Common energy sources (chemical, nuclear, thermonuclear) currently in use or proposed for fueling a spacecraft have one feature in common: only a small fraction of their total mass-energy is extracted, and the leftover is a waste. As a result, none is capable of accelerating deep-space rockets to relativistic speed so that even the nearest stars stay beyond the range of reach for a reasonable time-of-flight. The only hope is matter-antimatter annihilation which can be used in two ways: propulsion by annihilation products and propulsion by relativistic ions from the accelerators powered by annihilation reactor. The use of annihilation energy for propulsion requires antimatter storage onboard, and a large amount of it in liquid or solid state to ensure its highest energy density. The prospects of diamagnetic antihydrogen storage in a container with a thin magnetic barrier near its internal wall are discussed in this report. The non-potential energy barriers, in which magnetic field diminishes with the distance from the wall, can be created by arrays of current-carrying loops with alternate direction of current. Various arrays are modelled to produce containers of different geometries. The level of stored antihydrogen as a function of rocket acceleration and magnetic field strength is estimated. The problem of hazardous antihydrogen vapors is discussed.
