US Government Says Relying on Chinese Lithium Batteries Is Too Risky

Analysts on the US Division of Homeland Safety shared an inside report back to native companies in August, warning them in regards to the financial dangers of utilizing Chinese language utility storage batteries. It warns that the dependence on Chinese language batteries might damage creating a safe provide chain within the US.

The doc, first obtained by nationwide safety transparency nonprofit Property of the Individuals and seen by WIRED, accuses Chinese language firms of “utilizing Individuals’s Republic of China state assist to rapidly and cheaply enter the rising US utility battery power storage trade and create provide chain dependencies on China,” and asks that any suspicious exercise be reported.

Particularly, the report alleges three firms—Modern Amperex Know-how Co. Restricted (CATL), Construct Your Goals (BYD), and Ruipu Vitality Co. Ltd. (REPT)—have “benefited from the assorted types of state assist and leveraged this to additional enterprise methods for gaining US market share.”

At present, CATL and BYD lead the worldwide power storage battery market by far, with 40 percent and 12 percent market shares, respectively, in accordance with South Korean power analysis agency SNE Analysis. Eight out of the ten prime firms within the trade are from China, so there are few alternate options to show to when constructing grid storage.

The report says it builds on earlier paperwork that analyzed Chinese language “state-supported companies’ use of noncompetitive ways within the electrical automobile and battery provide chains.” DHS didn’t reply to a request for additional remark.

In 2022, CATL entered a take care of Primergy Photo voltaic to construct the most important US photo voltaic and storage undertaking in Nevada, which got here on-line this 12 months. Its battery merchandise have additionally been utilized by Duke Vitality, a North Carolina–primarily based utility firm, though the latter dropped CATL as a supplier for marine base electricity storage after considerations round nationwide safety have been raised by, partially, lawmakers in Washington.

In an emailed assertion, Fred Zhang, a CATL spokesperson, rejects the categorization that the agency has relied on state assist to realize an edge. “CATL has achieved super development by steady innovation, farsighted strategic planning, and a dedication to high-quality merchandise at an inexpensive value,” the assertion says.

BYD and REPT didn’t reply to WIRED’s request for remark.

Following efforts to curb Chinese language EV firms’ competitiveness, the US authorities is now additionally involved about how home utility firms might develop into too depending on Chinese language batteries for power storage.
