We can compress the hydrogen because hydrogen gas is stored in the cylinders.
Its stored in a liquefied state just to conserve the storage space
The energy in a sucrose molecule is stored in the interatomic bonds such as the carbon-oxygen bonds and the oxygen-hydrogen bonds.
Hydrogen peroxide, which has the formula H2O2, is preferably stored in dark coloured bottles because visible light can catalyze the decomposition of the peroxide to water and oxygen.
The primary hazard from hydrogen is fire, as it burns with an invisible flame. Hydrogen is stored in pressurized containers, so there is also a hazard associated with container leaks and the effects of pressure release (explosion or high velocity projectile motion). Hydrogen can also make other metal more brittle, degrading the strength of structures and containers.

Hydrogen is a gas at ordinary temperatures and pressures, and is therefore normally stored in compressed gas cylinders. It's also possible to store it in the form of metal hydrides, which allows for a greater storage density. In cases where power isn't a concern, it can be more practical to generate hydrogen as needed by electrolysis of water rather than attempting to store it.

Many gases are filled in cylinders and include nitrogen, Carbon Dioxide, Helium, Hydrogen, Argon, Acetylene etc. Small cylinders that are extremely portable include butane etc.
Because all the gas could come out
Pure Oxygen is stored either as a gas in high pressure gas cylinders or as a liquid in large cryogenic tanks. Highly Flammable. :)

Information is stored in the computer's hard drive, which is a magnetic disk read by lasers.
