Hydrogen, with its high energy density and eco-friendly attributes, is gaining recognition as a key element in achieving a sustainable future. While hydrogen is abundantly found in nature, its extraction from compounds like ammonia often requires high temperatures, limiting its practical applications. In a groundbreaking study led by Professor Yasushi Sekine and his team at Waseda University, a new method was developed to produce green hydrogen from ammonia at lower temperatures. By leveraging a Ru/CeO2 catalyst and applying a DC electric field, the researchers successfully demonstrated a significant increase in the rate of ammonia-to-hydrogen conversion, even below 473 K. The key innovation in this approach is the utilization of surface protonics to reduce the activation energy needed for ammonia decomposition, leading to enhanced efficiency in hydrogen production. Through experimental and theoretical investigations, the team confirmed the efficacy of their strategy, achieving 100% conversion of ammonia at 398 K. This breakthrough not only offers a more sustainable pathway for hydrogen generation but also opens doors for the seamless adoption of clean energy alternatives. The collaboration between academia and industry, particularly with Yanmar Holdings, highlights the practical implications of this research in advancing the use of green hydrogen as a viable fuel source for various applications.
