Life Cycle Assessment of TiFe Hydrogen Storage Alloys: Effects of Storage Performance, Alloy Chemistry, and Circularity

This dataset supports the study “Life Cycle Assessment of TiFe Hydrogen Storage Alloys: Effects of Storage Performance, Alloy Chemistry, and Circularity”. It contains the foreground life cycle inventory data, alloy composition and hydrogen-storage performance parameters, energy and hydrogen inputs for alloy production and activation, recycled-content scenarios, Circular Footprint Formula parameters, and processed life cycle impact assessment results used in the manuscript and Supporting Information. The data are provided in spreadsheet format together with explanatory notes describing the variables, units, functional units, modelling assumptions, and scenario definitions. Results are reported for TiFe₀.₈₀X₀.₂₀ alloys, where X = Al, Cu, Cr, or Co, considering both primary and secondary material production routes and functional units based on reversible and maximum hydrogen storage capacity. Background life cycle inventory data obtained from ecoinvent are not included because they are subject to licensing restrictions. The deposited files therefore contain only author-generated foreground data, model parameters, scenario calculations, and processed results that can be legally redistributed. Users wishing to reproduce the full life cycle assessment must have access to the relevant ecoinvent datasets and to compatible LCA software.
