Blue hydrogen
Power Materials
Blue hydrogen is derived from natural gas through the process of steam methane reforming (SMR). SMR mixes natural gas with very hot steam, in the presence of a catalyst, where a chemical reaction creates hydrogen and carbon monoxide. Additional water is added to the mixture converting the carbon monoxide to carbon dioxide and creating more hydrogen. The carbon dioxide emissions produced are then captured and stored leaving nearly pure hydrogen.
Blue hydrogen follows the same same process as grey hydrogen, except for the additional step where the the carbon is captured and stored.
