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.

Buzz tries to undercut Lectric with even lower-priced electric trike

Buzz tries to undercut Lectric with even lower-priced electric trike

Buzz Bicycles has just launched its newest electric tricycle model, pushing prices even lower as older riders continue to gravitate towards electric three-wheelers as accessible e-bikes for both recreation and transportation. Now with the Buzz Cerana T2 hitting the road, the lower end of the market is heating up even faster. And Buzz may now have one of the best-priced mid-drive e-trikes in town.

There’s no shying away from the massive competition in the electric trike space. After Lectric eBikes launched the second generation of the US’ best-selling electric trike model last week, everyone now has a new target to beat. Priced at $1,499, the Lectric XP Trike2 sets a new standard for any retailer that wants to compete on price.

In the weeks since, we’ve seen other e-bike companies roll out their own next-generation models in an attempt to keep up with the driving force in the growing three-wheeler market. But the Buzz Cerana T2 is the first “second-gen” model I’ve seen since the XP Trike2 launch that has actually managed to undercut Lectric’s price. With a $1,399 sticker, the Buzz trike is a solid $100 cheaper.

So what does one Benjamin less get you? Let’s dive in and find out.

Advertisement – scroll for more content

First of all, the Cerana T2 rolls on relatively large wheels, with a 24×3.0″ front tire and 20×3.0″ rear tires. The trike is also powered by a mid-drive motor mounted at the bottom bracket, offering 500W of power.

The product page claims a 20 mph top speed, though that’d be pretty fast for a trike and may be a copy/paste error from another product page, which I’m entertaining as a possibility because right next to it is a graphic touting the rear hub motor – which this trike clearly does not have.

What it does have though is torque, and a lot of it! The mid-drive motor is rated for 130 Nm of torque, which is pretty far up the chart and exceeds the torque output of the vast majority of e-bikes on the market today.

With a throttle on the handlebars, the Cerana T2 qualifies as a Class 2 electric bike, though the five different levels of pedal assist and the cadence sensor mean that riders can also still get a nice workout at varying levels of effort if they choose to ignore the enticing throttle.

Considering the battery is a 48V 10.4Ah unit with only 500 Wh of capacity, pedaling is going to be important if riders want to achieve the claimed 40 miles (64 km) of maximum range on a single charge. If using the throttle frequently, a range of closer to half of that figure is more likely.

And for those who like to keep an eye out for UL certifications, you’ll be happy to hear that Buzz reports full UL2849 certification for the bike.

Other features on the Cerana T2 include the fender set, LCD display, 7-speed shifter, mechanical disc brakes, LED lighting in the front and rear, and an included front rack with matching rear basket.

There’s also an oversized saddle that features a manual drop post. It’s a hand lever found under the saddle that can instantly drop the post down several inches – a great way to quickly lower the seat when coming to a stop to dismount. It’s always a great way to get people to raise an eyebrow the first time you fiddle around for it in a fairly… intimate location.

Electrek’s Take

On the one hand, it feels a bit unfair to compare the Buzz Cerana T2 to the Lectric XP Trike2 instead of discussing this new model in its own right. But on the other hand, it’s one of several second-gen trikes to recently hit the market in the wake of the Trike2’s groundshattering unveiling, so I’d be doing the journalistic version of closing my eyes, putting my hands over my ears and shouting “La la la la!” if I pretended the two unveilings weren’t at least somewhat related.

Of course everyone is looking to save a buck (or a hundred of them) where they can, and the Cerana T2 even offers some cool things the XP Trike2 doesn’t, such as that dropper seat post and the mid-drive motor – though I’m not sure if the cadence sensor is worth it, not to mention that the XP Trike2’s jackshaft motor is essentially a hub motor functioning as a mid-drive. And while the Cerana T2’s lack of suspension is disappointing, the 3″ tires will help earn back some of the cushion lost to a rigid fork and frame.

On the other hand, the Cerana T2 has a few downsides, such as the lower-end mechanical disc brakes and the lack of a folding frame.

But hey, if it can really do 20 mph on the straightaways, then that might be its biggest selling point right there – other than the $1,399 price. Just watch out for those turns…

Rivian (RIVN) to open a UK office that will focus on AI and autonomous driving technology

American EV automaker Rivian is expanding across the pond into the UK, hoping to tap into the region’s talent pool in artificial intelligence engineering.

Rivian is a growing American EV brand with expanding office footprints as much as its lineup of unique electric trucks and SUVs. The company is currently headquartered in Palo Alto, California, with its main production facility located in Normal, Illinois alongside plans for a second production footprint about 40 minutes outside of Atlanta, Georgia.

Other US locations currently include offices in Irvine and Carson, CA, Wittmann, AZ, and Plymouth, MI. Outside of the US, Rivian operates out of offices in Vancouver, BC, Canada, Amsterdam, Netherlands, and Belgrade, Serbia.

This morning, Rivian announced its latest international office in London, UK, which will become an AI-centric development hub.

Rivian to open AI Hub in the UK

According to a release from Rivian early this morning, it sees the UK as rapidly becoming a world leader in artificial intelligence engineering, and is looking to tap into that talent pool with the new international office.

While Rivian’s current Autonomy Platform enables drivers to utilize hands-free, eyes-on highway driving, the American automaker intends to continue to evolve such tech to offer greater levels of autonomous capabilities.

