The Shell Blue Hydrogen Process

Proven technologies and real-world experience

Although green hydrogen (from the electrolysis of water using renewable power) is likely to be a long-term solution, analysts suggest it may not achieve cost parity with blue hydrogen, which is produced from natural gas with applied carbon capture and storage (CCS) technologies, until about 2045.

The Shell Blue Hydrogen Process integrates proven technologies – Shell gas partial oxidation (SGP) and ADIP ULTRA.

SGP technology is an oxygen-based system with direct firing in a refractory-lined reactor. It requires little or no feed-gas pretreatment, is a non-catalytic process that produces high-pressure steam from waste heat rather than consuming it and has no direct carbon dioxide (CO2) emissions. SGP has more than 30 active gas and residue gasification licensees, and there are more than 100 SGP gasifiers worldwide, including at the Pearl gas-to-liquids plant in Qatar, and Pernis refinery in the Netherlands.

ADIP ULTRA is a proven solvent technology for capturing CO2 from high-pressure process streams.

Advantages over steam methane reforming (SMR) and autothermal reforming (ATR)

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 carbon-capture efficiency and simplifying the process line-up, which offsets the oxygen production costs.

And, compared with ATR, it has a simpler line-up, with no need for substantial feed gas pretreatment, and does not require a fired heater that emits CO2. Another advantage is that the Shell Blue Hydrogen Process generates, rather than consumes, steam to satisfy the demands of the process.

These benefits translate to 22% lower levellised cost of hydrogen for SGP technology compared with ATR, and even greater benefits when compared with SMR.

Shell also has CCS experience through its involvement in multiple projects in different phases of development and can offer key experience and insights into CO2 capture, compression, transport and storage.
