• The €27 billion Hungarian battery hub by Chinese battery firms yields minimal domestic spillovers as CATL, BYD, and other Chinese firms use their own integrated supply chains
• European carmaker BMW, which formerly relied on CATL, now diversifies Gen6 battery sourcing to Samsung SDI and LG Energy Solution as other carmakers are pursuing similar diversification
• In addition, Chinese companies like CATL and Semcorp are increasingly struggling to meet environmental protection safeguards

The Centre for Economic and Regional Studies at Eötvös Loránd University (University of Budapest) that Chinese battery investments totaling €27 billion in Hungary have failed to generate promised domestic economic spillovers.

The finding underscores growing operational disruption across Central Europe’s primary electric vehicle manufacturing corridor. The €27 billion pipeline accounts for the majority of Hungary’s foreign industrial capital commitments since 2022.

A cluster of localized supply chains has insulated Chinese cell makers from local suppliers. That structure limits domestic value creation while municipal resistance, environmental sanctions and infrastructure bottlenecks delay factory ramp-ups across the country.

…

Automakers are altering procurement schedules in response. BMW contracted Samsung SDI in Europe and LG Energy Solution in the United States on Nov. 9 for its sixth-generation high-voltage batteries.

The German carmaker previously relied on Chinese suppliers Contemporary Amperex Technology Co. Limited (CATL) and EVE Energy for European cell delivery. The new contracts introduce established South Korean manufacturers to hedge single-region supply vulnerabilities.

CATL is building a €7.34 billion, 100-gigawatt-hour cell manufacturing facility in Debrecen. The project represents Hungary’s largest greenfield foreign direct investment and is designed to supply European assembly lines for BMW, Mercedes-Benz and Volkswagen.

The Debrecen project has encountered regulatory hurdles. The Hajdú-Bihar county government issued a work-stoppage order on the Phase 1 cell plant on Aug. 25 after inspectors recorded nickel emissions exceeding regulatory limits.

Regional regulators restricted activity at the plant to equipment debugging. The county office also rejected CATL’s Phase 2 environmental permit application, which the Chinese battery maker submitted on Aug. 19.

CATL completed remediation work and secured trial permits weeks later. The company began limited trial production on two initial lines on Sept. 22, but commercial series manufacturing remains behind its original timetable.

Component suppliers in the cluster face similar enforcement. Separator producer Yunnan Energy New Material, operating through its subsidiary Semcorp, halted operations at its Debrecen plant for several months following environmental compliance reviews.

Chemical supply lines have also fractured. Hungary’s Ministry of the Interior confirmed on Oct. 18 that the second-instance environmental authority annulled the operating permit for Dongwha Electrolyte in Sóskút.
