Why Rust Batteries May Be the Future of Energy – Iron Air Battery Technology

While renewable energy sources like solar and wind have now become cheaper than fossil fuels, developing long-term energy storage is key to overcome their intermittency. Lithium-ion batteries are the state-of-the-art battery technology but they can only cost-effectively provide energy for about 6 hours. So, what if we could extend the battery duration to 100 hours … out of thin air … and rust? Literally!
