I cam across SMES (Superconducting Magnetic Energy Storage) while researching superconducting and had a few questions I'm hoping to have answered. 1. I have read that SMES devices are primary used in the event for short interruptions in power, and aiding in efficiency in the power grid. Can a SMES device be used like a back up battery in the event of a power outage similar to a back up generator kicking in? Considering some can hold MWH worth of energy I would think that if power went out the SMES device could kick in and provide the back up power needed until it was depleted or the power was restored. 2. Since SMES use superconducting in a way similar to an MRI (superconducting loop) to create a magnetic field to store energy do they loose any of that energy? If so, how much and over what time frame. 3. Do SMES devices need to be ramp-up, again similar to an MRI to reach a field strength or is that irreverent? thanks for the help, Matt R.
