(AI-generated image)* Hungarian lawmaker Zsolt Tárkányi published confidential government records on Nov. 4, 2026, disclosing infrastructure pacts signed with Contemporary Amperex Technology Co., Limited for its 100-gigawatt-hour Debrecen factory. Tárkányi, a State Secretary in Hungary's Ministry of Transport and Investment, released the second tranche of a non-binding August 2022 memorandum between CATL and the former Viktor Orbán administration. The leaked accord covers an industrial facility representing €7.34 billion ($8 billion) in capital expenditure, where CATL started trial cell operations on Sept. 22 for a 40-gigawatt-hour initial phase. Under the 2022 memorandum, the Debrecen municipal council agreed to expropriate and service the factory site, waiving all municipal development expenses beyond the basic land acquisition cost. Hungarian authorities committed to deliver the serviced plot in the Southern Industrial Park of Debrecen, shielding the Chinese battery manufacturer from utility connection and ground preparation overhead. The national government pledged additional assistance to help CATL secure more than 100 hectares of contiguous expansion land within a 50-kilometer radius of the main factory complex. The agreement outlined extensive workforce concessions to staff the battery plant, including accelerated entry visas for non-European Union personnel from China and third countries. Hungarian ministries scheduled 6,000 non-EU worker entries by late 2024 under the arrangement, while establishing a permanent residency allocation of 1,000 to 2,000 foreign technical specialists after commercial launch. The former cabinet also committed to construct and assign thousands of public rental housing apartments in Debrecen to accommodate the influx of foreign and domestic manufacturing employees. State funds were earmarked to cover 50% of worker vocational training costs, capped at €2 million ($2.18 million) per program or €5,000 ($5,450) per individual employee. The disclosure follows an earlier document leak by Tárkányi on Oct. 6, which detailed an 80% corporate income tax exemption for CATL spanning 13 consecutive operational years. The October filing revealed up to €15 million ($16.3 million) in direct tax credits for capital expenditure directed toward corporate energy efficiency improvements at the Debrecen site. The released document does not state the exact volumes of electricity and water promised to CATL, as Tárkányi redacted those utility figures before publication. Redacted sections conceal peak electrical grid capacity and daily cubic meter allocations, preventing independent verification of the public infrastructure committed to battery production lines. CATL built the 221-hectare Debrecen complex to serve as its primary European production base, targeting a full capacity of 100 gigawatt-hours to support regional electric vehicle supply chains. The Chinese battery manufacturer previously started battery module assembly at the Debrecen site in autumn 2024, delivering 537,000 assembled modules to automotive clients before cell testing began. Mercedes-Benz Group committed in 2022 as the lead anchor customer for the Debrecen facility, reserving cell supply for next-generation electric vehicle assembly across German and Hungarian plants. BMW AG constructed a dedicated assembly complex for electric passenger vehicles in Debrecen, relying on adjacent battery cell deliveries to feed localized battery pack integration. The Debrecen factory represents CATL's second European cell manufacturing hub after its facility in Erfurt, Germany, which reached commercial deliveries in 2023. Operating friction and occupational hazards have already slowed the ramp-up schedule at Debrecen. Workplace safety inspectors ordered a temporary halt across three manufacturing sections in August. The county government agency issued the stop-work order after tests confirmed excessive occupational nickel exposure among nine factory employees during cleanroom equipment commissioning. The Hajdú-Bihar County Government Office rescinded the stop-work order in early September after CATL modified protective ventilation filters, allowing trial operations to start on Sept. 22. Regional environmental disputes continue to center on industrial water consumption. Municipal contractors have failed to finish the permanent industrial wastewater and greywater pipeline connecting the industrial park. To maintain trial production across its first two automated cell assembly lines, CATL began drawing cooling water directly from local groundwater aquifers, triggering intense protests from Debrecen residents. Civic coalitions and local agricultural organizations warned that prolonged groundwater extraction will deplete regional aquifers already stressed by eastern European summer droughts. Legal challenges against the battery facility reached the judicial system earlier this year. The Debrecen Regional Court issued a final ruling on Oct. 30 dismissing a resident lawsuit. The lawsuit had sought the immediate revocation of CATL's integrated pollution prevention and control permit, but judges ruled that operational safety filings satisfied national standards. While the court decision eliminated the immediate risk of a judicial injunction, political opposition to the gigafactory project has intensified under Hungary's shifted political landscape. The newly formed government of Prime Minister Péter Magyar, whose Tisza party defeated Orbán's coalition, declared that it will not grant regulatory approval for Phase 2 and Phase 3. Magyar announced that the administration will block all additional state subsidies and deny permits required to expand site capacity from 40 gigawatt-hours to the planned 100 gigawatt-hours. Tárkányi stated that the leaked 2022 memorandum proved the previous administration transferred excessive municipal resources and legal privileges to overseas manufacturing capital without parliamentary consent. European carmakers facing softening electric vehicle sales volumes cannot easily relocate cell procurement contracts without incurring heavy tooling penalties and multi-year supply interruptions. The Debrecen facility operates under an occupancy permit granted in August, but commercial series manufacturing remains contingent on completing final utility validation before year-end. Debrecen water authorities face a Dec. 31 deadline to connect the municipal industrial pipeline, which will determine whether CATL can halt groundwater pumping before full series production begins. ## Impact map | Event | Korea | China | Japan | Global impact | | --- | --- | --- | --- | --- | | Leaked Debrecen battery accord | LG Energy Solution and Samsung SDI face intact competitor capacity in Central Europe | CATL retains Phase 1 trial lines but loses state backing for Phase 2 and Phase 3 expansion | Japanese separator suppliers face delayed volume ramps tied to downstream European EV programs | European automakers absorb supply chain vulnerability on 40 GWh Hungarian cell allocation | ## In this story - **Companies:** Contemporary Amperex Technology - **Tickers:** 300750.SZ - **Exposed:** Mercedes-Benz Group, BMW AG - **Policy:** Subsidies, Tax Credits - **Impact:** Supply Chain, Capex, Compliance ## Primary sources 1. telex.hu 2. hvg.hu 3. dehir.hu 4. forbes.hu 5. blikk.hu --- Cite as: East Asia Brief, "Hungary official leaks CATL accord offering land and tax breaks," November 5, 2026. https://eastasiabrief.com/batteries-ev/hungary-official-leaks-catl-accord-offering-land-tax-breaks-1142
