Hydrogen, a crucial element in the industrial economy, faces supply chain challenges as most of it is derived from natural gas or gassified coal. However, the emergence of sustainable 'green hydrogen' sources is gradually reshaping this landscape. Biochar, a carbon-rich material derived from organic waste or biomass, is gaining attention for its soil enhancement properties. The USDA highlights biochar's ability to sequester carbon in soils for extended periods, offering various environmental benefits such as improving soil health, sequestering carbon, and lowering greenhouse gas emissions. In recent years, biochar has also been explored for applications in green hydrogen production. Researchers are leveraging biochar-assisted water electrolysis to enhance the efficiency of hydrogen production processes. Studies from institutions like the University of Shanghai and the University of Illinois - Chicago have shown promising results, indicating significant energy savings and advancements in solar-powered hydrogen production. Despite the carbon emissions involved in biochar production, researchers are considering innovative solutions like carbon capture to mitigate environmental impacts. Overall, the intersection of biochar and green hydrogen presents a transformative pathway towards sustainable energy solutions, with the potential to revolutionize the renewable energy landscape.
