covers.

While these are definitely just placeholder images and could be anything, they are notably a different size/shape than each other, suggesting that the unreleased gen 2 vehicle will be larger than the MSP vehicle.

The gen 2 vehicle could be an upgraded RCV, with more simplified electronics for cost-cutting, but the silhouette doesn’t look right. However, that might be an attempt by Rivian to obfuscate the car’s form, as a van silhouette would be quite obvious.

The unreleased gen 3 vehicle, then, does look lower and smaller than the gen 2. It could indeed be the R3X, but we’ve already seen that one, so it wouldn’t make a lot of sense to put it back under a cover. That said, Rivian was a little more secretive about showing us the interior of the R3X, as compared to the amount of info it gave us about the R2, so it could be the R3X… but wouldn’t it be more fun if it wasn’t?

For one thing, it could potentially be an R2T, a more affordable and smaller truck. While we knew the R2 would come in SUV format, many assumed that Rivian might mention an R2 truck alongside the R2 SUV, given that the company started with a truck to begin with. We didn’t see an R2T at the unveiling, but maybe they’re still working on that. The silhouette under the cover doesn’t look like a truck – but again, that would be a dead giveaway, so it makes sense they’d just use a default image.

Finally, we reach the last column: “affordable mass market.” This, too, is new, and includes three separate vehicle forms. While we’ve already learned not to trust the placeholder images, note that the images are all different, suggesting that there might be a large, medium and small-size vehicle on this eventual platform.

When R2 and R3 were unveiled, many figured that the R3 would likely be lower price than the R2, which Rivian confirmed – but didn’t go any further than that to state a price range. We assumed it would probably be somewhere around the price level of the Volvo EX30 or Chevy Equinox – somewhere in the mid-30s. We figured this was the next step towards mass-market, as it would be lower in price than the R2.

Another category of “affordable mass market” vehicles suggests either that the R3 will be higher in price than we had thought, leaving room in the low-to-mid 30s for a 4th-gen platform, or it suggests that Rivian is working on a ~$25k vehicle to be in the truly affordable mass market range, among the lowest price level offered for new vehicles by most major manufacturers (and in the future dreams of EV makers, like VW’s ~$22k 2027 offering or the fabled $25k Tesla Model 2).

We also don’t know what size those vehicles will be. They may all be “crossover-like” vehicles like those Rivian currently makes and has announced (the R3 sits somewhere between crossover and hot hatch), and the vehicles under the sheets (which, again, we can’t trust) do look to have “Rivian DNA” and may just be photos of the R1, R2 and R3. But perhaps the use of 3 different vehicle sizes suggests that Rivian might be working on a sedan, a compact, a sporty small car, or something along those lines. The company’s first-ever project was a sportscar, after all.

Or maybe it’s nothing at all. We reached out to Rivian about this and were told “it just demonstrates how our software can scale across platforms.”

But if that’s the case, why not use photos of VW vehicles, or why use vehicles that are clearly Rivian-styled rather than generic lumps? Why have a covered vehicle under the Gen 2 column, which presumably wouldn’t be the architecture used by any partnerships (as MSP would likely be ready by the time this VW partnership bears fruit)? So, we still think there’s something here.

A final note is that, while we did know the R2 was coming and saw several leaks in advance of its unveiling, everyone was blindsided by the R3. Similarly, when Rivian first unveiled its R1T in 2018, it was a complete surprise to everyone despite that the automaker had been founded in 2009 and had been working in “stealth mode” since then. So, Rivian does know how to keep secrets, apparently, and your guess is as good as ours as to what’s under those covers.

What do you think Rivian is hiding? Or is it nothing at all? Let us know in the comments.

Cybertruck recalls, Tesla vs. Camry, Polestar upgrades, and electric flight gets real

We gave the Tesla Cybertruck a lot of heat yesterday, and today we’re back for more as every single example of the controversial electric pickup built so far has been recalled. Meanwhile a Model 3 is cheaper than a Camry now, Polestar 2 gets an upgrade, and electric flight takes off. All this and more on today’s energizing episode of Quick Charge!

I also want to draw attention to yesterday’s Quick Charge episode and say that I didn’t mean for the call for better signage to be a criticism of the signage at Wrigley Field. As many of you pointed out in the comments, the last thing we need as drivers is more signs and more distractions. That said, I stand by the assertion that big signs build confidence in the ICE-driving normies, but the best answer might be something more nuanced than a 60′ EV charging sign.

