A pressure vessel for storing hydrogen is described. The pressure vessel includes at least one chamber to store hydrogen atoms. The pressure vessel also includes a mycelium structure within the at least one chamber. The mycelium structure has a surface area of at least 800 m.sup.2/m.sup.3. At least some of the hydrogen atoms are attached to the mycelium structure at a pressure greater than ambient pressure. Methods of storing hydrogen and methods of constructing a hydrogen storage tank are also described.
