OSU team develops process to clean coal mine drainage and extract rare earth elements

Green Car Congress

Researchers at The Ohio State University have developed a novel process to clean coal mine drainage and extract rare-earth elements from it. Coal mine drainage (CMD) impairs tens of thousands of kilometers of U.S. CMD, coal mine drainage; TEP, trap-extract-precipitate. —Miranda et al. Miranda et al. 2021.0378.

OSU team demonstrates Coal-Direct Chemical Looping for more efficient and low carbon coal heat release

Green Car Congress

An Ohio State University team has demonstrated the successful operation of Coal-Direct Chemical Looping (CDCL)—which chemically harnesses coal’s energy and efficiently contains the carbon dioxide produced before it can be released into the atmosphere. Hot iron and coal ash are left behind. 2 millimeters across.
