Micro Hydropower Generation System WaterWeco®
Micro Hydropower Generation System WaterWeco®
WaterWeco® Micro hydro power generation that generates electricity even in low head and low flow environments that have never existed before.
WaterWeco® enables stable power generation with minimal fluctuations throughout day and night, thanks to its unique patented mechanism. It is an initiative to effectively utilize natural energy by installing water wheels in small rivers and waterways scattered across various regions. Through repeated demonstration experiments with numerous municipalities, universities, and research institutions, it has been improved to generate electricity efficiently even at low head heights. The system primarily handles scales of several tens of kW. (Note: Power generation can be increased through parallel installation.) 【Features】 ■ Stable power generation with minimal fluctuations throughout day and night (due to unique mechanism) ■ Equipment utilization rate 5 to 8 times higher than solar power generation ■ Can be commercialized at a higher selling price than solar power generation when utilizing FIT ■ Approximately 170,000 kW of potential in agricultural waterways (within Japan) ■ Lower environmental impact compared to large-scale hydroelectric power generation ■ Easy debris management (due to unique mechanism) ■ Maximizes flow velocity with an extremely low risk of overflow (due to unique mechanism) ■ High power generation efficiency (due to unique turbine) ■ Ensures fish passage and considers biodiversity (due to unique mechanism) *For more details, please feel free to contact us.

Detailed information
-
Mini hydroelectric power generation, a sustainable distributed energy source suitable for the natural environment. Small-scale hydroelectric power generation under low-flow and low-drop conditions.
Company information
The output mainly supports a range of 5 to 100 kW. Due to unitization, parallel installation is possible. (Note: Strength calculations may be necessary depending on the flow rate.) Brief history: From 2009, collaborated with municipalities such as Okayama City, Tsuyama City in Okayama Prefecture, and Miri City in Hiroshima Prefecture, as well as consulting companies for feasibility studies (demonstration experiments), owning power generation and self-consumption facilities, conducting long-term operational tests, and improving power generation efficiency, with support from the Okayama Prefectural Industrial Promotion Foundation and Nagasaki University Graduate School of Engineering, a fluid research institution, and Nishinihon Fluid Technology Co., Ltd. for collaborative research, optimization, product development, and completion of actual machine installation operations. Patents were registered in October 2020 (including other overseas patents in Europe and the United States, the WaterWeco® trademark, and design registration for the water turbine blade shape). *Installation is possible in suitable locations where installation was previously impossible due to overflow risks. ★ Labor-saving ➣ Easy measures against debris and heavy snowfall (no dust removal device required) ➢ Significant reduction in maintenance costs (initial costs). ★ Automatic layout control mechanism adjusted to flow rate fluctuations ➢ Stable power generation efficiency during the period. ★ Consideration for biodiversity ➣ Even when installed in rivers where fish migrate, fish passages can be secured. ★ Awards and technology registration history: Various awards including the Eco-Products Award and the Chairman's Award from the Invention Association, and registration with UNIDO STePP.
