Support the Clean Energy Transition of Sodium Nitrate

Large‑Scale Concentrated Solar Power (CSP) and Thermal Storage
High‑purity molten‑salt grade sodium nitrate is the core heat‑transfer and storage medium in CSP plants. It is commonly mixed with potassium nitrate (e.g., the binary salt of 60% Sodium Nitrate + 40% Potassium Nitrate). Approximately 99.8% of all commissioned CSP plants worldwide use this molten‑salt technology.

Sodium nitrate shows unique value in improving battery performance:

Sodium‑Ion Batteries helps form a stable solid‑electrolyte interphase (SEI) layer, significantly enhancing low‑temperature performance and fast‑charging capability, while also slowing internal resistance growth during high‑temperature storage.

Researchers have developed a quasi‑solid electrolyte based on sodium nitrate, which is low‑cost and high‑performing, offering a new pathway for next‑generation flexible energy‑storage devices.

Sodium nitrate is also used as a dopant to develop solid‑state electrolytes from biopolymers like cotton, aiming for safer and more sustainable sodium‑ion batteries.
