Blue Hydrogen

Blue hydrogen is produced from natural gas in the same way as gray hydrogen. The key difference is that it is supported by carbon capture and storage (CCS). When carbon dioxide capture is added within the steam methane reforming (SMR) or autothermal reformation (ATR) process, the hydrogen produced can be classified as “blue”.

The carbon dioxide is captured, compressed and stored either permanently or for further use for other applications (termed carbon capture, utilisation and storage or CCUS).

Amine-based carbon capture

One method of carbon dioxide capture or removal is through absorption with solvent-based solutions (or amines). Amine-based carbon capture is placed before the pressure swing adsorption stage in SMR or ATR as, during this stage, the adsorption material is irreversibly poisoned by hydrogen sulphide.


After the sour gases are absorbed, the “rich” amine is then regenerated through a desorber that strips the carbon dioxide before the “lean” amine is looped back to the absorber. This carbon dioxide is compressed before storage.
