New Dutch Sustainable Water technology for Colombia

On a small palm tree island, Johnny Cay, in the Caribbean a new Dutch technology to produce with one windmill both water and electricity will be installed.
This Colombian island close to the Colombian tourist island San Andrs receives 350.000 day tourist per year but water has to be transported to the island in bottles and for the restaurants ice blocks have to be brought daily to cool the fish, because there is no fresh water or electricity.
It is a small nature reserve and it was the wish of Coralina, who is responsible for the island, to produce water and electricity fully sustainable.

SolteQ’s Fresh Water Mill

SolteQ Energy developed a new type windmill, which converts the wind energy into high pressure and this high pressure is used to drive a desalination unit (reverse osmosis) to produce fresh water. Wind energy is not constant and the excess energy will be used to produce electricity as well.
The new concept will first be installed in Leeuwarden early next year on a special area reserved for innovative water and energy technologies.
A group of organisations will deliver these systems: Lenntech, specialist in water technology, Hydroton, specialist in hydraulic solutions, Hoekstra-Suwald specialist in rebuilding and installing windmills and Solteq Energy specialist in renewables. The Technical University of Delft, civil engineering, water technology, supports the group with their experience of 5 years of study on combinations wind and solar produced water.
The Netherlands Enterprise Agency (RvO) is financing the Johnny Cay project on the condition that the project will be the heart of an educational system to promote and support Dutch sustainable solutions to Colombia and surrounding.
We expect that export from the Netherlands deriving from this pilot project will be within two years well in excess of the five-fold amount of the financial support of RvO. Yearly in this area alone is a capacity installed of about 60.000 m3/day. This is 6.000 times the capacity of the pilot installation in Johnny Cay.
In the whole world 60% of the drinking water is produced by reverse osmosis and the majority of those installations is using expensive fossil produced electricity. The concept developed by Solteq Energy is not only fully sustainable but will cut the production cost in areas with sufficient wind by almost half. 
And the combined water and electricity production allows areas with no utility grid to get access to fresh water and electricity.

Solteq to build wind-RO desalination plant on Johnny Cay island, Colombia

Solteq Energy announced that it will build a new type of wind mill on the Colombian tourist island of Johnny Cay for the supply of both  energy and fresh water.

The energy of the wind mill will be converted into high pressure to  drive a reverse osmosis water installation for the desalination of sea  water.

Johnny Cay is a small island situated close to the Colombian tourist  island San Andr©s, receiving 350.000 day tourist per year. Water has to  be transported to the island in bottles and for the restaurants ice  blocks have to be brought daily to cool the fish, because there is no  fresh water or electricity.

Fully sustainable energy and water supply
It is  the wish of the local authority Corporación para el Desarrollo  Sostenible del Archipi©lago de San Andr©s (Coralina), to produce water  and electricity fully sustainable.

Solteq Energy developed a new type windmill, which converts the wind energy  into high pressure and this high pressure is used to drive a  desalination unit (reverse osmosis) to produce fresh water.

Wind energy is not constant and the excess energy will be used to produce electricity as well.

No utiltity grid
Worldwide 60% of the drinking  water is produced by reverse osmosis and the majority of those  installations is using expensive fossil produced electricity.

The combined water and electricity production does not require a utility grid.

The concept developed by Solteq Energy is not only fully sustainable  but in areas with sufficient wind the water production costs will be cut by almost one half.

Dutch demo site
The new concept will first be  installed in Leeuwarden, the Netherlands, early next year on a special  research area, reserved for innovative water and energy technologies.

A group of companies and research organisations will be involved,  including Lenntech, specialist in water technology, Hydroton, specialist in hydraulic solutions, Hoekstra-Suwald specialist in rebuilding and  installing windmills and Solteq Energy specialist in renewables.

The Delft University of Technology supports the group with their  experience of five years of study on combinations wind and solar  produced water.

Another supporter of the project is the Netherlands Enterprise Agency (RvO) that considers it a show case for Dutch sustainable solutions to  Colombia and Caribbean region.
