In-depth Analysis Report on Chinese Energy Storage Enterprises Going Global: Status, Drivers, and Challenges in 2024

1. Current Status Overview

In 2024, Chinese energy storage enterprises continue to accelerate their global expansion. According to data from China Customs and industry research institutions, exports of lithium-ion battery energy storage systems from China exceeded USD 6 billion in the first half of 2024, a year-on-year increase of approximately 35%. Major export destinations include the United States, Europe (especially Germany and the UK), Australia, and Southeast Asia. Leading companies such as CATL, BYD, Sungrow Power Supply, and Huawei Digital Power hold the majority of market share, while second-tier manufacturers like REPT Batteries and Eve Energy are also accelerating their overseas layouts.

2. Driving Factors

• Cost Advantage: Chinese companies have scale production advantages in lithium iron phosphate (LFP) battery technology, with cell costs 20% to 30% lower than overseas competitors.
• Policy Support: China's "dual carbon" goals drive the upgrading of the energy storage industry, while overseas countries such as the US (Inflation Reduction Act) and the EU (REPowerEU plan) provide subsidies and tax incentives for energy storage, stimulating demand.
• Complete Supply Chain: China possesses a complete supply chain from lithium processing to battery manufacturing, coupled with efficient port logistics and short delivery cycles.

3. Major Challenges

• Trade Barriers: The US imposes a 301 tariff on Chinese energy storage batteries (with some categories reaching 25% in 2024), and the EU plans to introduce a Carbon Border Adjustment Mechanism (CBAM), increasing export costs.
• Standards and Certification: Overseas markets have strict safety certification requirements for energy storage products (e.g., UL9540, IEC62619), requiring significant time and financial investment from companies to obtain certification.
• Localization Operations: Insufficient local after-sales and maintenance teams, along with cultural differences and unfamiliarity with local regulations, have led to delivery delays in some projects.

4. Development Recommendations

• Deepen Localization: Prioritize establishing joint ventures or cooperative R&D centers in target markets. For example, CATL sets up factories in Hungary and BYD in Brazil.
• Enhance Technological Barriers: Increase investment in next-generation technologies such as solid-state batteries and sodium-ion batteries to break through overseas patent barriers through differentiated competition.
• Build Ecosystem Cooperation: Collaborate with overseas energy companies, grid operators, and financial institutions to provide integrated "energy storage + solar + operation and maintenance" solutions.

5. Future Outlook

It is estimated that by 2028, the overseas market share of Chinese energy storage companies will increase from the current 35% to over 45%, but they must remain vigilant against the dual impacts of geopolitical risks and raw material price volatility.
