Abstract: A hydrogen cooled pressure packer, systems, and methods of operation are provided. The pressure packer can include a flange portion and a plurality of packing cups coupled to the flange portion. One or more packing cups of the plurality of packing cups include at least one injection channel extending therethrough and terminating in at least one injection port. The pressure packer can also include a seal abutted with at least one packing cup of the plurality of packing cups. The pressure packer can be configured for use in a hydrogen compressor operable within a hydrogen vehicle refueling facility.

Abstract: A method for capturing carbon from a source of volatile pollutants includes the steps of capturing a mixture of volatile pollutants and air from the source of volatile pollutants, transporting the volatile pollutant-air mixture to an oxidizer module, converting the volatile pollutants into carbon dioxide within the oxidizer module, transporting the carbon dioxide from the oxidizer module to a contactor, loading the carbon dioxide onto sorbents within the contactor, and separating the carbon dioxide from the loaded sorbents to produce a concentrated carbon dioxide product stream. The step of separating the carbon dioxide from the loaded sorbents may optionally include the steps of passing the loaded sorbents to the oxidizer module, and then heating the loaded sorbents in the oxidizer module with the combustion of the mixture of volatile pollutants and air within the oxidizer module to produce the concentrated carbon dioxide product stream while regenerating the sorbents.

Abstract: Methods for determining mineral compositions of materials are described. The methods include obtaining elemental data associated with a geologic sample, calculating a measurement correlation matrix of the geologic sample from the elemental data, calculating an artificial correlation matrix, comparing the measurement correlation matrix and the artificial correlation matrix to determine an error value, minimizing the error value by updating the artificial correlation matrix and comparing the measurement correlation matrix to the updated artificial correlation matrix, and determining a mineral composition of the geologic sample based on the minimized measurement correlation matrix.

Abstract: A system and method of generating electricity. A work string extends into a wellbore. A heat pump unit at a surface location circulates a working fluid through the work string to absorb heat from a formation surrounding the wellbore. A turbine generates a rotation from the working fluid that has absorbed the heat. A generator generates electricity from the rotation of the turbine. The electricity is transmitted to the surface location via an electrical cable.
