In order to uphold today�s standards of living and secure a future sustainable environment, alternatives to fossil fuels as resources for both energy and chemicals need to be developed. A promising solution for both areas is the use of biomass as feedstock for chemical basis compounds and to deliver hydrogen as stored energy.Here, we present the newest achievements in hydrogen generation from (bio)ethanol, which constitutes the most effective system today. For this, we use a novel pincer-ligand based HPNPiPr/Ru(II) catalytic system that operates very efficiently below 100oC and with no additives needed. A maximum turn-over frequency (TOFmax) of ca 1500 h-1 is obtained. Moreover, for the model substrate isopropanol, a TOFmax of >14000 h-1 was acheived. This should be compared with previous state-of-the-art that showed a TOF around 500 h-1.
