How do moving magnet pumps work?
Moving magnet pumps (MMP’s) work by having liquid metal flows in the direction of magnet rotation. (Disc-style MMP’s typically have two discs, one on either side of the duct. For this image, the second disc was omitted for clarity.) MMP’s are powerful and useful tools with immediate industrial applications.
What is a moving magnet pump (MMP)?
A moving magnet pump (MMP) is a unique type of electromagnetic (EM) pump that does not suffer from the shortcomings of other induction-style EM pumps. MMPs produce a traveling magnetic field that induces electrical currents within electrically-conductive liquid metals.
What is superconducting magnetic energy storage (SMES)?
2.7. Magnetic energy storage Superconducting magnetic energy storage (SMES) can be accomplished using a large superconducting coil which has almost no electrical resistance near absolute zero temperature and is capable of storing electric energy in the magnetic field generated by dc current flowing through it.
When were the first EM pumps created?
To take advantage of promising liquid-metal technologies, many different types of electromagnetic (EM) pumps have been created since the 1940’s. High-temperature, liquid metals can be used in a variety of ways to enhance both energy production and energy storage, as highlighted by Table 1.
What is pumped hydro and compressed air energy storage?
