Abstract
A hydrogen storage system for detecting and restricting a pressure difference generated in the hydrogen storage system and a method for adjusting differential pressure therein are provided. The hydrogen storage system includes a controller that controls valves of a plurality of tanks. The controller measures pressure for each tank, measures a pipe pressure of pipe connected with the plurality of tanks, compares the pressure for each tank with the pipe pressure to determine whether differential pressure between the tank and the pipe is generated, determines whether it is expected to generate differential pressure between the tanks in an expected equilibrium temperature, when it is determined that the differential pressure between the tank and the pipe is not generated, and performs pressure equilibrium control between the tanks, when it is expected to generate the differential pressure between the tanks.
