The scientific paper “Fundamental hydrogen storage properties of TiFe-alloy with partial substitution of Fe by Ti and Mn” has been published on the Journal of Alloys and Compounds, 159925. The paper investigates the thermodynamic changes induced by the variation of Ti content along the homogeneity range of the TiFe phase (Ti:Fe ratio from 1:1 to 1:0.9) and of the substitution of Mn for Fe between 0 and 5 at.%. The results show dependence of hydrogen storage properties as a function of over an extended Ti and Mn compositional range.

The results derives from the research performed by HyCARE researchers Dematteis, Dreistadt, Capurso, Jepsen, Cuevas, and Latroche to define the optimal alloy composition for the HyCARE hydrogen storage system.

Fermin Cuevas (CNRS) hold a webinar on the HyCARE research activity related to TiFe intermetallics for large-scale stationary hydrogen storage. The webinar involved 15 students of the Master de Energías y Combustibles para el Futuro, Universidad Autónoma de Madrid.

The webinar presented the HyCARE project and described the tailoring and optimization of the allow composition for hydrogen storage performed by CNRS. It explained the R&D activities which inlude alloy design, tuning to thermodynamic operational conditions, activation and kinetic issues, as well as cycling stability, resistance to impurities and limited use of raw critical materials.
