Blue Hydrogen

Blue hydrogen refers to hydrogen that is produced from natural gas through a process called steam methane reforming (SMR), combined with carbon capture and storage (CCS). In this method, natural gas is converted into hydrogen and carbon dioxide. The carbon dioxide generated during this process is captured and stored underground, preventing it from entering the atmosphere. This makes blue hydrogen a lower-carbon alternative compared to traditional grey hydrogen, which is produced from natural gas without capturing the emitted carbon dioxide. Blue hydrogen is considered a transitional energy source that can help reduce greenhouse gas emissions while supporting the shift towards a more sustainable and renewable energy system.
