Hydrogen, often termed the fuel of the future, stands at the forefront of the global energy transition. As the world grapples with the imperative to reduce carbon emissions and combat climate change, hydrogen emerges as a pivotal player, offering a clean, versatile, and sustainable energy solution. Unlike traditional fossil fuels, hydrogen, when used as an energy vector, emits only water vapor, making it an environmentally benign option. Its potential to revolutionize energy systems across multiple sectors—transportation, industry, and power generation—underscores its significance in the quest for a greener future.
