The development of an effective hydrogen production system using energy from renewable energy sources (RES) becomes the goal of the consortium established by the AGH University of Science and Technology in Krakow, the Institute of Energy and Grupa LOTOS SA. As part of it, the engineers will try to make the production of this energy carrier more ecological.  

So-called green, or zero-emission hydrogen, can be obtained by electrolysis of water and thus separation of H2O under the influence of an external electric voltage. This method is almost 100% ecological, provided that the electricity used origins from renewable sources, i.e. energy from the sun, wind or water.

None of the currently available electrolysis methods, i.e. in an alkaline solution, using low-temperature electrolysers with polymer membranes, or finally the one carried out in high-temperature electrolysers, are so popular or widely used today. These methods are more expensive and less effective compared, for example, to steam power of natural gas. However, the scientists are working on to make the electrolysis process more efficient, stable and cheaper.
