US Government Says Relying on Chinese Lithium Batteries Is Too Risky
Analysts at the US Department of Homeland Security shared an internal report to local agencies in August, warning them about the economic risks of using Chinese utility storage batteries. It warns that the dependence on Chinese batteries could hurt developing a secure supply chain in the US.
The document, first obtained by national security transparency nonprofit Property of the People and seen by WIRED, accuses Chinese companies of “using People’s Republic of China state support to quickly and cheaply enter the emerging US utility battery energy storage industry and create supply chain dependencies on China,” and asks that any suspicious activity be reported.
Specifically, the report alleges three companies—Contemporary Amperex Technology Co. Limited (CATL), Build Your Dreams (BYD), and Ruipu Energy Co. Ltd. (REPT)—have “benefited from the various forms of state support and leveraged this to further business strategies for gaining US market share.”
Currently, CATL and BYD lead the global energy storage battery market by far, with 40 percent and 12 percent market shares, respectively, according to South Korean energy research firm SNE Research. Eight out of the 10 top companies in the industry are from China, so there are few alternatives to turn to when building grid storage.
