The Battery Energy Storage System (BESS) industry has experienced remarkable growth in recent years, driven by the global shift toward renewable energy and the increasing need for reliable grid stability solutions.
Modern BESS achieves round-trip efficiencies of 86–94%, depending on chemistry and system architecture, making them one of the most efficient energy storage technologies available. The primary role of BESS is to store excess electricity—especially from renewables like solar and wind—and release it during peak demand or grid disturbances.
These systems use rechargeable battery technologies—primarily lithium-ion (87% global share), followed by flow batteries (7%), lead-based systems (4%), and emerging long-duration chemistries (2%). BESS units range from small residential systems under 10 kWh to utility-scale installations exceeding 500 MWh.
ESS INC. ESS Inc. designs and deploys eco-friendly iron flow batteries for long-term energy storage. Their systems are well-suited for commercial, utility, microgrid, and off-grid use, providing reliable and flexible energy solutions. Since 2011, ESS has focused on promoting clean energy.
