A hybrid vertical energy storage system is invented wherein the components responsible for the conversion, storage and production of energy are used as the weighted component of a gravitationally aided energy storage device. The present invention allows gravity to operate mechanical devices which may help move a volume of fluid in order to compress a gas and store potential energy. The present invention utilizes the attributes of pumped hydro by using gravity assisted fluid transfer, and also combines Compressed Air Energy Storage (CAES) functionality by powering hydraulic pumps and motors to transfer fluid from one vessel to another vessel. This feature allows conventional, inexpensive, market proven components to make the capture, conversion, storage and production of energy more effective and affordable while eliminating the placement issues associated with such large scale pumped hydro and CAES systems while extending battery service life. Ideally, combining the positive attributes of some or all of the existing technologies into one energy storage system would provide a real and meaningful improvement, especially if the improvement reduced or eliminated economic, environmental and operational flaws associated with the individual technologies. This invention also provides a method of combining the output of individual, combined attribute energy storage systems to provide user definable and expandable electrical energy production. The vertical aspect of the invention allows operational attribute that separates and makes independent the capture and storage of energy being placed into the energy storage system and the hydro-pneumatic production of energy exiting the system.
