Transitioning to renewable energy requires a multi-faceted approach, and power storage from sources such as solar and wind energy will play an increasingly important role in that playbook in the future. To tackle this problem, former Northvolt and Tesla workers have joined forces to focus on the scalability of battery production with the new company Peak Energy.
Peak Energy aims to mass-produce giant battery storage systems for renewable sources such as wind and solar (via CNBC). CEO and Founder Landon Mossburg formerly worked at Tesla and went on to work as an executive at Northvolt before founding Peak Energy earlier this year.
The company plans to scale a more affordable battery chemistry than the lithium-ion batteries used in Tesla’s Megapacks, instead hoping to produce large-scale battery systems with lower-density, lower-cost sodium-ion technology.
Since the company plans to mass-scale an existing product, Peak Energy President and COO Cameron Dales notes that they don’t consider the company a startup, although it only started in June. Interestingly, Peak Energy is looking to partner with a technology company specializing in battery tech, but specifically one that doesn’t yet have the ability to scale its products.
“A normal Silicon Valley startup is 10 years in the lab, come up with a better mousetrap and go to market. We’re completely the opposite,” Dales told CNBC in an interview.
The company plans to make individual sodium-ion battery cells, roughly the size of a loaf of bread, according to Dales. These cells will then be used together to make larger modules about the size of a filing cabinet. These filing cabinet modules could be deployed at solar or wind farms at volumes of 50-100 per order.

With 100 blocks, Mossburg explains, the battery system is expected to be able to power as many as 62,500 homes for up to four hours.
He also thinks that the company’s battery systems could cost around half the cost of a Tesla Megapack’s $1.3 million before installation, though it’s still too early for the company to have a price on its products.
“In the battery market it turns out the rarest commodity is not the technology — there are many excellent ideas out there at academic labs and startups — but rather the ability to scale to manufacturing,” Mossburg said. “The difficulty of manufacturing scale up is one of the reasons you see so many ‘breakthrough battery technology’ announcements but very very few companies who actually reach market.”
The company has also announced a $10 million funding round led by Eclipse Ventures’ Greg Reichow, a former Tesla executive who was in charge of battery, motor and electronics manufacturing before going on to lead global manufacturing. Crucially, Dales points out to CNBC that Reichow also led the development of Tesla’s Giga Nevada battery factory with partner Panasonic, which he considers the first mass-scale battery factory in the world.
TDK Ventures, owned by Japanese multinational electronics manufacturer TDK, will also join the funding round.
“The number one issue we face as it relates to expanding renewable energy sources is storage,” Reichow said. “This problem must be solved, but the existing approaches using lithium-ion and other technologies are not yet at a price point that enables the kind of scaling that society needs across sectors.”
The U.S. Energy Information Administration forecasts battery storage capacity to increase from just 9 gigawatts last year to as much as 49 GW by 2030 before jumping to 247 GW in 2050. This projection shows demand for mass-scale battery storage will continue to grow, especially as transportation and other sectors shift toward renewable energy sources.
Peak Energy currently hopes to produce “double digit gigawatt” amounts of battery cells by 2030, set to be used for its own battery systems and other applications. According to Mossburg, building a battery factory will take between $50 million and $100 million per GW. He also says a 30 GW factory would have between 2,000 and 3,000 workers, requiring a 1-2 million square-foot space.
Mossburg has experience scaling battery production at Northvolt, founded by former Tesla Global Head of Sourcing and Supply Chain Peter Carlsson, who worked for the automaker from 2011-2015. By the time Mossburg left Northvolt, the company had grown to employ 4,000 people from just 300 only 18 months prior.
″We’re running a playbook which I and the rest of the executive team initially demonstrated and deployed at Northvolt,” Mossburg said.

Tesla’s NHTSA probe is already on its way to being resolved
The problem the NHTSA had with Tesla’s reporting is already on its way to being resolved, as the agency and the company have been in communication.

