Hydrogen energy is a clean and versatile form of energy produced using renewable resources through water electrolysis, which splits water into hydrogen and oxygen using excess renewable electricity from sources like wind and solar. The generated hydrogen can be stored in large-scale facilities for long-term use or in batteries for short-term storage. It can then be converted back into electricity through gas power plants or conversion inverters, providing a stable and reliable power supply. This process supports the integration of renewable energy into the power grid, enhances energy security, and helps mitigate climate change by reducing greenhouse gas emissions.
