🗞️ Driving the news: Aspen Aerogels has secured a $670.6 million loan commitment from the U.S. Department of Energy to build a new factory in Georgia, producing super-light materials that improve EV battery safety by helping prevent fires
Automakers such as General Motors, Toyota, and Audi already use these materials

🔭 The context: Battery fires, while rare, pose a significant safety challenge for electric vehicles (EVs) due to the risk of thermal runaway
Aspen’s aerogel materials act as thermal barriers between battery cells, slowing or isolating fire propagation to give drivers time to exit safely

🌍 Why it matters for the planet: Improving battery safety is critical for accelerating EV adoption, reducing reliance on fossil fuels, and cutting greenhouse gas emissions in the transport sector

⏭️ What's next: Once the new factory reaches full capacity, it could supply materials for over two million EVs annually, significantly enhancing battery safety standards across the industry

💬 One quote: "I think the goal is to really make sure that they’re helping to achieve critical battery safety goals that we all share" — Jigar Shah, Director of the DOE Loan Programs Office

📈 One stat: Aspen’s thermal barriers cost between $300 and $1,000 per EV, depending on the vehicle
