Battery project developer Alsym Energy and US‑based renewables developer Juniper Energy have announced a strategic partnership to deploy 500 MWh of Battery Energy Storage Systems (BESS), mainly within the state of California (United States) (Alsym Energy press release, 12/05/2026).
Under the agreement, Juniper Energy will integrate Alsym’s Na‑Series technology, with plans to deploy sodium‑ion battery storage in the Mojave Desert. Alsym Energy officially launched its Na‑Series in October 2025, highlighting it as non‑flammable and non‑toxic. “As California continues to lead the nation’s energy transition, the need for safe, long‑duration storage that can withstand extreme ambient thermal conditions is paramount. By integrating Alsym’s Na‑Series technology, Juniper Energy will deploy storage assets that eliminate the fire risks associated with traditional chemistries while significantly reducing the levelized cost of storage (LCOS)”, states the company’s press release.
The first phase of the partnership centers on multi‑megawatt deployments in California, with the ambition to scale Alsym‑powered assets across Juniper Energy’s entire development pipeline in the longer term.
