Abstract: A system is disclosed that includes an exhaust duct assembly coupled to a locomotive producing locomotive exhaust and coupled to a capture car, the capture car housing a generator, an aftertreatment system, a mixing valve, and a controller. The mixing valve is in fluid communication with the exhaust duct assembly, the generator, the aftertreatment system, and the atmosphere. The controller is configured to receive a first signal indicative of a system condition and to cause the mixing valve to direct an output gas (locomotive exhaust and/or generator exhaust) through to the aftertreatment system and/or the atmosphere. The system condition can be a gas temperature, a backpressure condition, and/or a condition indicating whether a system component is active or inactive.

Abstract: A system for mobile carbon capture, preferably including a capture module, a regeneration module, and a storage module 130. The system can optionally include a thermal control module and/or a dehumidifier. A method for mobile carbon capture, preferably including adsorbing a target species, desorbing the target species, and storing the target species. The method can optionally include pre-treating input gas, offloading stored species, and/or regenerating desiccators.

Abstract: A method and conditioning system for conditioning exhaust gas are provided. The conditioning system includes one or more heat removal systems for removing heat from an exhaust gas. The conditioning system also includes a condensate removal system fluidly coupled with, and positioned downstream of, the one or more heat removal systems. The condensate removal system is operable to remove moisture from the exhaust gas. In some variants, the conditioning system further includes one or more fluid chambers fluidly coupled with, and positioned downstream of, the condensate removal system. Each fluid chamber defines an interior in which a capture medium is contained. The cooled, moisture-depleted exhaust is selectively distributed to the fluid chambers to allow for harvesting or capture of a set of target species from the exhaust gas.

Abstract: The fluid chamber system can include: a chamber housing, a capture medium, an internal support structure, and/or any other suitable components. The system can optionally include a thermal management system. However, the system can additionally or alternatively include any other suitable set of components. The system preferably functions to direct an input fluid (e.g., vehicle exhaust) through the capture medium and/or harvest one or more target species (e.g., carbon dioxide) from the input fluid (e.g., vehicle exhaust).

Abstract: A vehicular vessel mounting system is provided. In one aspect, a vehicular vessel mounting system includes a mount arranged to support a pressure vessel in a substantially vertical orientation. The mount includes a vertically oriented spine and a backing connected to the spine. The backing is shaped to match an outer wall of the pressure vessel. One or more retention mechanisms are arranged to retain the pressure vessel to the backing.
