Hydrogen Storage Small amounts of hydrogen (up to a few MWh) can be stored in pressurized vessels, or solid metal hydrides or nanotubes can store hydrogen with a very high density. Very large amounts of hydrogen can be stored in constructed underground salt caverns of up to 500,000 cubic meters at 2,900 psi, which would mean about 100
An energy dense and easily transportable fuel that can be moved through natural gas pipelines. There are certain benefits but it''s horribly inefficient. Hydrogen as a storage would also make economic sense in "grid-isolated" areas, e.g., islands which are not electrically connected to the mainland grid.
PHS Superiority: It became evident that Pumped Hydro Storage (PHS) holds distinct advantages over Hydrogen (H 2) storage in two critical areas: efficiency and environmental impact.

The novelty of this study in the field of HRESs is the combination of two different energy storage technologies, namely pumped-storage hydropower and
Consequently, efficient lithium ion would replace pumped hydro at high cycles, which in turn would become more competitive than compressed air and hydrogen storage at high discharge durations. The average share of charging cost in LCOS increases to 19% (35% across the 12 modeled applications) ( Figure S7 ).
Pumped hydro, on the other hand, allows for larger and longer storage than batteries, and that is essential in a wind- and solar-dominated electricity system. It is also cheaper for overnight

The idea for pumped hydro storage is that we can pump a mass of water up into a reservoir (shelf), and later retrieve this energy at will—barring evaporative loss. Pumps and turbines (often implemented as the same physical unit, actually) can be something like 90% efficient, so the round-trip storage comes at only modest cost.
