Abstract
A method for subsurface hydrogen storage and hydrogen retrieval. The method includes identifying a subsurface formation, wherein the subsurface formation is selected from one or more of a depleted wet reservoir, depleted dry reservoir, salt cavern, excavated cavern, natural formation, isolated aquifer, or a reservoir designated as a contingency or marginal field. The method further includes selecting a liquid organic hydrogen carrier (LOHC) feed compatible with the subsurface formation. The LOHC feed includes a mixture of one or more completely or partially hydrogenated LOHCs. The LOHC feed is injected into the subsurface formation for storage. Later, when needed, the LOHCs are recovered from storage, optionally separating a recovered water/brine phase and off gas from the LOHCs from storage in a separator configured to produce a stream of recovered LOHCs. The LOHC is then dehydrogenated to form a H2 product and dehydrogenated LOHCs in a dehydrogenation unit process.
