What is Green Hydrogen & How it is useful ?

Green hydrogen refers to hydrogen gas produced through a process called electrolysis, where water (H2O) is split into hydrogen (H2) and oxygen (O2) using electricity. The electricity used in this process is generated from renewable sources such as solar, wind, or hydropower, hence the term "green." The hydrogen produced through this method is considered environmentally friendly because it doesn't produce carbon emissions during its production or use.

Green hydrogen has several useful applications:

Decarbonizing Energy Systems: Green hydrogen can be used as a clean energy carrier to decarbonize various sectors that are challenging to electrify directly, such as heavy industries, long-haul transportation, and heating. It can be used as a substitute for fossil fuels, thereby reducing greenhouse gas emissions.

Energy Storage: Green hydrogen can be stored and used as a form of energy storage. Excess renewable energy generated during periods of high production can be used to produce hydrogen, which can be stored and later converted back into electricity when energy demand is high or renewable generation is low. This helps to balance the intermittent nature of renewable energy sources.

Industrial Processes: Hydrogen is a crucial ingredient in various industrial processes, such as ammonia production, steel manufacturing, and petroleum refining. By replacing hydrogen produced from fossil fuels with green hydrogen, these processes can become more environmentally friendly and reduce their carbon footprint.

Fuel Cell Vehicles: Green hydrogen can be used as fuel for fuel cell vehicles (FCVs). Fuel cells convert hydrogen into electricity, which powers the vehicle's motor, producing only water vapor as a byproduct. FCVs offer a zero-emission alternative to conventional internal combustion engine vehicles.

Energy Export: Green hydrogen can be transported and used as an energy export commodity, similar to liquefied natural gas (LNG). Countries with abundant renewable energy resources can produce green hydrogen and export it to regions lacking such resources, enabling them to reduce their reliance on fossil fuels.

Overall, green hydrogen plays a vital role in the transition to a sustainable and low-carbon future by offering an alternative energy carrier that can replace fossil fuels and contribute to decarbonizing various sectors of the economy.
