Double-layer capacitors are becoming a promising solution for brake energy storage in rail vehicles. Competition mainly comes from fly-wheels which at present still offer certain advantages over capacitors. However capacitor technology has developed quite dynamically in the recent past and has been attributed great future potential by some experts. |
