Kinetic Hydropower System (KHPS)
Verdant Power’s Kinetic Hydropower System (KHPS) is a water-to-wire system utilizing horizontal-axis turbines that convert the kinetic energy of fast-moving (> 1 m/s) water currents into clean renewable electricity. The KHPS can be placed in tidal, river and channel resources and is installed fully under water, invisible from shore, and does not require dams or impoundments.
The KHPS was designed with an imperative for simplicity and scalability to minimize O&M costs and maximize applicability. Turbines can be scaled to a range of sizes and arrayed in various configurations, allowing for power provision ranging from distributed generation in urban and village settings to base power generation at more remote deepwater locales.
The central component of the KHPS is a horizontal-axis turbine equipped with an open three-bladed rotor. The turbines are installed fully under water, invisible from shore and are designed to self-rotate into the prevailing current (like a weathervane) so that the blades are optimally aligned to generate energy. In tidal settings the turbines passively yaw (turn ~170 degrees) to generate power from both the ebb and flood tidal flows.
The rotating motion of the blades drives an induction generator, located within the main body of the turbine, to generate electricity, which is transferred to onshore equipment via an underwater cable. The blades rotate at a slow and steady rate of approximately 40 RPM, well below normal water vessel propeller speeds.
Gen5 KHPS Advancement
Verdant Power has advanced the KHPS to the 5th Generation (Gen5) based on operating experience from the Gen4 system demonstrated at the Roosevelt Island Tidal Energy (RITE) Project. While the Gen4 system proved excellent performance in converting the energy in the tidal currents into grid-connected power, the Gen5 KHPS is a design advancement aimed at high reliability, longevity and cost-effective commercial manufacturing. The Gen5 turbine features a custom integrated drivetrain with substantially fewer parts, and improved sealing over preceding generations. More >>
