Energy transition accelerates, energy storage battery concept stocks become a new investment track

The global carbon neutrality goals are becoming increasingly clear, and the new energy industry is entering a period of rapid development. Large-scale deployment of renewable energy sources such as wind and solar power, the continuous rise in electric vehicle penetration, and unprecedented demand for energy storage all point in the same direction—Energy Storage Battery Concept Stocks are becoming the focus of capital markets.

Overview of the Energy Storage Industry Chain: A Complete Ecosystem from Raw Materials to Applications

To understand the investment opportunities in energy storage battery concept stocks, first recognize the structure of the entire industry chain.

Upstream Raw Materials and Components form the industry foundation. This includes key minerals such as lithium, cobalt, nickel, core chemicals like cathode materials, electrolytes, separators, as well as precision components like battery management systems, cooling equipment, and power conversion modules. Companies like Formosa Plastics (6505) have deep layouts in electrolytes and possess strong technological barriers.

Midstream Battery and System Manufacturing is the core of value. Different energy storage scenarios demand various types of batteries—lithium batteries dominate due to their energy density advantages, solid-state batteries are highly anticipated for high-end applications, and sodium-ion batteries, being low-cost, are suitable for large-scale deployment. Taiwanese companies such as New Power (4931), Changyuan Technology (8038), continue to deepen technological accumulation in battery manufacturing.

System Integrators play a bridging role. They not only integrate components like batteries, inverters, battery management systems, and energy management systems but also handle the design, deployment, and operation of entire energy storage solutions. Taiwanese system integrators like Huacheng (1519), Yali (1514), and ZTE Electric (1513) already possess international competitiveness.

Downstream Applications include grid-side energy storage, user-side energy storage, electric vehicles, and more. As energy demands from AI data centers surge, backup power supplies and energy storage systems are becoming new growth engines.

Explosive Growth of the Global Energy Storage Market

According to the latest research forecasts by BloombergNEF and DNV, by 2030, the global cumulative installed capacity of energy storage excluding pumped hydro will surpass (TWh). Lithium-ion batteries will continue to dominate the energy storage market, but emerging technologies like sodium-ion batteries are rapidly gaining attention.

This growth is driven by three factors: first, strict carbon emission control policies in various countries. The Intergovernmental Panel on Climate Change (IPCC) explicitly states that to keep global warming within 1.5°C above pre-industrial levels, global carbon emissions must be halved by 2030 and reach net-zero by 2050. This provides a policy foundation for the entire clean energy industry.

Second, the rapid decline in renewable energy costs. With technological advances, wind and solar power generation costs are now competitive, but their output volatility (e.g., wind power producing negative prices at dawn) makes energy storage an essential supporting infrastructure. Third, the explosive growth of new electricity demand, especially from AI data centers requiring highly stable power supplies.
