“…[New] energy will be the fastest-growing U.S. energy source through 2050…[Three emerging technologies could make it less] expensive to store energy…[H]igh-capacity batteries with long discharge times – up to 10 hours – could be valuable for storing solar power at night or increasing the range of electric vehicles…[U]pwards of 100 gigawatts’ worth of these batteries will likely be installed by 2050…[T]hat’s 50 times the generating capacity of Hoover Dam…One of the biggest obstacles is limited supplies of lithium and cobalt…
Scientists are working to develop techniques for recycling lithium and cobalt batteries, and to design batteries based on other materials…[Because electrolytes in batteries often contain flammable materials, scientists] are developing solid electrolytes, which would make batteries more robust…[All-liquid designs called flow batteries allow] for super-fast charging and makes it easy to make really big batteries…[Molten salt can be heated with New Energy and stored] to heat steam and drive a generator in traditional plants…
[To make molten salts more efficient, researchers] are working to develop new salts or other materials that can withstand temperatures as high as 1,300 degrees Fahrenheit (705 C)…[Storing a lot of energy for indefinite amounts of time] is a role for renewable fuels like hydrogen and ammonia…[Surplus New Energy would be stored in hydrogen and ammonia, which] contain more energy per pound than batteries…[It] could be used for shipping heavy loads and running heavy equipment, and for rocket fuel…[I]t is possible to make hydrogen fuel by splitting water molecules using electricity. The key challenge is optimizing the process to make it efficient and economical. The potential payoff is enormous: inexhaustible, completely renewable energy.” click here for more
