Systems and methods for treating automotive vehicle emissions on board an automotive vehicle include the use of waste heat recovery, electrochemical water splitting, phototcatalytic water splitting, and selective catalytic reduction. Waste heat recovery is used to power electrochemical water splitting, or photocatalytic water splitting. Photons collected from a solar panel are used in photocatalytic water splitting, or in photo-assisted selective catalytic reduction. Hydrogen gas generated by water splitting is used in conjunction with catalytic reduction units to catalytically reduce NOx in an engine exhaust gas.

Systems, methods, and apparatuses for adaptive regeneration of aftertreatment system components. The system may include an aftertreatment system and a controller. The controller is configured to access one or more parameters indicative of an ambient condition, determine a regeneration type of a regeneration process for a component of the aftertreatment system, determine an application in condition, and modify a parameter for the regeneration process for the component of the aftertreatment system. In some instances, the controller initiates the regeneration process. In some instances, the one or more parameters include an ambient air temperature, a reductant tank temperature, or a particulate matter sensor temperature. In some instances, the modified parameter includes a target regeneration temperature, a regeneration duration, a dwell time between regeneration process, a threshold value for the regeneration process, or a minimum regeneration temperature.
