Imagine an electric grid powered by clean, renewable energy. Now imagine that this grid provides all the comfort and convenience consumers have come to expect as well as grid reliability and resiliency services that are similar to—or better than—conventional plants. That is the promise of the FlexPower project.
With support from the U.S. Department of Energy Grid Modernization Laboratory Consortium, FlexPower brings National Renewable Energy Laboratory (NREL) researchers together with other National Laboratories to develop a colocated variable hybrid generation power plant enhanced with energy storage at NREL’s Flatirons Campus. Participants include the Idaho National Laboratory (INL) and Sandia National Laboratories (Sandia).
As renewables displace conventional generation, hybrid renewable power plants combined with energy storage can transform variable resources such as wind and solar photovoltaics (PV) into fully dispatchable and flexible energy sources. These hybridized power plants will be capable of operating in day-ahead and real-time energy markets and providing essential reliability and resiliency services to the grid.
Rethinking Renewables
“This research will help accelerate the adoption of utility-scale variable wind and PV resources by demonstrating how hybridization can smooth the transition to clean energy,” said NREL Chief Engineer Vahan Gevorgian. “For the power grid to economically and reliably integrate large amounts of variable renewable generation, it will require robust energy storage capabilities and a rethinking of the value renewable energy assets bring to the grid.”
To support this transformation, researchers will test a variety of energy storage systems, including pumped storage hydropower, battery, hydrogen, flow battery, kinetic, and ultracapacitor energy storage. In addition, the project will focus on advanced control strategies and resource forecast techniques. Sophisticated controls can improve the dispatchability and availability of variable generation by taking advantage of the complementary nature of wind and PV resources and increasing capacity factors for renewable projects with minimum or, in some cases, no additional transmission buildup. Improved forecasting allows hybrid plants to participate in energy and ancillary services markets in the same way conventional generation plants do.
By combining generation, storage, advanced controls, and improved forecasting in hybrid plants, operators can achieve economies of scale by sharing infrastructure as well as siting and permitting costs. These plants can also provide the full spectrum of existing essential reliability services as well as new, evolving grid reliability services. For example, hybrid plants can provide self-black starts as well as power system black starts, can operate in islanded mode, and can participate in power system restoration schemes. And hybrid plants are scalable, ranging from small microgrids to large, interconnected power systems.
The FlexPower project is of great interest to a wide range of stakeholders, including regulators, reliability organizations, system operators, utilities, plant owners and operators, equipment vendors, and island power system owners and operators.
“Hybrid renewable energy plants could introduce the national and global energy sectors to a new and potentially disruptive class of power systems,” Gevorgian said. “The FlexPower project will demonstrate the value of renewable energy assets and suggest strategies for using them more efficiently to reduce curtailment, increase energy production, and smooth variability. The result could be high-value grid services and a more secure and resilient power supply.”
Sharing the Findings
The FlexPower research results will be freely accessible to all stakeholders in the form of public domain information and other assets. Specifically, stakeholders will have access to the FlexPower controller architecture; control codes developed by NREL, INL, and Sandia for industrial control platforms; hybridization-potential assessment maps and databases; results of regional impacts studies; and reports, publications, regional webinars, conference presentations, and other outreach materials.
NREL’s Flatirons Campus grid-scale hybrid system will provide a test bed for companies and researchers to validate and demonstrate their hybrid plant concepts and strategies. The fully operational multi-MW hybrid power plant will be capable of demonstrating all types of dispatchability, reliability, and resiliency services. It will also provide a grid-scale test bed that offers hybrid system demonstrations for a range of stakeholders, opportunities for control and equipment vendors to test new hybrid controls and hardware, a venue for workforce education and new international collaborations, and a validation platform for standardizing hybrid technologies.
Guys, I think JackRabbit has a two-person e-bike coming, errr… electric scooter? I’m not really sure what you call this thing, but it looks wild.
