Researchers from the Instituto de Tecnología Química (a mixed centre of the Polytechnic University of Valencia and the Superior Council of Scientific Research – CSIC) have developed a new catalyst with which to obtain clean hydrogen of high purity and high energy efficiency from bioethanol. Hydrogen is a source of energy for the future due to its low environmental impact. The finding is a new step towards the sustainable production of hydrogen and its use in fuel batteries, amongst other application, buses, trains or trams.
