Abstract
Prior research into methane storage as a solute gas dissolved in special blended hydrocarbon liquids, and recent developments in use of supercritical fluids as solvent replacements, disposed the inventor to create a novel form of hydrogen packaging by dissolution in a specially blended solvent maintained at specified temperature and pressure conditions at which intermolecular attractions and related critical region phenomena permit storing nine times as much dissolved hydrogen in a given volume than pure hydrogen at the same conditions. The solvent constituents selected are ethane and hexane respectively in a nine-to-one parts by weight ratio, and the solution is prepared and intended to be maintained in its packaged state at room temperature and from twenty to fifty atmospheres of pressure. The solution may be combusted in toto as a fuel, or, if desired, known means for separation of hydrogen may be applied so as to deliver pure hydrogen to a fuel cell.
