The New Energy Storage Industry in 2025: Trends, Challenges, and Opportunities
Industry Growth and Market Trends
The year 2025 marks a significant turning point for the energy storage industry, often referred to as the “year of large-scale energy storage application explosion.” The sector has transitioned from policy-driven growth to market-driven expansion, with applications extending from single-use scenarios to diverse fields including industrial and commercial, grid-side, and overseas markets.
Globally, the energy storage market size is estimated at USD 58.41 billion in 2025, projected to reach USD 114.01 billion by 2030, growing at a compound annual growth rate (CAGR) of 14.31%. This robust growth is fueled by several key factors:
- Renewable Energy Integration: As solar and wind power adoption increases, energy storage solutions are becoming essential to address their intermittent nature.
- Government Policies: Favorable regulations and programs worldwide are accelerating energy storage system adoption.
- Cost Reductions: Lithium-ion battery prices are expected to fall below $100/kWh by 2025, making storage systems more affordable than ever.
In China, the world’s largest energy storage market, new energy storage installations have surpassed pumped-storage hydropower to become the main growth driver. By 2024, China had built 73.76 GW/168 GWh of new energy storage capacity, accounting for over 40% of global installations.
