摘要： Leveraging a turboexpander to provide additional functionality in compressed gas fueled systems is disclosed. The system includes a compressed gas storage device storing a compressed gas at a first pressure. A turboexpander operably coupled with the compressed gas storage device, the turboexpander comprising a turbine coupled with a drive shaft, the turboexpander to maintain the compressed gas below a threshold temperature limit as it controllably expands the compressed gas from the first pressure to the second pressure via an amount of work obtained from a rotation of the turbine and the drive shaft. A compressed gas receiving device to receive the compressed gas at the second pressure from the turboexpander and generate an amount of electrical energy from the compressed gas.

摘要： Method and system for managing hydrogen fuel in hydrogen fuel cell-powered aircraft is disclosed. The method identifies unused hydrogen fuel in a fuel tank of the aircraft. Determines an amount of the unused hydrogen fuel in the fuel tank of the aircraft. Transfers the amount of the unused hydrogen fuel from the fuel tank of the aircraft into a hydrogen fuel cell of the aircraft and converts the amount of the unused hydrogen fuel into electricity via the hydrogen fuel cell of the aircraft.
