The new power system targets high penetration of renewable energy and integrated source-grid-load-storage architecture. As low-cost large-capacity energy storage carriers, sodium-ion batteries serve as essential core equipment supporting the full chain of generation, grid and load sides. On the generation side, paired with wind and solar bases, they store intermittent power to reduce curtailment, smooth fluctuating output, raise grid integration limits and cut reliance on thermal peak-shaving units to advance clean energy transition. On the grid side, large-scale sodium storage stations perform peak shaving, primary & secondary frequency regulation, voltage adjustment and black start backup, easing peak power supply pressure in cities and industrial zones, delaying grid expansion costs and improving power supply resilience against faults. On the load side, distributed sodium storage for households and factories enables self-consumption, peak-valley arbitrage and flexible demand response to flatten overall load curves and reduce transmission pressure. Resource-wise, sodium batteries are free from scarce lithium and cobalt constraints with evenly distributed global raw materials, supporting unlimited storage capacity expansion to meet massive new power system construction demands without supply chain risks. In safety and environmental aspects, superior thermal stability lowers fire propagation risks for densely arranged storage clusters; free of heavy metals with full lifecycle low carbon footprint. Outstanding low-temperature performance fills the storage gap in cold northern regions. Overall, sodium-ion batteries cut total storage costs, accelerate integrated source-grid-load-storage construction and guarantee safe, stable, low-carbon and economical operation of the new power system, forming a core technical route for clean power transition.
