Sodium-air Battery Market size was over USD 2.12 billion in 2024 and is projected to cross USD 5.05 billion by the end of 2037, growing at more than 6.9% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of sodium-air battery is estimated at USD 2.24 billion.
This growth in the market revenue is poised to be dominated by growing demand for electric vehicles. For instance, approximately 9 million electric cars were purchased in 2022 and this year it is set to expand at about 34% which equates to close to 13 billion electric vehicles. Hence, the demand for sodium-air batteries is estimated to rise. Moreover, the government is offering subsidies for the purchase of electric vehicles which has driven more attention from common people.
Additionally, the use of porous carbon in the cathode of sodium-air batteries is also set to grow owing to it being lightweight. However, besides this porous carbon has an exceptionally specific surface area and pore structure and is also composition-designable. Furthermore, porous carbon has outstanding mechanical and electrical qualities owing to the high electrical conductivity of carbon materials and their distinctive microstructure. Therefore, with the growth in manufacturing of lightweight porous carbon the market demand might grow but there is still more research to be done in this field. Hence, the rise in R&D activities in the utilization of lightweight porous carbon in the cathode of sodium-air battery is expected to expand market growth in the coming years.

Electrolyte (Aqueous, Non-Aqueous)
The non-aqueous segment is projected to account for 60% share of the global sodium-air battery market during the forecast period. This could be on account of the wider liquid range offered by non-aqueous electrolytes. Moreover, it also consists of a greater voltage window which makes it fit for a sodium-air battery as compared to an aqueous electrolyte. Hence, with this adoption, the sodium-air battery could be able to store large amounts of energy. As a result, the demand for this segment is surging.
End-Use (Utility Energy Storage, Automotive, Defense, Consumer Electronics, Power)
The utility energy storage segment is estimated to garner the largest share in the sodium-air battery market at about 35% by 2037. The major factor driving the segment growth is rising investment in grid infrastructure for renewable energy. For instance, the has been growth in overall investment which consists of about USD 3 trillion for system maintenance and approximately USD 16 trillion for infrastructure expansion to accommodate increased power generation and demand. Moreover, the amount invested annually also triples from close to USD 273 billion in 2022 to over USD 871 billion in the ten years before 2050. Moreover, there are many rural regions where the supply of electricity is difficult. Therefore, there are certain sustainable energy projects taking place. However, dependence on lithium-ion batteries could hinder these projects since lithium needs to be exported from other parts of countries as it is not available in abundance. As a consequence, the demand for sodium-ion batteries is surging in order to provide utility energy storage in rural parts.

North American Market Forecast
The North America region sodium-air battery market is poised to gather the highest share of approximately 35% during the forecast period. The growth of the market in this region is set to be influenced by growing government investment in wind energy. In 2021, the U.S. wind sector built 13,413 megawatts (MW) of additional wind capacity, bringing the total installed wind capacity to 135,886 MW. With an investment of USD 20 billion, this is the second-greatest amount of wind capacity set up in a single year (after 2020). Moreover, if present and future capacity expansion plans continue as planned, wind power could produce approximately 39 percent of North America's electricity by 2050 and solar power another about 31%.
European Market Analysis
The sodium-air battery market in Europe is also projected to experience the significant growth during the coming years. The market in this region is growing on account of rising government strict regulations to lower the carbon emission and achieve zero emission target in coming years. Additionally, this region consists of large number of key players involved in field of manufacturing sodium-air battery. As a result, the market in this region is facing upward movement.
