Unlocking the energy of rivers for everyone

Unlike the traditional turbine-based solution, SPEARhydro harnesses the river energy by using an internationally patented pendulum movement of fins located beneath a waterway- capable vessel. The slow-moving, durable fins propelled by a river stream are connected to standard generators that produce electricity. Unlike common propellers and turbines, fins don’t clog, can withstand debris, and are safe for wildlife. These unique characteristics allow long-term deployment in free flow environments that was not possible until now.

The anchored power plant can be plugged into a local grid network or can be used as an off-grid or hybrid solution for own electricity demand. SPEARhydro's modular technology offers versatility for urban areas with high energy demand.

With a certified nominal power of 15kW/unit at 2m/s river flow, it can be customized and scaled up for various applications. Our technology is embedded in a transportable, plug & play device that doesn’t require large supporting infrastructure and can be deployed on any navigable river. With a targeted capacity factor higher than 80%, SPEARhydro strives for maximum efficiency.
