U.S. Energy Storage Market Analysis

Based on technology the market is segmented into pumped hydro, electro-chemical, electro-mechanical, and thermal energy storage. The U.S. market for energy storage reached USD 64.9 billion, USD 81.9 billion and USD 106.7 billion in 2022, 2023 and 2024 respectively.
 

• The pumped hydro technology battery uses excess electricity to pump water from lower to upper reservoir. The technology offers longer duration storage. Owing to this pumped hydro is majorly used in renewable energy integration and grid energy storage systems. Due to these factors government of different countries are initiating positive strategies.
   
• For instance, in November 2024 Sperra a U.S. based energy provider received USD 4 million fund from the US Department of Energy Water Power technologies Office to foster innovation in pumped storage hydropower technologies.
   
• Rising sales of EV in the nation is rising demand for electro-chemical energy storage majorly lithium-ion. For instance, sales of EVs in U.S. by General Motors (GM) in Q3 2024 registered over 9,700 units sales in the nation specifically accounting more than 30% revenue share from the country.
   
• Owing to high demand for lithium-ion batteries from different users such as automakers, consumer electronics, various companies and researchers have initiated to invest prominently to develop new technologies such as sodium sulfur technology and are currently in early stages.
   
• Solar power is gradually capturing significant growth in the energy industry. For instance, in 2024, the U.S. added nearly 48.2 gigawatts renewable energy capacity. The growing adoption of solar energy worldwide is expected to boost the demand for thermal energy storage systems.  
   

The U.S. energy storage market by application is segmented into electric time energy shift, electric supply capacity, black start, renewable capacity firming, frequency regulation and others. The electric time energy shift segment accounted for 38.2% of the market share in 2024.
 

• The growing hurricane and other natural disasters leading to rising energy outage and cost of electricity units. For instance, Entergy the electric company in Louisiana increased energy unit rate by $8 a month after the destructive hurricanes in 2020 and 2021.
   
• In addition, this rate for the U.S. residential electricity bills was again increased by 2% in in 2023. Such instances is likely to increase demand for energy time shift to off period and peak shaving of energy. This reduces the cost and increases the availability of energy which will increase demand for ESS majorly from electric energy time shift, electric supply capacity applications.
   
• Owing to rise in adoption of EV due to rising adoption of environmental friendly transportation and favorable government policies in the field, the energy storage market is expected to witness higher demand. 
   
• Favorable government initiatives to promote ESS in U.S. is likely to increase demand for ESS in future. For instance, Inflation Reduction Act (IRA) provides 30% credit on all residential ESS over 3 kWh in capacity until 2032. For standard household energy storage system IRA reduces cost of ESS by USD 3,000 to USD 5,000.
   
• Furthermore, increasing deployment of solar power and cost-effective ESS technologies in the U.S. is likely to boost the demand for energy storage systems in U.S.
