The most obvious options are high pressure gas storage and making liquid hydrogen (LH2). For transportation fuel uses, compressed gas storage is the least bad of a terrible set of choices. However, even at 700 bar (10,000 psig or 5 tons per square inch of pressure), hydrogen is still only 41 kg/m3.
