As communities, cities, and states develop ambitious energy efficiency and decarbonization goals, energy storage is an increasingly critical component of our energy economy. Renewable energy sources like solar and wind are changing how we power our buildings, industries, and grid; however, they are intermittent ― we need continuous power even after the sun sets or the wind dies down. As such, energy storage is critical to ensuring continuous power and allows energy producers to take full advantage during times of overgeneration on sunny (or windy) days.
When it comes to short-duration energy storage, lithium-ion batteries are considered the front-runner, but batteries are not the whole story. Our buildings, businesses, industries, and grid need more storage, at lower cost, for longer durations, and at larger capacities than batteries can provide to displace fossil fuels for a sustainable future.
To meet this energy storage challenge, researchers at the National Renewable Energy Laboratory (NREL) are in the late stages of prototype testing a game-changing new thermal energy storage technology that uses inexpensive silica sand as a storage medium. Economic Long-Duration Electricity Storage by Using Low-Cost Thermal Energy Storage and High-Efficiency Power Cycle (ENDURING) is a reliable, cost-effective, and scalable solution that can be sited anywhere.
The ENDURING Mechanism: Storable, Electrically Heated Sand Delivers On-Demand Electricity
ENDURING uses electricity from surplus solar or wind to heat a thermal storage material — silica sand. Particles are fed through an array of electric resistive heating elements to heat them to 1,200°C (imagine pouring sand through a giant toaster). The heated particles are then gravity-fed into insulated concrete silos for thermal energy storage. The baseline system is designed for economical storage of up to a staggering 26,000 MWh of thermal energy. With modular design, storage capacity can be scaled up or down with relative ease.

When energy is needed, the hot particles are gravity-fed through a heat exchanger, heating and pressurizing a working gas inside to drive the turbomachinery and spin generators that create electricity for the grid. The system discharges during periods of high electricity demand and when limited solar photovoltaic or wind power are available, such as early in the morning and evening, during dinner preparation, and when TVs are on. Once discharged, the spent, cold particles are once again fed into insulated silos for storage until conditions (and economics) are appropriate again for charging.
How Hot Sand in a Silo Is Revolutionizing Energy Decarbonization
ENDURING offers several advantages relative to other electricity storage technologies.
As a storage medium, abundant silica sand is stable and inexpensive at $30‒$50/ton, and has a limited ecological impact both in extraction and end of life. For comparison, lithium-ion batteries have an exceptional energy storage density ― important for certain sectors such as transportation, where weight matters ― but it comes at a high cost. Particle thermal energy storage is a less energy dense form of storage, but is very inexpensive ($2‒$4 per kWh of thermal energy at a 900°C charge-to-discharge temperature difference). The energy storage system is safe because inert silica sand is used as storage media, making it an ideal candidate for massive, long-duration energy storage.
ENDURING systems have no particular siting constraints and can be located anywhere in the country. These systems may also be constructed using existing infrastructure from retired coal- and gas-fired power plants.
ENDURING technology can support the expansion of renewable energy generation across our country. Building these cost-effective particle thermal energy storage systems around the United States could help utilities to continue using solar and wind without running the risk of destabilizing the grid or needing to curtail renewable energy generation. Particle thermal energy storage will also provide energy reserves so our communities can better navigate through extended weather events, whether a week-long cold front or a summer heat wave.
Multiple Potential Economical Use Cases Support Decarbonization by 2050
The Biden Administration seeks to achieve a carbon-free power sector by 2035 and a net zero emissions economy by 2050. Zhiwen Ma, principal investigator of the ENDURING project, sees an important role for particle thermal energy storage in achieving these goals. “While decarbonization of electricity has a clear path, decarbonization of the whole economy ― which includes things like building heat and industrial processes ― is more challenging because natural gas is very cheap, making it hard to displace,” he said. “Decarbonizing industrial processes and building heat is very tough.”
Converting renewable electricity into heat is one way to decarbonize these sectors. Ma sees an opportunity for particle thermal energy storage to play a role in cost-effectively supplanting natural gas. By using a heat pump, one unit of electricity is transformed into two to three units of heat, which can be stored in the particle thermal energy storage system and then later delivered to the end user (depending on the coefficient of performance of the heat pump or the use of an emerging pumped thermal energy storage technology). These technologies can be used for building and industry process heating to replace coal or natural gas.
In addition to providing grid storage and building heat, ENDURING offers a steady source of heat for industrial and chemical processes that are otherwise incompatible with the intermittency associated with solar and wind power.
According to NREL researcher Patrick Davenport, the economic environment, decarbonization goals, and technology have aligned for particle thermal energy storage. “Sand and concrete silos with refractory insulation are very inexpensive materials that can lead to low-cost energy storage,” he said. “Traditional four-hour storage technologies don’t scale well to the grid or city scale. Now that we are in need of large-scale energy storage, this technology makes a lot of sense.”
