Namibian lodge tests green hydrogen technology to convert wastewater into clean energy and water

The HygO project is a containerized system that treats wastewater to produce clean water and generates renewable energy through green hydrogen. This initiative, funded by Germany’s Federal Ministry for the Environment, Climate Action, Nature Conservation and Nuclear Safety, aims to address water scarcity and energy needs in arid environments like Namibia. The system processes all wastewater from the lodge and employee accommodation, using biological and mechanical methods to produce cleaner water.

This treated water then undergoes electrolysis, powered by solar panels, to split into hydrogen and oxygen. The hydrogen is stored for electricity generation, while the oxygen is recycled back into the wastewater treatment process to further purify the water. Gondwana Collection Namibia, the lodge's operator, partnered with the consortium due to its commitment to sustainability and the region's challenging conditions.

The pilot system, with a capacity of approximately 15 kilowatts, currently supports employee accommodation, with plans to assess its performance and potential for wider applications. The project is designed with rigorous safety standards, adhering to European certifications and featuring remote monitoring. This three-year program seeks to demonstrate how wastewater can be a valuable resource, potentially prov
