Abstract
The hydrogen compressing system has a first unit that receives hydrogen at low temperature and low pressure and compresses it, a second unit that cools down the hydrogen received from the first unit and a third unit that heats up and pressurizes the hydrogen received from the second unit; the high-pressure hydrogen is stored in a tank and afterwards may be supplied, for example, to a tank of a vehicle; pressurization at the third unit () is achieved by introducing cold hydrogen gas, well below ambient temperature, received from the second unit into the tank and heating it while the tank is closed preferably till when the hydrogen inside the tank reaches ambient temperature; heating-based compression allows to easily obtain high pressure through a relatively simple system and without risk of reducing the purity of the hydrogen.
