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.

Flying cars are no longer just for the movies. Alef Aeronautics has begun building the first electric flying cars for customers, which are being hand-made in California.
Electric flying cars are real and hand-made in the US
It sounds like something from The Jetsons or Harry Potter, but flying cars are becoming a reality. Alef has been developing all-electric flying cars for about a decade now.
After unveiling a prototype in 2016, the company secured backing from early Tesla and Bitcoin investor Tim Draper. Draper became a pioneering investor and mentor to the team.
The big funding round propelled Alef to create not just a toy, but a flying car that can be used as an everyday commute vehicle.
In 2018, the company’s first full-size “skeleton” was flown, and the following year, the first prototype was shown to a group of investors.
Alef introduced its first model, dubbed the Model A, in 2022, a 100% electric flying car that can drive 220 miles with a 110-mile flight range.
Less than a year later, it became the first to receive a Special Airworthiness Certification from the US Federal Aviation Administration while securing its first pre-orders from a car dealership.
We got our first look at the flying car in action earlier this year after Alef released a video of an ultralight Model A jumping over other vehicles, including a Tesla Cybertruck (see the video below). According to Alef, it was the “first-ever video in history of a car driving and vertically taking off.”
In its mission to make flying cars a reality, the California-based startup announced another major milestone on Monday.
Alef said it has begun manufacturing the first flying cars for customers at its facility in Silicon Valley, California. The first models are being hand-made and will be delivered to just a few early customers “for the purpose of testing flying cars in the real world environment,” according to Alef.
The company plans to train and support early adopters, using lessons learned as it ramps up production and deliveries.
“We are happy to report that production of the first flying car has started on schedule,” Alef’s CEO, Jim Dukhovny, said at the event.
Alef claims its flying cars are “100% electric, drivable on public roads, and has vertical takeoff and landing capabilities.”
The startup has already received 3,500 pre-orders, which it says is worth $1 billion. Alef’s flying car is expected to start at around $299,999. You can pre-order one on Alef’s website with a $150 deposit, or you can secure a spot in the priority queue for $1,500. The first customer deliveries are expected to begin in 2026.

Ford is promising that more affordable EVs are coming soon. A new partnership will include two Ford-branded electric vehicles, but that’s just the start.
Ford and Renault partner up on affordable EVs
“We know we’re in a fight for our lives,” Ford’s CEO Jim Farley warned on Monday (via CNN) before announcing a landmark partnership with Renault to develop more affordable EVs and fend off surging Chinese brands like BYD and SAIC’s MG.
Ford said the new partnership is “a first step,” as part of a broader restructuring in the region. The plans include two new Ford-branded EVs, based on Renault’s Ampere platform.
Although they will share underpinnings with the popular Renault 5, the American automaker will lead the design to “ensure these vehicles are distinctly Ford.”
The first is expected to be an electric successor to the widely popular Fiesta, while the second is rumoured to be a small EV crossover, similar to the Renault 4.
Ford didn’t offer specifics, but said the first vehicles will begin arriving in showrooms in 2028. Farley told reporters that the new EVs will be smaller than anything planned for the US, as it seeks to fill a critical gap in its European lineup.
“As an American company, we see Europe as the frontline in the global transformation of our industry,” Farley said, adding that “how we compete here will write the playbook for the next generation.”
The partnership will also include jointly developing Ford and Renault-branded commercial vehicles using common platforms.
Ford’s current EV lineup in Europe consists of the Electric Explorer and Capri, which share a platform with the Volkswagen ID.4 and ID.5, and the Puma Gen E.
The news comes just a day after Farley warned that the EU’s emissions rules are “risking the future” of the auto industry.
Electrek’s Take
Ford initially backed the EU’s push to have all-electric vehicle sales in the region by 2035, but now it’s blaming slower-than-expected EV demand and calling for looser rules.
Farley has warned several times now that Chinese automakers, like BYD, are an “existential threat” to the auto industry. As part of its restructuring, Ford has already announced plans to cut thousands of jobs in Europe while reducing output at its Cologne EV facility.
Ford’s share of European passenger car sales has plummeted from 6.1% in 2019 to just 3.3% through October of this year.
Although the company is blaming slower EV demand, electric vehicles are still gaining ground in Europe. Through October 2025, nearly 1.5 million EVs were registered in Europe, accounting for 16.4% of the market. That’s up from around 13.2% through the first 10 months of 2024.
Meanwhile, the combined share of petrol and diesel cars fell to 36.6% from 46.3% over the same period.
Are EV sales slowing? Or, is it a Ford problem? The new alliance with Renault to build more affordable EVs will be critical to Ford’s comeback in the region.