Early Achievements and ENDURING Promise
The ENDURING project is seeing promising progress and early interest. The team recently won the American Society of Mechanical Engineers Advanced Energy Systems Division and Solar Energy Division 2021 First-Place Best Paper Award and several U.S. Department of Energy technology funding awards. Patents on concentrating solar power integration have been awarded, and several more are being filed.
The ENDURING prototype heaters and heat exchangers are currently undergoing testing in high-temperature conditions. If the prototype tasks are successful this fall, Ma is confident that ENDURING technology will offer great potential to support renewable integration for future carbon-free energy supply.
Ma is not the only one who sees promise: NREL and clean-energy technology firm Babcock & Wilcox have an exclusive intellectual property option agreement to license the ENDURING particle thermal energy storage technology. Babcock & Wilcox are among several industry and academic research partners that contributed to the ENDURING project, including General Electric, Allied Mineral Products, Worley, Purdue University, and Colorado School of Mines.
ALSET Auto doesn’t protect cars; it protects EVs. This year, the Tesla customization company expanded its services to include all EV owners and offers services such as tint, ceramic coatings, paint protection film (PPF), and colored wraps. As ALSET Auto’s business grows, the company is offering new franchise opportunities to help expand its services to EV owners in the US and Canada.

Founded by EV owners for EV owners
ALSET Auto was founded in Portland, Oregon in 2018 by Phil Bunting and Marcus Brown after they each purchased Teslas and were dissatisfied with their experience in their search for viable exterior protection options.
I called a half dozen shops in my area and got the same runaround. They loved to disparage Tesla’s soft paint, but no one wanted to give me a firm price for paint protection over the phone,
recalls ALSET CEO, Phil Bunting:
They all wanted me to bring my Tesla into their shop first, refused to provide a firm estimate over the phone, and declined to list their all-in prices on their website. I remember thinking, if I can build, price, and purchase a $100,000 Model X on my iPhone in five minutes, why should getting my Tesla protected be any different?
Thus, the idea for ALSET (Tesla spelled backward) was born. The company envisioned offering customers an experience similar to buying a Tesla, where the price is transparent, and there is no upselling, bait-and-switch tactics, or pricing gimmicks. Instead of selling Tesla owners on the fear of what could happen to their EV’s unprotected paint, ALSET set out to build a lasting connection with customers based on a shared passion for the cars they love.
Over the past five years, ALSET Auto has quickly become a leading provider of paint protection and personalization services. Operating in 15 markets across North America, ALSET has protected and personalized more than 7,000 EVs.
Aside from Cybertruck wraps, ALSET Auto’s three core services appeal to the broader market of owners who are looking to protect, preserve and enhance the look of their EVs. The company forged a partnership with XPEL Inc. to offer its customers a suite of best-in-class protective film and coating options, which include:
ALSET Auto offers a suite of options to protect, preserve and personalize your EV
Tesla Cybertruck wraps have quickly become a significant portion of ALSET Auto’s expanding business. The company offers the largest selection of colored PPF in the industry with more than 250 options in gloss, matte, metallic, and color shifting. The company is currently wrapping about 100 Cybertrucks per month, with several locations wrapping as many as five per week. Bunting elaborated:
The demand for colored paint protection film in recent years has surged because most EVs are offered in limited colors. Unlike flimsy vinyl wraps, colored PPF offer durable protection, self- healing properties and longer warranty coverage. It is the best of both worlds for protection and aesthetics. For Cybertrucks, we are finding that it’s a matter of when their owners will purchase wraps, not if.
The company has received nearly 1,000 five-star reviews for offering highly specialized customer service along with an industry-leading, lifetime warranty. In addition, ALSET services are CARFAX certified so that all upgrades appear on CARFAX reports to increase resale value and assist in insurance claims.
Paint Protection Film (PPF) – This durable self-healing film is offered in a clear or matte finish and is most commonly applied to the entire car or the front impact zones which include the full hood, fenders, bumper and mirror caps. PPF protects the vehicle’s paint from unsightly rock chips, scratches and abrasions. In many instances, scratches in the film can be removed with heat from the sun or blowdryer, or by using hot water.
Nano Ceramic Coatings – When fully cured, ceramic coatings are up to three times harder than factory clear coat. ALSET Auto’s full interior and exterior ceramic package uses four different ceramic formulas which are applied to the paint and trim, wheels, windshield, as well as the interior. While these coatings are not intended to prevent rock chips, they help protect from light scratches and swirls, environmental contaminants, and etching from bug guts and bird droppings. They also make your EV extremely shiny and hydrophobic, which makes washing and maintenance a breeze.
