•Porous hydrogels particles (HP) enhance reversible methane storage.•High storage capacity requires high water contend in HP and suitable water-HP ratio.•Stable porous structure and mild operation pressure improve the reversibility. Porous hydrogel particles of poly(2-hydroxyethyl methacrylate) (PHE...
