Sodium Ion Energy Storage System Price: The $45/kWh
With global energy storage demand projected to reach 1.2 TWh by 2030 according to the 2024 Global Energy Storage Monitor, sodium-ion batteries are emerging as the dark horse of renewable
Then again, Barker says, BYD and CATL say that sodium-ion batteries will eventually cost $10 or $20 per kilowatt-hour. Barker says he doubts such costs are achievable in the near term, but he also knows that making predictions about the zigzag path of the battery business is a no-win game.
Assuming a similar capex cost to Li-ion-based battery energy storage systems (BESS) at $300/kWh, sodium-ion batteries' 57% improvement rate will see them increasingly more affordable than Li-ion cells, reaching around $10/kWh by 2028.
With costs fast declining, sodium-ion batteries look set to dominate the future of long-duration energy storage, finds AI-based analysis that predicts technological breakthroughs based on global patent data. Sodium-ion batteries' rapid development could see long-duration energy storage (LDES) enter mainstream use as early as 2027.
The sodium-ion cells, which have an energy density of 175 Wh/kg, feature a cathode made of a sodium iron hexacyanoferrate material known as Prussian white. CATL's goal is to produce a sodium-ion battery with an energy density that exceeds 200 Wh/kg. CATL claims it has already overcome one negative aspect of sodium-ion batteries: slow charging.

Overall, LIBs maintain a slight cost advantage at present, considering costs per kilowatt-hour of energy capacity (kWh cap), as SIBs generally exhibit lower gravimetric energy density.
A report from the International Renewable Energy Agency (IRENA) notes that while it is still uncertain whether sodium-ion batteries will become a disruptive alternative to lithium-ion
A challenge for sodium-based batteries is that they now cost more per kilowatt-hour than lithium-iron-phosphate batteries.
CATL''s sodium-ion batteries promise $10/kWh storage and 90% lower costs. See how they could transform EVs and grid energy worldwide fast.
Discover 2025 energy storage system cost trends: residential, commercial, and utility-scale averaging $130–$400 per kWh. Explore LFP and sodium-ion battery benefits, policy incentives,
The Global Sodium-ion Battery Market is projected to grow from $483.5 million in 2024 to $1.3 billion by 2030, registering a CAGR of 17.2% during the forecast period. The market growth is driven by the
CATL''s announced sodium-ion battery pricing of $19 per kilowatt hour represents a 65% reduction from current lithium iron phosphate costs of $55-$70/kWh, not the 90% cost decline
The average cost for sodium-ion cells in 2024 is $87 per kilowatt-hour (kWh), slightly cheaper than Lithium-ion cells at $89/kWh. Assuming similar capital expenditures, sodium-ion
