Question

Note to players: Description acceptable. One technology for this purpose has an “advanced adiabatic” variant that has yet to achieve viability. Various devices that serve this purpose can be compared using a Ragone plot. (-5[1])One type of device used for this purpose relies on the formation of a double layer on two coatings of activated carbon and is called an EDLC. Another system for this purpose uses magnetic bearings to levitate a (*) flywheel. Round-trip efficiencies between 70-80% are achieved by “pumped” systems for this purpose, which hold water at two different elevations to deal with load fluctuations. Technologies for this purpose (10[1])are needed because, for many renewables, peak demand and peak production (10[1])occur at different times. For 10 points, name this process performed by hooking up a power plant to a grid of rechargeable batteries. ■END■ (10[1])

ANSWER: energy storage [accept answers indicating that energy or power or electricity or charge is being stored or saved for later use; accept grid energy storage or advanced adiabatic compressed air energy storage or flywheel energy storage or pumped hydroelectric storage; accept load balancing or load matching before “load”; prompt on load balancing or load matching after “load”; prompt on charging a battery or supercapacitor]
