Battery Energy Storage Systems in Korea and Germany

This comparative study examines the current status, challenges, and prospects of large-scale Battery Energy Storage Systems (BESSs) in Korea and Germany. Both nations view BESSs as essential for integrating renewable energy, stabilizing grids, and achieving climate neutrality by 2045 (Germany) and 2050 (Korea). The study highlights the similarities and differences in the deployment of BESSs in the two countries. Korea has established itself as a global leader in battery cell production and has a more advanced deployment status, primarily for frequency regulation and renewable energy integration. However, safety concerns following fire incidents have impacted demand. Germany, on the other hand, has seen a surge in demand for large-scale BESSs due to its energy transition and market environment, with significant growth in arbitrage trading opportunities. 

The study outlines key policy instruments, strategies, and stakeholder involvement in promoting BESS deployment. It also provides a comparative analysis of the two countries, identifying areas for cooperation, such as supply chain resilience, grid integration, and standardization. Recommendations emphasize the need for collaborative efforts to accelerate the deployment of BESSs, enhance renewable energy integration, and achieve cost-effective and sustainable energy transitions. Overall, the study highlights the importance of BESSs in modern energy systems and advocates for strengthened Korean-German cooperation to address shared challenges, foster innovation, and promote the widespread adoption of battery storage technologies.
