Humanity needs clean drinking water to be able to survive but only 0,5% of all water on earth is drinkable. Our patentend technology cleans water from micro pollutants and turns it into 99,9% clean water. Enabling wastewater treatment to become more efficient and supporting the industry to develop their own clean water loop. >>

For our proces we need oxygen, which we can separate from water, resulting in O2 for our proces and H2 for other uses. Our technology is so versatile that we foresee a relatively fast installed network of H2 producing places. Each next installation will be more efficient and cost effective and will reduce the need for nationwide infrastructure projects. >>

By using excess green energy we can produce additional H2 and store it for later use. This will reduce the need for net-controllers to ‘curtail’ the production of windmill- and solar parks and make those existing green energy initiatives much more efficient.>>


Purifying up to 99,9%
Removing the final 'hurdles'
No (additional) residues

No dumping in rivers or surface waters
Tailor-made clean circular water loop
Purifying up to 99,9%
No (additional) residues
No additional pollution
For green municipalities


H2 on demand
H2 station for transport & logistics
Accelerating the energy transition
Excess H2 can be used as first source of energy for industrial processes
H2 stations for the own logistics fleet
H2 is an excellent source of energy
Storage station for local distribution
Municipalities, neigtbourhoods a.o. can all create their own clean water loop and make local H2 stations for their cars.


Currently all windmill and solar parks are only operating at a 7 - 10% efficiency because our net can't take the additionale burden.
We have the solution!
By simply connecting our local energy storage to local energy providers we provide a huge H2 batter. For use when there is no sun or wind!
Our H2 battery obviously can be used as a tank station.
For local transportation companies but also for consumers enabling a fast uptake of the fuel cell cars which are more sustainable than electric cars nowadays.


Water Boards are still unable to remove many micro pollutants known to be bad for our health. Lack of clean water is an increasing global problem, rapidly resulting in a humanitarian crisis and with tons of plastic bottles ending up in the environment. We want and need to put a stop to this!
A successful energy transition will largely rely on H2. For some reason we start building huge static factories and choose to forget the required investments in infrastructure. We provide a local and regional solution, cheaper, faster, more efficient and for sure with less pipelines.

In so many countries there is no drinkable water other than bottled. Worldwide we use 1 million bottles every minute! Alone in The Netherlands we use 930 million bottles a year and when you imagine it takes nature 450 years to digest a bottle ...
