  • Patent number: 6864596
    Abstract: 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.

  • Patent number: 6841893
    Abstract: A method is provided for operating a hydroelectric power generating facility configured for operating in first and second operating modes. The facility includes a turbine driven power generating unit receiving a flow of water through an upstream conduit to generate electrical power. The method comprises computing a first economic value for the generated electrical power when operating in the first operating mode, and computing a second economic value for the generated electrical power when operating in the second operating mode. The method further comprises comparing the first economic value with the second economic value to identify the operating mode that provides the higher economic value, and operating the turbine facility in the identified operating mode.
