For this sustainable production of hydrogen, only purified water and renewable electrical energy are needed.

We show that there are already three technically available technologies (alkaline, PEM and high-temperature electrolysis), each with specific advantages and disadvantages.

Technical solutions are therefore required to maintain the oxygen supply in regular operation as well as in the event of accidents. In particular, the role of chemicals and processes used for oxygen fixation and release are highlighted. Nature has also found fascinating ways to deal with the element oxygen and to use it in seemingly hostile places on planet Earth.