Ceramic Window Film – Available in a variety of shades, ceramic window tint offers unrivaled heat rejection as well as protection from harmful UVA and UVB rays. It also provides a sleeker look and enhanced security and privacy. EVs with ceramic window tint can expect to get more range from their battery due to lower cabin temps and less use of their EV’s air conditioning.
ALSET Auto also participates in XPEL’s OEM referral programs, which include Tesla and Rivian.
ALSET Auto plans to award 12 new franchises in 2025
After successfully opening corporate locations in Portland and Seattle, ALSET Auto launched the company’s first franchise in 2021 in Dallas, Texas. In doing so, ALSET Auto completed a rigorous franchise registration process with iFranchise Group, Inc., an industry-leading consultancy group that has worked with Massage Envy, Denny’s, Vitamin Shoppe, Shelf Genie and other name brands.
Since then, ALSET Auto has expanded to 15 locations with several more franchises currently in the pipeline.

“Great to see Tesla’s Robotaxi unveiled … including the Robovan. But why wait?” Those are the words of Oxa’s VP of Director Strategic Partnerships & Universal Vehicle Autonomy, Paul Reynolds, on LinkedIn – and it’s hard to argue against the idea that if a self-driving van is a good idea five years from now, it’s a good idea today.
And Oxa says it has a self driving van today that’s ready to deliver on that idea’s promise.
Oxa’s autonomous-capable hardware is designed to fit snugly on the outside of the popular Ford E-Transit commercial van without encroaching on the van’s interior. That means fleets will be able to integrate the self-driving vans into existing fleets without the need to redesign their existing upfit solutions – a critical piece of the overall puzzle for fleet managers.
That also means that the self-driving version of the Oxa-powered Ford E-Transit can be configured to do everything the conventional ICE Transits can do, and serve logistics (delivery van), trades (work van), and passenger/shuttle services (up to 10 seats in passenger E-Transit trim – which we don’t yet get here in the US).
“Making the Ford E-Transit available for autonomous operations is the next step on our journey to deliver safe, scalable, and sustainable autonomous solutions,” explains Gavin Jackson, CEO of Oxa. “This vehicle represents an important milestone in our mission to reshape the future of passenger transportation and logistics.”
The Oxa E-Tranist self driving van is equipped with a full suite of sensing equipment to “take in the road,” including high-definition cameras, lidar, and radar sensors. The Oxa hardware sends a full 360-degrees’ worth of perception and long-range detection to the system’s processors, enabling autonomous operation at electronically-limited speeds of up to 35 mph in mixed traffic. The Transit’s manual controls are fully preserved, too, enabling a seamless transition to human operation in adverse/edge case conditions.
Yamaha has announced to its dealers that it will be pulling its e-bikes out of the North American market at the end of this year. In the meantime, the brand says that it will offer sales of up to 60% off for its remaining inventory and continue to support its e-bikes already sold in the US for at least five more years.
Yamaha’s electric bikes have been well-received in global markets and have also received rave reviews in the US. However, the company’s higher prices make it harder to compete in the North American market, which is dominated by value-oriented models with significantly lower price points.
Yamaha’s various electric bikes designed for commuting, fitness, and mountain biking all feature higher-end components, which has resulted in the company competing more directly with premium bicycle shops. The company’s elaborate frames and in-house motors have added value to their models, yet have also contributed to a more premium price range.
Meanwhile, Yamaha hasn’t been immune to the same sales slowdown and overstocking issues that have plagued the e-bike industry over the last few years, as the company explained to its dealers in the letter seen below.
“Dear Yamaha eBike Dealer,
We want to thank you for your partnership and for your business in purchasing and retailing Yamaha eBikes, and for proudly representing the Yamaha brand. However, as you know, the combination of a post-COVID oversupply within the entire bicycle industry, coupled with a significant softening of the market, has resulted in a particularly challenging business environment where it is extremely difficult to achieve a sustainable business model. Given these market conditions, we regret to inform you that Yamaha has made the difficult decision to withdraw from the U.S. eBike business and cease wholesaling units effective the end of this year.
Yamaha Motor Corporation, U.S.A. (YMUS) entered the U.S. eBike market in 2018, and we have enjoyed the opportunity to partner with you these past six years to sell exciting, high-quality, all-road, mountain, and fitness/lifestyle eBikes.
We will continue to support your dealership in the sell down of your inventory by extending the current “Fan Promotion” program where customers may receive up to 60% off their purchase of a new Yamaha eBike. This “Fan Promotion” program will be offered on all units retailed and warranty registered through June 30, 2025. YMUS will continue to provide parts, service, and customer support in the United States both now and in support of our limited 5-year warranty.
Finally, we wish to express our sincere appreciation and gratitude to you and your staff for your dedication and support of the Yamaha eBike business.
Thank you for your understanding and support.”
