| Abstract |
This study provides a multifaceted analysis of the deployment and applicability of eco-friendly technologies in the electric railway sector to support the achievement of RE100 implementation and carbon neutrality goals. Specifically, it examines renewable energy-based electricity supply, energy storage systems (ESS), regenerative braking energy recovery, smart energy management systems, and green infrastructure designs, based on a comparative evaluation of domestic and international cases. The paper evaluates the potential for structural energy transformation within electric railway systems and explores how RE100 objectives can be technically aligned and policy-integrated into railway operations. Furthermore, it presents a strategic roadmap to guide the Korean railway industry’s transition toward a sustainable transportation system compliant with global RE100 standards. This integrated approach is expected to offer practical insights for policymakers and railway operators in addressing electricity demand management, greenhouse gas reduction, and future energy grid stability. The study ultimately contributes to the development of a comprehensive green transition strategy grounded in the electric railway infrastructure. |
