A method and system are provided to recover water and carbon dioxide from combustion emissions. The recovery includes, among other things, electrolysis and carbon dioxide capture in a suitable solvent. The recovered water and carbon dioxide are subject to reaction, such as a catalytic methanation reaction, to generate at least methane.

Devices, systems, and methods for power plant facilities are disclosed herein. A power plant facility includes a gas turbine; and a power generator that generates electricity from power supplied by the gas turbine. The power plant facility can also include at least one post-combustion capture unit that generates a CO2-rich stream from the combustion products of the gas turbine; and a sequestration compression unit that compresses and conveys at least one CO2-rich stream from a post-combustion capture unit, towards a sequestration site.

Disclosed herein are emission treatment systems comprising an oxidation catalyst composition in fluid communication with an exhaust gas stream emitted from an engine that combusts both hydrocarbon fuel and hydrogen; and optionally, at least one selective catalytic reduction (SCR) composition and/or at least one three-way conversion (TWC) catalyst composition, combustion systems comprising the same, and method of treating an exhaust gas stream, such as, e.g., an exhaust gas produced by combusting hydrogen fuel during a cold-start period, using the same.

A process and/or system for producing fuel using renewable hydrogen having a reduced carbon intensity. The renewable hydrogen is produced in a hydrogen production process comprising methane reforming, wherein at least a portion of the feedstock for the hydrogen production process comprises upgraded biogas sourced from a plurality of biogas plants. Each of the upgraded biogases is produced in a process that includes collecting biogas comprising methane and carbon dioxide, capturing at least 50% of the carbon dioxide originally present in the collected biogas and producing the upgraded biogas. Storage of the captured carbon dioxide reducing a carbon intensity of the fuel, without having to provide carbon capture and storage of carbon dioxide from hydrogen production.

Provided is a composition for removing a sulfur-containing compound contained in at least one of a liquid and gas, the sulfur-containing compound being at least one selected from the group consisting of hydrogen sulfide and an —SH group-containing compound, the composition containing an aldehyde and an amine whose conjugate acid has a pKa value of 11.3 or higher in water at 25° C.

A system that can eliminate engine combustion emissions in addition to raw and fugitive methane emissions associated with a gas compressor package. The system may comprise an air system for starting and instrumentation air supply; electrically operated engine pre/post-lube pump, compressor pre-lube pump, and cooler louver actuators; compressor distance piece and pressure packing recovery system; blow-down recovery system; engine crankcase vent recovery system; a methane leak detection system; and an overall remote monitoring system.
