Abstract

Among the renewable energy resources in focus on the current climate change scenario, hydrogen energy is expected to play an important role for a sustainable energy economy. Hydrogen is an efficient energy vector for energies produced from renewable and environmentally clean sources, such as solar energy and wind power. Despite the hydrogen economy holding a promising prospect for a more environmentally friendly energy sector, the safe and economically viable transition to the hydrogen-based economy is highly dependent on hydrogen storage. Among the hydrogen storage methods currently investigated, metal hydrides (MHs) have been considered as a great alternative for solid-state hydrogen storage, providing reversibility, safety, and high volumetric densities. In this scenario, multicomponent alloys have been widely studied since their vast compositional space allows the tuning of the hydrogen storage properties of MHs. Furthermore, the Laves phases are known to reversibly absorb considerable amounts of hydrogen under moderate conditions of temperature and pressure and with good kinetics. In this context, the present research project aims to produce, characterize the structure, and evaluate hydrogen storage properties of the (TiZrNb)1(MnCr)2 alloy with C14-type Laves phase structure.
