An AI data center boom is fueling Redwood’s energy storage business

Redwood Materials' energy storage unit is rapidly growing amid an AI data center boom. The company expanded its R&D lab to 55,000 square feet, supported by a $425 million investment led by Google and Nvidia. This growth is driven by a surge in demand for reliable electricity to power AI data centers, as existing grid connections face long delays. Redwood leverages used EV batteries, aiming to support substantial energy needs in the sector.

Key Points

• Redwood Materials did not have an energy storage business a year ago but has grown rapidly since then.
• The R&D lab in San Francisco expanded four-fold and employs nearly 100 people.
• A $425 million Series E funding round, including new investor Google and existing backer Nvidia, is financing this expansion.
• Redwood's energy storage system supports AI data centers and renewable energy projects.
• There is a massive demand for data centers driven by AI advancements, causing energy supply challenges.
• The company uses old EV batteries for energy storage, with a system that generates 12 MW of power and has 63 MWh capacity.
• Future projects aim to cater to hyperscalers with energy storage capacities in the hundreds of megawatt hours.

Relevance

• The expansion aligns with the acceleration of AI and cloud computing, highlighting the importance of energy reliability in tech.
• In 2025, energy storage and management are key trends as AI's demand for data center infrastructure grows.
• Redwood's focus on circular supply chains and recycling reflects broader sustainability trends in technology.

Redwood Materials is capitalizing on the AI data center boom by diversifying into energy storage, addressing the urgent need for reliable power with innovative solutions, like using retired EV batteries, thereby positioning itself as a vital player in the evolving tech landscape.
