Spain is setting new standards in climate protection with an innovative charging station near Barcelona that uses energy from subway brakes to power electric cars. This pilot project showcases a transparent origin of charging electricity for electric vehicles, tapping into a unique energy source. The station draws power from both subway braking and photovoltaic systems installed on nearby metro facilities.

Harnessing Subway Braking Energy
Spain has introduced a groundbreaking pilot project that revolutionizes how electric vehicles (EVs) are charged. In a suburb near Barcelona, a fast-charging station has been developed that utilizes energy generated by the braking of nearby subway trains. This unique approach is combined with energy from photovoltaic panels installed on the metro infrastructure, making the station a model of sustainable energy usage. The two 50-kilowatt charging stations exemplify how renewable energy sources can be harnessed creatively.
MetroCharge: A Self-Sustaining Charging Network
The project, known as MetroCharge, aims to create multiple self-sufficient charging stations that leverage energy from local subway networks. The station near Barcelona is the first of its kind, with plans for six more in the metropolitan area, all situated near subway stops. To use these special charging points, drivers must install the “AMB Electroliners” app on their smartphones. Charging sessions, activated through the app, can last 30 minutes, one hour, or two hours, with costs set at 30 cents per kilowatt-hour. Additionally, a blocking fee of about 40 cents per minute is charged at the end of the session.
Lessons from Global Examples
Carlos Cordón, AMB’s Vice President for Mobility, Transport, and Sustainability, is enthusiastic about the project, highlighting its significance in promoting sustainable urban mobility in Barcelona. The concept isn’t entirely new; similar projects are already underway in Vienna and Germany. Vienna’s public transport system recycles braking energy to power escalators and starting trains, while the German rail network uses regenerative braking technology to supply electricity to other trains on the line. These international examples underscore the potential of regenerative braking to contribute to cleaner, more efficient urban transport.
A Step Towards Cleaner Urban Mobility
The initiative in Barcelona represents a significant step toward integrating renewable energy into everyday life. By drawing power from subway braking systems and solar panels, the charging stations reduce reliance on traditional energy sources. The widespread adoption of such technology could play a crucial role in mitigating urban pollution and reducing carbon footprints. While the exact mix of energy sources for these stations is not fully disclosed, the concept provides a glimpse into a future where public infrastructure actively contributes to sustainable energy solutions.
Spain’s innovative approach to using subway brake energy for EV charging demonstrates the potential for creative solutions in achieving environmental goals. By integrating technology that repurposes existing energy, cities can reduce emissions and enhance sustainability. As this project evolves, it could serve as a blueprint for other urban areas looking to modernize their infrastructure and promote eco-friendly practices.
