With declining technology costs and increasing renewable deployment, energy storage is poised to be a valuable resource on future power grids — but what is the total market potential for storage technologies, and what are the key drivers of cost-optimal deployment?

In the latest report from the Storage Futures Study (SFS), Economic Potential of Diurnal Storage in the U.S. Power Sector, NREL analysts Will Frazier, Wesley Cole, Paul Denholm, Scott Machen, and Nate Blair, describe significant market potential for utility-scale diurnal storage (up to 12 hours) in the U.S. power system through 2050. They found storage adds the most value to the grid and deployment increases when the power system allows storage to simultaneously provide multiple grid services and when there is greater solar photovoltaic (PV) penetration.

“We find significant market potential for diurnal energy storage across a variety of modeled scenarios, mostly occurring by 2030,” said Will Frazier, National Renewable Energy Laboratory (NREL) analyst and lead author of the report. “To realize cost-optimal storage deployment, the power system will need to allow storage to provide capacity and energy time-shifting grid services.”

The SFS — led by NREL and supported by the U.S. Department of Energy’s (DOE’s) Energy Storage Grand Challenge — is a multiyear research project to explore how advancing energy storage technologies could impact the deployment of utility-scale storage and adoption of distributed storage, including impacts to future power system infrastructure investment and operations.

Expanded Capabilities to Model Storage Potential

For this work, researchers added new capabilities to NREL’s Regional Energy Deployment System (ReEDS) capacity expansion model to accurately represent the value of diurnal battery energy storage when it is allowed to provide grid services — an inherently complex modeling challenge. Cost and performance metrics focus on Li-ion batteries because the technology has more market maturity than other emerging technologies. Because the value of storage depends greatly on timing, ReEDS simulated system operations every hour.

NREL researchers used ReEDS to model two sets of scenarios — one that allows storage to provide multiple grid services and one that restricts the services that storage can provide. All the scenarios use different cost and performance assumptions for storage, wind, solar PV, and natural gas to determine the key drivers of energy storage deployment.

Installed Storage Capacity Could Increase Five-Fold by 2050

Across all scenarios in the study, utility-scale diurnal energy storage deployment grows significantly through 2050, totaling over 125 gigawatts of installed capacity in the modest cost and performance assumptions — a more than five-fold increase from today’s total. Depending on cost and other variables, deployment could total as much as 680 gigawatts by 2050.

“These are game-changing numbers,” Frazier said. “Today we have 23 gigawatts of storage capacity, all of which is pumped-hydro.”

Initially, the new storage deployment is mostly shorter duration (up to 4 hours) and then progresses to longer durations (up to 12 hours) as deployment increases, mostly because longer-duration storage is currently more expensive. In 2030, annual deployment of battery storage ranges from 1 to 30 gigawatts across the scenarios. By 2050, annual deployment ranges from 7 to 77 gigawatts.

System Flexibility Key to Storage Deployment

To understand what could drive future grid-scale storage deployment, NREL modeled the techno-economic potential of storage when it is allowed to independently provide three grid services: capacity, energy time-shifting, and operating reserves.

  • Blue — Energy Time-Shifting & Operating Reserves (No Firm Capacity From Storage)
  • Black — Firm Capacity & Energy Time-Shifting (No Operating Reserves From Storage)
  • Green — Firm Capacity & Operating Reserves (No Energy Time-Shifting From Storage)

NREL found not allowing storage to provide firm capacity impacts future deployment the most, although not allowing firm capacity or energy time-shifting services can also substantially decrease potential deployment. Operating reserves, on the hand, do not drive the deployment of storage within the study because they find limited overall market potential for this service.

Storage and Solar Symbiosis

Multiple NREL studies have pointed to the symbiotic nature of solar and storage, and this study reinforces that relationship. More PV generation makes peak demand periods shorter and decreases how much energy capacity is needed from storage — thereby increasing the value of storage capacity and effectively decreasing the cost of storage by allowing shorter-duration batteries to be a competitive source of peaking capacity. NREL found over time the value of energy storage in providing peaking capacity increases as load grows and existing generators retire.

Solar PV generation also has a strong relationship with time-shifting services. More PV generation creates more volatile energy price profiles, increasing the potential of storage energy time-shifting. Like peaking capacity, the value of energy time-shifting grows over time with increased PV penetration.

Next Up in the Storage Futures Study

The SFS will continue to explore topics from the foundational report that outlines a visionary framework for the possible evolution of the stationary energy storage industry — and the power system as a whole.

The next report in the series will assess customer adoption potential of distributed diurnal storage for several future scenarios. The study will also include the larger impacts of storage deployment on power system evolution and operations.

Classic Jeep Grand Wagoneer gets a battery electric makeover [video]

Classic Jeep Grand Wagoneer gets a battery electric makeover [video]

Texas-based tuning firm Vigilante 4×4 is known for its wild, high-horsepower Jeep SJ Hemi restomods – but they’re more than just a hot rod shop. To prove it, they’ve developed a bespoke, all-electric skateboard chassis designed to turn the classic Jeep Grand Wagoneer into a modern, desirable electric SUV.

The scope of the Vigilante 4×4 electric chassis project is truly impressive. More than just a Jeep SJ frame with an electric drive train bolted in, the chassis is a completely fresh design that utilizes precise 3D scans of the original SJ Wagoneers, Grand Wagoneers, and J-Trucks to establish hard points, then fitted with low-slung battery packs to give the electric restomods superior weight balance, a lower center of gravity, and objectively improved ride and handling compared to its classic, ICE-powered forefathers.