Tesla is being probed by the National Highway Traffic Safety Administration (NHTSA) for not reporting accidents in a timely manner, the agency said on Thursday.
It is already well on its way to being resolved, the agency said.
The agency’s Office of Defects Investigation (ODI) identified numerous instances in which Tesla reported crashes that “occurred several months or more before the dates of the reports.”
The Standing General Order in place by the agency requires crash reports to be submitted within five days of Tesla receiving the notice of an accident.
The investigation states Tesla submitted crashes in one of two ways:
“Many of the reports were submitted as part of a single batch, while others were submitted on a rolling basis.”
The problem the NHTSA had with Tesla’s reporting is already on its way to being resolved, as the agency and the company have been in communication.
Tesla has already been in contact with the agency’s ODI and stated that the timing of the reports was an issue with its data collection. The issue has been resolved, Tesla told them.
The NHTSA said the initiation of the probe against Tesla is a “standard process for reviewing compliance with legal requirements, to evaluate the cause of potential delays in reporting, the scope of any such delays, and the mitigations that Tesla has developed to address them.”
It is the latest NHTSA probe into Tesla, as it has also been investigating the company for accidents during Full Self-Driving operation in reduced visibility conditions.
The agency also sought information on the rollout of Robotaxi a few months ago, and how Tesla planned to handle low-visibility conditions in its driverless ride-hailing service.
The NHTSA was interested in knowing how Tesla planned to assess the ability of FSD’s engineering controls, whether any other similar FSD crashes had occurred in low visibility, and if modifications to FSD software would impact its performance in these conditions.

Tesla rolls out minor but significant improvement to Robotaxi service
As per Tesla, Robotaxis will now arrive at their pickup locations with their doors locked.

Tesla has rolled out a minor but significant improvement to its Robotaxi service. The update was shared by the Tesla community on social media platforms such as X.
New Robotaxi App update
As observed by the electric vehicle community on social media, Tesla has started rolling out the Robotaxi App’s Version 25.8.5 (6074) to users. The update seems to be quite minor, though Tesla mentioned something quite notable the update’s “What to Test” section.
As per Tesla, Robotaxis will now arrive at their pickup locations with their doors locked. Customers would not need to unlock the Robotaxis manually, however, as the vehicles would automatically unlock as they approach the car. “You ride now arrives locked and will automatically unlock as you walk up. Just ensure your app has Bluetooth access enabled,” Tesla wrote.
While this update is minor, it does improve the safety of the vehicles themselves. It also provides another layer of convenience for users of the driverless ride-hailing service. The fact that Tesla is already refining the Robotaxi App’s features this early bodes well for the program. It suggests, if any, that the service will already be fairly refined when it starts being opened to more users.
Robotaxi praised for its safety
Tesla is following a deliberate and cautious rollout strategy for its Robotaxi rollout, though early reviews of the system have been quite positive. Some reviewers have also dubbed Tesla’s Robotaxi service as a safer alternative to more conventional ride-hailing services such as Uber.
This was highlighted by auto reviewer Scotty Reiss in a post on A Girl’s Guide to Cars.
“I like the personal safety factor. No driver to threaten or harass you. You control the locking and unlocking of the car. You can change the pickup location at any time. The car will wait for you. You can call the support desk if you need help. You can change your destination if the drop-off area seems sketchy. All of it together makes me feel safer getting a car home from the airport at midnight or into the city after dark, and I definitely feel safer having my daughters take a self-driving rideshare when they go out to meet friends for dinner,” Reiss wrote in her post.

Tesla China VP confirms Model Y L first deliveries in September
The first deliveries of the extended wheelbase all-electric family car are expected to start in just a few weeks.

Tesla China Vice President Grace Tao has subtly confirmed the recently released Model Y L’s first deliveries. As per the executive, the first deliveries of the extended wheelbase all-electric family car are expected to start in just a few weeks.
Model Y L estimated delivery date
While the standard Tesla Model Y Rear Wheel Drive (RWD) and All Wheel Drive (AWD) are listed with an estimated delivery date of 1-3 weeks, the electric vehicle maker simply listed the Model Y L with an estimated delivery date of “September 2025.” This date was reiterated by VP Grace Tao in a post on Weibo.
“Prospective Model Y L owners are welcome to post their orders in the comment section. This Sunday, August 24th, at midnight, 10 friends will be drawn to receive Tesla peripherals… Tesla cars are fun to drive alone, whether you have children or how many children, this car can meet all your needs. We will deliver in September and wait for you to get in the car,” Tao wrote.
Model Y delivery speculations
While Grace Tao’s Weibo post confirmed that the Model Y L’s first customer deliveries will indeed be held within September, some industry watchers have estimated that the extended wheelbase vehicle will start deliveries in about three weeks. This suggests that the first Model Y L customer deliveries could start around September 11 in China. This date would be quite impressive considering that the vehicle was released just a few days ago.
The Tesla Model Y has so far been a hit among followers of the company, so much so that fans in countries like the United States have expressed their intention to purchase the vehicle, which starts at just RMB 339,000 ($47,180). Unfortunately, Tesla CEO Elon Musk has stated that the Model Y L will not start production in the United States until the end of 2026. He also noted that the vehicle might not ever make it to the U.S., due to the advent of self-driving cars in the country.
