Hungary's battery boom is exacerbating water shortages
Hungary’s strategy to establish itself as a European hub for the production of electric vehicle batteries is increasingly coming into conflict with a growing environmental problem: water scarcity. The Center for European Policy Analysis (CEPA) highlights this in a recent report.
After years of attracting battery manufacturers—particularly Chinese ones—to the country with attractive subsidy programs and streamlined approval procedures, the Hungarian government is now being forced by increasing drought to reassess the balance between industrial growth and sustainable resource management. For the new government under Prime Minister Péter Magyar, this represents one of the first major economic and environmental policy challenges.
Drought puts pressure on Hungary’s water reserves
According to government estimates, Hungary is facing an unprecedented water crisis. For several years, precipitation has been well below average, while at the same time groundwater levels have fallen and water demand from industry and agriculture has risen.
The situation is particularly problematic because battery production is one of the most water-intensive industries. Large quantities of fresh water are required for cooling, refining, and production processes.
During Viktor Orbán’s long tenure, Hungary has developed into a key hub for the European electric mobility industry. According to government figures, Chinese companies have invested around 16 billion U.S. dollars in building production capacity. However, advancing climate change and increasing water scarcity are increasingly calling this model into question.
April 2026 was marked by exceptionally dry weather conditions. According to CEPA, precipitation levels over the past 90 days were between 20 and 70 millimeters below the long-term average. Already last year, approximately 550,000 hectares of farmland were affected by drought damage. More than 90 percent of Hungary’s territory is now considered at high risk of drought.
Farmers warn that securing stable yields is likely to become increasingly difficult in the future without comprehensive countermeasures.
Battery factories are coming under greater scrutiny
At the center of the debate are the numerous battery projects by Chinese manufacturers. Critics argue that rising industrial water consumption is increasingly competing with agricultural irrigation and the population’s drinking water supply.
Particular attention is being paid to the plant of the Chinese battery manufacturer Contemporary Amperex Technology Co. Limited (CATL) in Debrecen. The facility is considered one of the country’s most significant industrial projects and a symbol of Hungary’s transformation into a hub for batteries and electric mobility.
CATL began production of battery cells in early May after receiving all necessary permits. The company emphasizes that it complies with all applicable environmental and water regulations and will also adapt to future regulatory requirements.
However, the new government has already announced plans to significantly tighten environmental regulations. While approval procedures for battery projects were often expedited in the past, future investments are to be subject to comprehensive environmental reviews once again. Existing facilities could also be subject to re-evaluation.
Furthermore, the government is signaling that supplying the population with drinking water and irrigating agriculture will take priority over industrial water consumers in the future.
Stricter requirements for investors
Under current plans, battery manufacturers could be required to make greater use of water recycling systems and graywater. At the same time, environmental inspections are to be intensified, and violations of environmental regulations will be sanctioned more consistently.
There is also discussion of establishing an independent regulatory authority for particularly resource- and environmentally intensive industries. Repeated violations of regulations regarding water or air pollution, as well as the handling of hazardous substances, could result in substantial fines or even plant closures in the future.
Investors appear to be taking the changed regulatory environment into account already. According to media reports, the Chinese automaker BYD has instructed its contractors in Hungary to strictly comply with all labor and environmental regulations.
Balance between growth and sustainability
Despite the planned tightening of regulations, the government does not question the fundamental importance of the battery industry. The sector continues to be seen as a key driver of investment, exports, and employment in Hungary.
Instead of a change of course, Budapest is pursuing a middle ground: the attraction of foreign investors is to continue, while greater consideration is to be given to environmental and resource protection.
At the heart of this strategy is a new water policy. In addition to greater public participation in nature conservation measures, the government is exploring extensive water retention projects. This would partially reverse a decades-long practice in which excess water was drained as quickly as possible via the Danube and Tisza river systems.
For international investors, this represents a fundamental shift. The future of Hungary’s battery sector will no longer depend solely on favorable production conditions and proximity to European markets, but increasingly on the availability of a scarce strategic resource: water.
The central question is therefore no longer just how many battery factories Hungary can attract, but whether the country’s natural resources will even allow for their long-term operation. Water scarcity thus becomes an example of a challenge that many European industrial locations are likely to face in the future: How can economic growth, industrial transformation, and sustainable resource conservation be reconciled?
