Dr. James Powell and Dr. Gordon Danby received a patent in 1968 for Superconducting Maglev. Their ideas were made operational in Japan earning the world record for maglev transport speed. Powell and Danby joined Albert Einstein, Nikolai Tesla, Charles Steinmetz, Marie and Pierre Curie, Orville Wright, Werner von Braun and Alexander Graham Bell when they were awarded the prestigious Benjamin Franklin Medal of Engineering in 2000. Their research and discoveries continue.

MAPS 2nd GenerationMaglev-2000 System

The patented MAPS 2nd generation Maglev-2000 system has the capability to climb steep grades of 20 to 30%, very high propulsion efficiency, over 90%, very low cost guideway, very high levitation force, and the ability to electronically switch from one guideway to another without using mechanical switches. For an elevation change of 1 kilometer, each 100 tonne block will store 270 KWH. Each maglev sled can make 15 to 20 round trips per hour, depending on site location, storing or delivering up to 40 megawatt hours over an 8 hour period. The sleds have flat upper surfaces with roller bars that can quickly load and unload the concrete blocks. Nominal block dimensions are 3 m wide, 4.2 meters long and 3.2 meters high. At 50% filling factor, to store 1000 megawatt hours using 4000 blocks, the upper and lower storage yards would be much smaller in area than pumped hydro lakes, with each yard occupying only 10 hectares (105 m2). Besides its cost, efficiency, and area advantages com-pared to pumped hydro, MAPS does not have the major environmental problems of pumped hydro – large lakes, effect on wildlife, etc. – enabling it to be much more easily sited at a much wider range of locations.

Maglev can store thousands of megawatt hours of electrical energy from variable wind and solar power sources and baseload power plants, to meet peak power demands. Com-pared to pumped hydro, maglev storage costs much less, 2 cents per kilowatt hour (KWH) and has much greater efficiency, with an output/input power ratio greater than 90%. The MAPS (Maglev Power Storage) System stores electrical energy by moving heavy, e.g., 100 tonne, concrete blocks from a lower to a higher elevation, using the LSM (linear synchronous motor) propulsion system in the motor mode. Electric power is delivered back to the grid by moving the blocks downhill, with the LSM system operating in the genera-tor mode. In pumped hydro, pumps push the water uphill to store energy, and generate power by letting the water flow downhill through the pump units operating in the turbine mode. In MAPS, the concrete blocks are moved up and downhill on magnetically levitated and propelled sleds that travel on an on-grade guideway loop between upper and lower storage yards.

The Maglev sleds are simple inverted U-shaped structures that straddle the on-grade monorail. Superconducting quadrupole magnets on the vertical sides of the sled magnetically interact with iron lift plates and null flux aluminum loops on the monorail beam. Most of the levitation force is generated by the iron lift plates, while the null flux loops provide inherent vertical and lateral stability for the sled.

MAPS can be sited in both hilly terrain, using on-surface guideways, and in flat terrain, using underground slant tunnels. The MAPS technology is described in detail, together with a MAPS reference design for a 1000 megawatt hour storage facility that can quickly handle highly variable power inputs and output demands. MAPS can be readily scaled for both higher and lower storage capability.
