NREL Inventiveness Sets New Record for Patent Activity
For Greg Glatzmaier, the road between innovation and implementation runs along a dusty stretch of highway about a dozen miles south of Boulder City, Nevada, where his patented idea could solve an industry problem. The destination for his idea is Nevada Solar One, an outpost in the desert where 186,000 parabolic shaped mirrors tilt to capture the sun’s rays.

“When the plant first opened, there was nothing around it but open desert with mountains to the west and east,” said Glatzmaier, a senior engineer in the Thermal Energy Science and Technologies group at the National Renewable Energy Laboratory (NREL). “The only other landscape feature is a dry lakebed north of the plant.”
Since Nevada Solar One began operations in the summer of 2007, other utility-scale solar power plants have opened in that lakebed. Nevada Solar One is the only concentrating solar power (CSP) plant in the region, however, and the technology faces a unique set of challenges.
The CSP facility uses concentrated beams of sunlight to heat a fluid flowing through 20,000 tubes to as high as 752 degrees Fahrenheit. The process creates steam to spin a turbine that powers a generator and produces electricity. Over time, however, the heat transfer fluid begins to break down and form hydrogen, which reduces the effectiveness of the process. Tiny metal pellets in the tubes absorb the hydrogen, but after about seven years they become saturated and cannot be removed and replaced. Glatzmaier developed a method to address the hydrogen problem.
“To try to go in individually and address the situation for each tube is not really practical,” Glatzmaier said. “So, the method that I’ve developed, and what’s in that patent, and what this project has been all about, is to reduce and control the level of hydrogen that’s in the heat transfer fluid.”
NREL applied for a patent on Glatzmaier’s invention in the fall of 2017. The U.S. Patent and Trademark Office last May granted patent protection to what is simply called “Hydrogen sensing and separation.”
Laboratory Filed 188 Patent Applications
Glatzmaier’s patent was merely one of the 40 U.S. patents issued to NREL during fiscal 2020, a bump from the 32 issued during the prior fiscal year. Of the 269 disclosures filed with the laboratory’s Technology Transfer Office as the first step toward either patent or copyright protection, 153 fell in the category of a record of invention and 116 in the area of software.
“We continue to see strong engagement from researchers who submit their ideas for evaluation, with especially strong growth in software,” said Anne Miller, director of NREL’s Technology Transfer Office. “It’s great to see such growth because it tells us that the outreach to the lab to get people to report their innovations and work with us in getting them protected and deployed means that it’s working, that people know who to contact. Hopefully, it means that they have some confidence in our ability to be helpful and steer them in the right direction.”

NREL filed 188 patent applications in FY20, up from 124 the year before.
Lance Wheeler, a research scientist at NREL, has about a dozen patent applications in the pipeline tied to the discovery several years ago of a way to turn windows into solar cells. The technology relies on perovskite solar cells that enable the glass to darken and generate electricity, and also switch back to a clear pane. The most recent patent approved, for “Energy-harvesting chromogenic devices,” was granted in November, or almost four years after the provisional application was filed.
“It’s much different than writing a paper because you can write a paper and get it published within months,” said Wheeler, who shares credit on the patent with colleagues Joey Luther, Jeffrey Christians, and Joe Berry. “You’ll never get a patent awarded in months. It’s usually at least a year, and three is not crazy.”
Buildings across the United States account for nearly two-thirds of energy used, so the notion of using these “smart windows” to take advantage of sunlight could bring that energy consumption down.
The patents issued so far for Wheeler’s dynamic photovoltaic windows cover foundational aspects of the technology and sprang from the initial research. A series of patent applications followed.
“When you write the first patent application, you don’t know everything,” Wheeler said. “As you learn more and especially for very particular market needs, or what a product might look like, you learn what’s important and you continue to protect the things that are working. Then you make more discoveries, and you patent more things, but they’re all aligned in the same area.”
Perovskite Composition Earns Patent Protection
Alignment, as it turns out, is a key part of making perovskites most effective in capturing the sun’s energy. Unlike widely used silicon, which is a naturally occurring mineral, perovskites used in solar cells are grown through chemistry. The crystalline structure of perovskites has proven exceptionally efficient at converting sunlight to electricity.
NREL researchers have explored possible combinations for perovskite formulas to find the best. That work resulted in a patent issued in April 2020 for “Oriented perovskite crystals and methods for making the same.” The process begins with a small crystal that’s attached to another crystal and then another and on and on. The crystals are also oriented in the same direction. Kai Zhu, a senior scientist and one of the inventors, uses bricklaying as an analogy.
