HYDROKINETIC POWER DEFINITIONS There are two types of hydrokinetic power, current-based and wave-based. Each is described below. CURRENT-BASED HYDROKINETIC POWER Currents in hydrokinetic canals use a variety of technologies to generate zero-emissions, renewable energy from water currents. These currents typically occur at a variety of application points: • River currents (river power known as in-stream, free-flow, open river or run-of-river projects); Energy is generated from the water currents by a variety of technologies, including: • Horizontal axis turbines (with no ducts, single ducts and dual ducts); As the water current passes through the turbine (rotor fan), the turbine will rotate on a shaft that is connected to the generator. WAVE-BASED HYDROKINETIC POWER Wave-based hydrokinetic power also uses a variety of technologies to generate zero-emissions, renewable power from wave action. Energy is generated in a variety of ways depending on the technology. Wave buoys generate electricity by riding on the motion of the wave crest and wave trough. This up and down motion can drive water pumps, solenoids, hydraulic systems and electric generators.