See? I do pay attention to the comments! (Totally doubling down on that whole “picking on the Cybertruck” thing, though.) Enjoy!

VW will invest up to $5B into Rivian to form joint venture for next-gen EVs

VW will invest up to B into Rivian to form joint venture for next-gen EVs

VW and Rivian have just announced that the two companies will form a joint venture, bringing Rivian’s software expertise to VW’s products and providing an initial $1 billion, and potentially up to an eventual $5 billion, in capital for Rivian to get through its push to deliver its upcoming R2 vehicle.

Rivian is currently working hard to get costs down in its quest for profitability. While the company has large cash reserves, it’s running through them at relatively rapid rate. The financials get a little bit better each quarter, but there is still a lot of work to be done.

Recently, Rivian announced that it would delay building its plant in Georgia in order to save over $2 billion in the short term, helping reduce pressure on its near-term financials.

Now, today, the company has had another pressure valve released, as VW and Rivian have announced they will form a joint venture to bring Rivian’s software to VW’s EVs, with VW offering an initial $1 billion in capital and potentially up to $5 billion by 2026.

“Our customers benefit from the targeted partnership with Rivian to create a leading technology architecture. Through our cooperation, we will bring the best solutions to our vehicles faster and at lower cost. We are also acting in the best interest of our strong brands, which will inspire with their iconic products. The partnership fits seamlessly with our existing software strategy, our products, and partnerships. We are strengthening our technology profile and our competitiveness.”

Oliver Blume, CEO of Volkswagen Group

The partnership is valuable for VW as well, as software has been its biggest issue recently. VW’s previous CEO, Herbert Diess, stepped down in 2022, and it’s thought that software issues were the main reason for his departure. In 2023, VW hired a former Rivian exec to help with software. It must have liked what it got, as the companies are deepening their relationship now.

The partnership begins with VW offering a $1 billion convertible note to Rivian, which will convert into an equity holding around the end of this year.

In addition, the two companies will establish a 50/50 joint venture around “next generation electrical/electronic architecture.” This will give VW immediate access to Rivian’s software architecture, which has been seen as one of the major strengths of the company.

“We’re very excited to be partnering with Volkswagen Group. Since the earliest days of Rivian, we have been focused on developing highly differentiated technology, and it’s exciting that one of the world’s largest and most respected automotive companies has recognized this. Not only is this partnership expected to bring our software and associated zonal architecture to an even broader market through Volkswagen Group’s global reach, but this partnership also is expected to help secure our capital needs for substantial growth. Rivian was created to help the world to transition away from fossil fuels through compelling products and services, and this partnership is beautifully aligned with that mission.”

RJ Scaringe, Founder and CEO of Rivian

After the establishment of this joint venture, VW says it will invest an additional $4 billion into Rivian, in $1 billion tranches in 2025 and 2026, contingent on Rivian meeting “certain milestones.”

After the announcement, RIVN stock is trading up more than 40% in after hours trading. It had already risen 8% during today’s trading session after an analyst upgrade. Rivian will hold an investor call at 3pm Pacific, 6pm eastern here.

Electrek’s Take

This is great news for Rivian, and great news for VW as well.

However, Rivian has had a number of past partnerships that didn’t turn out.

Rivian had previously partnered with Ford to build Ford/Lincoln EVs and also with Mercedes to build electric vans. Both of those fell through, with the Mercedes deal including a joint venture and the Ford deal including a big investment which Ford later trimmed.

Rivian has also partnered with Amazon to deliver 100,000 delivery vans. That partnership is going well with over 10,000 vehicles delivered, but the exclusivity portion of the contract recently ran out, and now Rivian is looking for more purchasers.

In this case, though, I can see a direct reason for Voltswagen to need Rivian’s help. While their software is a lot better now than it used to be, software has been the achilles heel of traditional auto companies in general, and VW specifically. And with VW’s yearly revenue ($335 billion in 2023), they can spare a little change to fix one of their major problems.

One other interesting note: VW recently spun off its classic Scout brand into a Rivian-like adventure EV. That was seen as an attempt to compete in a market that Rivian is currently the best offering in. We wonder if this partnership will include using Rivian’s expertise for the Scout? Stay tuned.
