Dozens of old e-car batteries form large power storage in port of Hamburg
A project in Hamburg combines dozens of old e-car batteries to form a large power storage plant in the city’s industrial port, industry newspaper THB reports. Carmaker BMW, Bosch and energy company Vattenfall jointly operate the project, called Battery 2nd Life, which uses over 100 out-dated but still functioning car batteries to regulate the power grid. The plant can contribute about 2 megawatts (MW) of capacity to the 600 to 700 MW needed to keep Germany’s grid balanced when electricity supply and demand fluctuates, THB writes. The batteries are given an additional lifespan of 10 years before being retired for good.
