The difference between green hydrogen and blue hydrogen

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 ...
