Abstract
The present invention provides a process for dispensing gaseous hydrogen, comprising the steps of: a) providing a first vessel comprising a first quantity of gaseous hydrogen at a pressure in the range of from 350 to 1000 bar absolute and a temperature in the range of from −20° C. to 50° C.; b) passing in the range of from 40 to 100 wt %, based on the weight of the first quantity, of the first quantity gaseous hydrogen from the first vessel through an isenthalpic valve to obtain a cold second quantity of gaseous hydrogen having a temperature in the range of from −100 to −20° C.; and c) dispensing the cold second quantity of gaseous hydrogen to a second vessel. In a further aspect the invention provides a system for dispensing gaseous hydrogen.
