The Shell Coal Gasification Process (SCGP) uses an upflow, entrained flow gasifier operating on a dry feed at slagging temperatures (Fig. ). The upflow arrangement allows separation of syngas and slag largely within the reactor itself. Typically there are four sidemounted burners located in the lower part of the reactor.

The Shell Blue Hydrogen Process offers significant advantages over alternative technologies, which include steam methane reforming (SMR) and autothermal reforming (ATR). For example, compared with SMR, it saves money by maximising carboncapture efficiency and simplifying the process lineup, which offsets the oxygen production costs.
