Hydrogen, a clean and sustainable energy source, is gaining attention for its potential in the green energy industry. Ammonia, with its high hydrogen content and ease of transportation, is emerging as a promising hydrogen carrier. However, its high-temperature requirements for decomposition have been a hindrance to its practical application as a green hydrogen source. A team of Japanese researchers from Waseda University and Yanmar Holdings collaborated to address this challenge. They introduced a novel method that leverages surface protonics and a Ru/CeO₂ catalyst, assisted by an electric field, to efficiently decompose ammonia to green hydrogen at lower temperatures. By applying this innovative approach, the team achieved nearly 100% conversion of ammonia to hydrogen at 398 K, exceeding equilibrium rates. The use of an electric field promoted surface protonics, reducing activation energies and facilitating the ammonia conversion reaction. This breakthrough not only demonstrates a more sustainable pathway for green hydrogen production but also signifies a step towards widespread adoption of clean alternative fuels. The research, published in Chemical Science, showcases the potential to accelerate the shift towards a greener and more environmentally friendly energy landscape.