“You lay one layer down, you put one next to another, you align them perfectly,” he said. “You have to do this in order to build a very large wall. But if you have some randomness in it, your wall will collapse.”
The patent, which covers the composition of the perovskite, was issued to Zhu, Berry, and Donghoe Kim of NREL and to a scientist in Japan. NREL filed the patent application in 2017. Compared to a perovskite solar cell made of crystals allowed to grow randomly instead of in a specific orientation, the NREL-developed composition has been proven to have fewer defects and able to move charge carriers quickly. The result is a perovskite solar cell capable of reaching the highest efficiency.
“This represents the current best performing perovskite composition for the single-junction solar cell,” Zhu said.
Software Filings Reach New Record
NREL’s Technology Transfer Office received 116 software record (SWR) disclosures in fiscal 2020, establishing a new record and marking a big increase from 72 the prior year. The growth in submittals is partly due to more software being developed and authorized for free open-source release. One software record approved for closed-source licensing last year and now available for commercial users is the Electric Vehicle Infrastructure Projection tool, or EVI-Pro. A simplified, open-source version, known as EVI-Pro Lite, also has been released.
The core of EVI-Pro allows users to forecast the demand for electric vehicle charging infrastructure in a particular area. The predictive nature of the software also enables users to determine in advance how an influx of electric vehicles might affect the grid and energy demand. EVI-Pro relies on real-world information.
Eric Wood, the NREL researcher who oversaw the development of EVI-Pro, said it is not enough to simply consider how many charging stations were installed in an area previously and make an educated guess based on that information.
“That misses some key points,” he said. “The vehicle technology is evolving. The charging technology is evolving. And the behavior of individuals that own these vehicles is evolving.”
Early adopters of electric vehicles could charge them at home, in their garage. As the market expands, Wood said, people living in apartments or who have to park on the street need to have a place to plug in.
“The role of public charging infrastructure is going to continue to elevate as the market grows,” he said. “Continuing to develop the software with an eye on reflecting the latest situation in the market is one of the challenges that we face, so keeping EVI-Pro relevant and current is important.”
From the Laboratory to the Outside World
For Glatzmaier, the journey to see how well his invention could perform at isolating and removing hydrogen from the concentrating solar power plant was not a quick one. Grounded from flying because of the pandemic, last year he made four trips to the Nevada site by car. Each trip took about 13 hours one way.
Scientists typically keep close to their laboratory space, with companies able to license ideas that sprang from the inventive minds at NREL. Often, with license in hand, a company will conduct research using its own people. In Glatzmaier’s case, Nevada Solar One signed cooperative research and development agreements that have kept the scientist and company working closely together since 2015.
Glatzmaier initially planned to address the hydrogen buildup using two processes: one to measure the amount of the gas, and a second to extract it. Laboratory-scale tests showed his ideas would work, but he still expected some hesitation from company executives when it came time to trying out the devices on a much larger scale.
“I was thinking, they’re going to be very reluctant because companies tend to not want to make changes to their power plants once they are up and running,” he said. So he proposed installing the mechanism to only measure hydrogen buildup. Instead, the company wanted him to move ahead and tackle both problems at once. From the initial idea to installation has been a long road, but it does not end in Nevada.
Glatzmaier said 80 concentrating solar power plants exist around the world, and talks are in their final stages to license the technology for its use in these plants.

![Finance a new EV for less: EV deals with 0% interest this September [update]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2024/08/Polestar-first-electric-SUV-US-1.jpeg?resize=1200,628&quality=82&strip=all&ssl=1)
Lease deals get all the headlines, but 75% of new car buyers still finance their cars, indicating that they want to own their vehicles once the payments are done. If that sounds like you, and you’ve been holding out for relief from sky-high payments, a wave of new EVs are now available with 0% financing — making it one of the best months yet to buy a new EV.
UPDATE: two more sporty electric crossovers make the list!
Every month, Electrek readers looking for great deals on a new EV flock to our lease deal posts. Recently, however, the comments have been asking another crucial question: what about EV deals for the people who want to buy, instead of leas?
You asked, we listened. This roundup is for that 75% of new car buyers who choose to finance their cars instead of lease — so here’s a list of all the 0% financing deals on EVs you can get in September, 2025.
As I put this list together, I realized there were plenty of ways for me to present this information. In the end, I decided to present these deals in alphabetical order, by brand name (make). And, as for which deals are new this month? You’re just gonna have to check the list. Enjoy!
