The rapid urbanization and growth in industrial sectors have led to a surge in energy demand globally, primarily met by fossil fuels. To combat the adverse environmental impacts of this reliance on fossil fuels, there is a growing urgency to decarbonize the energy sector and transition to sustainable energy sources. Developing economies, in particular, are increasingly recognizing the need to shift away from fossil fuels towards cleaner alternatives like biohydrogen. Biohydrogen production is seen as a promising solution to reduce carbon emissions and combat climate change. Investments in biohydrogen production are expected to increase significantly by 2050, with countries like Brazil, China, and India leading in the generation of biohydrogen from agricultural waste. Technological development policies play a crucial role in facilitating this transition towards low-carbon biohydrogen production. Studies show that different biochemical processes using various waste materials can yield biohydrogen, offering a sustainable alternative to traditional fossil fuels. Overall, the shift towards biohydrogen production presents a positive outlook for global energy sustainability and environmental preservation.
