The current trend in the energy sector is focused on finding solutions for greening the energy economy. Hydrogen offers an opportunity to achieve this goal. One of the key activities for hydrogen industry development is to conduct basic and developmental research and development in the field of hydrogen production and use, which solve technical problems. The production of hydrogen is still a major challenge, due to the high costs and often also environmental burdens it generates. It is possible to produce hydrogen in a completely emission-free way: using a process of electrolysis powered by renewable energy. Hydrogen produced using renewable energy is sustainable in the long term, enabling, among other things, the expansion of energy use, storage and transport. The paper presents the concept of a research stand for the storage of renewable energy in the form of hydrogen chemical energy with the measurement methodology. The experimental stand includes a photovoltaic array for energy generation coupled with electricity storage and a hydrogen generation facility. The research involves the use of proton exchange membrane electrolysis (PEM) technology, which is characterized by high efficiency and flexibility of energy extraction for the process of electrolysis from renewable sources. The aim of this study is to assess local solar conditions in terms of hydrogen production as a clean fuel.
