A process and apparatus for utilization of an absorption chiller for hydrogen production can include an arrangement configured for providing at least one heated waste stream of fluid from at least one hydrogen production unit to an absorption chiller generator to power the absorption chiller. Coolant can be generated via the heated waste stream for feeding coolant from the generator to an evaporator for cooling a chilling medium to a pre-selected chilling temperature to provide cooling to one or more process elements. The warmed chilling medium can be returned to the absorption chiller evaporator for subsequent cooling back to the pre-selected chilling temperature to provide a closed-circuit cooling arrangement. The waste fluid fed to the generator can be output as a cooled waste fluid for returning to hydrogen production for further use or be output for treatment and/or disposal.
