NOVELTY - A hydrogen storing and fuelling system has hydrogen source (1) for supplying hydrogen with pressure of 300 Bar, an intermediate storage (2) of at least a cylinder accommodating hydrogen gas, a unit for fuelling hydrogen having a multi-jacketed insulated cylinder (4) and a carbonaceous material inside the insulated cylinder, treated by impregnating with precious metal which is reduced by hydrogenation exposing the carbonaceous material to pressure of 300 Bar, and cooling the contents at 76-38K. The carbonaceous material has a bulk density of 0.1-0.3 gm/cc.    USE - System is used for storing and fuelling hydrogen for fuel cell and internal combustion engine.    ADVANTAGE - The hydrogen storing and fuelling system has high storage efficiency.    DETAILED DESCRIPTION - A system for effective storing and fuelling of hydrogen has hydrogen source for supplying hydrogen with pressure of 300 Bar, an intermediate storage of at least a cylinder accommodating hydrogen gas maintained at 76-38 K and pressure of 300 Bar, a unit for fuelling hydrogen having a multi-jacketed insulated cylinder and a carbonaceous material inside the insulated cylinder, duly treated by impregnating with at least a precious metal which is duly reduced by hydrogenation exposing the carbonaceous material to pressure of 300 Bar, and cooling the contents at 76-38K, such that the coils are included inside the intermediate storage and the multi-jacketed insulated cylinder through which helium gas is circulated in closed circuit. The carbonaceous material has a bulk density of 0.1-0.3 gm/cc and surface area of 4000 sq mt/gm. The carbonaceous material is carbon novoloid micro fiber which is carbon wool. The precious metal is palladium or ruthenium nano particles. The insulating material is super perlite or aluminized mylar.
