Hydrogen is being explored as a clean energy option to reduce carbon emissions from fossil fuels. Researchers are investigating how to use hydrogen as a fuel for various applications like heat, power generation, and long-distance energy transport. They are developing technologies to store and utilize hydrogen efficiently. As renewable energy sources rely on specific environmental conditions, hydrogen's versatility makes it a promising energy carrier. Hydrogen infrastructure and related technologies are rapidly advancing, hinting at a possible future where hydrogen plays a significant role in the global energy landscape. The idea of a hydrogen economy, where hydrogen is widely used for energy needs, is gaining traction, although it is still in the early stages of becoming a reality.
