Landmarc Scientific Concepts: Blue Hydrogen
What is the mysterious sounding Blue Hydrogen?
Blue hydrogen is hydrogen produced from natural gas through a process called steam methane reforming (SMR), where natural gas reacts with steam to produce hydrogen and carbon dioxide. The CO2 generated is captured and stored underground, a process known as carbon capture and storage (CCS), to reduce greenhouse gas emissions. Blue hydrogen serves as a transitional energy source, offering lower carbon emissions compared to grey hydrogen, which doesn’t use CCS. It is seen as a bridge towards green hydrogen, which is produced from renewable sources via electrolysis, emitting no CO2. Blue hydrogen helps in decarbonizing industries reliant on hydrogen.
There has been some debate whether Blue Hydorgen should replace Natural Gas. Proponents harp on the fact that there is no untraced and uncontained carbon emissions in the process while opponents maintain that it is plainly inefficient in terms of the energy cycle and thus a net waste of natural and limited resources.
