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.

This battery pack makes Tesla Roadster 400 lbs lighter, but it ain’t cheap

This battery pack makes Tesla Roadster 400 lbs lighter, but it ain't cheap

A battery pack manufacturer has released a new solution for Tesla Roadster with aging battery packs. It would slash the car’s weight by about 400 lbs, but it’s not cheap.

In many ways, the Tesla Roadster sparked the electric vehicle revolution.

It was the first commercially available consumer EV with lithium battery cells – enabling over 200 miles of range on a single charge.

The vehicle had comparable or better performance than many other gas-powered vehicles in its segment.

The Roadster had its problem. It was a suboptimal solution as it was still heavily based on the Lotus Elise and not designed from the ground up to be electric, but it did its job as a proof-of-concept.

Tesla only manufactured about 2,000 of them between 2008 and 2011 before moving on to the Model S and other vehicle programs that were built to be electric from the ground up.

Despite being 13 to 16 years old, many Roadsters are still doing well. Electrek’s own Jamie Dow drives his daily. That’s despite Tesla not doing anything with the Roadster program since 2017 when it launched the Roadster 3.0 replacement pack.

Battery technology has improved a lot since then, and a company has decided to take advantage of that and offer a new battery pack for Tesla Roadster owners.

re/cell, a Texas-based supplier of remanufactured battery packs for EVs, has unveiled a new Roadster battery pack that aims to slash hundreds of pounds off of the sports car.

Unlike Tesla’s latest vehicles, which are equipped with skateboard-like platform battery packs, the Roadster has a pack that sits behind the seats in the back and the modules are in the shape seen above.

It does cause problems with balancing the weight of the vehicle.

The pack is able to achieve the Roadster’s peak power output, but it should be a lot more fun to drive by shaving up to 400 lbs off of the car’s original 2,877 lb (1,305 kg) weight.

It does come with a lower energy capacity than the original 53 kWh, but you should be able to achieve very similar range (over 220 miles) thanks to the efficiency gain from the weight loss.

Here are the full specs of re/cell’s new Roadster battery replacement pack:

  • Peak Power Output: 260 kW / 285 kW
  • Weight Savings: up to 400 lbs / 180 kg
  • Volume Savings: 3.7 cu ft / 100 liters
  • Energy Capacity: 38 kWh / 47 kWh
  • Rated Range: 220-240 miles / 350-390 km
  • Cell Type: 18650 / 3500 mAh
  • Cell Configuration: 31p99s / 39p99s

re/cell describes some of the improvements that they were able to make to the pack:

The revolutionary cooling-block design is a single-piece molded core with Palladium-class cooling ribbons for improved cooling and temperature management. The contact area for heat transfer is 50x larger than the cooling tubes used in the original Roadster sheets and the overall surface area for cooling and heating is now more than double. No more vacant cooling voids allowing for hot spots or uneven cooling or heating – the entire cell is now fully encapsulated and temperature controlled!

However, this offer is not going to be for everyone since Roadster owners need to be willing to invest $28,000 in their aging vehicle, which is the price of the pack if you give your existing pack to re/cell.

Interestingly, the company is also thinking about offering other upgrades that can be enabled by space freed up by the new pack.

For example, re/cell believes it would be easier to make the pack capable of DC fast-charging. liquid cooling for the PEM and Motor 

Electrek’s Take

I really enjoyed driving the Roadster 3.0, and I’d be curious to see how much better it would handle with 14% less weight.

There are just no other electric vehicles out there that weigh just 2,400 lbs. Even a Fiat 500e weighs nearly 3,000 lbs.

I can’t wait for small electric sports cars around 2,500 lbs. They should be so much fun and it sounds like this, despite not being designed from the ground up for it, could be an interesting preview.

And there’s not better way to power your electric sports car than with solar. If you want to make sure you’re finding a trusted, reliable solar installer near you that offers competitive pricing, check out EnergySage.

Coinbase, a16z and others pour more than $78 million into pro-crypto PAC for 2026 election

Coinbase, a16z and others pour more than  million into pro-crypto PAC for 2026 election

Crypto donor Chris Larsen on why he's giving millions to the Harris campaign

With one day to go until the U.S. general election, crypto companies have already poured tens of millions of dollars into the upcoming 2026 cycle. The pro-crypto and bipartisan super PAC Fairshake said Monday that the committee and its affiliates have raised $78 million for the 2026 midterm elections.

That $78 million breaks down to more than $30 million raised, plus another $48 million in new commitments from centralized crypto exchange Coinbase and Silicon Valley venture fund Andreessen Horowitz, among other companies.

Early Monday, a16z general partner Chris Dixon, who heads up the fund’s crypto book, published a note explaining why the company contributed another $23 million to Fairshake.

“Regardless of what happens in the 2024 elections, we’re committed to supporting policymakers, irrespective of party affiliation, who will work to establish a practical regulatory framework that protects consumers while allowing the industry to grow,” the letter read.

Dixon added that “supporting a PAC like Fairshake is just one crucial part of the strategy needed to achieve our larger policy goals” and that a16z would continue to meet with policymakers on both sides of the aisle to advocate for the industry.

All in, a16z has given $70 million to Fairshake as the VC looks to support the PAC’s larger mission of building a Congress comprised of pro-crypto legislators.

On Wednesday, Coinbase announced it would give another $25 million to Fairshake.

Coinbase, the largest U.S. crypto exchange, was sued by the Securities and Exchange Commission over claims that it engaged in unregistered sales of securities. It’s among Fairshake’s top contributors this cycle. The exchange has given more than $75 million to Fairshake and its affiliated PACs.

“We know we need to have pro-crypto legislation passed in this country,” Coinbase CEO Brian Armstrong said during the company’s third-quarter earnings call. Coinbase shares plummeted 15% after the company reported a miss on the top and bottom lines.

Ripple Labs is another major political donor this cycle that has given around $50 million to Fairshake. A spokesperson said the company committed $25 million both this year and last year and intends to remain a strong force in DC for years to come.

Coinbase's legal chief on crypto's 2024 election spending

Fairshake told CNBC it’s raised around $170 million this cycle and disbursed approximately $135 million.

The majority of the group’s funds can be traced to Coinbase, Andreessen Horowitz and Ripple Labs. The remaining balance comes from a mix of companies and individual donors. Armstrong, for example, gave $1 million, while the Winklevoss twins put in $5 million.

Fairshake was launched last year by a consortium of crypto firms and is one of the top-spending PACs in 2024, even against oil companies and banks, which have historically been big political contributors. Nearly half of all the corporate money flowing into the election has come from the crypto industry, according to a report from the nonprofit watchdog group Public Citizen. 

Fairshake’s spending, which has targeted House and Senate races in the 2024 cycle, is effective. Public Citizen’s report found that of the 42 primary races that attracted money from crypto-backed super PACs, 36 were won by the candidate supported by the crypto industry.

Fairshake’s corporate and individual donors want crypto laws passed in the U.S.

Dixon and others say they’re looking for comprehensive market structure legislation for digital assets and a law to govern stablecoins, tokens pegged to the value of a real-world asset that are now virtually synonymous with U.S. dollar-pegged coins.

“Many industries come to DC asking to roll back rules, and we have come to DC asking to establish them,” Dixon wrote in his post Monday.
