Review on the research of hydrogen storage system fast refueling
Firstly, the kinetic energy of the fast-flowing hydrogen converted into the internal energy gas generates lots of heat in the process of filling. Secondly, the compression of hydrogen in the tank during its filling causes a temperature rise, which is the most important among all factors leading to temperature rise.

Internal energy when filling an evacuated tank
No, the internal energy of a gas is not constant when filling an evacuated tank. As the gas is compressed and transferred into the tank, its internal energy increases due to the work being done on it. However, if the tank is insulated and no heat is exchanged with the surroundings, the internal energy of the gas will remain constant.
