Energy is one of the most important parts of our life. To use it in an environmentally friendly way, electricity from renewable sources is becoming increasingly important. The focus is particularly on solar energy. However, since solar energy is only available for about 1000 hours a year in many regions, we urgently need ecologically sound storage facilities to maintain security of supply. The local production of green hydrogen from solar power using Fronius Solhub is a pioneering solution. It enables the production and storage of hydrogen anywhere on site and its reconversion.
