Apparatus for generating electric energy using hydrogen storage alloy |
(57) An electric generator (4) operatively connected to a gas turbine (3) is driven by
driving the gas turbine (3) with high pressure hydrogen (8) released from a hydrogen
storage alloy which is contained in a first zone (1) and which is heated by indirect
heat exchange (5) with a heating medium (18) while reabsorbing the hydrogen discharged
from the gas turbine (3) in a hydrogen storage alloy which is contained in a second
zone (2) and which is cooled by indirect heat exchange (6) with a cooling medium (19).
By switching the flows of the heating and cooling media alternately, an electric energy
may be continuously obtained from the electric generator (4). The electric generator
(4) is characterized by the provision of means preheating and cooling of the hydrogen
whereby a steady level of electric energy can be generated.