Acura ZDX
New for the 2024 model year, the Acura ZDX uses GM Ultium battery and drive technology, but the styling, interior, and infotainment are all Honda, delivering GM-level parts support with Honda-level fit, finish, and quality. Add in standard Apple CarPlay support, 0% financing for up to 72 months, and $7,500 customer cash through September 30th, and the ZDX becomes easily one of the best sporty crossover values on the market.
Chevy Equinox EV
With an impressive combination of affordability, practicality, and advanced features, the Chevy Equinox is a standout EV. And with an EPA-estimated range of up to 319 miles and a starting price under $35,000, it’s no wonder they’re flying off dealer lots.
For well-qualified buyers, Chevrolet is offering 0% APR financing for up to 60 months through GM Financial through September 30th. That offer can be paired with the $7,500 federal EV tax credit (which you can claim at the dealer), along with up to $1,250 in additional discounts for Costco members, depending on membership level.
Dodge Charger
Dodge is hoping that at least a few muscle car enthusiasts with some extra cash will find their way to a Dodge store and ask for the meanest, loudest, tire-shreddingest muscle car on the dealer’s lot without caring too much about what’s under the hood.
For them, Dodge has the new electric Charger with up to 670 battery-backed horsepower. And if you still owed money on the Hemi you just totaled, Dodge will help get the deal done on its latest retro-tastic ride with a $7,750 retail cash allowance or 0% financing for up to 72 months — and that’s before any dealer discounts.
Ford F-150 Lightning
America’s best-selling electric truck offers V2x technology, a nationwide dealer network, a universe of aftermarket accessories, and a look that blends into the crowd. This month, this proven pickup adds 0% interest financing for up to 72 months. Ford Pro customer can get access to advanced telematics and, in some cases, even get help sourcing additional grants and rebates, too.
Ford Mustang Mach-E
With a few early examples now well into six-digit miles with no signs of slowing down, it’s no wonder the first four-door, all-electric Ford Mustang is outselling its gas-powered rivals (by more than 2:1). For 2025, the Mach-E Mustangs offer more range than before (up to 320 miles), faster charging (by nearly 6 minutes to 80%), and even a hardcore rally version. With 0% financing available for up to 75 months in some markets, expect the car to have no trouble finding buyers through September 30th.
GMC Hummer EV
The biggest of GM’s Ultium-based EVs are seriously impressive machines, with shockingly quick acceleration, plus on-road handling that seems to defy the laws of physics once you understand that these are, essentially, medium-duty trucks. This month, GMC is doing its best to move out its existing inventory with 0% financing for well-qualified buyers plus $1,250 in discounts for select Costco members. So, if you’re a fan of heavy metal you’ll definitely want to stop by your local GMC dealer and give the Hummer EV a test drive.
GMC Sierra EV
In addition to offering a solid Powerwall alternative, these big Ultium-based EVs from GM’s “three letter bandit” commercial brand are just as impressive as their Hummer stablemates, but one-up the Hummers with heavy-duty towing prowess and the added capability of bidirectional charging baked in. And, like the Hummer, GMC is doing its best to move out its existing inventory of Denali and AT4 model Sierra EVs with 0% financing for well-qualified buyers plus $1,250 in discounts for select Costco members.
Honda Prologue
Like the Acura ZDX at the top of this list, the Honda Prologue was blends the excellent GM Ultium EV platform with Honda sensibilities and Apple CarPlay to create a winning combination. It’s no surprise that it’s one of the top-selling electric crossovers — and to move out as many as possible before the $7,500 federal tax credit goes away, Honda is offering 0% APR for up to 60 plus up to an additional $2,000 in Honda Loyalty or Conquest cash.
Hyundai IONIQ 6
The last of the streamliners, the IONIQ 6 has influences from Ferry Porsche and Raymond Loewy without looking like a copy of either. In addition to being a future classic, it’s efficient, comfortable, quick, offers up to 361 miles of range, can charge just about anywhere, and (now through the end of the month), can be financed with 0% interest for up to 48 months or $7,500 in customer bonus cash on all trims.
If you’re flexible on color, Hyundai dealers with “aged inventory” will give you an extra $1,000, for $8,500 total incentive dollars on your IONIQ 6.
Jeep Wagoneer S
The Jeep Wagoneer S is a slick, capable, street-oriented EV that’s been inexplicably saddled with a sloping roof and spoiler that eats away at the electric SUV’s ultimate utility (that’s the “U” part), but if you can get past that minor caveat, this first-ever battery-powered Jeep is ready to deliver. With $7,750 retail cash allowance or 0% financing for up to 72 months before dealer discounts through September 30th, the Wagoneer S might just be the best EV deal going.
