Title : A test stand for water treatment systems and green hydrogen production units: Description and preliminary research
Abstract:
The transition from a hydrocarbon-based economy to renewable energy sources poses new challenges. Although renewable energy sources are environmentally friendly solutions, their operation is characterised by unpredictability and discontinuity of energy generation. One way to mitigate this problem at the level of an average household may be to use a low-power hydrogen production installation for heating, energy storage, or electricity generation. A test stand has been developed for testing such low-power installations. These installations consist of a water treatment system for electrolysis and a green hydrogen production unit with a maximum power consumption of 7 kW. The test stand enables the measurement of water parameters at the inlet to the system and after the multi-stage filtration. The measuring system monitors the water supplied to the electrolysis device and its consumption during this process. Among other things, it checks the required level, pressure, and conductivity of water with an accuracy of 0.04 μS/cm. The test stand measures the operating parameters of the hydrogen generation unit at its inlet and outlet. It has been designed to verify installations supplied with rainwater or mains water and to test one or more electrolysis modules simultaneously. The test stand can be used to verify water treatment systems for the electrolysis process and to verify individual modules or sets of hydrogen electrolysers at the design, prototyping, or full-scale production stages.
