Verticaleas­waterturbines
voor meer energie uit waterdruk

Water2Σnergy gebruikt uiterst efficiënte versies van Darrieus. Deze zogenaamde verticaleasturbines worden veel gebruikt voor het opwekken van windenergie. Ook in vrij stromend water zijn deze turbines uitstekend toepasbaar.

De Brabantse Ontwikkelings Maatschappij ondersteunt Water2Σnergy met subsidies voor de uitvoer van Computational Fluid Dynamics-berekeningen. Deze worden uitgevoerd in Physixfactor Ltd.

In nauwe samenwerking met HERMAN REILINK Engineering Innovation, Physixfactor, de TU Eindhoven en de BOM, ontwikkelen wij een CFD testprogramma. We testen hiermee het effect van verschillende pitchhoeken van het folie en berekenen het hydrodynamische gedrag van onze turbines. Ook Helger Halewijn van Physixfactor in Nijmegen draagt in samenwerking met Water2Σnergy onderzoekswerk bij.

Tidal Energy Technology for ultra low head tidal energy


Researcher Jacob van Berkel of Entry Technology discusses ultra low head tidal energy. 


What is the relevance of advancing technology for ultra low head tidal energy? 


“This technology has a huge export potential, in particular for applications in estuaries outside of the Netherlands. The Netherlands can serve as testing ground for developing and nurturing the technology. This kind of renewable energy harnesses water head and velocity, and is also compatible with rivers making use of a dam. In the Dutch Rhine Scheldt estuaries the water head does not usually exceed about one meter. Still it is certainly possible to generate power. For example, the Brouwersdam (one of the Dutch storm surge barriers) is likely to be re-opened for tidal flows. Though initially this reopening is intended to improve hinterland water quality, it is also offers potential for applying the technology to harness tidal energy.” 


Are there any bottlenecks?


“The initial investment needed for such installations is typically high. To make it worthwhile and obtain a high power yield, a large number of turbines would be required. However, as fish are known to collide with the turbines placed in their stream, the authorities have imposed guidelines that allow no more than 0.1% fish mortality per passageway. 


And how can these be resolved?


“As of 2013 the EU-project Pro-Tide has seen a number of international parties working on developing the right technique. The project is led by the Dutch province of Zeeland. Within this project, only the Dutch partners have a focus on ultra low head tidal energy. It has been tested and proven that the new, more affordable technology allows the conversion of river and tidal energy into electrical power. Fish have a survival rate of 99% to 100% in passing a turbine. We would like to see this technology applied in the Brouwersdam.”
