Ammonia (NH₃) can be decomposed to produce hydrogen gas without releasing CO₂. The ease of transport and high hydrogen density make it valuable for the green energy industry. A drawback of using NH₃ is that it requires very high temperatures for decomposition reactions. In an example of university-industry collaboration, a team of Japanese researchers presented a surface protonics-assisted method for the on-demand production of green hydrogen from ammonia using an electric field and Ru/CeO₂ catalyst.
