  I don't have an answer for this but can't wait to see other's ideas.

  Space tanks? connected with pipes to small tanks on earth as buffers, but don't know connection speed I mean the way Hydrogen would move up to the space tank & it's speed.

  You need to compress it. Te higher the pressure the lower the volume you require. 11m3 for 1kg is at STP. You would definitely not store it under these conditions as the cost of the vessel would be greater than the cost of the gas 😀

  department of energy US is working on a project actively regarding using hydrogen as an energy carrier for future,and hydrogen storage is the most important prospect of this,several methords are proposed regarding h2 storage but the most promising one is storing h2 in metal hydrides,anybdy need information can contact at
  and guys plz dont give silly answers..

  Commercial hydride vessels operate at 10 bar. Desorption is achieved by pressure swing 😀

  I also think so.

  Why do you think it can't be stored in a small space?
  Can't it be compressed?

  No idea about this thing.

  Hydrogen is a permanent gas. Can be compressed to any extent. Cost of compressing and storage can be high. A lot of research is going into reversible absorption.

  I wanna store it in ice. just like methane can be stored in it. in the north and in the south, there are places (I mean the arctic and the antarctic) where ice can exist naturally and which are practically wastelands. I realize this sounds sorta crazy. I back it up with two links.

  The nanotubes can condense and safely store high volumes of hydrogen in a small space

  by compression... v can also do this by creating a vacuum in d vessel...

  If you compress hydrogen above a certain point it will spontaneously explode. It is a very risky game. Check out Bob Lazars website unitednucleardotcom, his product is a metal tube you fill with hydrogen under no pressure. The tube is made of a metal that is able to suck up hydrogen the same way a sponge sucks up water. When heating the metal to a point below 60 degrees celsius the metal releases the hydrogen accordig to Bob. His car runs only on hydrogen and he claims there is aboslutely no risk for explosion.

  I have contacted the administrator to delete my sentence regarding spontenous explosion of hydrogen under pressure, my misstake.

  That is right. What does happen is that when highly compressed hydrogen is suddenly released into air auto ignition can happen.
  
  

  Spontaneous Ignition of Pressurized Releases of Hydrogen and Natural Gas into Air​

  Abstract: This paper demonstrates the ‘‘spontaneous ignition’’ (autoignition=inflammation and sustained diffusive combustion) from sudden compressed
  hydrogen releases that is not well documented in the present literature, for which
  little fundamental explanation, discussion or research foundation exists, and
  which is apparently not encompassed in recent formulations of safety codes
  and standards for piping, storage, and use of high pressure compressed gas systems handling hydrogen. Accidental or intended, rapid failure of a pressure
  boundary separating sufficiently compressed hydrogen from air can result in
  multi-dimensional transient flows involving shock formation, reflection, and
  interactions such that reactant mixtures are rapidly formed and achieve chemical
  ignition, inflammation, and transition to turbulent jet diffusive combustion, fed
  by the continuing discharge of hydrogen. Both experiments and simple transient
  shock theory along with chemical kinetic ignition calculations are used to support
  interpretation of observations and qualitatively identify controlling gas properties
  and geometrical parameters. Although the phenomenon is demonstrated for pressurized hydrogen burst disk failures with different internal flow geometries, similar phenomena apparently do not necessarily occur for sudden boundary failures
  of storage vessel or transmission piping into open air that have no downstream
  obstruction. However, subsequent reflection of the resulting transient shock from
  surrounding surfaces through mixing layers of hydrogen and air may have the potential for producing ignition and continuing combustion. Much more experimental and computational work is required to quantitatively determine the envelope of parameter combinations that mitigate or enhance spontaneous ignition
  characteristics of compressed hydrogen as a result of sudden release, particularly
  if hydrogen is to become a major energy carrier interfaced with consumer use.
  Similar considerations for compressed methane, for mixtures of light hydrocarbons and methane (simulating natural gas), and for larger carbon number hydrocarbons show similar autoignition phenomena may occur with highly compressed
  methane or natural gas, but are unlikely with higher carbon number cases, unless
  the compressed source and=or surrounding air is sufficiently pre-heated above
  ambient temperature. Spontaneous ignition of compressed hydrocarbon gases is
  also generally less likely, given the much lower turbulent blow-off velocity of
  hydrocarbons in comparison to that for hydrogen.
