Transforming ‘sewer gas’ into clean hydrogen fuel

Posted by in categories: chemistry, energy, engineering, sustainability

Scientists have found a new chemical process to turn a stinky, toxic gas into a clean-burning fuel.

The process, detailed recently in the American Chemical Society journal ACS Sustainable Chemical Engineering, turns —more commonly called “sewer gas”—into . 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.

The process detailed in this study uses relatively little energy and a relatively cheap material—the chemical iron sulfide with a trace amount of molybdenum as an additive.
