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.

Hyundai is recalling nearly 600,000 vehicles, including the Palisade and IONIQ EVs

Hyundai issued a recall for nearly 600,000 vehicles in the US, including the popular Palisade SUV and several IONIQ electric vehicles.

Hyundai Palisade and IONIQ EV recall details

In a notice to the National Highway Traffic Safety Administration (NHTSA) on September 12, Hyundai announced a recall of 568,580 2020-2025 model year Palisade vehicles.

The recall is due to faulty seat belt buckles in the front and rear, which may fail to latch. Although Hyundai expects only about 1% of the Palisade models actually have the defect, it’s issuing the recall out of an abundance of caution.

Hyundai said those with impacted vehicles may notice a lighter-than-normal “click” when fastening the seatbelt. You can bring it to a Hyundai dealer, where they will fix the seatbelt, free of charge.

Owner notification letters are expected to be mailed on November 10, 2025. You can contact Hyundai’s customer service at 1-855-371-9460 with any questions. Hyundai’s recall number is 283.

In a separate notice sent to the NHTSA on September 12, Hyundai issued another recall for 31,042 2023 – 2025 IONIQ 6 EV models because the charging port door panel could detach.

Again, Hyundai expects only about 1% of them to have the defect. Those impacted can bring their vehicle to a local Hyundai dealer, where they will fix the port, free of charge.

Owner notification letters will also go out on November 10. Hyundai’s recall number for the IONIQ 6 is 282. Owners can contact Hyundai’s customer service hotline (listed above) with any questions.

But, wait, that’s not all. Hyundai issued a third recall on September 12 for just eight 2025 IONIQ 5 models due to improperly tightened fasteners that could loosen over time. Dealers will replace the bolts, align the wheels, and even replace the tires if needed, free of charge.

If you own any of the recalled vehicles, you can contact Hyundai’s customer service or NHTSA hotline (1-888-327-4236) with questions. You can also visit NHTSA.gov for more information.

Hyundai’s recalls follow Toyota, which issued a recall for over 590,000 vehicles in the US. Between the two, a combined 1.1 million cars have been recalled.

Tesla loses another Optimus robot leader, and upsets TSLA stock gamblers

Tesla loses another Optimus robot leader, and upsets TSLA stock gamblers

Tesla has lost another leader of its Optimus humanoid robot program, which is upsetting those who bet on Tesla’s stock (TSLA), as CEO Elon Musk says most of Tesla’s value is tied to the robot.

Musk claims that 80% of Tesla’s future earnings would come from its humanoid robot, which he believes would bring in trillions of dollars and finally justify Tesla trading at more than 200 times earnings.

That’s been hard to believe considering the state of the Optimus program.

All of Tesla’s public demonstrations so far have involved remote control by humans, and the company has not been entirely forthcoming about that.

In June, Milan Kovac, the head of the Optimus program, left Tesla, just months after being promoted to senior vice-president by Musk.

Shortly after, we learned that Tesla was delaying production due to an unexpected redesign.

Now, we learn that another leader of the Optimus program has left Tesla: Ashish Kumar, who led Tesla’s Optimus AI team for the past two years.

Kumar received a phD in artificial intelligence from Berkeley in 2023 and quickly joined Tesla’s humanoid effort. He was believed to be leading the AI aspect of the program, while Kovac led the overall program, including robotics.

He announced his departure on X:

Kumar confirmed that he joined Meta’s AI team as a researcher. Meta has been aggressively poaching AI researchers over the last year, but Tesla has remained largely unaffected by this effort.

The Facebook owner has been reported to be offering substantial compensation packages worth hundreds of millions of dollars and even billions to AI researchers, but this hasn’t been confirmed.

Some Tesla shareholders were visibly upset by Kumar’s announcement and some quickly accused him of taking Meta’s money:

Kumar responded and claimed that Tesla was actually giving him a better deal than Meta:

Financial upside at Tesla was significantly larger. Tesla is known to compensate pretty well, way before Zuck made it cool. If I wanted to optimize for money, I would have stayed at Tesla.

It didn’t stop many Tesla sharehodlers to be mean to him for simply deciding to work on something else than Optimus:

Electrek’s Take

It will not come as a surprise to anyone here, but damn, the Tesla community is really becoming toxic.

This individual dedicated two years of his life working at Tesla. The only appropriate thing to say is: thanks for your hard work and good luck in your next endeavor.

The reason they are being so mean is that they believe Elon Musk’s lies that Optimus will justify Tesla’s insane valuation and become the most valuable company in the world; this guy’s departure challenges their view.

Why would he give up working on the most important product of all time and likely become a billionaire in the process? Maybe because these things won’t happen?

Controversial electric moto influencer 'Surronster' appears to have been arrested

It looks like electric motorcycle influencer Surronster has landed himself in trouble south of the border, based on an arrest video posted to his social media channels.

A heavily edited video posted on his Instagram page shows the controversial rider in handcuffs being led into a police vehicle by officers in Tijuana, Mexico. The reel appears to have been filmed by a companion in the influencer’s entourage. No additional context was provided in the post, and at the time of writing, details surrounding the arrest remain unclear.

The incident comes just two days after the influencer posted another update to his social media showing that he was being denied entry into Mexico with his Sur Ron electric off-road motorcycle loaded in the bed of his truck.

In the more recent clip, the Tijuana Municipal Police appear to be questioning him and an associate before handcuffing them both. An officer is seen starting to remove the influencer’s helmet, then the clip jumps to a shot of the influencer entering the back of the police truck, edited to avoid showing his unhelmeted face. Surronster has long concealed his identity, always being filmed while wearing a full-face dirt bike helmet.

Surronster has gained a large following online by pushing the limits of electric motorcycles – especially the Sur Ron Light Bee and similar lightweight electric dirt bikes. His content often shows him performing stunts, riding in traffic without a license plate, and usually on electric dirt bikes that are not street legal for use on public roads. His 1M+ following is comprised mainly of young male viewers in their teens and twenties, with many attempting to imitate the riders’ style and stunts. He has risen to become one of the leading influencers in the electric motorbike industry, all while promoting a rebellious image and racking up millions of views on social media.

That notoriety has earned him plenty of fans, but also a long line of critics. Many in the e-bike and e-moto community have called out the influencer for encouraging illegal and unsafe behavior that risks drawing increased regulation and public backlash against electric two-wheelers, not to mention the danger to young riders who may attempt to recreate his stunts. Others defend him as a thrill-seeking entertainer similar to traditional motorsport stunt riders.

A large proportion of his videos feature illegal riding activities, but his strict control over his anonymity has meant that he has effectively operated with impunity. But getting arrested in a foreign country is a serious matter, and it remains to be seen what charges – if any – he’ll face. At the time of publishing, the Tijuana Minicipal Police have not responded to a request for comment.
