Highly efficient and stable Ru-free catalyst for hydrogen generation from ammonia

Green Car Congress

Although the thermocatalytic ammonia decomposition reaction (ADR) is an effective way to obtain clean hydrogen, it relies on the use of expensive and rare ruthenium (Ru)-based catalysts, making it not sustainable or economically feasible. A complete ammonia conversion to hydrogen was achieved at an economically feasible 450 ?C

Researchers split seawater without pre-treatment to produce green hydrogen

Green Car Congress

Researchers from the University of Adelaide and Tianjin University have successfully split seawater without pre-treatment to produce green hydrogen. A paper on the work is published in Nature Energy. The use of vast amounts of high-purity water for hydrogen production may aggravate the shortage of freshwater resources.

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”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.
