MgH₂ has an overall hydrogen storage of 7.6 wt%, yet only in certain circumstances is full-capacity release/storage possible.

Thus, the effect of the PEG molecular weight (200–20,000 Da), PEG 200 concentration (0–5 wt%), and PSf concentration (14–24 wt%) in the casting solution on membrane properties are systematically investigated in this paper. Membrane morphology, porosity, bubble point, pure water flux (PWF), moisture content, and contact angle were analyzed. SEM analysis confirmed the formation of uniform nanoporous structures, particularly at 3 wt% PEG-200. The increasing PEG-200 concentration in the PSf membrane casting solution leads to enhanced PWF from 103 to 123 L m⁻² h⁻¹ and increased membrane hydrophobicity, as indicated by a rise in contact angle from 40.58° to 69.63°. Thus, the PSf membrane synthesized using the PEG-200 as a pore former shows the higher water flux compared to membrane prepared using PEG-400 or higher molecular weight PEG.
