HYLOW - Hydropower converters with very low head differences

Description: Das Projekt "HYLOW - Hydropower converters with very low head differences" wird vom Umweltbundesamt gefördert und von Technische Universität Darmstadt, Institut für Wasserbau und Wasserwirtschaft, Fachgebiet Wasserbau und Hydraulik durchgeführt. Small hydropower with very low head or pressure differences below 2.5 m and hydraulic power ratings of 50 to 1000 kW is a significant renewable resource, with an estimated unused potential in rivers alone of e.g. 600 to 1000 MW in the UK and more than 500 MW in Germany. The economically and ecologically efficient utilisation of this hydropower bracket still constitutes an unsolved problem since conventional turbines (Kaplan or Cross flow) are not cost effective, and since they are considered to have a negative ecological impact. In order to open up this hydropower bracket for exploitation, an innovative solution - the hydrostatic pressure turbine - was developed. This novel hydraulic machine utilises differential hydrostatic pressures; with theory and initial model tests indicating high theoretical efficiencies for low head differences. It rotates at slow speeds and operates under atmospheric pressure with a continuous bed, thus minimising negative impact on fish. Prime Contractor: University Southampton; Southampton; UK.
