Automotive fuel cells may one day rely on pure hydrogen fuel for toxic waste gases

According to a recent study from the Journal of the American Chemical Society, ACS Sustainable Chemical Engineering, converting hydrogen sulfide gas (fields, manure gases or sewage gases) into pure hydrogen fuel is effective, inexpensive, and relatively easy to implement. .

According to Lang Kin, a co-author of the study and a researcher in chemistry and biomolecular engineering at Ohio State University, iron sulfide can solve two problems by adding molybdenum as an additive.

Hydrogen sulfide is a particularly harmful gas used in industry and therefore makes it an ideal base material for use in toxic and costly processes.

They call it the SULGEN process, and it involves the use of pure chemical, metal sulfide for industrial use. But iron ore is not the only thing that works. Kin and his team set out to find cheaper chemicals that could be used to make a big difference. The answer may be the introduction of molybdenum into iron sulfide.

“Our research is very close to finding out if it can replace any of the existing hydrogen fuel technologies,” said Kalinini Jangam, author of the study and a graduate of the Ohio State Energy Research Laboratory. But what we are doing is correcting this decay process and producing a valuable product.

According to the study, molybdenum improves hydrogen sulfide degradation and is divided into two components – hydrogen fuel and sulfur.

Kin says the ‘big picture’ is the result of solving harmful gas issues and that the ‘chemical rotation’ process takes care of that problem.
