Clean hydrogen can be produced through several methods:
1. Electrolysis: This involves using an electric current to split water into hydrogen and oxygen. When powered by renewable energy sources like wind or solar, this method can produce truly green hydrogen.
2. Steam Methane Reforming (SMR) with Carbon Capture: Although traditional SMR is carbon-intensive, integrating carbon capture and storage (CCS) technologies can significantly reduce emissions, resulting in blue hydrogen.
3. Biomass Gasification: This process converts organic materials into hydrogen and other by-products. When sourced from sustainable biomass, this method can be considered clean.
