answered-by-expert Expert Answer
Hydrogen is found in free state as well as in combined  state.
1.In free state, it is found in traces in the earth's crust and atmosphere. On the sun and bright stars, hydrogen is very abundant.It is suggested that the source of sun's energy is fusion of hydrogen to helium.
2.In combined state it is found in the compounds like water, acids, organic materials and minerals. Natural gas coming out from oil wells, coal mines and volcanoes invariably contains this gas.
