FIELD: chemistry of metal hydrides, more particularly prolonged storage of hydrogen in chemically bonded state. SUBSTANCE: vanadium is heated to 593-793 K. Pressure is maintained at not higher than 1.3 Pa. Vanadium is kept at above-indicated temperature and pressure and hydrogen isotope is then fed at pressure of (3,5-10)x105 Pa to give vanadium hydride containing 367-378 cubic cm/g of hydrogen. EFFECT: simplified technology due to lower process temperatures and decreased vacuum parameters. 2 ex, 1 tbl
