The cost of energy storage systems in China often differs significantly from those in other countries due to various factors such as government policies, economies of scale, and technological advancements. Here is a comparison:
Cost Overview
- Lithium-Ion Batteries: In China, the costs for lithium-ion batteries are typically lower compared to other countries. For instance, the average price for turnkey energy storage systems in China can be as low as $90/kWh, reflecting a recent drop from $180/kWh. In contrast, outside of China, lithium-ion battery systems cost around $304/kWh for four-hour discharge durations.
- Other Technologies: For long-duration energy storage (LDES), technologies like thermal energy storage and compressed air storage are cheaper in China compared to many other nations. Globally, thermal energy storage costs about $232/kWh, and compressed air storage costs about $293/kWh. However, in non-China markets, these costs can be significantly higher, with thermal energy storage being 54% more expensive and compressed air storage being 68% more expensive.
Market Drivers
- Government Policies: China’s favorable policies, such as the “new energy + storage” model and government subsidies, have significantly driven down costs and boosted the adoption of energy storage technologies. Provincial mandates requiring a certain level of energy storage alongside new renewable projects further support this trend.
- Scale and Competition: The large-scale deployment of energy storage systems in China benefits from economies of scale and intense competition among manufacturers, which has led to substantial cost reductions. However, other countries are also investing in non-lithium-ion technologies to reduce dependence on imported materials.
- Market Challenges: While China leads in cost and deployment, low utilization rates and lack of effective market pricing mechanisms pose challenges to the sustainability of energy storage development.
Future Outlook
China’s energy storage market is highly competitive and driven by policy support and innovation, leading to lower costs compared to other countries. However, other nations are focusing on developing their own industries, particularly for non-lithium technologies like thermal and compressed air storage, to ensure grid reliability and reduce dependence on imports. The future competition is expected to be shaped by technological advancements, market reforms, and increasing integration with renewable energy systems globally.
