The article explores the transformation of industrial waste gases, rich in carbon monoxide (CO), into hydrogen (H2) as a sustainable energy source. Key industrial sectors like iron and steel, oil refineries, and coal-fired power plants produce substantial waste gases containing CO. By harnessing the untapped potential of converting CO to H2 through the water gas shift reaction, a significant opportunity arises to address both energy needs and environmental concerns. The study estimates that 249.14 million tons of CO can be converted into approximately 17.44 million tons of hydrogen annually. This highlights the vast potential for hydrogen production from waste industrial streams, paving the way for improved waste management practices and a shift towards a more sustainable and circular economy. Furthermore, the article emphasizes how this process aligns with Sustainable Development Goals 7, 9, and 13, focusing on energy access, industry innovation, and climate action. Overall, the research underscores the transformative impact of utilizing hydrogen from industrial waste gases to propel towards a greener and more efficient industrial landscape.
