In Depth: EU’s Strict Carbon Rules Sap the Energy of Chinese Battery Giants

Chinese battery manufacturer Contemporary Amperex Technology Co. Ltd. (CATL) is transitioning its production to use green electricity due to increasing pressure from the European Union’s stringent battery regulations. The EU regulations, effective as of August 2023, impose stricter carbon footprint standards on batteries imported by the bloc, making it challenging for Chinese manufacturers reliant on their coal-heavy energy mix to comply. This shift is prompted by the expectation that by 2028, Chinese batteries may not comply with EU sales standards.[para. 1][para. 2][para. 3]

The EU's new battery regulations mandate that all batteries sold within its borders must provide a carbon footprint report by 2025 and display carbon performance labels by 2026, with batteries exceeding carbon limits banned from 2028. These regulations are significant for China, which is a major supplier of batteries to the EU, especially with top importers like Germany and Spain.[para. 3][para. 4][para. 5]

The regulations cover the entire lifecycle of a battery, highlighting the substantial contribution of electricity, which accounts for over 60% of a battery’s carbon footprint. The current energy mix in China, still heavily reliant on coal, presents a significant challenge, pushing CATL and others toward green electricity solutions. This national average dependency results in a carbon emission factor substantially higher than that of EU nations.[para. 6][para. 7][para. 8]

The regional push for direct electricity supply options poses multiple challenges. While direct power supply could reduce the carbon footprint by bypassing the traditional power grid and its associated carbon factors, fluctuating supply levels with renewable energy sources remain a hurdle. Furthermore, the EU’s rules recognize only national averages, sidelining previously considered local or provincial-specific calculations, which predominantly impacts Chinese manufacturers.[para. 9][para. 10][para. 11][para. 12]

CATL has been spearheading initiatives, such as deploying solar photovoltaic systems across its factories, though these provide just 3% of the total energy needed, necessitating reliance on the main grid. Despite efforts to source cleaner energy sources and the inherent challenges in adjusting production to direct electricity supply, the large-scale consumption still relies heavily on the main grid, reflecting the broader national power mix.[para. 13][para. 14][para. 15][para. 16]

Additionally, the concept of direct electricity supply involves not only technical but also policy-related challenges. CATL's plans to invest in dedicated power supply lines, tapping directly into nuclear and hydroelectric sources, face hurdles within China’s current policy frameworks. The regional adaptation of this model invites resistance from grid companies concerned about potential revenue losses and infrastructural impacts.[para. 17][para. 18][para. 19][para. 20]

With China’s renewable energy strategy under development, including a shift toward establishing direct supply models, several regions are experimenting with green electricity systems. However, achieving a significant infrastructural shift is impeded by both financial and political factors, despite CATL’s willingness to negotiate associated costs to gain access to EU markets.[para. 21][para. 22][para. 23][para. 24]

Overall, while CATL continues to explore solutions to adhere to EU standards, its reliance on domestic grid power highlights the ongoing policy dilemma in transitioning towards green electricity on a national level. The company remains committed to advancing these changes despite the systemic and financial challenges involved.[para. 25][para. 26][para. 27][para. 28][para. 29][para. 30]
