Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. The team first used chemical looping on coal and shale gas to convert fossil fuels into electricity without emitting carbon dioxide into the atmosphere.

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.

Conservation group opposing Thacker Pass lithium mine seeks endangered status for Kings River pyrg (snail)

Green Car Congress

In 2018, Lithium Americas completed a pre-feasibility study (PFS) on a two-phase project with a production capacity designed to reach 60,000 tpa of battery- quality lithium carbonate (Li 2 CO 3 ) and 46-year mine life. The sedimentary-clay deposit at Thacker Pass will use similar mining techniques to many coal deposits.

Rio Tinto validates BioIron process for low-carbon iron-making; biomass and microwave energy

Green Car Congress

The process, known as BioIron, uses raw biomass instead of metallurgical coal as a reductant and microwave energy to convert Pilbara iron ore to metallic iron in the steelmaking process. Accordingly, the company is undertaking a benchmarking study of biomass certification processes. Earlier post.)
