Abstract: A retrofit vehicle including a hybrid power plat in place of a carbon-fuel based power plant comprises a frame, a tray, a deck, a battery system, a gas storage system, and a fuel cell system. The tray is coupled to the frame and defining an open top configured to receive a load. The deck is coupled to the frame forward at least a portion of the tray and at least partially defining a deck volume to receive components of the hybrid power plant. The batty system is mounted to the vehicle. The gas storage system is installed in a volume of the vehicle. The fuel cell system includes at least a first portion installed in a first wheel pocket of the retrofit vehicle and a second portion installed in a second wheel pocket of the retrofit vehicle. The first wheel pocket is configured to contain a fuel tank prior to retrofitting the retrofit vehicle.

Abstract: A retrofit mining haul truck includes a hybrid hydrogen fuel cell/battery-based powerplant in place of a carbon fuel-based powerplant. The retrofit mining haul truck includes a frame, a tray coupled to the frame, and a deck coupled to the frame forward of at least a portion of the tray. A battery system is mounted to the deck of the retrofit mining haul truck. A hydrogen storage system (HSS) is installed in an engine bay volume of the retrofit mining haul truck. The engine bay was configured to contain a combustion engine (e.g., a diesel engine) prior to retrofitting the retrofit mining haul truck. At least a portion of a fuel cell system is installed in a wheel pocket of the retrofit mining haul truck. The wheel pocket was configured to contain a diesel tank prior to retrofitting the retrofit mining haul truck.

Abstract: A modular device for a spacecraft includes a propulsion system having a tank, a plenum, and a manifold, wherein the propulsion system is integrally formed with a structural frame of the spacecraft. A method of manufacturing the modular device is also discussed, the method including utilizing an additive manufacturing process to construct the propulsion system.
