Liquid hydrogen

Liquid hydrogen is hydrogen gas cooled to extremely low temperatures, making it turn into a clear, pale-colored liquid. It’s very lightweight and energy-dense, meaning it can store a lot of energy relative to its volume. Because of its properties, liquid hydrogen is used as a clean fuel for rockets, powering spacecraft without emitting pollutants. Handling it requires special insulation and precautions since it’s extremely cold and flammable. Its potential as a renewable energy source lies in its ability to produce zero emissions when used, making it a promising option for sustainable energy and transportation solutions.
