Although exploding smartphone batteries have captured public attention lately, utilities around the country are battling an even bigger battery challenge—the need to create storage, said experts at the fall Engineering Distinguished Lecture Thursday.

Increased generation of renewable energy—especially solar—is quickly changing the game for utilities. Previously, nonrenewable energy allowed utilities in the state to better synch power generation with use in keeping with the requirements of the California Independent System Operator, which manages energy flow for 80 percent of California.

Fall Engineering Distinguished Lecture Tackles Energy Storage

Fall Lecture graphicsThe Fall Engineering Distinguished Lecture will tackle a topic very much in the news: energy storage. While the overheating of lithium-ion battery in smartphones is currently receiving much attention, energy storage on a large scale is equally important.

The amount of electrical energy derived from photovoltaic and wind sources varies with time, day of the week, season, weather, and other factors. Electrical energy must be stored during times when production exceeds consumption, and returned to the grid when production falls below consumption. Large-scale electrical energy storage is the single most challenging issues that California faces as it moves toward more dependence on renewable sources.
