As the demand for efficient and scalable energy storage continues to grow, Fluence Energy Inc. has unveiled Smartstack, an advanced storage platform designed to tackle industry challenges head-on. This latest innovation offers enhanced energy density, streamlined logistics, and greater flexibility, making it a pivotal development in grid-scale storage solutions.

Smartstack modular battery

Fluence Energy Inc. has announced the launch of Smartstack, a response to the growing demand for efficient and flexible energy storage solutions in the face of increasing grid instability and renewable energy expansion., a new high-density, AC-based energy storage platform designed to enhance grid-scale storage capabilities. The company plans to begin deliveries in late 2025, with the system addressing key industry challenges such as efficiency, transport logistics, and land use constraints.

With the growing demand for high-density energy storage solutions, one of Smartstack’s standout features is its modular design, which increases site density, delivering up to 7.5 MWh per system—about 30% more energy density than current AC-based solutions. The system’s split-unit architecture aims to simplify transportation and installation while reducing supply chain risks. This approach could make storage projects viable in locations that were previously unsuitable.

A Modular, Scalable Future

The Smartstack platform is built around two core components: the Smart Skid, which houses power control, cooling, and monitoring technology, and battery pods, which sit atop the skid and support cells from multiple manufacturers. The flexibility of Smartstack allows for storage durations ranging from 2 to 8 hours, catering to diverse market needs.

Fluence has also integrated AI-driven optimization, enabling the system to autonomously manage energy flow and achieve up to 99% efficiency under long-term service agreements. The modular design further supports regional manufacturing, helping to reduce geopolitical risks and improve supply chain resilience.

Safety remains a major focus, with multi-layered fire protection systems and real-time monitoring aimed at minimizing downtime and enhancing operational security. Fluence, which has deployed over 37.7 GWh of storage globally, continues to position itself as a key player in advancing renewable energy integration.
