Green hydrogen is hydrogen produced through the process of electrolysis, generated by renewable energy sources, such as solar or wind, or from low-carbon power. Unlike grey hydrogen which is usually produced from fossil fuels, green hydrogen is a zero-emission fuel which does not release any greenhouse gases into the atmosphere. In simple terms, it is an eco-friendly fuel. The supply of green hydrogen is virtually unlimited as it can be produced and transported anywhere in the world. Green hydrogen is clean and sustainable and has the potential to transform the energy infrastructure globally, which currently relies heavily on fossil fuels. Due to innovations in the production of green hydrogen production, the eco-friendly fuel is being manufactured at a reasonable cost with respect to its energy density. In different regions, the cost of hydrogen varies broadly in the range of 0.8 to 4 USD per kilogram.
