The Hydrogen Economy refers to a system where hydrogen is used as a clean energy source, replacing fossil fuels in various applications. Hydrogen can be produced from water, natural gas, or biomass, and when used in fuel cells, it generates electricity with water as the only byproduct. This makes it an environmentally friendly alternative for powering vehicles, heating buildings, and generating electricity. In a Hydrogen Economy, infrastructure would be developed to produce, store, and distribute hydrogen efficiently. This includes advancements in technologies like fuel cells and electrolysis, which can help reduce greenhouse gas emissions and reliance on non-renewable energy sources, contributing to a more sustainable future.
