In order to create a zero emissions HYDROGEN SOCIETY, many technologies acros the energy and transport sectors are needed. Starting from the so-called "chicken and egg dilema", where not only the fuel cell vehicle but also the hydrogen refueling station infrastructure as well as the green hydrogen production via electrolysis from renewable - like solar and wind - energy is essential for maintaining a closed clean energy cycle. Similar to a symphonic orchestra, every single hydrogen technology makes its own tone, but all together they need to make nice music in order to be appreciated by the vivid audience. Hence, a concerted action is needed in order to make this happen and, last but not least, an orchestra conductor, which is virtuously accomplished by ARENA INNOVATION Germany.
