Clean water and clean air project (brine): method of water treatment, chemical production, and underground energy storage

Abstract

An energy transport and storage system in combination with a method of water treatment which includes: a brine (including ocean, sea, or estuary water) interconnection, an electricity interconnection with an electric grid, a filtration and demineralization system, a brine water electrolyser, a gas separation or filtration system, a heat recovery system connected to the electrolyser, a sodium hydroxide recovery system, 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 gas, a system to collect other gases, and a chlorine gas production system. This invention will produce clean water and clean air. This invention will provide clean water by using brine water to produce energy in the form of hydrogen, which is eventually converted back into fresh water, which can be used. Hydrogen gas produced from renewable energy can be combined with atmospheric oxygen to produce electricity, heat, and water. This energy creation and use process in the form of hydrogen creates virtually no pollution. This hydrogen energy use process is thus cleaner than the use of petroleum combustion technologies, which pollute air and water.
