エリス Company Profile

The load-following open micro-hydropower generation WaterWeco(R) can contribute to the environment with low head (over 1.0m) and low flow (over 1.0cms).

Output corresponds to approximately 5 to 20 kW per unit. Output can be enhanced by installing multiple units. Brief history: From 2009, collaborated with municipalities such as Okayama City, Tsuyama City in Okayama Prefecture, and Miyoshi 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 improvements in power generation efficiency, with support from organizations such as the Okayama Prefectural Industrial Promotion Foundation, and collaborating with Nagasaki University Graduate School of Engineering and Nishinihon Fluid Technology Co., Ltd., a fluid research institution, from 2016 for joint research, CFD fluid analysis, model testing, optimization, product development, and completion of actual machine installation operations, with domestic patent registration in October 2020 (along with approximately 60 overseas patent registrations, WaterWeco® trademark, and design registration for turbine blade shapes). *Effective installation is possible in suitable locations that were previously deemed unfeasible due to overflow risks (low drop height drop structures). ★ Labor-saving: Easy measures against dust and heavy snowfall (no dust removal equipment required): Significant reduction in maintenance costs (initial costs). ★ Automatic layout control mechanism that adjusts to flow rate fluctuations ➢ Stable power generation efficiency during the period. ★ Consideration for biodiversity: Fish passages can be secured even when installed in rivers where fish migrate. ★ Awards and technology registration history: Received various awards including the Eco-Products Award and the Chairman's Award from the Invention Association; registered with UNIDO STePP.
