Splitting hydrogen just got cheaper

Hydrogen-powered cars may soon become more than just a novelty after a UNSW-led team of scientists demonstrated a much cheaper and sustainable way to create the hydrogen required to power them. In research published in Nature Communications, scientists from UNSW Sydney, Griffith University and Swinburne University of Technology showed that capturing hydrogen by splitting it … Continue reading Splitting hydrogen just got cheaper
