US sodium-ion (Na-ion) battery startup Alsym Energy and domestic manufacturing company Re:Build Manufacturing are partnering to develop commercial-scale battery cell manufacturing capacity in the US.

Announced 2 June, the two companies signed a memorandum of understanding (MOU) to combine Alsym’s Na-ion battery energy storage system (BESS) technology with Re:Build’s manufacturing capabilities.

According to the companies, the collaboration will focus on the development of commercial-scale Na-ion battery cell manufacturing capacity in Re:Build’s existing facility in New Kensington, Pennsylvania.

They further stated, “This domestic-first approach ensures that ESS OEMs and developers can maximise tax benefits under the inflation reduction act (IRA), including the 45X advanced manufacturing production credit, while significantly reducing logistical lead times and shipping costs.”

Mukesh Chatter, CEO of Alsym Energy, said of the MOU, “Our Na-Series batteries fulfill the critical energy needs for AI data centres, utilities, commercial real estate and other industries. It is a better battery for energy storage.”

He continued, “Partnering with Re:Build allows us to accelerate our roadmap toward domestic commercial production. Their expertise in precision manufacturing and battery components is the perfect match for us. Together, we are providing a path for ESS integrators and developers to access high-quality cells that are not only non-flammable and high performance, but are backed by a reliable, non-foreign entity of concern (FEOC) supply chain that is fully compliant with tax credit and defense procurement rules.”

In May, Alsym and California-based renewables developer Juniper Energy announced a 500MWh strategic partnership, which will see Alsym deploy its BESS solution across California.

At the end of April, iron flow battery company ESS Tech Inc announced it had signed a letter of intent (LOI) for a strategic partnership with Alsym. ESS Tech plans to add 8.5GWh of Alsym’s Na-ion cells and modules to its portfolio.

Na-ion deployment and development is continuing to grow in the US. In March, Na-ion BESS startup Peak Energy announced it would pilot a 3.1MWh system at energy firm RWE’s Eastern Wisconsin lab, and that it was evaluating with the company pathways to commercial development.

Last year, Hithium announced its 6.25MWh lithium-ion and N2.28MWh Na-ion BESS solutions for data centres, at the RE+ trade show in Las Vegas.
