Iron-to-rust cycle tapped by scientists for safe renewable energy transport
SMRTR summary
Scientists at Germany's Karlsruhe Institute of Technology found that iron powder can store and transport renewable energy by burning it for electricity, then using green hydrogen to convert the rust back into iron. Existing coal plant infrastructure can be reused, making the switch cheaper and faster than building entirely new systems.
