Webcapacity. Thus, distributed production via smaller reformer systems is viewed as an attractive near- to mid-term option for supplying hydrogen, particularly for vehicles and in regions where low-cost natural gas is readily available, and for securing market share for hydrogen technologies. Reformer technology is commercially available today. Autothermal reforming (ATR) uses oxygen and carbon dioxide or steam in a reaction with methane to form syngas. The reaction takes place in a single chamber where the methane is partially oxidized. The reaction is exothermic. When the ATR uses carbon dioxide, the H2:CO ratio produced is 1:1; when the ATR uses steam, the H2:CO ratio produced is 2.5:1. The outlet temperature of the syngas is between 950–1100 °C and outlet pressure can be as high as 100 bar.
