Redwood Materials Shifts from Battery Recycling to Powering AI Data Centers

The tech sector is buzzing with rapid transformation, especially with the huge expansion of AI data centers. This has opened up exciting new growth opportunities for Redwood Materials, which has quickly emerged as a powerful player in the energy storage market in less than a year. This shift is all thanks to the soaring demand for reliable, quickly deployable electricity sources to power our growing digital infrastructure. Founded in 2017 by JB Straubel, a former CTO at Tesla, the company initially focused on recycling batteries from electric vehicles and consumer electronics. Over time, they expanded into producing battery materials. Now, they've taken another big step, launching a specialized unit called Redwood Energy in June 2025 to provide energy storage solutions, with a primary focus on meeting the needs of data centers. In just one year, energy storage has become the fastest-growing part of the company! To support this expansion, Redwood has quadrupled its R&D center in San Francisco to about 55,000 square feet. They now have a team of nearly 100 employees working hard to develop and integrate complete energy storage systems, covering everything from hardware and software to power electronics. This new direction comes at a crucial time when data center developers are facing increasing challenges getting electricity connections from public grids. Sometimes, these procedures can take over five years! With global competition in AI heating up, there's a huge demand for independent power solutions that can be deployed quickly to keep these centers running. Redwood's first real project in this area was with Crusoe, where they installed a system using used electric vehicle batteries. This system provides 12 megawatts of power and has a capacity of 63 megawatt-hours, powering a modular data center. The company is now working on even bigger projects, including systems with capacities of hundreds of megawatt-hours, plus projects in development that will reach several gigawatt-hours to meet the needs of major cloud computing companies. To fuel this expansion, the company secured a Series E funding round of $425 million. Prominent investors like Google participated, alongside existing supporters such as Nvidia. This really highlights the growing importance of energy storage as a key component in the AI ecosystem and digital infrastructure. This strategic shift reflects a new reality in the tech sector: the challenge isn't just building data centers anymore, it's also about providing enough power to run them. With the massive increase in electricity consumption from AI applications, reusing electric vehicle batteries is emerging as a practical and fast option to boost electricity supplies. By taking this path, Redwood Materials is reshaping its role in the market. They're transforming from a specialized recycling company into a major provider of energy solutions for digital infrastructure. They're cleverly leveraging two big trends: the move towards clean energy and the rapid global growth in demand for advanced computing.
