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.

SpaceX to launch Starlink V2 satellites on Starship starting 2027
The update was shared by SpaceX President Gwynne Shotwell and Starlink Vice President Mike Nicolls.
SpaceX is looking to start launching its next-generation Starlink V2 satellites in mid-2027 using Starship.
The update was shared by SpaceX President Gwynne Shotwell and Starlink Vice President Mike Nicolls during remarks at Mobile World Congress (MWC) in Barcelona, Spain.
“With Starship, we’ll be able to deploy the constellation very quickly,” Nicolls stated. “Our goal is to deploy a constellation capable of providing global and contiguous coverage within six months, and that’s roughly 1,200 satellites.”
Nicolls added that once Starship is operational, it will be capable of launching approximately 50 of the larger, more powerful Starlink satellites at a time, as noted in a Bloomberg News report.
The initial deployment of roughly 1,200 next-generation satellites is intended to establish global and contiguous coverage. After that phase, SpaceX plans to continue expanding the system to reach “truly global coverage, including the polar regions,” Nicolls said.
Currently, all Starlink satellites are launched on SpaceX’s Falcon 9 rocket. The next-generation fleet will rely on Starship, which remains in development following a series of test flights in 2025. SpaceX is targeting its next Starship test flight, featuring an upgraded version of the rocket, as soon as this month.
Starlink is currently the largest satellite network in orbit, with nearly 10,000 satellites deployed. Bloomberg Intelligence estimates the business could generate approximately $9 billion in revenue for SpaceX in 2026.
Nicolls also confirmed that SpaceX is rebranding its direct-to-cell service as Starlink Mobile.
The service currently operates with 650 satellites capable of connecting directly to smartphones and has approximately 10 million monthly active users. SpaceX expects that figure to exceed 25 million monthly active users by the end of 2026.

Elon Musk’s xAI and X to pay off $17.5B debt in full: report
The update was shared initially in a report from Bloomberg News, which cited people reportedly familiar with the matter.
Elon Musk’s social platform X and artificial intelligence startup xAI are reportedly preparing to repay approximately $17.5 billion in outstanding debt in full.
The update was shared initially in a report from Bloomberg News, which cited people reportedly familiar with the matter.
Morgan Stanley, which arranged the debt financing for both companies, has reportedly informed existing lenders that X and xAI plan to pay back the full amount of the $17.5 billion debt. Bloomberg’s sources did not disclose where the capital for the repayment would be coming from.
X, formerly known as Twitter, assumed roughly $12.5 billion in debt during Musk’s acquisition of the company. xAI separately borrowed about $5 billion through bonds and loans last June. The two firms merged last year under xAI Holdings.
Bloomberg noted that portions of the debt are relatively recent and may carry early repayment penalties. xAI’s $3 billion in high-yield bonds are expected to be redeemed at 117 cents on the dollar, reflecting a premium since the debt was expected to stay outstanding for at least two years.
X has been servicing tens of millions of dollars in monthly debt payments, while xAI has reportedly been burning approximately $1 billion in cash per month as it invests heavily in data centers, chips, and AI talent. That being said, xAI also concluded a funding round in January, where it raised $20 billion of new equity.
The repayment plans come as Musk consolidates several of his businesses. SpaceX recently acquired xAI, making it a subsidiary as the company explores plans for space-based data centers. The combined entity has been valued at approximately $1.25 trillion.
Bloomberg previously reported that SpaceX is targeting a confidential IPO filing as soon as this month, potentially positioning the private space firm for a public listing later this year. Representatives for Morgan Stanley declined to comment, and X and xAI did not immediately respond to requests for comment.

Tesla Giga Berlin head calls out Handelsblatt’s claimed 2025 production figures
Andre Thierig, Senior Director of Manufacturing at Giga Berlin, published a detailed post on LinkedIn challenging several points made in the publication’s coverage of the Grünheide facility.
Tesla Gigafactory Berlin’s plant manager has publicly pushed back against recent reporting by German business publication Handelsblatt, which cited reportedly erroneous data about the factory’s production figures and financial performance.
Andre Thierig, Senior Director of Manufacturing at Giga Berlin, published a detailed post on LinkedIn challenging several points made in the publication’s coverage of the Grünheide facility.
In his LinkedIn post, Thierig called out Handelsblatt’s claim that 149,000 Model Y vehicles were produced at Giga Berlin in 2025. He noted that “the article is simply filled from front to back with false information and claims!
“I have to set the record straight here! In the last article about Tesla in Grünheide, the Handelsblatt speaks e.g. of 149,000 Model Ys built in 2025. WRONG!
“In 2025, we again produced over 200,000 vehicles. And this despite the fact that we stopped production in Q1 for the changeover to the new Model Y and then ramped it up again to 5,000 units per week over several weeks,” Thierig wrote.
He added that production increased each quarter in 2025 compared to the prior quarter and stated that more than 700,000 Model Y units have been produced at Grünheide since manufacturing began in 2022. For the first quarter of 2026, he stated that the factory is planning another production increase compared to the fourth quarter of 2025.
Thierig also questioned Handelsblatt’s reported 0.74% profit margin, writing that how the publication calculated the figure “remains reserved for their secret ‘calculation skills.’”
Beyond production data, Thierig highlighted Tesla’s broader footprint in Germany, stating that the company has invested more than €5 billion in Grünheide since 2020 and created nearly 11,000 permanent, above-tariff jobs. He added that Tesla is currently investing nearly €100 million into battery cell production at the site, which is expected to generate several hundred additional positions.
In a follow-up comment, Thierig noted that he did communicate with the publication’s editor-in-chief in an effort to “start fresh,” but he was informed that Handelsblatt’s current approach works just fine.
“Last year, I spoke to a representative of the Handelsblatt editor-in-chief and suggested that we “start anew” again. Handelsblatt turned down this offer on the grounds that their current approach works well for them,” Thierig noted.
Sönke Iwersen, Head of Investigative Research at Handelsblatt, responded to Thierig’s post, stating that the newspaper’s figures were based on Tesla’s own annual financial statements for the Grünheide entity.
He cited reported 2024 revenue of €7.68 billion, operating profit of €156.8 million, and net income after taxes of €55.6 million. Iwersen also referenced prior public comments from Elon Musk about Cybertruck demand, noting the gap between reported pre-orders and subsequent annual sales figures.
He also stated that the works council election eligibility figures Giga Berlin had dropped to 10,703 employees today from 12,415 two years ago.
“As far as production figures are concerned, these are figures from the data service provider Inovev. This is also stated in the article. Please compare this with Elon Musk’s information on demand for the Cybertruck. According to Musk, there were one million pre-orders. In the first year, 39,000 units were sold, in the second year 20,000. How can this be explained? With a million pre-orders?
“You yourself have repeatedly pointed out in recent months that no jobs would be cut in Grünheide because Tesla is different from the competition. Now a new works council is being elected in Grünheide. 10,703 people are eligible to vote. Two years ago, 12,415 people were eligible to vote. So there were exactly 1712 fewer from 2024 to 2026,” Iwersen wrote.
