Key aspects including ortho–para hydrogen isomerism, physisorption mechanisms, measurement methods, and adsorption metrics are discussed. Large variability in reported data arises from inconsistent reporting of adsorption type, measurement uncertainty, and hydrogen isomer composition. At 298 K, adsorption capacities remain low (<5 mmol/g), while at 77 K capacities increase substantially, with IRMOF-1 reaching ∼30 mmol/g.
