- Title
... and CO2 captured in stationary energy storage battery.
- Abstract
Researchers at Oak Ridge National Laboratory (ORNL) have developed and tested two different formulations for stationary batteries that can utilize CO2 from industrial sources while storing energy from renewable sources like wind turbines and solar panels. The batteries consist of two electrodes in a saltwater solution and pull atmospheric CO2 into their electrochemical reaction, releasing valuable byproducts. The batteries can be designed to remove these byproducts for use in other industrial processes. One formulation uses a sodium-CO2 battery with an inexpensive iron-nickel catalyst, while the other uses an aluminum-CO2 battery that can operate for over 600 hours without losing capacity and captures almost twice as much CO2 as the sodium-CO2 battery. The researchers are working on improving the batteries for scale-up.
