Clean water and clean air project (fresh water): method of energy storage and production of chemicals for water treatment

Abstract

An energy transport and storage system in combination with a method of water treatment, which includes: a fresh water or effluent water interconnection, an electricity interconnection with an electric grid, a water filtration and de-mineralization system, a fresh or effluent water electrolyser, a heat recovery system connected to the electrolyser, an electrolyte recovery system connected to the electrolyser, an interconnection to an alternative hydrogen gas supply, a high pressure underground hydrogen gas storage system, a safety valve connected to the underground hydrogen gas storage system, an electric generation system powered by compressed hydrogen gas turning a turbine during decompression which can recycle electricity within the system or send electricity to an electric grid, a hydrogen gas outlet for distribution of hydrogen, an oxygen gas transport system which sends oxygen gas to a water treatment facility to be used for water disinfection.

1 . A system for fresh or effluent water comprising: a fresh water or effluent water interconnection, an electricity interconnection with an electric grid or electric generation facility, a water filtration and de-mineralization system, a fresh or effluent water electrolyser, an electrolyte recovery system connected to said electrolyser, a heat recovery system connected to said electrolyser, an interconnection to an alternative hydrogen gas supply, a high pressure underground hydrogen gas storage facility, an underground storage well for hydrogen gas, a safety valve connected to said underground storage well for hydrogen gas, an electric generation system powered by compressed hydrogen gas and a turbine, a hydrogen gas outlet, an oxygen transport system for use with burning solid waste produced at a water treatment facility, and an oxygen gas transport system for use in creating ozone gas for use at a water treatment facility. 
     
     
         2 . The system of  claim 1 , further comprising a water interconnection between the system of  claim 1  and a water supply. 
     
     
         3 . The system of  claim 1 , with said electrolyser being of high or low pressure. 
     
     
         4 . The system of  claim 1 , with said electrolyser further comprising a self-contained electrolyte recovery and regulation system. 
     
     
         5 . The system of  claim 1 , with said electrolyser further comprising a system to manage and remove remaining electrolytic compounds. 
     
     
         6 . The system of  claim 1 , with said facility for underground storage of hydrogen gas further comprising a large air compressor or multiple air compressors in combination with a large heat exchanger or multiple heat exchangers. 
     
     
         7 . The underground storage facility for underground storage of hydrogen gas of  claim 6 , further comprising an empty petroleum or natural gas well, an empty salt mine, an empty aquifer, or other artificial or natural empty underground well. Said underground storage facility may be reinforced by concrete above and below ground. 
     
     
         8 . The underground storage facility for underground storage of hydrogen gas of  claim 6 , further comprising a safety valve located apart from the main production facilities. 
     
     
         9 . The underground storage facility for underground storage of hydrogen gas from  claim 6 , further comprising an outlet for hydrogen gas for distribution.
