What are the Main Methods for Hydrogen Production?
Several methods exist for producing hydrogen, with the most prominent ones being:
1. Steam Methane Reforming (SMR) - This process involves *reacting methane* with steam in the presence of a catalyst, typically nickel-based, to produce hydrogen, carbon monoxide, and a small amount of carbon dioxide. 2. Electrolysis - In this method, electrically conductive catalysts like platinum or iridium are used to split water into hydrogen and oxygen using an electric current. 3. Partial Oxidation (POX) - Hydrocarbons such as methane are partially oxidized using a catalyst to generate hydrogen, carbon monoxide, and water. 4. Biomass Gasification - Biomass is converted into hydrogen-rich syngas through catalytic gasification, often utilizing catalysts like nickel or iron to enhance the process.
