It is the process of capturing and storing carbon dioxide (CO2) before it is released into the atmosphere.
When Hydrogen is produced through the steam reforming process but the carbon generated is captured and stored, it is known as Blue Hydrogen. It is to be noted that the process is endothermic, i.e., heat must be supplied for the initiation of the reaction. High-temperature steam ranging between 700☌–1,000☌ is used to produce hydrogen from a methane source, such as natural gas. It is the process through which hydrogen is generated from natural gas. It is the most common form of Hydrogen and is produced using fossil fuels through a process called Steam Methane Reforming.
