With its new project, MetroCHARGE, the city of Barcelona is using regenerative braking technology in its subway trains to power not just the trains themselves, but also station amenities and electric vehicle chargers nearby.
Here’s how it works: every time a train slows down, the energy from braking is captured and converted into electricity. About 33% of this energy goes back into the subway system, reducing its energy consumption by 41% and cutting CO2 emissions by nearly 3,900 metric tons annually. The rest powers station lights, escalators, and even EV chargers at select locations.
This solution isn’t just used in Barcelona. Cities like Vienna, Philadelphia, and New York are also exploring regenerative braking to make public transit more sustainable and following the example of the Spanish city. With a massive subway system, New York could significantly reduce energy costs and emissions if it expanded regenerative braking system-wide.
What an exciting low-hanging solution! Do you know if your city is using it?

@frankoh_kihm_080 100% would love to see implemented in more cities
