Optimized alloy composition

Summary of deliverable D2.1. The increase in air pollution and global temperatures demonstrates how essential it is to look for alternatives to fossil fuels. The efficient storage of renewable energy would enable the transition towards CO2-free energy. Hydrogen can be produced from renewable sources and, as an efficient energy carrier, it can be stored for a long period. Metal hydrides are safe materials for solid-state hydrogen storage under mild conditions. At CNRS, an investigation to define the optimal hydrogen carrier composition was performed at the lab-scale. Different experimental techniques were used for the synthesis and characterisation of different substituted FeTi-alloys. Considering the goals of the project, reversible capacity, PCI, activation and cycling properties have been determined.
