Using the Ocean for Future Energy Storage

file photo Electric utilities of many nations operate hydroelectric energy storage batteries that are recharged overnight by pumping potable water uphill and then delivering peak-hour daytime electric power. Drought and increasing populations in many nations increases the attractiveness of using seawater to store energy. Pumped Storage Many nations operate hydroelectric power generation that includes upper and lower reservoirs. A grid-scale energy storage battery that holds several megawatt-hours of electric power compliments power generation technologies that produce when market demand is minimal. At Michigan, U.S., the Ludington pumped hydraulic energy facility uses overnight electric energy to pump water from Lake […]
