EnergySystems can assure Uninterruptable Power Supply of electric Energy,
with chemical Energy-Storage and -Conversions to+from Hydrogen and Oxygen.
This can likely be a best chemical basis for sustainable use of natural Energy,
to convenient supply to demand-periods like night-times and to store Energy
during excess-availability periods (e.g. during daytimes) to refill gasStorage's.
This Energy-storage and -accessability also can benefit to portable needs.

A larger  Energy System installation  can comprise such gES and eES units (or a cESy) with GS_E energy storage.

Pure water (H2O) will be recycled, liquid contained from it's storage bladder under ambient pressure (about 0.1-to-1MPa); Pumped into the high pressure electrolysis elements to 42MPa; It is separated there by the electrical current applied within special solid electrolyte polymer membrane assemblies, into Hydrogen and Oxygen gasous pressurized available to 40MPa. Thus it can be fed directly to be separate stored in pressure vessels at pressures between about 2MPa and 40MPa and to be efficient fast transfer- and useable. Decompressed controlled to 2MPa, this Oxygen and Hydrogen gas is convertable back into electrical energy and water. This same excess water is then fed back into the water storage containment, in a closed circuit that can be unlimited and simultaneous repeated without losses except conversion and pumping energy that is necessary and the process-inherent termal excess heat that can be re-useable or can be vented to the external environment. The separate storage of gaseous Hydrogen and Oxygen to high pressures is convenient and safe, especially redundant cascaded banked it assures durable+efficient high-availability.

The hermetic closed fluid circuit of water and it's gaseous components Hydrogen and Oxygen,
assures the best safety against internal contamination. "Poisoning" of such oil-less clean active
thinFilm-Membranes, catalytic and electrode materials contained, can definitive be prevented.
Intrinsic safe defined prerequisites result to exceptional operational reliability and to a long life.
Due to this hermetic concept and functional design, JT-ESy components do not require external
air, nor compressors, nor disposable filters also,  it is an ecologic compatible inert-like system.
With multiple protective measures, installed easy operational and secure accessable in an inert
environmental assured 19"rack containment, it's utmost humane and ecologic safe solutions.
 

Advantage

+  multi-redundant modular inherent good operational-availability, -reliability and -security +  easy  simple handling and low maintenance with flexible extendability is user-ergonomic  +  high specific storage density due to high pressures and lightweight small peripheral parts +  long-term high-reliable operational life expectancy of installations also can be very economic +  good standby storage retention without any "memory effects" allows an efficient availability +  exact storage capacity estimate from pressure level read-out is an additional user assurance +  decentral scalable, modular Energy supply Systems can assure a better useful UPS-security +  direct renewable solar energy utilization will be supported ecologic inert safe and effective +  ecologic and human-social-economical e.g. health-cost-reduction benefits can be induceable

Disadvantage

-  compareable high up-front investments for system components that are long-term useful -  only in non-freezing environments install-, store- and transportable it's use will be limited -  except to few special sESy-generator modules, it's for terrestrial use to be stationary installed -  operational contingencies concerning positioning, gravity, temerature and use limits warranty
