=Hydrogen=



**Hydrogen is a non metal and its is a gas.**
===**In 1766, hydrogen was detected for the first time as a new gas. Henry Cavendish had the idea to decompose vapour with a very hot iron bar. In this decompose process arose the so called //Hydrogene// (v. Gr. Hudoor=water, Gennaoo=generate) or waterforming material, which was translated as hydrogen. **===

**Hydrogen companies and research and development groups for the production, transport, and usage of hydrogen as a clean energy carrier. Hydrogen is also used as a fuel**
