Green hydrogen, also known as renewable hydrogen, is hydrogen produced by utilizing renewable energy sources. It involves the electrolysis of water, wherein an electric current splits water molecules into hydrogen (H2) and oxygen (O2). The electricity used in this process is generated from renewable sources such as solar, wind, or hydro power, ensuring a zero-carbon footprint.
Applications of Green Hydrogen:

Energy Storage: Green hydrogen can serve as an excellent means of storing surplus renewable energy generated during periods of low demand. The excess electricity is used to produce hydrogen through electrolysis, which can later be converted back to electricity or used as a clean fuel for various applications.

Transportation: Green hydrogen holds significant potential for decarbonizing transportation. Hydrogen fuel cell vehicles (FCVs) can use hydrogen to produce electricity, emitting only water vapor as a byproduct. FCVs offer long driving ranges, fast refueling times, and zero tailpipe emissions, making them a viable alternative to conventional internal combustion engine vehicles.

Industry and Manufacturing: Many industrial processes rely on hydrogen as a feedstock or energy source. Green hydrogen can replace fossil-fuel-derived hydrogen, reducing carbon emissions in sectors such as steel production, ammonia production, and refineries. By transitioning to green hydrogen, industries can contribute to a greener and more sustainable economy.

Power Generation: Green hydrogen can be used to generate electricity in fuel cells, providing a dispatchable and clean energy source. This can help balance the intermittent nature of renewable energy sources, ensuring a stable and reliable power supply.
