Floating Solar Plus Wave Energy Smackdown For Fossil Fuels
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.

File this under “wishful thinking” if you want, but a fresh trademark filing for the Buick Electra name could mean that the storied nameplate is set for a return to US shores.
GM Authority reports that Buick parent company General Motors has renewed its trademark for the Buick Electra name in the US in a filing from 09DEC2025 with the United States Patent and Trademark Office (USPTO), and received an assigned serial number 99538079. The application carries a Goods and Services of, “Motor land vehicles, namely, automobiles.”
Electra a nameplate that holds a long history with the near-luxe Buick brand and has generally been believed to be one that’s especially relevant to Buick’s electrification strategy in the US. That’s a notion that seems especially true when you consider the following two facts:
- the Buick Electra nameplate is already featured on a number of hugely successful GM products being sold in the ultra-competitive Chinese market
- 2027 is the fortieth anniversary of the Buick Grand National, and GM’s marketers are way too smart to let that moment slide
It’s worth noting, of course, that this most recent renewal for the Buick Electra trademark is a long, long way from a confirmation of a new all-electric Buick for the US market and even further from a confirmation that we’re getting the hot, sexy Electra GM sells in China. If anything, it’s likely just a matter of course legal thing that GM needs to protect its IP in China while, at the same time, preventing some kind of disastrous Sierra Mist scenario from playing out at home (which– yeah, I get that it’s not true, but you got the idea).
That said, I want to believe.
Electrek’s Take
I’m a huge fan of GM, GM’s EVs, and the way Mary Barra has managed the General over the past several years. I also think a big, sexy sedan is sorely missing from GM’s lineup, and the fast, flashy electric sedan formula might play better at the Buick store than at the Cadillac brand.
Combine that with an overwhelming desire to see a new-age Buick Grand National parked in my garage next Christmas and you can see that I’m not to be trusted. So, what say you? Head on down to the comments and let us know what you think of an American Electra revival just in time for the 2027 model year.

Heavy equipment giants Caterpillar have signed an agreement with Vale that will see the company dramatically expand its fleet of autonomous haul trucks deployed at iron ore operations in the Carajás region of Brazil over the next three years.
Vale’s Northern System mining operation currently has 14 CAT, 320-ton autonomous haul trucks in service. With this new deal, sold by Caterpillar’s Brazilian dealer, Sotreq, the autonomous haul truck fleet will expand to some ninety (!) of the massive, self-driving trucks by 2028. The big yellow trucks will be operated by CAT®, MineStar™ Command for hauling, and ship with a payload capacity of between 240 to an almost unimaginable 400 (!!) tons.
“We’re proud to introduce Cat Command for hauling at Vale’s Carajás site,” says Marc Cameron, Senior Vice President at Caterpillar. “By equipping Vale’s haul trucks with our autonomous technology, we will be delivering scalable solutions that meet their needs across a mixed fleet.”
CAT says this new deal represents, “a transformational leap,” citing the fact that autonomous trucks remove workers from hazardous areas and enable safer and more inclusive environments for mine employees – and more efficient operations for Vale.
That fact is backed by results from other Vale operations that have deployed large numbers of autonomous vehicles, which saw gains of up to 15% in operational performance and a 7.5% reduction in fuel use (more with electric drive), contributing to the reduction of the company’s carbon emissions. And, because this is end-stage capitalism 2025, they’re crediting AI for discovering those efficiencies.
“By integrating autonomous systems, artificial intelligence, and advanced data analysis, we are modernizing our mining operations in the Northern Corridor, becoming a global benchmark in smart mining, promoting the transformation of the industry, and connecting us to international best practices,” says Rafael Bittar, Vale Vice President, Technical.
The trucks will be delivered over the next three years, and are expected to be in full operation and up to speed by 2030.
Electrek’s Take
As I’ve said before, EVs and mining to together like peanut butter and jelly. In confined spaces, the carbon emissions and ear-splitting noise made by conventional, ICE-powered mining equipment can create dangerous circumstances that can lead to serious injuries (or worse), and that’s just going to make it even harder for a mining operation to keep people working and minerals coming out of the ground.
By working with companies like Caterpillar to prove that forward-looking electric equipment can do the job as well as well as (if not better than) their internal combustion counterparts, Vale will go a long way towards converting what’s left of the ICE faithful.

Electric medium-duty startups Motive and Workhorse have logged millions of miles across their customer fleets — and by joining forces, they’re out to prove, once and for all, that electric vehicles can get the job done.
Following shareholder votes last month, Ohio-based Workhorse and San Francisco-based Motive are merging to form one of the largest commercial electric vehicle and last-mile delivery telematics solutions companies in the industry.
The all-stock transaction, announced last week, values the combined company at approximately $105 million and is expected to close in the fourth quarter of 2025, subject to Workhorse shareholder approval.
Under the terms of the agreement, Motiv’s controlling investor will become the majority owner with approximately 62.5% of the combined company, while Workhorse shareholders will maintain a significant equity stake of approximately 26.5%.
The move is intended to combine Workhorse’ manufacturing capabilities and nationwide dealer network with Motiv’s proven product portfolio and existing fleet relationships to serve the growing $23 billion medium-duty truck segment with a full range of Class 4-6 electric vehicles that plays to the strengths of both companies while, at the same time, proving them with economies of scale they’ll need to survive the next wave of fake “the EV market is dead” headlines.
“Bringing together two leading OEMs in the medium-duty space strengthens our ability to reduce the cost of electric trucks and make the total cost of ownership even more compelling,” said Scott Griffith, CEO of Motiv, who will lead the combined company. “We believe this is a coming-of-age moment — not just for Motiv and Workhorse, but for the industry as a whole.”
The companies anticipate a minimum of $20 million in cost synergies by the end of 2026 through reductions in redundant R&D, G&A, and facility costs (and, of course, the associated layoffs).
Workhorse’s Union City facility has the capacity to eventually produce up to 5,000 trucks per year — a significant manufacturing scale for the merged operation and light years ahead of what Motiv’s existing facilities can crank out.
“This transaction represents a significant milestone for Workhorse, our customers, our stakeholders and our shareholders,” Rick Dauch, CEO of Workhorse and advisor to the new, combined company told FreightWaves. “We believe Motiv is the right partner to support the advancement of our combined product roadmap and capture new growth opportunities.”
The new, combined electric box van company will being life with 10 of the largest medium-duty fleets in North America as existing customers, and hopes to expand their line of offerings into the electric bus and RV markets in the years to come.
Electrek’s Take
Workhorse and Motive can spin this merger however they like — but this move is as much about survival in the new, incentive-lite era of Trump 2 than it is about anything else. That doesn’t mean it’s not a smart move, as each of the parts of this new whole has eliminated a very strong competitor while, at the same time, gaining all at least some of their best features.
As cynical as I am about corporate consolidation and layoffs (especially during the holidays), I can’t help but think this could be a winning move.
