This invention relates to a high-performance, low-cost water capacitive deionization and hydrogen electrolyzer system that can operate from AC or DC power sources and manage and store power when coupled with renewable energy sources.

A negative pressure aeration system, created by atmospheric siphon pressure above the waterline and mechanical pump suction below the waterline, which impedes the growth of organic matter. A waterfall flow in vacuum effect is created within a system that aerates the raw water as it falls through the air chamber of the system housing, which assists in the suppression of organic growth by reducing the contact surface area within the system. A chemical tank allows an anti-fouling chemical to be added to the entire system and a power supply allows flexible electrodes driven by a vacuum to create a further anti-fouling benefit throughout the components of the system.

An electrochemical deionization system that maintains an operating temperature range of a solution stream (e.g., seawater or brackish water) flowing through the cells of the electrochemical deionization system. Maintaining the operating temperature range is targeted at prolonging the lifetime of the system and increasing the overall performance of the electrochemical deionization system.

A water electrolysis system includes: a water electrolyzer configured to electrolyze water to generate gas including oxygen and hydrogen; a gas-liquid separator configured to separate gas phase including hydrogen from liquid phase of the gas generated by the water electrolyzer; a water level detector configured to detect a water level in the gas-liquid separator; a pressure detector configured to detect a pressure of the gas phase in the gas-liquid separator; and a CPU and a memory coupled to the CPU. The CPU is configured to perform: calculating an error of the water level in the gas-liquid separator detected by the water level detector based on the pressure of the gas phase in the gas-liquid separator detected by the pressure detector.

In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

An emissions clean-up process is provided to remove detrimental exhaust gases from a fossil fuel power plant and to produce and/or reclaim various useful commercial byproducts. The process includes mixing a blended liquid solution with a solubilizer in a mixing tank to create a chemical reaction therein to produce an ionic solid and an alkaline liquid solution. By mixing various blended solutions with desired solubilizers, alkaline liquids are produced which may be chemically combined to create other byproducts or sold commercially. Likewise, the alkaline liquids may be passed through a wet scrubber to create a byproduct that when chemically mixed with an acid creates desired byproducts. Other byproducts such as a sodium bicarbonate liquid solution exits the wet scrubber and is sold or used in the subject process to produce various other byproducts.
