200 - Long-Duration Energy Storage with Zinc Batteries: Insights from EOS Energy CEO Joe Mastrangelo

Insider's Guide to Energy

In this episode of the Insiders Guide to Energy podcast, hosts Chris Sass and Jeff McAulay welcome Joe Mastrangelo, CEO of EOS Energy Storage, to discuss the transformative potential of long-duration energy storage solutions. Focusing on EOS’s innovative zinc-based battery technology, Joe explains the advantages of a non-lithium battery system for applications that demand flexibility, scalability, and safety. He highlights how this eco-friendly, fire-resistant technology offers a promising alternative for sectors requiring durable, sustainable energy solutions, from utilities to industrial applications.

Joe shares EOS’s journey to establishing a resilient and primarily U.S.-based supply chain—a move that has not only driven growth but also strengthened the company’s position amidst global supply chain disruptions. By building in Pennsylvania’s Mon Valley, EOS has brought jobs back to an area once defined by manufacturing while creating a streamlined, secure production process. Joe emphasizes the importance of using widely available raw materials, which allows EOS to lower production costs while contributing to the U.S. economy and reducing dependency on foreign supply chains.

Listeners interested in renewable energy will appreciate Joe’s insights on the demand for long-duration storage, which he sees as essential for a sustainable energy grid. He discusses EOS’s growth strategy, including upcoming pilot projects and the critical role of customer trust, bankability, and partnerships in scaling new technologies. This episode offers a compelling look into how EOS Energy Storage is paving the way for a cleaner, more resilient energy infrastructure by overcoming financial, logistical, and technological challenges.
