Sub-Product

BLUE HYDROGEN is Hydrogen:

• produced from Fossil Fuels (e.g. Grey, Black, or Brown Hydrogen)
• where CO₂ is captured and either stored of repurposed.

• Processing 1 kg of Natural Gas to produce 0.5 kg of Hydrogen.
• Associated CO₂ generated by Reformer/Shift Reactions is 5.5 kg per kg H₂.
• Additional CO₂ from burning Fuel in Reformer Furnace brings total to a range from 9 -11 kg CO₂ per kg H₂ depending on Process efficiency.
• Total of three Carbon Capture (CC) Stations shown.
• Pressure Swing Adsorption (PSA) Unit separates the pure Hydrogen product from the Tail Gas, which is recycled in the Reformer Furnace.
