Energy Storage | MIT Climate Portal
The "Grid Level Energy Storage Problem" Solar and wind provide "intermittent" electricity, meaning their energy production changes depending on the weather. People often need energy when the wind is not blowing or the sun isn''t shining, so we can end up with too much electricity at some times, and not enough electricity at other times.
Energy storage systems: a review
Lead-acid (LA) batteries. LA batteries are the most popular and oldest electrochemical energy storage device (invented in 1859). It is made up of two electrodes (a metallic sponge lead anode and a lead dioxide as a cathode, as shown in Fig. 34) immersed in an electrolyte made up of 37% sulphuric acid and 63% water.
