By Ivan Penn, The New York Times. [https://www.nytimes.com/2018/09/26/business/energy-environment/zinc-battery-solar-power.html 0] For GSS Energy Use chapter 9. Excerpt: Lithium-ion batteries have become essential for powering electric cars and storing energy generated by solar panels and wind turbines. But their drawbacks are also by now familiar: They use scarce minerals, are vulnerable to fires and explosions, and are pricey. A plentiful, safe and more affordable alternative would be worth a lot. On Wednesday, an energy company headed by the California billionaire Patrick Soon-Shiong announced that it had developed a rechargeable battery operating on zinc and air that can store power at far less than the cost of lithium-ion batteries. ...NantEnergy, based in Phoenix and in El Segundo, Calif., says it expects to expand the use of its product in telecommunications towers and eventually extend it to home energy storage, beginning in California and New York. Beyond that, it anticipates use in electric cars, buses, trains and scooters. ...Dr. Soon-Shiong said the cost of his zinc air battery had dropped steadily since development began. NantEnergy says the technology costs less than $100 per kilowatt-hour, a figure that some in the energy industry have cited as low enough to transform the electric grid into a round-the-clock carbon-free system. The prevailing cost of lithium-ion technology varies, depending on the scale and application. Yogi Goswami, distinguished university professor and director of the Clean Energy Center at the University of South Florida, estimated that it is most likely $300 to $400 a kilowatt-hour....