I recently took a short break from riding and writing e-bikes all day to doomscroll social media, which basically just feeds me more bike content all day. And what popped up in my feed other than this peculiar thing?
Sure, it’s obscured by a surfboard mount, but there’s no getting around the fact that it looks like this shiny new silver JackRabbit isn’t quite as mini as we’re used to from the famously “micro and proud” micro e-bike maker. And there’s one other detail that’s also apparent if you look closely.
It’s a two-seater.

I think this video was meant to be something of a teaser from JackRabbit, but it might as well be a near-unveiling.
In other parts of the same teaser video, almost the entire bike is visible. From those other shots, we can see that it’s still not quite an e-bike in the traditional “comes with pedals” sense.
Instead, JackRabbit’s somehow simultaneously chunky yet tiny folding footpegs are still visible. The wide handlebars also appear to have JackRabbit’s unique 90º turning handlebar lock, which allows the bars to spin sideways when parked. You can even see it in use in the images below.
On JackRabbit’s smaller models, that trick makes the entire bike just 7″ (17 cm) wide, making it easy to store behind a couch or under a dorm bed. Here, it’s unclear if it will be quite as narrow, but it should still make this a conveniently stowable ride.
It’s hard to tell, but it looks like the wheels might be larger than JackRabbit’s standard 20″ size, helping give it the “full-sized bike” qualifier that JackRabbit claims in the teaser video. The perspective is confusing, as the front wheel looks closer to 24″ or 26″, yet the rear wheel still disappears behind that surfboard. Could this be the first mullet JackRabbit? (Not to be confused with a JackRabbit mullet, which is a hairstyle that would pair well with what is likely the most free-spirited of all the e-bike brands out there.)
There may also be different saddle options, since we can clearly see what looks to be a conventional bicycle saddle in some images and a longer, stretched-out, banana seat-style saddle in the other shots.
We can also see two of JackRabbit’s “Rangebuster” batteries in the frame, a larger capacity pack developed by the company with a claimed 24 miles (39 km) range per battery, meaning this model might have a range of nearly 50 miles (80 km).
But there’s a lot we still don’t know. Will it get the powerfully torquey motor from the JackRabbit XG Pro? Will there be a pedal option? Will my wife agree to ride this thing with me? These are yet questions without answers, people.
One thing is for sure, though. JackRabbit says all will be revealed soon. “Everything you know about JackRabbit is changing on 8/12,” writes the company. (That’s next week, for any Europeans in the room.)
I don’t know about you, but I’m suddenly very much looking forward to Tuesday.
Electrek’s Take
I don’t know what to make of this, but I’m excited. I’ve been a JackRabbit fan since before the OG was even the OG. It’s just such a fun and free-spirited brand.
If the e-bike market was high school, JackRabbit would be that quirky, non-conformist kid that everyone kind of wondered about but who was obviously having more fun than anyone else. It’s the e-bike that just puts its hands over its ears and goes “La la la la…” when you try to tell ’em that it’s not actually an e-bike.
It’s weird. It’s wild. But it works. And being a JackRabbit fan is a hill I’m prepared to die on – though admittedly, you’d be well advised to tackle that hill on one of the Pro models instead of the OG2 for the extra power and torque.
My wife might give me a funny look every time I whip out my JackRabbit, but I still love riding it. And so it’s with that level of excitement and curiosity that I wonder what the brand that refuses to be defined is up to with this new “full-sized bike” reveal they’ve got coming. The ability to carry two riders sounds great, especially since the thing still looks so small and portable.
Of course, the over-priced elephant in the room is that JackRabbit’s Achilles heel is its pricing. These things aren’t cheap. The entry-level OG2 model only starts at $1,249, and the flagship XG Pro is almost double that. Granted, it’s an awesome bike, and one that I was able to use to tow a kayak down the road for miles, then put on top of that kayak and paddle through the Gulf of Mexico for miles (something of which I don’t know of any other e-bike that can do). But that makes me wonder what yet a bigger and presumably more impressive JackRabbit will cost.
