Expanding battery storage
Battery storage systems have become increasingly popular for data center power needs, but that’s not the entire market. The International Energy Agency (IEA) says battery storage is currently the fastest-growing power technology, with 108 gigawatts of battery storage capacity deployed globally last year. That represented 40% growth versus 2024.
EOS expanded its production capacity with the start of commercial production at its second manufacturing line yesterday. Today’s announcement that it is entering the European market through a partnership with a German battery energy storage systems company has investors jumping into the stock.

The new partnership will supply customers across Germany, Austria, and Switzerland. That is a key market as long-duration energy storage needs grow as Germany phases out coal-fired generation and replaces it with renewable energy sources. But it’s not just Europe expanding renewable energy. Solar and wind are the fastest-growing energy sources in the U.S. as well, according to recent research from The Motley Fool.
EOS is still an early stage company, but with sales expected to more than double this year compared to 2025, investors should consider adding EOS Energy to a well-diversified energy portfolio.
