Blue hydrogen is a low-carbon alternative to grey hydrogen, but it still has some drawbacks, such as higher costs and reliance on fossil fuels. Therefore, blue hydrogen should be used as a transitional solution until green hydrogen becomes more widely available and affordable.
What is Gray Hydrogen?
The gray hydrogen process is an endothermic (absorbs heat) reaction in three stages. The first stage involves heating liquids to high temperatures (around 1292 to 1832 F or 700 to 1,000 C) to produce steam. Next, methane (CH4) reacts with the steam to produce hydrogen, carbon monoxide, and carbon dioxide. A nickel catalyst can make …

Blue hydrogen is when natural gas is split into hydrogen and CO2 either by Steam Methane Reforming (SMR) or Auto Thermal Reforming (ATR), but the CO2 is captured and then stored. As the greenhouse gasses are captured, this mitigates the environmental impacts on the planet. The ''capturing'' is done through a process called Carbon Capture ...
