The plasmalysis process closes the NH4 nitrogen cycle, with the advantage that no climate-damaging gases (laughing gas) are released during the plasma-based treatment of the wastewater flow and a method for generating hydrogen from pollutants is made possible.
Since this process only produces high-quality hydrogen and inert nitrogen, up to 835 kg of nitrous oxide emissions can be saved annually compared to deammonification, which corresponds to a CO2 equivalent of around 250 tons.
The green hydrogen produced can be used, for example, in mobility, electricity and heat generation or the chemical industry.
The use of energy is lower than with the electrolytic splitting of water and is largely covered by the company’s own electricity production. The hydrogen is separated from the nitrogen using a membrane process, compressed and is available for further use or sale.
The advantage of this process is that water is recovered from wastewater within the process. This improves the environmental balance of the process and reduces the utilisation of the local water supply and sewage disposal companies.
