A turbine installation configured for large scale hydrogen production includes a foundation structure separating an upper elevation headwater from a lower elevation tailwater. The foundation structure defines a water passageway extending therethrough between an inlet adjacent the headwater and an outlet adjacent the tailwater. A runner is supported for rotation by the foundation and disposed in the water passageway intermediate the inlet and the outlet so that water flowing through the passageway as a result of head differential causes rotation of the runner. A generator is supported by the foundation and connected to the runner by a rotary shaft for generating electrical power as the runner rotates. An electrolyzer is electrically coupled to the generator for receiving the electrical power and producing hydrogen. A control system is capable of sensing the remaining hydrogen storage capacity and performing an economic comparison analysis to determine whether operating the turbine to produce additional hydrogen or to supply a utility grid with power provides the highest economic return.
