A gas displacement assembly includes a storage container, a pump that pumps a pressurized gas material into the storage container, a cooling chamber that houses a coolant and cools the gas material to a cryogenic temperature, and a coolant line that transports coolant through the cooling chamber to cool the gas material.

A hydrogen storage tank of a vehicle includes a housing defining an inlet/outlet opening, a control assembly extending into the housing through the opening and comprising a plurality of sensors, and a controller configured to receive signals from the plurality of sensors. The controller of the hydrogen storage tank is configured to, in response to a request for a handshake signal, initiate sending the handshake signal, and in response to the vehicle being started, initiate periodically sending data indicating parameter values received from the plurality of sensors.
