Steam methane reforming units (SMR) have been technically mastered nowadays, but most installed units are large-capacity units. In addition, the hydrogen that is produced does not reach the required purity. It would have to be purified, which increas

The pressure swing adsorption (PSA) units are widely used as an oxygen source. The storage of pressurized gaseous oxygen is limited by the capacity of a pressure vessel. The increasing share of renewable electricity sources (RES) causes intraday elec