The result is a purpose-built platform that delivers power to the wheels through a dual-motor system – one mounted in the front, and one at the rear – to provide a permanent, infinitely variable four-wheel drive system that offers both on-road performance and the kind of off-road capability that made the Grand Wagoneer famous in the first place.

“This isn’t a replacement for our Vigilante HEMI offerings,” reads the official copy. “It’s a total revisit of the Vigilante platform under electric power.”

The company emphasizes that its new chassis is still in the prototype stages. As such, there are no specs, there is no pricing, there are no range estimates. Despite it all, the response from Jeep enthusiasts has already been strong. “Keep in mind this is our first prototype,” a spokesperson said. “There’s still a lot of work to be done – but the journey has begun.”

Electrek’s Take


Electric SJ chassis; Vigilante 4×4.

Retro done wrong – think the Dodge Charger Daytona EV or VW ID.Buzz – is a disaster. Always. If that nostalgic tone is just a little bit off, the song doesn’t work. The heartstrings don’t pull. Done right, however, the siren song of nostalgia will have you putting a second mortgage on your house to put a Singer Porsche or ICON Bronco in your garage.

It’s too soon to tell what side of that line the Vigilante 4×4 Jeep SJ will eventually fall, but one thing (at least) is certain: it’s closer to the mark than that Wagoneer S.

EQORE bags .7M to bring smart storage to power-hungry factories

EQORE, a distributed battery storage startup based in Somerville, Massachusetts, has raised $1.7 million in seed funding to help industrial buildings tackle rising electricity costs. The round was oversubscribed and includes backing from the Massachusetts Clean Energy Center (MassCEC), Henry Ford III of Ford Motor Company, and Jonathan Kraft of The Kraft Group.

The timing couldn’t be more relevant. Data centers are booming, and that demand is slamming an already stressed grid. Big, utility-scale batteries help at the grid level, but they can’t fix the bottlenecks happening on local distribution networks. That’s where onsite storage steps in — storing energy when demand is low and discharging it when demand spikes, which helps stabilize costs for both the grid and the businesses using it.

MassCEC’s head of investments, Susan Stewart, said, “What excites us the most about EQORE’s technology is the dual impact: grid support and customer savings.” She noted that commercial and industrial buildings are ideal hosts for battery storage, but haven’t gotten much attention until now. “EQORE is closing that gap.”

Investor Randolph Mann highlighted what makes the company stand out: “By uniting advanced controls with high‑resolution metering and true end‑to‑end service, EQORE finally makes commercial behind-the-meter storage effortless and financially compelling for businesses.”

EQORE comes out of MIT’s Sandbox program and delta v accelerator and is currently part of the Harvard Climate Entrepreneurs Circle incubator. CEO and cofounder Valeriia Tyshchenko, a third‑generation engineer from Ukraine and MIT graduate, said the new funding will help the company scale alongside its existing revenue.

With the seed round closed, EQORE plans to grow its team and ramp up battery deployments at energy-intensive manufacturing facilities. The company doesn’t just install batteries; it operates them. Its autonomous software shifts when a facility uses power based on market conditions and utility incentives, reshaping load in real-time without disrupting operations.

Check out Hyundai's cool new off-road electric SUV concept [Images]

Hyundai took the sheets of its new off-road electric SUV, the Crater Concept, at the LA Auto Show. Here’s our first look at the compact off-roader.

Meet Hyundai’s new off-road SUV, the Crater Concept

We knew it was coming after Hyundai teased the off-road SUV earlier this week, hidden under a drape. Hyundai took the sheets off the Crater Concept at the LA Auto Show on Thursday, giving us our first real look at the rugged off-roader.

Hyundai refers to it as a compact off-road SUV that’s inspired by extreme events. The concept was brought to life at the Hyundai America Technical Center in Irvine, California.

The off-road SUV draws design elements from Hyundai’s Extra Rugged Terrain (XRT) models, such as the IONIQ 5 XRT, Santa Cruz XRT, and the new Pallisade XRT Pro.

“CRATER began with a question: ‘What does freedom look like?’ This vehicle stands as our answer,” Hyundai’s global design boss, SangYup Lee said.

The off-road SUV features Hyundai’s new Art of Steel design theme, first showcased on the THREE concept at the Munich Motor Show in September.

Hyundai said the design team was guided by one clear goal: To create a rugged and capable vehicle that’s designed to go anywhere. The Crater Concept embodies that vision with added wide skid plates, 33″ off-road tires, limb risers, rocker panels, and a roof platform.

Hyundai designed the interior for “tech-savvy adventure seekers,” with a singular design centered around a high-brow crash pad that stretches across the dashboard.

The concept also swaps the traditional infotainment setup for a head-up display that spans the entire front window, which Hyundai said includes a live rearview camera.

Hyundai’s off-roader includes a new Off-Road Controller for front and rear locking differentials, as well as a terrain selector with modes including Sand, Snow, and Mud. Other off-road features include downhill brake control, trailer brake control, a compass, and an altimeter.

Although Hyundai said it was electric, it didn’t reveal any further details about the powertrain. The off-road SUV could be a battery-electric or fuel-cell-electric vehicle.

Like the new Nexo, Hyundai’s hydrogen fuel cell vehicle, the concept features “HTWO” lamps exclusive to its FCEVs.

Earlier this week, the design team at Hyundai Design North America also introduced its new design and ideation studio codenamed “The Sandbox.” The creative design studio is set to serve as a global hub for future XRT vehicles and gear.
