Hydrogen energy is essential to building a sustainable society with net zero carbon emissions in the face of global climate change and the energy revolution. Hydrogen generation begins with most Power-to-X methods that shape the future energy market. Electrolysis systems that use water/steam to make hydrogen have their own benefits and downsides.
One of the potential hydrogen generation technologies that can guarantee the future of a sustainable hydrogen economy is biohydrogen from biomass fermentation pathways. The notion of “zero waste” has been the subject of several recent investigations.
Traditional recycling methods may not be directly applicable, necessitating new technologies capable of efficiently recovering valuable materials. These efforts are crucial for minimizing waste, reducing the demand for virgin materials, and lessening the environmental impact of battery production .
