Of fewer 253 degree C 20 degrees K also cannot be kept liquid at greater than minus 240 degrees C 37 degrees K , even at high pressure maximum at 12.4 barg or 195 psig. dryly, wet contains extra than 50 percent more hydrogen atoms for every level than do liquid hydrogen (H2).
Hydrogen gas's corrosion co would be makes it really inflammable more a thick collection of concentrations. Hydrogen burns more very much than petrol , save for hydrogen's unstable budding is compact in its cheerfulnem , which results in rapid dispersal.

because the lightest of every one molecules, hydrogen has the top power thickness, sense to it contains added element energy per load than one new body . This latent lead is compact, but , via its little volumetric energy density as either a gas or liquid. Even as a liquid, hydrogen has only about 7 percent of the density of gasoline. This low density means that large volumes are compulsory for storing substantial amounts of energy (hydrogen has a very low “energy density;” see Table 1). Furthermore, hydrogen's volatility and propensity to leak through small openings necessitates additional weight for its containment as either a highly compressed gas or cryogenic liquid.
Hydrogen liberates about 2.5 times the amount of energy during its reaction than the heat of combustion of common hydrocarbon fuels (gasoline, diesel, methane, propane, etc.) on a mass (weight) basis. Therefore, a given energy requirement requires a mass of hydrogen only about a third of the mass of hydrocarbon fuel needed. But volumetrically, hydrogen's energy density is poor (since it has such a low density), even though its energy-to-weight ratio is the best of all fuels (because it is so light). Table 1 shows the energy density of common energy carriers (fuels).
Alternative containment and transport methods under investigation include sorption onto “hydrates,” storage in other chemicals (such as sodium borohydride), or storage in “nanotubes.” These have the prospect of increasing the amount of hydrogen per volume, but so far they have greatly added to the total weight of the total fuel material. Commercially suitable alternatives have not yet been fully demonstrated. For stationary uses (e.g., building combined heat and power), however, the volume of the hydrogen storage creates less of a problem.
Hydrogen is only as “green” as the energy sources used to produce it. Traditional sources of hydrogen include electrolysis of water, “reforming” of hydrocarbons, and its separation from intermediary steps of various chemical reactions (e.g., in coal or biomass gasification).
