Technology

UNIWASTEC’s evaporation electrolysis process is the world’s only technology for the direct extraction of green hydrogen from wastewater or seawater.

The enrichment of the high-purity hydrogen takes place in a special process in which the process water repeatedly passes through the process of evaporation and thawing one after the other and finally separates as clean condensate.

By repeatedly passing through the process, hydrogen successively accumulates in the material flow in certain phases and can be produced there in a specially designed electrolysis with low electrical energy input.

In this way, an overall efficiency is achieved for the production of high-purity hydrogen that far exceeds all other electrolysers available on the market.

Core Advantages

Extremely low-maintenance

No chemicals or filters are needed. Extremely low-maintenance system.

Resource-saving

No waste of drinking water. Hydrogen is obtained from wastewater or seawater.

More than 84% efficiency

Market-leading efficiency from waste water to high-purity hydrogen an overall efficiency of more than 84%. From 1 ton of wastewater we produce 90 tons of green hydrogen and 711 tons of green oxygen.

Low power consumption: 39 MWh for 1 t of wastewater including water purification.  

Flexibility & Quality

The electrolyser is modularly scalable and can thus be adapted to the respective demand.

The hydrogen and oxygen are of the highest purity 99.999%.
