Milder, faster, stronger, better! The cover shows a conceptual hydrogen battery in which H2 storage and its release are achieved through reversible catalytic hydrogenation of CO2 with an Ru-PNP pincer complex. In their Communication on p. 1526 ff., E. A. Pidko et al. describe a homogeneous catalytic system that shows unprecedented activity in both CO2 hydrogenation and dehydrogenation of HCO2H. The authors describe a key role of the base promoter on the reaction mechanism, the overall performance of the system, and its H2 storage capacity.