Kia Niro EV
Kia is doing a phenomenal job moving its supercar-baiting EV6 and ultra-capable EV9 family trucksters, but the under-mentioned and underrated little Niro EV seems like it could use a little help. To that end, Kia is offering 0% interest financing or up to $7,500 customer cash on select examples of the little urban runabout now through September 30th.
Lexus RZ
Starting at “just” $55,175, the Lexus RZ promises up to 266 miles of EPA-rated range from a 72.8 kWh battery in the base RZ300e (and 224 from the top-shelf RZ450e). With up to 308 hp and over 195 lb-ft of instant, all-electric torque, the RZ promises to be one Lexus’ sportier rides in any trim.
This month, several Lexus dealers are advertising interest-free financing on select RZ models for up to 72 months. Check with your local Lexus dealer for more informatoin.
Nissan Ariya
I’ve already said that the Nissan Ariya didn’t get a fair shake. If you click that link, you’ll read about a car that offers solid driving dynamics, innovative interior design, and all the practicality that makes five-passenger crossovers the must-haves they’ve become for most families. With up to 289 miles of EPA-rated range, Tesla Supercharger access, and 0% interest from Nissan for up to 72 months or up to $10,000 Customer Cash (that’s not a typo) undecided EV buyers could do a lot worse than to give the Ariya a chance to win them over.
Polestar 3
Sleek, Scandinavian, and seriously quick, the Polestar 3 is the lovechild of Swedish brand Volvo and Chinese brand Geely’s billions. As such, it delivers both Scandinavian style and high-tech substance with dual-motor power, a minimalistic, luxurious cabin, and Android Auto baked right in. The Polestar 3 was designed to turn heads while keeping daily driving effortless, and through the month of September, it’s sure to turn even more heads with 0% financing for up to 72 months through Polestar Financial Services and a $10,000 Clean Vehicle Incentive in some markets.
Put it all together, and the Polestar 3 stands out as one of the most compelling premium EV SUV deals of the month.
Subaru Solterra
The first-ever electric Subaru had a rocky start (no pun intended), but this off-road-ready sibling of the Toyota bZ4X seems like a solid mid-size electric crossover with some outdoorsy vibes and left-leaning granola style that offers more than enough utility to carry your mountain bikes to the trail or your inflatables out to the pond. Add in 227 miles of range, some big discounts, and 0% financing for up to 72 months, and this should be a great month for electric Subaru fans to drive home in a new Solterra.
Volkswagen ID.4
One of the most popular legacy EVs both in the US and Europe, the ID.4 offers Volkswagen build quality and zippy around-town handling. Everyone I know who has one loves it, and VW dealers are getting aggressive with discounts, making this fast-charging, 291 mile EPA-rated range, 5-star safety rated EV a value proposition that’s tough to beat.
This month, get a Volkswagen ID.4 with 0% financing for up to 72 months or up to $5,000 customer cash. You’ll need to do some math to see which offer works best for you.

![This is it: the FIRST pure electric vehicle to wear a Lamborghini badge [video]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/09/lamborghini_pwc.jpg?resize=1200,628&quality=82&strip=all&ssl=1)
True to Lamborghini’s legacy of speed and excess, the first battery-electric vehicle to wear the raging bull is also the fastest of its kind. Only this time, the badge isn’t on a car — it’s on a personal watercraft. Meet the all-new Seabob SE63 jet sled.
Co-developed with the Italian supercar brand, the Lamborghini-badged Seabob SE63 features a more powerful jet propulsion system than any of the company’s existing personal jet sleds, and is fitted with a carbon fiber motor shaft as a further nod to the Italian luxury brand’s high-performance heritage.
Here’s the surprising thing, though: the new Seabob SE63 isn’t inspired by a specific road-going Lamborghini. Instead, it gets its name from the Tecnomar for Lamborghini 63 sport yacht built by the Italian Sea Group shipyards.
Tecnomar for Lamborghini 63
Why, yes – I will take just about any excuse to post pictures of sexy Italian super yachts in bright, vibrant colors. Thanks for asking!
But we’re not here for superyachts. We’re here for super sleds, and German PWC specialist Cayago set out to make this one, “most powerful Seabob ever.” As such, the SE63 is designed to be grab-and-go personal jet sled that delivers significantly higher speeds than its Seabob stablemates. In fact, its makers say it’s fast enough to keep up with sharks and dolphins.
The riding experience is not just ‘a bit faster’, but thrillingly intense and unrestrained. Acceleration off the start line delivers an immediate adrenaline rush. Thrust, agility, top speed: everything is designed for maximum performance and pure emotion.
