Looking for a way to store massive amounts of excess green energy? Water may provide the answer.
With lakes, pipes, and pumps, the Los Angeles Department of Water and Power essentially created a giant battery capable of storing enough energy to power more than 80,000 homes. The solution was necessary because the city is on a mission to cut fossil fuel use by 2045 and needed a way to harness the green energy produced during the day to offset gas and coal power used at night. A traditional battery couldn’t be built large enough to handle the task.