Rivian shared that its second-generation EVs were designed with an “AI-centric approach.” As its Gen2 vehicle fleet continues to develop and grow, the automaker has been collecting more and more data to help accelerate the improvements to ADAS technology. Per the company:

Rivian believes the combined strength of its perception platform and in-vehicle data infrastructure will enable it to build a Large Driving Model, unlocking unparalleled understanding of complex driving scenarios and accelerating the path to safer, more capable autonomous features.

Rivian said the future work done at its new UK AI hub will enable its EVs to improve in the future via over-the-air (OTA) updates. Details remain light, but Rivian shared plans to host an “AI and Autonomy Day” later this year and promised to share more about its product and technology roadmap.

A golf cart pickup truck? GEM-maker launches diverse new LSV line

A golf cart pickup truck? GEM-maker launches diverse new LSV line

Waev, the company best known for its iconic GEM electric low-speed vehicles (LSVs), just unveiled a brand new lineup of commercial electric carts and LSVs. And this time, they’re not messing around when it comes to utility. Dubbed the Fusion line, these new lithium-ion-powered vehicles include mashups plucked from the worlds of golf carts, street-legal shuttles, and jobsite pickup trucks.

The Fusion lineup includes six different models: three designed for people-moving and three built for utility work. But all six still seem to be aimed squarely at commercial, municipal, and industrial fleets.

Whether that’s running security at a stadium, shuttling guests at a resort, or hauling equipment around a worksite, there looks to be something in the Fusion family that probably fits the bill.

On the people-moving side, Waev is offering 4, 6, and 8-passenger models, all of which feature a flip-up rear seat that converts into a cargo deck, a near ubiquitous feature among modern golf carts and LSVs with rear-facing benches that helps them pull double duty as a light utility vehicle. The feature gives them added flexibility for things like maintenance staff, hospitality transport, or even large campus tours, letting them carry a large number of passengers, yet still be capable of stacking boxes or equipment in the rear.

The utility versions look a bit different with more muted matte black bodywork, plus come with electrically-actuated hydraulic dump beds, 2-inch ball hitches, and even orange seat belts for jobsite visibility. It’s harder to forget to put on the seatbelt when it’s blindingly orange.

And yes, the Fusion Utility Long Bed basically looks like a pickup truck built on a golf cart chassis, which I find equal parts strange and endearing. But then again, I’m the guy who infamously kicked off the great American mini-truck trend a few years ago when my hilarious little tiny-truck went viral, so maybe I’m a bit biased when it comes to fun little utility vehicles.

All Fusion models are available in both “cart” and “LSV” configurations. The carts are speed-limited to 19 mph (30.5 km/h) and come with serial numbers, making them street-legal only in limited areas that have passed local ordinances permitting golf carts to use public roads.

The LSV versions get full VINs, meet federal low-speed vehicle safety standards (meaning over a dozen regulations on manufacturing standards and safety equipment), and can be driven up to 25 mph (40 km/h) on public roads where LSVs are permitted by state law.

Waev is sticking with lithium-ion power here, specifically a 105Ah Marxon pack that’s both heated and insulated for cold-weather use. That’s a big step up from the old-school lead-acid setups still found in some fleet carts (and, if we’re being honest, still offered on some of Waev’s other vehicles).

The company claims to offer automotive-grade manufacturing processes and reliability on its vehicles, along with Bluetooth diagnostics and a smartphone app for managing the fleet.

Other upgrades include LED lighting, back-up cameras, AVAS pedestrian alert systems, and standard three-point seat belts for all passengers. Optional extras like ladder racks, beacon lights, and upgraded tires make it even easier to tailor each unit to the specific job at hand.

The Fusion line slots into Waev’s already broad family of low-speed EVs and fleet vehicles, including the steel-bodied Taylor-Dunn utility vehicles, Tiger heavy-duty tow tractors for airports and warehouses, and the classic GEM lineup that’s been a staple of street-legal fleet transport since the late ‘90s.

It also looks like Waev isn’t just trying to sell the hardware here – it’s pushing hard on full-service fleet support, too. The company is leaning on an extensive dealer network across the U.S., Mexico, Canada, and Australia, and all Fusion models are available through Sourcewell and Canoe procurement programs for simplified public-sector purchasing.

One big thing we’re not seeing, though, are the prices. It’s more of a “contact us for a quote” situation, which means exactly what you think it means. We’ll try to learn more, but don’t expect to make it out of the lot without a measurably lighter wallet.

Electrek’s Take:

This is the kind of product line that probably won’t turn heads in your local grocery store parking lot, but it’s exactly the kind of quiet EV revolution that’s transforming fleets behind the scenes. Lithium-ion golf carts and LSVs that can tow, haul, and shuttle without the noise or emissions of gas engines? That’s a win for everyone –from municipal fleets to private campuses.

And frankly, I’m here for the golf cart pickup truck vibe. Street legal, work-ready, and just weird enough to be cool. The fact that the tailgate seems to swing all the way down and doesn’t lie flat like a normal pickup truck’s gate was a swing-and-a-miss by the designers – I don’t know how that got through – but everything else looks great! And hey, I guess I could always add a pair of tailgate cables if I wanted.
