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.

Japanese equipment giant Komatsu dropped its new, 320-ton Power Agnostic 930E mining truck at MinsExpo trade show in Las Vegas, calling it a future-ready solution that can run on diesel, hydrogen, or pure electric power.
Komatsu continues to develop alternative engine technology with the release of its first commercial rigid-frame dump truck with a “power agnostic” platform for running on diesel, hydrogen, or even battery electric power.
That’s because the platform is designed around the concept of a modular powertrain. The design not only gives the Komatsu assembly line an easy way to build diesel, BEV, and hydrogen fuel cell rigid haulers on the same line, but also enables customers to upgrade from diesel to battery electric or hydrogen down the road, if and when whatever logistical obstacles that are preventing them from running an electric or hydrogen solution today are overcome.
“This platform enables mining companies to start with conventional diesel engines and gradually transition to cleaner energy sources as needed, including utilization of trolley assist for diesel or as one of the future dynamic charging solutions for battery trucks to reduce fuel consumption and emissions,” reads Komatsu’s press material. “Whether adopting battery technology, hydrogen fuel cell technology or a combination of energy systems, the Power Agnostic 930E provides the infrastructure and adaptability necessary to meet evolving sustainability goals.”
Potential customers got a sneak peek at the concept truck, which they were apparently allowed to test at Komatsu’s Arizona proving grounds ahead of MineExpo (I wasn’t invited). The first pre-production Power Agnostic 930E prototype will make its way to Sweden in the coming months, where it will be put to work alongside other electric Komatsu machines in Boliden’s Aitik copper mine, one of the largest such operations on the European continent.
Electrek’s Take
Converting gas and diesel-fueled cars to electric at scale is a concept that’s fraught with problems. Far too many to list here, in fact. But heavy equipment?
Everything from excavators to loaders to heavy trucks are already built to be powertrain agnostic, and manufacturers will often offer the same basic vehicle with Cummins, Detroit Diesel, or Volvo Pentapower, so there’s a degree of openness baked into those systems already. Komatsu is just taking that to the next level by adding a modularity of energy storage (fuel tanks, hydrogen cells, or battery packs) to the mix. And, if the project is successful, it could be the first of many.

It’s no Ferrari, but owning a sporty little Fiat 500e is about as close to putting a cavallino rampante in the garage as most of us will ever get. And if we act soon, we could do just that for 30% less money than before.
Fiat parent company Stellantis is giving dealers the ability to offer buyers up to $3,000 in coupons and incentives to help move its slow-selling 2024 FIAT 500e coupes. When paired with a $7,500 factory lease credit through Stellantis Financial, those coupons lead CarsDirect analysts to call the 500e one of the most affordable new EVs on the market.
The math maths
Between coupons and Stellantis Financial cash, that’s $10,500 in potential discounts before negotiations even begin. With a base MSRP of $34,095 with destination for a 2024 500e, that’s a JC Penney-style 31% off, with an additional 2% (presumably) within easy reach.
According to CarsDirect, the biggest downside of the coupon program is that it’s still unadvertised, which means there’s no way of telling how much of the allowable discount dealers are actually including in prices. But (as GI Joe taught us) knowing is half the battle, so click here to find deals on a new Fiat 500e near you, and make “are you applying those $3,000 in Stellantis coupons” one of your first questions.
Electrek’s Take
Small cars have never sold well in America. Not even great ones like the OG Honda CRX or Suzuki Swift GTi. Americans tend to buy for low use case scenarios, which is a fancy way of saying that, if an American thinks they’ll need a pickup 2-3 days/year, they’ll convince themselves to drive a pickup for the other 362 days. The British want more taxes than Americans wanted to pay in 1775, and today we have more gun shops than McDonald’s … just in case.
The little Fiat, in other words, was never going to be a volume player in the US. And that’s too bad, because the little 117 hp microcar is, by all accounts, fun to drive, zippy, and unquestionably cool. The media at large, though, has complained about the 37 kWh battery and 149 miles of EPA range – calling both “inadequate,” despite the fact that the first-generation Nissan LEAF had objectively inferior specs and sold 200,000 examples before getting its first significant upgrade in 2016. And, frankly, that Nissan had about as much style as a hospital gown.
So, while it may not offer what most car buyers think they need – as a second car, or a fun, urban runabout for lighthearted singles, the little Fiat is tough to beat (especially in red).
