I have mentioned metal hydride storage schemes, complex hydrated polymers and hydro-carbon liquids with carbon from the biosphere.
None are widespread in use, but all are viable storage schemes.
One idea is to extend the work of a company called Hythane. Basically they are mixing 10% hydrogen gas by volume with methane (though a much higher percentage of hydrogen could be used). The affinity of hydrogen to the carbon atom through the weak molecular bond keeps the hydrogen from migrating into the metal containers. The methane could be composed of producer hydrogen with the carbon from biosphere sources. The mixture is easily transported, as now, in the natural gas pipelines we have in existence. The energy can be used in both natural gas vehicles and stationary uses.
