Increasing the reliability of water systems for hydrogen processes
The hydrogen industry is growing rapidly worldwide. Electrolysis processes, new plant concepts, and industrial ramp-up place high demands on process stability, efficiency, and operational reliability. At the same time, water-based systems must be scalable – both at the water supply stage and on the wastewater side. The production of high-purity water, stable circuits, and the responsible disposal of concentrated wastewater – including zero liquid discharge (ZLD) processing – are crucial prerequisites for a reliable end-to-end process. At the same time, water quality and controlled heat transfer influence the feasibility and efficiency of electrolysis processes. In operational practice, fouling and scaling are key issues in the water circuits. This is precisely where Taprogge’s expertise comes in. Our solutions support the reliable operation of water-carrying systems in hydrogen production. They help to ensure that circuits are operated in a controlled manner and that new technologies are used efficiently in day-to-day operations. The specific requirements of electrolysis, cooling, and supply processes highlight which applications are particularly relevant in the hydrogen industry.
Water for hydrogen: a profitable business case?
Sample calculation
Roughly 9 kg of high-purity water are required in order to produce around 1 kg of hydrogen. Water is therefore a key resource in hydrogen production alongside electrical energy. This raises the following key questions:
- Which water sources should or may be used?
- Which chemical additives are required for treating the water, and can they be discharged into the sea in offshore applications?
- What concentrated wastewater streams (brine) are produced in onshore electrolysis, and who is responsible for treating them?
