EV-Friendly Brakes

Barcelona’s MetroCharge project is transforming urban sustainability by using regenerative braking energy from metro trains to charge electric vehicles (EVs). At 16 subway stations, energy captured during braking is redirected to power trains, station operations, and nearby EV charging points, reducing reliance on conventional energy sources and promoting greener transportation.

This innovative system, supported by European Union funding, integrates urban planning with renewable energy efficiency. 'The energy goes directly to nearby charging stations, boosting efficiency and potentially lowering costs for EV users,' explains Professor Alvaro Luna of the Polytechnical University of Catalonia.

Incorporating solar panels, the system provides energy for 28 subway stations, saving 6% of the metro’s total energy consumption. While addressing challenges like Spain’s limited charging infrastructure, the MetroCharge project exemplifies how cities can use clean energy to tackle climate change and foster sustainable mobility, setting a benchmark for urban green initiatives.
