Hydrogen storage in complex hydrides: past activities and new trends

Abstract Intense literature and research efforts have focussed on the exploration of complex hydrides for energy storage applications over past decades. A focus was dedicated to determination their thermodynamic hydrogen properties, due high gravimetric volumetric capacities, but application has been limited because harsh working conditions reversible release uptake. The present review aims at appraising recent advances different hydride systems, coming from proficient collaborative activities in years groups led by experts Task 40 ‘Energy Storage Conversion Based Hydrogen’ Hydrogen Technology Collaboration Programme International Energy Agency. An overview materials design, synthesis, tailoring modelling approaches, uptake mechanisms aspects are reviewed define new trends suggest possible these highly tuneable materials.