But hey, I’m so here for this!

Small package, big impact: that’s the story behind Maxon’s new Air S mid‑drive motor. On the surface, it looks almost identical to the original Air: sleek, nearly invisible, and designed to disappear into your bike’s frame. But beneath this minimalist exterior is a dramatic leap in capability.
Now the torque has nearly tripled, soaring to 90 Nm, all while keeping total system weight to just 3.8 kg, (8.4 lb) including the motor and 400 Wh battery.
Just 100 g (0.22 lb) heavier than the original Air yet tripling the performance, the Air S delivers up to 90 Nm of torque and 620 W of peak power, catapulting it into the realm of powerful mid‑drive motors built for demanding trail performance. That’s the same torque you’d expect from some of the strongest mid‑drive motors in modern electric mountain biking, yet in a package that’s still feather‑light.

Why it matters for lightweight e-bikes
As New Atlas recently pointed out, these motors are enabling super lightweight builds that previously weren’t possible: Bikes using the Air S, like the Thömus Lightrider E‑Max or Instinctiv’s Ocelot, tip the scales at barely 15 kg (33 lb), far lighter than typical full-suspension e‑MTBs, thanks largely to the slender motor and integrated battery design.
With torque now hitting 90 Nm, up from just that meager 30 Nm on the original, the Air S now delivers serious climbing power without the bulk. This brings light-assist bikes into full‑power territory, making acceleration and steep terrain feel effortless. Previously, ultra-lightweight e-bikes made serious compromises on power to achieve that level of near weightlessness. But now, they can actually compete on power, too.
Maxon’s unique split‑cylinder configuration also allows the motor to remain visually discreet. Combined with frame‑integrated batteries (400 Wh to start, with a 600 Wh option reportedly on the way), the system preserves clean lines and low weight. Many e-bikes sporting the motor simply won’t even look like e-bikes to the casual observer.
With the Air S, Maxon has struck a rare balance: ultralight design without compromise on torque. It catapults lightweight e-bikes into a new performance bracket, granting riders both agility and power. If you’ve long dreamed of an e-bike that feels like a mountain goat on the climb yet disappears under 16 kg, the Air S is probably your motor.
The trail-ready future is lighter, leaner, and looks ready to race uphill.

There you are, motoring along in your Volvo XC90 PHEV with the Pilot Assist engaged alongside a big 18-wheeler at a comfortable 70 mph cruise when the interstate starts to slowly sweep left. From the drivers’ seat, that semi on your right looks awfully close. As the steering wheel turns itself in your hand, you start to wonder if that truck’s a bit too close. The car isn’t doing anything wrong, but it’s too close for your comfort and you give the wheel a little nudge to hug the inside of the lane just a bit more.
These deeply personal preferences are tough to quantify, and highlight a simple fact about Advanced Driver Assistance Systems (ADAS) that the industry at-large hasn’t yet to come to terms with: when it comes to self-driving cars, one size does not fit all.
The Volvo experience I outlined above was very real, happening just as the wife and I were arguing about the relative merits of our very different choice in running shoes. She prefers the supportive, cushion-y ride of the HOKA Clifton 9s, which I’ve become convinced are The Devil™, preferring instead the zero-lift, no-cushion feel of my Xero Prio runners. The intervention with the Volvo interrupted that particular argument and started another. Namely, the one about why I had chosen that moment to “interfere” with the Pilot Assist.
“It was too close to that truck,” I explained. “Freaked me out.”

“That’s how I feel in the Honda,” she said. “I’m always afraid that it’s going to try and put me into oncoming traffic.”
That’s when the idea for this post came to me. Because, as a car brand, it’s really not possible to just say that your car has ADAS or doesn’t have ADAS in a binary sense. That’s because these systems are not just proprietary to a given brand, they can vary from vehicle-to-vehicle within that brand, and each one can have distinct lane centering behavior, steering feel, lane change aggressiveness, braking distances, timing for its hand-off warnings, and probably a bunch of other stuff that I haven’t even thought of depending on what kind of cameras, sensors, and software the specific vehicle you are in is equipped with.
