DuoTurbo

Providing Industrial and Competitive Family of Low-CAPEX Integrated Plug-and-Play Energy Recovery Stations

The project focuses on turning a counter rotating micro-turbine proof of concept into a range of standard energy recovery stations able to harvest energy on drinking water networks. The plug-and-play concept to be developed will require a low investment for the final customers, reaching economic feasibility with an available hydraulic power below 25 kW. A new part of the Swiss and international renewable energy potential will then be targeted and profitably exploited.

EPFL LMH activities is focused on the modeling of the electro-mechanical system behavior and performance in order to develop a dedicated sensor-less control strategy adapted to double-regulated turbines such as the DuoTurbo concept turbine with counter-rotating runners to be controlled with a minimal set of external sensors.
