The Search for Grid Energy Storage | EPRI Journal
By Brent Barker. Energy storage on the electricity grid has been around since the 1880s when Thomas Edison used lead-acid batteries to store power for the nighttime illumination peak. At the time, Edison''s direct current grid extended no more than a few city blocks in lower Manhattan, and nearly all the electric demand was for lighting.
