Energy storage batteries have become a hot topic in the period of energy transformation.


With the new requirements for carbon neutrality and energy transition, domestic energy storage projects in China have become increasingly popular both in terms of corporate deployments and institutional investments. According to China Energy Storage Network, during the period from January to June 2023, the newly commissioned capacity of new energy storage projects reached approximately 8.63 GW/17.72 GWh, equivalent to the cumulative installed capacity of previous years. In terms of investment scale, the direct investment driven by the newly commissioned energy storage projects exceeded RMB 30 billion.

Looking globally, the worldwide energy transition and the energy shortage resulting from the Russo-Ukrainian War have made energy storage batteries a hot topic in the new economic landscape. In 2022, the global energy storage battery shipments totaled 142.7 GWh, a substantial increase of 204.3% compared to the 46.9 GWh in 2021. The upstream of energy storage batteries includes raw materials and battery production equipment, the midstream covers energy storage battery manufacturing and system integration, while the downstream applications span multiple industries. Upon further examination, it is evident that most of the manufacturers of energy storage batteries in the international market are dominant players concentrated in the midstream sector, with only a few companies having a significant presence in the upstream and downstream segments of the energy storage industry. In this survey, EqualOcean will focus on the leading companies in the manufacturing and integration of energy storage batteries in international markets.

In the realm of top-tier enterprises, it is evident that only a handful are exclusively focused on energy storage batteries. The majority possess ancillary operations beyond energy storage or strategically expand along the upstream and downstream segments of the energy storage value chain. This strategic maneuvering is aimed at capitalizing on economies of scale and asserting dominance. This phenomenon eloquently underscores the maturity achieved by the energy storage sector, having successfully navigated its tumultuous infancy.

Simultaneously, EqualOcean's investigation reveals that energy storage battery companies with international operations exhibit a discernible absence of geographical bias in their global market deployment. These companies often establish their presence across multiple continents, further corroborating the globalized nature of energy storage battery applications.
