en.Wedoany.com Reported - Energy storage provider ESS Tech Inc. is accelerating the development and production of non-lithium battery systems, following a surge in early customer interest.

The company stated that since signing a letter of intent with battery manufacturer Alsym Energy at the end of April, it has seen strong early customer engagement across the United States. This surge in interest, particularly around its planned U.S.-manufactured sodium-ion battery energy storage system, has prompted executives to reallocate company resources to support accelerated production.
ESS Tech CEO Drew Buckley said the demand for sodium-ion seen by the company is historically unprecedented. He noted that energy demand is changing faster than the market can respond, and past solutions cannot fill the gap. The company is acting decisively to meet demand, accelerating toward near-term revenue while building the foundation to deliver at the required scale and speed.
Buckley and the Wilsonville, Oregon-based company stated that sodium-ion batteries will see hyperscale use in data centers, utility markets, and other critical infrastructure applications. ESS Tech has developed nearly $1 billion in early opportunities for these batteries and is accelerating BESS platform development to meet growing immediate demand.
Customers, including power hyperscalers and data center developers, urgently need energy storage solutions that are safe, easy to deploy, and free from supply chain risks. The company stated that modern energy storage systems must avoid fire and lithium-ion insurance risks while meeting tight energy delivery timelines. Customers need to eliminate concerns about foreign entities, and sodium-ion batteries, with all materials available for domestic sourcing, are uniquely suited to fill this gap.
Buckley added that this transformation allows ESS to pursue attractive market opportunities while maintaining its long-term innovation commitments. He stated that the company believes it can create value for customers and shareholders by focusing the organization on high-growth markets using differentiated technologies, leveraging proven execution capabilities, and consistently delivering U.S.-manufactured energy storage solutions.
In addition to sodium-ion BESS products, ESS Tech will continue developing iron flow battery technology for long-duration applications. The company plans to announce sodium-ion battery containers, racks, and other hardware solutions, as well as digital software products.
