Ammonia decomposition for hydrogen economy, improvement in hydrogen extraction efficiency

For the implementation of an effective hydrogen economy in the forthcoming years, hydrogen produced from sources like coal and petroleum must be transported from its production sites to the end user, often over long distances and to achieve successful hydrogen trade between countries. Drs. Hyuntae Sohn and Changwon Yoon and their team at the Center for Hydrogen-fuel Cell Research of the Korea Institute of Science and Technology (KIST) have announced a novel nanometal catalyst, constituting 60% less ruthenium (Ru), an expensive precious metal used to extract hydrogen via ammonia decomposition.