The new SE63 backs up those claims with a 6.3 kW (~8.5 hp) electric motor. And, while that hardly makes it a supercar, in the world of ePWCs, it’s enough to make the SE63 a monster. The SE63 also features a bigger, more energy-dense battery than other Seabobs, a combination good for up to 60 minutes of go-fast, water-based fun.
Seabob SE63 Lamborghini
The SE63 can recharge its batteries with a standard power outlet in just 1.5 hours, and be back on the water for even more fun in the sun.
The Seabob SE63 made its debut earlier this week at the Cannes Yachting Festival. Production is set to begin in early 2026, meaning you’ll be able to get yours just in time for the summer 2026 beach season. Prices have yet to be announced – but, like any Lamborghini product, if you have to ask you probably can’t afford it.
Check out the world premier of the Seabob SE63 for Automobili Lamborghini (the sled’s official name) in the video, below, then let us know what you think of the brand’s first BEV in the comments.

Tesla influencers tried Elon Musk’s coast-to-coast self-driving, crashed before 60 miles
A duo of Tesla shareholder-influencers tried to complete Elon Musk’s coast-to-coast self-driving ride that he claimed Tesla would be able to do in 2017 and they crashed before making it about 60 miles.
In 2016, Elon Musk infamously said that Tesla would complete a fully self-driving coast-to-coast drive between Los Angeles and New York by the end of 2017.
The idea was to livestream or film a full unedited drive coast-to-coast with the vehicle driving itself at all times.
We are in 2025 and Tesla never made that drive.
Despite the many missed autonomous driving goals, many Tesla shareholders believe that the company is on the verge of delivering unsupervised self-driving following the rollout of its ‘Robotaxi’ fleet in Austin, which requires supervision from Tesla employees inside the vehicles, and improvements to its “Full Self-Driving” (FSD) systems inside consumer vehicles, which is still only a level 2 driver assist system that requires driver attention at all times as per Tesla.
Two of these Tesla shareholders and online influencers attempted to undertake a coast-to-coast drive between San Diego, CA, and Jacksonville, FL, in a Tesla Model Y equipped with the latest FSD software update.
They didn’t make it out of California without crashing into easily avoidable road debris that badly damaged the Tesla Model Y:
In the video, you can see that the driver doesn’t have his hands on the steering wheel. The passenger spots the debris way ahead of time. There was plenty of time to react, but the driver didn’t get his hands on the steering wheel until the last second.
In a follow-up video, the two Tesla influencers confirmed that the Model Y had a broken sway bar bracket and damaged suspension components. The vehicle is also throwing out a lot of warnings.
They made it about 2.5% of the planned trip on Tesla FSD v13.9 before crashing the vehicle.
Electrek’s Take
Tesla shareholders used to discuss this somewhat rationally back in the day, but now that Tesla’s EV business is in decline and the stock price depends entirely on the self-driving and robot promises, they no longer do.
I recall when Musk himself used to say that when you reach 99% self-driving, it is when the “march of the 9s” begins, and you must achieve 99.999999999% autonomy to have a truly useful self-driving system. He admitted that this is the most challenging part as the real-world is unpredictable and hard to simulate – throwing a lot of challenging scenario at you, such as debris on the road.
That’s where Tesla is right now. The hard part has just started. And there’s no telling how long it will take to get there. If someone is telling you that they know, they are lying. I don’t know. My best estimate is approximately 2-3 years and a new hardware suite.
However, competition, mainly Waymo, began its own “march of the 9s” about five years ago.
Tesla is still years behind, and something like this drive by these two Tesla influencers proves it.
I was actually in a similar accident in a Tesla Model 3 back in 2020. I rented a Model 3 on Turo for a trip to Las Vegas from Los Angeles.
I ended up driving over a blown-out truck tire in the middle of the road like this. I was Autopilot, but I don’t know if the car saw it. I definitely saw it, but it was a bit late as I was following a truck that just drove over it. I had probably less than 2 seconds to react. I applied the brakes, but my choices were driving into a ditch on the right or into a car in the left lane.
I managed to reduce the force of the impact with the braking, but the vehicle jumped a bit like in this video. There wasn’t really any damage to the front, but the bottom cover was flapping down. I taped it together at the next gas station and I was able to continue the trip without much issue.
However, after returning it to the Turo owner and having the suspension damage evaluated by Tesla, the repair job was estimated to be roughly $10,000. I wouldn’t be surprised if there’s a similar situation with this accident.