It’s a bit of a mess, in other words.
Opinion: Honda Sensing gets it right
I first experienced Honda’s ADAS in 2014, driving a then-new CR-V between Chicago and Bay Harbor, Michigan for an Acura press drive. Even in its early generations, I was impressed with the way it handled stop-and-go traffic, the way it guided you through turns, but didn’t do the turning for you, and the speed and intensity it used in braking very much mirrored my own.
Last month, I had a chance to test out the 2025 Honda Civic Sport Touring Hybrid for a week on Cape Cod. I picked the car up at PreFlight Parking outside Boston Logan, jammed it with luggage, and immediately hit heavy traffic, where the Honda Sensing Low-Speed Follow function took me right back to 2014, ratatouille-style, when my experience in that car had led me to believe that self-driving cars were right around the corner.
In the decade-plus since experiencing that first autonomous Acura, I’ve had the chance to experience Ford BlueCruise, Tesla Autopilot and FSD, and Mercedes-Benz DRIVE PILOT. And all, interestingly enough, in and around the Circuit of the Americas in Austin at one time or another over my three years of hosting Electrify Expo events there.
Each different OEMs’ system had its strengths and quirks. I remember Mercedes DRIVE PILOT as impressively precise, even clinical. The Ford system faded into memory. I couldn’t tell you anything about it, which is probably high praise. The Tesla systems, though, stood out — but for all the wrong reasons. Lane changes came too quickly, it accelerated too late, and too aggressively, and I often found myself bracing for collisions that (in fairness) never came.
More than once in those years I’ve wondered if maybe I’d just got it wrong back in 2014. That the tech was so new, and I had been so wow’ed by it initially, that I had got swept up in the hype of self-driving cars … but that drive in my wife’s XC90, back-to-back as it was with the Civic Hybrid, showed me that wasn’t it. Instead, I just didn’t like the way those other cars drove. Just like I don’t like the way HOKAs feel. And, just like my wife isn’t wrong for liking her gross marshmallow shoes (probably), I’m not wrong for preferring a more restrained digital co-pilot.
It’s a matter of fit, not fact — and that’s going to be a tough sell.
Everyone but me is wrong
Classic Carlin bit.
As the great George Carlin once asked, “Have you ever noticed that anyone who is driving slower than you is an idiot, and anyone driving faster than you is a maniac?”
ADAS systems live squarely in that same subjective space occupied by other drivers. If the bots brake too hard, steer too sharply, or get too close to the car head before changing lanes, they might not be technically doing anything wrong, but they’re maniacs – and right now, there’s no real way to know how one car’s ADAS is going to behave until you’ve spent some significant time behind the wheel. Like, “Uh-oh. I bought a thing and I hate it,” amounts of time.
That’s a problem for both buyers and sellers (to say nothing of manufacturers and software developers), because why would you risk demonstrating a system that might scare someone? How do you sell “confidence” and “convenience” when what feels confident and convenient to one driver feels reckless to another, and milquetoast to a third?
Lucky for you guys, I have a solution.

That asterisk (*) is there because these are completely made up, imaginary values. They’re simply there to illustrate one way for manufacturers and dealers to share objective, quantifiable information about how their different ADAS systems behave. If it’s done right, it might help a car shopper get a better feel for how their next car might drive, and prevent them from spending their hard-earned cash on a car that drives like an idiot. Or a maniac.
That’s my take, anyway – what’s yours? Head down to the comments and let us know what values you’d like to see represented on an ADAS scorecard, and how much you’d be willing to base your next car buying decision on how it drives.
As for me, my X handle might be VolvoJo, but if I’m shopping for a car that’s going to drive me instead of the other way around, I might have to see if “HondaJo” is available.
