Green hydrogen is a clean energy source produced by using renewable energy, such as solar or wind, to split water into hydrogen and oxygen through a process called electrolysis. Unlike traditional hydrogen production methods that rely on fossil fuels, green hydrogen generates no carbon emissions, making it an environmentally friendly option. This versatile fuel can be used in various applications, including powering vehicles, generating electricity, and providing heat for industrial processes. As countries aim to reduce their carbon footprints and transition to sustainable energy systems, green hydrogen is gaining attention as a key player in the fight against climate change.
