A hydrogen sorbent composition comprising a hydridable material encradled throughout a fiber-containing polymeric material having interconnecting pores therethrough, said composition being developed from a substantially dry mixture of compatible and non-reactive components consisting essentially of: (A) a particulate hydridable material, a fibrillatable organic polymer and a major amount of removable pore-former, said pore-former being an organic polymer having a molecular weight of about 100,000 to about 1,000,000 and characterized in that it melts below the temperature at which any of the components of the mixture may react with each other, or (B) a particulate hydridable material, a fibrillatable organic first polymer, a support-contributing second polymer and a major amount of removable pore-former; said porosity of the composition being developed in the mixture of components on removal of the pore-former after fibrillation of the fibrillatable polymer, whereby accessibility to the hydridable material in the composition is maximized. A hydrogen sorbent composition, said composition being porous and comprising a hydridable material, discrete fibrils obtained from a fibrillatable first organic polymer, and a support-contributing second polymer, said hydridable material being distributed throughout the composition, and said composition being developed by processing of the components of the composition in the presence of a major amount of a removable pore-former and said porosity being developed on the removal of the pore-former, whereby accessibility to the hydridable material in the composition is maximized.
