Hydrogen and oxygen research at Zwolle’s Hessenpoort wastewater treatment plant

In Zwolle’s Hessenpoort wastewater treatment plant (WWTP), the Drents Overijsselse Delta Water Board (WDODelta) is funding cutting-edge, novel studies of hydrogen and oxygen.

With this solution in place, a business park can become energy independent while also relieving the local power grid.

Recently, WDODelta undertook research into an alternative method of purifying waste water in conjunction with STOWA, the knowledge center for regional water management. Instead of the costly and inefficient aeration from the outside air, pure oxygen was injected into the aeration street, the beating heart of the sewage treatment facility.

In order to install an electrolyser, the water board has begun a new step that involves modifying the sewage treatment system. To produce hydrogen, heat, and oxygen from water, a device called an electrolyser employs electricity.

Large-scale energy generation and consumption take place in close proximity to one another, forming the Smart Energy Hub. The Drents Overijsselse Delta Water Board and H2-GO BV have worked closely together on this study at the Hessenpoort business park.
