Hydrogen generation

Hydrogen generation is also known as hydrogen production which lies at the heart of the hydrogen infrastructure, serving as the foundation for the widespread use of hydrogen as a clean energy source. There are various methods of hydrogen generation, with two prominent approaches being electrolysis and steam methane reforming. Electrolysis involves the use of electricity to split water into hydrogen and oxygen, producing what is known as green hydrogen when powered by renewable energy sources. This method offers a sustainable and emissions-free way to produce hydrogen, contributing to a carbon-neutral energy system. On the other hand, steam methane reforming involves the reaction of methane (typically derived from natural gas) with steam to produce hydrogen, resulting in grey hydrogen. While this method is widely used due to its cost-effectiveness, it generates carbon dioxide emissions. However, with carbon capture and storage (CCS) technologies, these emissions can be captured and stored, transforming gray hydrogen into blue hydrogen. Green hydrogen produced through electrolysis and blue hydrogen through steam methane reforming with CCS are both essential in the transition to a hydrogen economy.
