Superconducting Magnetic Energy Storage (SMES) is an interesting development and has reached market stage in the utility sector. For an application in brake energy storage in railways, the energy density of current SMES is far too low and is not expected to grow sufficiently in the foreseeable future. A transfer to railways is therefore not promising. |
