The transition to a hydrogen-based economy necessitates the development of safe, cost-effective hydrogen storage media at an industrial scale. The equiatomic intermetallic titanium-iron (TiFe) alloy is a prime candidate for stationary hydrogen applications due to its high volumetric storage density, nontoxicity, and safety attributes. However, the conventional synthesis of TiFe alloy relies on high purity titanium and iron metal feedstocks, which must first be extracted from their respective ores before being alloyed in equiatomic ratio. This is a complex, multistep process posing environmental and economic challenges associated with the extraction of metallurgical-grade titanium. Here, we propose an alternate straightforward synthesis pathway for TiFe alloy through the direct calciothermic reduction of ilmenite sand (FeTiO
