Stryten to Expand Energy Storage Capacity to 24 GW/yr

Stryten Energy

Stryten Energy expands U.S. battery manufacturing to 24 GW/yr, strengthening grid storage and national defense readiness.

New Capacity Strengthens U.S. Energy Independence

Stryten Energy will expand its domestic battery manufacturing to 24 GW/yr, reinforcing U.S. energy resilience for critical sectors. The company is adding 10 GW/yr of new energy storage production, bringing total capacity across multiple states. These include existing facilities in Pennsylvania, New York, Indiana, Missouri, Wisconsin, and a new lithium battery plant in Georgia.

The move comes as the U.S. government pushes for greater localization of energy storage supply chains for national security and energy transition goals.

Applications Span Defense, Grid Storage, and Industry

Stryten batteries serve military, government, data centers, automotive, material handling, and grid storage sectors. The capacity boost ensures supply for high-priority applications, including mission-critical defense and infrastructure operations. This investment aligns with ongoing public-private energy security initiatives and increases resilience across the U.S. energy ecosystem.

The expansion is supported by the advanced manufacturing production tax credit, helping incentivize capital investments in domestic clean tech.

The Metalnomist Commentary

Stryten’s expansion confirms that U.S. battery capacity growth is no longer driven solely by EV demand. National security, grid stability, and industrial continuity now anchor the battery sector’s relevance — and future growth path.

Largo and Stryten Launch Storion Energy to Boost U.S. Vanadium Redox Flow Battery Market

Largo

Largo and Stryten Energy have officially formed Storion Energy, a joint venture designed to produce vanadium electrolyte for vanadium redox flow batteries (VRFBs). The collaboration aims to strengthen the U.S. long-duration energy storage (LDES) sector by reducing reliance on imported vanadium-based energy solutions.

Storion will combine Stryten’s proprietary VRFB technology with vanadium pentoxide (V₂O₅) from Largo’s Maracás Menchen Mine in Brazil, providing a reliable domestic supply of vanadium electrolyte for U.S. battery manufacturers. The venture seeks to expand VRFB adoption as an alternative to lithium-ion batteries, particularly in applications requiring extended-duration energy storage.

Reducing Costs to Compete with Lithium-Ion Batteries

One of the major challenges for VRFB deployment in Western markets is the high cost of vanadium electrolyte, which accounts for 40-50% of a VRFB system’s total cost, depending on market vanadium prices.

Storion plans to supply vanadium electrolyte at just $0.02/kWh, well below the U.S. Department of Energy’s (DOE) target of $0.05/kWh for flow batteries that provide at least 10 hours of energy storage. This cost reduction is made possible by:

• Stryten’s advanced technology for efficient electrolyte production.

• Largo’s vanadium leasing model through Largo Physical Vanadium, which helps mitigate upfront material costs.

Strategic U.S. Manufacturing Presence

Storion Energy will operate out of Alpharetta, Georgia—where Stryten’s headquarters is located—and Wilmington, Massachusetts, home to Largo Clean Energy. This dual-location setup will enable efficient production and distribution of vanadium electrolytes, enhancing domestic energy security and accelerating VRFB commercialization.
