An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.

A negative-carbon footprint concrete composition includes CO.sub.2-sequestering aggregate that sequesters carbon dioxide (CO.sub.2) from a CO.sub.2 containing gas and cementitious material. The negative-carbon footprint concrete composition has a negative carbon footprint relative to an ordinary concrete composition.

A method for reducing the concentration of amines in a wash liquid stream exiting a wash section in an acid gas scrubbing process includes introducing the wash liquid stream exiting the wash section of the acid gas scrubbing process to an adsorbent material, wherein the wash liquid stream has a first concentration of amines. The wash liquid stream having the first concentration of amines is flowed through the adsorbent material, and the adsorbent material retains at least a portion of the amines thereby providing a wash liquid stream having a second, reduced concentration of amines. The wash stream with reduced concentration of amines is recycled back to the wash section to remove amines more effectively from the acid gas being scrubbed. The adsorbent material can be regenerated for reuse. Amine recovered from the regenerated adsorbent material can be recycled to the process for reuse.

A method of forming a concrete product includes directly capturing CO.sub.2 from a gas source, the capturing comprising contacting the gas source with an absorption solution having a solvent and a solute, wherein the solvent and/or the solute are capable of reacting with CO.sub.2 to form an anionic compound, adjusting the pH of the absorption solution electrochemically to less than about 7 to release the CO.sub.2 as a concentrated vapor containing CO.sub.2, collecting the concentrated vapor containing CO.sub.2, regenerating the solvent and/or the solute, and optionally collecting the regenerated solvent and/or solute; flowing the concentrated vapor containing CO.sub.2 through a gas processing unit to adjust at least one of a temperature, a relative humidity, or a flow rate of the concentrated vapor containing CO.sub.2; and contacting the concentrated vapor containing CO.sub.2 with a concrete component.

A spacesuit contaminant removal system includes at least one membrane separator and a liquid sorbent circuit. The at least one membrane separator is configured to receive a spent air stream from a ventilation system of a spacesuit and absorb a contaminant from the spent air stream into a liquid sorbent. The at least one membrane separator is configured to discharge a clean air stream to the ventilation system and discharge the contaminant in a contaminant stream to a space environment using a vacuum of the space environment. The liquid sorbent circuit is configured to circulate the liquid sorbent through the at least one membrane separator.

A carbon dioxide recovery apparatus is disclosed including a flue gas cooling unit that brings flue gas cooling water into contact with a flue gas to cool the flue gas, a circulation channel through which the flue gas cooling water and condensed water are returned to the flue gas cooling unit, an absorption unit including a carbon dioxide absorbing section, and a flue gas washing section that brings the flue gas including carbon dioxide absorbed in the carbon dioxide absorbing section into contact with flue gas washing water and washes the flue gas, a regeneration unit that removes carbon dioxide from the absorbent including carbon dioxide absorbed in the absorption unit, a supply channel through which circulating water is guided, and a discharge channel through which the circulating water circulating through the flue gas cooling unit and the circulation channel is discharged to outside of a system.

A turbocharger control system includes a turbine; a fluid source of a pressurized fluid; an input valve fluidly coupled between the fluid source and an input of the turbine; a bypass valve fluidly coupled between the fluid source and an output of the turbine; a rotating machine operatively coupled to the turbine and configured to move a working fluid; and a control system communicably coupled to the input valve and the bypass valve. The control system is configured to perform operations including determining a level of the pressurized fluid in the fluid source; determining at least one of a flow rate or a pressure of a working fluid moved by the rotating machine; and operating the input valve and the bypass valve to change an operating state of the turbine from a first operating state to a second operating state.

A method and apparatus for purifying gas where gas is treated in a multistage treatment having at least two ejector stages, a motive medium including liquid, steam or gaseous agent at high pressure injected by an ejector of the ejector stage, and the gas is sucked into the same ejector and mixed with the motive medium for forming a mixture, at least a part of gas and/or liquid phase of the mixture is supplied to a second ejector stage having so that a second motive medium which includes liquid, steam or gaseous agent is injected to the ejector and the gas and/or the liquid phase is sucked into the same ejector in which the gas and/or liquid phase is mixed with the second motive medium for forming a second mixture, at least one of the mixtures includes an additive for removing impurities of the gas, and a purified gas is formed.

A reclaimer system and methods for using said reclaimer system to reclaim one or more amine agents from a fluid containing one or more degradation products that have been formed from the reaction of one or more acid gas components with the one or more amine agents.

Devices, systems, facilities, and methods for bio fermentation-based facilities, such as corn milling, ethanol, breweries, and biogas, are disclosed herein. The CO2 rich streams from the fermentation unit and the process heaters/boilers are sent to a sequestration site or pipeline via a capture unit and sequestration compressor, thereby reducing the overall emissions from the facility.
